The control of beginning position consistency.Air conditioning control device 50 after step sloo, every controlling cycle is repeated from step
The processing of S110 to step S230.
In step s 110, mode of operation of the occupant for operation panel 60 is obtained.Next, in the step s 120, reading
Enter each sensor signal of the sensor group of airconditioning control.
Next, in step s 130, based on the various states and various letters read in the processing of step S110, S120
Number, calculate the temperature i.e. target blowout temperature TAO of the wind pushing air blown out into car room.
Specifically, in the processing of step S130, target blowout temperature TAO is calculated using mathematical expression below.TAO=
Kset×Tset-Kr×Tr-Kam×Tam-Ks×As+C.Here, Tr is the inside temperature detected by interior gas sensor.Separately
Outside, Tam is the outside air temperature detected by outer gas sensor.As indicates the insolation amount detected by insolation sensor.In addition,
Kset, Kr, Kam and Ks are the control gains of positive value, and C is the constant of amendment.
Next, in step S140, the draft capacity of air blower 33 is determined.In the processing of step S140, it is based on

Specifically, air conditioning control device 50 blows out temperature TAO to determine to rouse according to mapping shown in fig. 5, according to target
Horizontal fan.Blower level is the index for the draft capacity for indicating air blower 33.Blower level is bigger, then centrifugal fan
The rotating speed of 33a is bigger.Therefore, blower level is bigger, then the draft capacity of air blower 33 is higher.
Hereinafter, illustrating the behavioral illustrations of mapping shown in fig. 5.It is in temperature T1 (such as -20 in target blowout temperature TAO
DEG C) in the case of extremely low temperature range below, blower level become the maximum.In addition, being temperature T1 in target blowout temperature TAO
More than (such as -20 DEG C) and in the case of temperature T2 (such as 15 DEG C) is below, blower level is from peak to peak, with mesh
The rising of mark blowout temperature TAO together, blows out temperature TAO corresponding to target and linearly declines.In addition, blowing out temperature in target
TAO be temperature T2 or more and T3 (such as 40 DEG C) it is below in the case of, blower level become minimum.In addition, being blown in target
Go out temperature TAO be temperature T3 or more and temperature T4 (such as 75 DEG C) it is below in the case of, blower level is from minimum value to maximum
Value blows out temperature TAO corresponding to target and linearly increases together with the rising of target blowout temperature TAO.In addition, in target
In the case that blowout temperature TAO is in the high temperature range of temperature T4 or more, blower level become the maximum.
Therefore, as the whole tendency of mapping shown in fig. 5, it is less than the feelings of median T2 in target blowout temperature TAO
Under condition, it is higher more reducing then blower level that target blows out temperature TAO.In addition, being higher than median T3 in target blowout temperature TAO
In the case of, it is higher more increasing then blower level that target blows out temperature TAO.
In addition, as described above, target blowout temperature TAO and set temperature Tset has positive correlation.More specifically, with mesh
The relevant partial differentials of set temperature Tset of mark blowout temperature TAO are positive values.Accordingly, with respect to set temperature Tset, there is also certain
A first reference value, set temperature Tset are bigger less than the more big then blower level of amount of a reference value.In addition, about setting
Temperature Tset there is also some the second a reference value, set temperature Tset be more than a reference value the more big then blower level of amount more
It is high.First reference value can be value identical with the second a reference value, might be less that the second a reference value.
For example, set temperature Tset becomes Hi (the i.e. upper limits by by operation of the occupant to temperature setting switch 60c
Value) in the case of, TAO becomes the value in above-mentioned high temperature range sometimes.In addition for example, by occupant to temperature setting switch
In the case that the operation of 60c and set temperature Tset become Lo (i.e. lower limiting value), TAO becomes in above-mentioned extremely low temperature range sometimes
Value.
Then, in step S150, the suction inlet pattern for indicating the switching state of inside and outside autogenous cutting changing device 32 is determined.In step
In the processing of rapid S150, suction inlet pattern is set as interior gas pattern always.
Then, in step S160, blow-off outlet pattern is determined.In the processing of step S160, based in step s 130

The blow-out mode that blow-off outlet opening and foot's blow-off outlet and frost removal blow-off outlet are plugged.Foot's pattern is that foot's blow-off outlet opens
And the blow-out mode that face's blow-off outlet and frost removal blow-off outlet are plugged.Frost removal pattern is the opening of frost removal blow-off outlet and face
The blow-out mode that blow-off outlet and foot's blow-off outlet are plugged.B/L patterns are face's blow-off outlet and foot's blow-off outlet this two side opening
And the blow-out mode that frost removal blow-off outlet is plugged.
Air conditioning control device 50 blows out temperature TAO to determine blow-off outlet pattern according to mapping shown in fig. 6, according to target.
Hereinafter, the characteristic mapped shown in definition graph 6.In the case where target blowout temperature TAO is less than temperature T5, blow-off outlet pattern becomes
Face's pattern.Target blowout temperature TAO be temperature T5 less than temperature T6 in the case of, blow-off outlet pattern becomes B/L
Pattern.In the case where target blowout temperature TAO is temperature T6 or more, blow-off outlet pattern becomes foot's pattern.
For example, set temperature Tset becomes Hi (the i.e. upper limits by by operation of the occupant to temperature setting switch 60c
Value) in the case of, TAO becomes the value of temperature T6 or more sometimes.In addition for example, by occupant to temperature setting switch 60c's
Operation and set temperature Tset become Lo (i.e. in the case of lower limiting value, sometimes TAO become be less than temperature T5 value.
In addition, temperature T5, T6 can be fixed value, fixed value may not be.For example, temperature T5, T6 can also basis
The value of the blow-off outlet pattern determined in a upper controlling cycle avoids blow-off outlet pattern stagnant as continually changing to realize
The mode acted on afterwards changes.Specifically, can be, when the blow-off outlet pattern determined in a upper controlling cycle is B/L moulds
In the case of formula, the value of temperature T5 is smaller compared with the case where being face's pattern.Furthermore it is possible to be, it is all when being controlled at upper one
In the case that the blow-off outlet pattern of interim decision is foot's pattern, compared with the case where being B/L patterns, the value of temperature T6 is smaller.
Then, in step S170, the operational mode of air conditioner for vehicles 1 is determined.In the processing of step S170, base
It determines in the outside air temperature read in the step s 120 and internal temperature and the target blowout temperature TAO calculated in step s 130
Determine blow-off outlet pattern.
Specifically, in step S170, as shown in fig. 7, first in step S171, whether judgement outside air temperature is less than
Force heating threshold value Td1.S172 is entered step less than in the case of forcing heating threshold value Td1 (such as 10 DEG C) in outside air temperature,
S173 is entered step not less than heating threshold value Td1 is forced.In step S172, operational mode is determined as heating
Then pattern terminates the processing of decision operational mode.
In addition, it can be fixed value to force heating threshold value Td1, fixed value may not be.For example, forcing heating threshold value
Td1 can also avoid operational mode from continually becoming according to the value of the operational mode determined in a upper controlling cycle to realize
The mode for changing such hysteresis changes.Specifically, can be, when the operational mode determined in a upper controlling cycle
In the case of being refrigeration mode, compared with the case where being heating mode, force heating threshold value Td1 smaller.
In step S173, whether judgement outside air temperature is higher than forced refrigeration threshold value Td2 (such as 28 DEG C).Forced refrigeration threshold
Value Td2 is above the temperature for forcing heating threshold value Td1.Enter step in the case where outside air temperature is higher than forced refrigeration threshold value Td2
Rapid S174 enters step S175 not higher than forced refrigeration threshold value Td2.In step S174, operational mode is determined
It is set to refrigeration mode, then terminates the processing of decision operational mode.
In addition, forced refrigeration threshold value Td2 can be fixed value, fixed value may not be.For example, forced refrigeration threshold value
Td2 can also avoid operational mode from continually becoming according to the value of the operational mode determined in a upper controlling cycle to realize
The mode for changing such hysteresis changes.Specifically, when the operational mode determined in a upper controlling cycle is heating
In the case of pattern, compared with the case where being refrigeration mode, forced refrigeration threshold value Td2 is larger.
In step S175, temperature TAO is blown out based on inlet temperature and target, and according to the figure for being pre-stored within memory
It is mapped shown in 8 to determine operational mode.
Inlet temperature be from the introducing port of interior gas and the introducing port of outer gas import in air-conditioner housing 31 after and to indoor evaporation
The temperature of air before the sucking of device 19.Therefore, inlet temperature changes according to above-mentioned interior gas ratio.For example, gas pattern inside
In the case of, inlet temperature is almost the same with internal temperature degree.In addition for example, in the case of outer gas pattern, inlet temperature with
Outside air temperature degree is almost the same.
Inlet temperature can also be detected by the dedicated sensor for detecting inlet temperature.Alternatively, inlet temperature
Detected value that can be based on interior gas sensor, the detected value of outer gas sensor and interior gas ratio and calculate.
Hereinafter, illustrating the characteristic of mapping shown in Fig. 8.Temperature T7 in mapping is 5 DEG C of temperature lower than inlet temperature, temperature
It is 5 DEG C of temperature higher than inlet temperature to spend T8.In the case where target blowout temperature TAO is less than temperature T7, operational mode becomes
Refrigeration mode.Target blowout temperature TAO be temperature T7 less than temperature T8 in the case of, operational mode become neither
Refrigeration mode nor heating mode air supply pattern.In the case where target blowout temperature TAO is temperature T8 or more, mould is run
Formula becomes heating mode.
Therefore, for qualitatively, target blowout temperature TAO it is higher than inlet temperature to a certain degree in the case of, run mould
Formula become heating mode, target blowout temperature TAO it is lower than inlet temperature to a certain degree in the case of, operational mode become refrigeration
Pattern.Also, in the case where target blows out temperature TAO close to inlet temperature, operational mode becomes air supply pattern.
In addition, the value of temperature T7, T8 can be dependent only on the amount of inlet temperature, can also be dependent on inlet temperature and
The amount of other amounts.For example, temperature T7, T8 can also also be dependent on the value of the operational mode determined in a upper controlling cycle,
It is changed in a manner of realizing and operational mode is avoided continually to change such hysteresis.
More specifically, Ke Yishi, in the case of selecting refrigeration mode in the step S175 of a upper controlling cycle,
Temperature T7 becomes 3 DEG C of value lower than inlet temperature, when selection heating mode in the step S175 in a upper controlling cycle or send
In the case of wind pattern, temperature T7 becomes 5 DEG C of value lower than inlet temperature.And it is possible to be, when in a upper controlling cycle
In the case of selecting refrigeration mode or air supply pattern in step S175, temperature T8 becomes 5 DEG C of value higher than inlet temperature, when upper
In the case of selecting heating mode in the step S175 of one controlling cycle, temperature T8 becomes 3 DEG C of value higher than inlet temperature.
Then, in step S180, based on the operational mode determined in step S170, to determine high-pressure side open and close valve

It is set to fully closed, also, the state of triple valve 15 is determined as heating state.In addition, when selecting air supply pattern in step S170
In the case of, the action state of high-pressure side open and close valve 13b and triple valve 15 are intactly determined as present situation.
Then, it in step S190, based on the various signals read in step S110, S120, calculates in step s 130
The operational mode that the target gone out blows out temperature TAO and determined in step S170, to determine the rotating speed Nc of compressor 11.
In the processing of step S190, in the case of selecting refrigeration mode in the processing of step S170, determine as follows

And based on the deviation between goal pressure Phd and discharging refrigerant pressure Ph, so that discharging refrigerant pressure Ph is close to target pressure
The mode of power Phd determines the rotating speed Nc of compressor 11.
In addition, in the processing of step S190, in the case where the processing of step S170 is determined as air supply pattern, will press
The rotating speed of contracting machine is determined as zero.
Then, in step S210, the working condition of ptc heater 24 is determined.Specifically, being less than base in outside air temperature
In the case of quasi- temperature (such as -5 DEG C), decision makes ptc heater 24 work, in the feelings that outside air temperature is the fiducial temperature or more
Under condition, decision does not make ptc heater 24 work.
Then, in step S210, the aperture of A/M doors 35 is determined.Specifically, when being selected in the processing of step S170
In the case of refrigeration mode, as the aperture of A/M doors 35, determine into maximum refrigerating state.In addition, when the processing in step S170

Then, in step S220, it is written over processing.In rewriting processing, to determining from step S140 to step S210
The state or amount of fixed various states and the needs in various amounts change.
It then, will be corresponding with the various states and various amounts determined in step S140~S210 in step S230
Signal etc. is controlled to export to various control devices.As a result, in air conditioner for vehicles 1, realize in step S140~S210
The various states and various amounts determined.
In the usual air-conditioning processing (S3) of present embodiment, control as above is carried out.Therefore, refrigerating circulatory device 10
According to the operational mode selected in step S170, and work as follows.
(A) refrigeration mode
In refrigeration mode, high-pressure side open and close valve 13b is being set as full-gear, by triple valve 15 by air conditioning control device 50
It is set as in the state of refrigerating state, compressor 11 is made to work.Therefore, in refrigeration mode, as shown in the white arrow in Fig. 1,
Discharging refrigerant from compressor 11 flow successively through indoor condenser 12, high-pressure side open and close valve 13b, outdoor heat exchanger 14,
Triple valve 15, low pressure refrigerant access 16, indoor evaporator 19, liquid storage device 22, and sucked again by compressor 11.
Specifically, in refrigeration mode, the discharging refrigerant from compressor 11 is flowed into indoor condenser 12.This
When, the A/M doors 35 under maximum refrigerating state block the air flue of indoor condenser 12, therefore have flowed into indoor condenser 12
Refrigerant is flowed out in the case where hardly being radiated to wind pushing air from indoor condenser 12.
The refrigerant flowed out from indoor condenser 12 is flowed into the case where being hardly depressurized to outdoor heat exchanger 14.
The refrigerant for having flowed into outdoor heat exchanger 14 carries out heat exchange with outer gas and radiates, to cooled.
The refrigerant flowed out from outdoor heat exchanger 14 flowed by low pressure refrigerant access 16, to the second expansion valve 18 and
It is depressurized until becoming low pressure refrigerant.Also, it is flowed from the low pressure refrigerant that the second expansion valve 18 flows out to indoor evaporator 19
Enter, is evaporated from the wind pushing air heat absorption blown by air blower 33.Wind pushing air is cooled as a result, and dehumidifies.
From the refrigerant that indoor evaporator 19 flows out to the inflow of liquid storage device 22 and by gas-liquid separation.Also, in liquid storage device 22
In the vapor phase refrigerant isolated sucked and compressed again by compressor 11.
Here, the liquid phase refrigerant isolated in liquid storage device 22 is as the system for playing the requirement of refrigerating circulatory device 10
The unwanted residual refrigerant of cold energy power institute, and it is accumulated in the inside of liquid storage device 22.This point is also identical in heating mode.
As described above, in refrigeration mode, refrigerant radiates by outdoor heat exchanger 14, passes through indoor steaming
Send out device 19 and refrigerant is evaporated.The wind pushing air blown as a result, into car room is cooled.Hereby it is achieved that the indoor system of vehicle
It is cold.
(B) heating mode
In heating mode, high-pressure side open and close valve 13b is being set as full-shut position, by triple valve 15 by air conditioning control device 50
It is set as in the state of heating state, compressor 11 is made to work.Therefore, in heating mode, such as the arrow with hacures in Fig. 1
Shown, the discharging refrigerant from compressor 11 flows successively through indoor condenser 12, the first expansion valve 13a, outdoor heat exchanger
14, triple valve 15, low pressure bypass 17, liquid storage device 22, and sucked again by compressor 11.
Specifically, in heating mode, flowed into from the high-pressure refrigerant that compressor 11 is discharged to indoor condenser 12.This
When, the A/M doors 35 under maximum heating state make the air flue standard-sized sheet of indoor condenser 12.Therefore, indoor condenser is flowed into
12 refrigerant radiates with by the wind pushing air of indoor evaporator 19 carries out heat exchange.As a result, wind pushing air with
Mode close to target blowout temperature TAO is heated.
Refrigerant is flowed out from indoor condenser 12 to depressurize up to becoming low pressure refrigerant to the first expansion valve 13a inflows.
The low pressure refrigerant flowed out from the first expansion valve 13a is flowed into outdoor heat exchanger 14.Flow into the system of outdoor heat exchanger 14
Cryogen and outer gas carry out heat exchange and absorb heat and evaporate.
The refrigerant flowed out from outdoor heat exchanger 14 is flowed by low pressure bypass 17 to liquid storage device 22, to quilt
Gas-liquid separation.Also, the vapor phase refrigerant isolated in liquid storage device 22 is sucked and compressed again by compressor 11.
As described above, in heating mode, refrigerant radiates by indoor condenser 12, is handed over by outdoor heat
Parallel operation 14 and refrigerant is evaporated.Having passed through the wind pushing air of indoor evaporator 19 as a result, condenser 12 is heated indoors.
Hereby it is achieved that the indoor heating of vehicle.
Here, explaining the rewriting processing in step S220 in detail.In rewriting processing, air conditioning control device 50 executes figure
It is handled shown in 9.First, in step S131, whether judgement outside air temperature is less than above-mentioned pressure heating threshold value Td1.In outside
Temperature enters step S132 in the case of heating threshold value Td1 (such as 10 DEG C) less than pressure, is made not less than pressure in outside air temperature
S133 is entered step in the case of hot threshold value Td1.
Judge whether outside air temperature is higher than above-mentioned forced refrigeration threshold value Td2 (such as 28 DEG C) in step S133.In outside
Temperature enters step S134 in the case of being higher than forced refrigeration threshold value Td2, in outside air temperature not higher than forced refrigeration threshold value Td2's
In the case of enter step S135.
Usually control is executed in step S135.In usual control, what is determined from step S140 to step S210
Any of various states and various amounts do not change, and rewriting processing is made to terminate.
LL controls are determined a need in step S132.Specifically, in step S132, Ke Yishi is blown in target
It is that regulation is judged to needing LL controls when blowing out low temperature X1 or less to go out temperature TAO, is more than when regulation blows out low temperature X1 in TAO and judges
Not need LL controls.Regulation blowout low temperature X1 can be the temperature for the air for being sucked into air-conditioner housing 31, can also be outside
Temperature, i.e. 36 DEG C of target blowout temperature TAO when can also be common heating.
In addition, it is specified that blowout low temperature X1 can also be to realize that the execution for avoiding LL from controlling, non-executing continually change that
The mode of the hysteresis of sample is changed.I.e., it is specified that blowout low temperature X1 can be based in a upper controlling cycle in step
LL controls whether are performed in S136 and are changed.Specifically, can be, when being not carried out LL in a upper controlling cycle
In the case of control, it is specified that blowout low temperature X1 is relatively low compared with the case where performing LL controls.
The set temperature Tset the low, and then target blowout temperature TAO is lower.Therefore, target blowout temperature TAO is based on less than rule
Surely it blows out low temperature X1 and carries out LL controls, thereby, it is possible to execute LL controls in the substantially low ranges of set temperature Tset.Cause
This, can execute LL controls under more effective occasion.
Alternatively, can also be is that regulation is determined as when setting low temperature X2 or less in set temperature Tset in step S132
LL controls are needed, is more than when regulation sets low temperature X2 in set temperature Tset and is judged to not needing LL controls.In this case, it advises
Surely setting low temperature X2 can also be Hi (i.e. upper limit value).
Low temperature X2 being set less than regulation based on set temperature Tset and carrying out LL controls, thereby, it is possible in set temperature
LL controls are executed in range substantially low Tset.Therefore, it is possible to execute LL controls under more effective occasion.
In addition, it is specified that setting low temperature X2 can also be to realize that the execution for avoiding LL from controlling, non-executing continually change that
The mode of the hysteresis of sample is changed.I.e., it is specified that setting low temperature X2 can be based in a upper controlling cycle in step
LL controls whether are performed in S136 and are changed.Specifically, can be, when being not carried out LL in a upper controlling cycle
In the case of control, it is specified that setting low temperature X2 is relatively low compared with the case where performing LL controls.
As already described, in step S170, in the case where outside air temperature is less than heating threshold value Td1 is forced,
No matter how internal temperature, target blowout temperature TAO, set temperature Tset forcibly select heating mode.Such
In the case of, as rare situation, sometimes occupant's operation temperature configuration switch 60c and so that set temperature Tset is reduced to Lo (i.e.
Lower limiting value).In the case where having carried out such operation, it is believed that occupant feels excessively warm in car room, expects that heating dies down.
But if assuming to control without LL, when having carried out operation as described above under situation as described above,
As shown in the row of " the needing LL controls " of Figure 10, maintains heating mode and blow out warm air from face's blow-off outlet with maximum quantity of wind.That is,
The antipodal situation of intention with occupant occurs.
The reason for becoming such is as follows.In the case where set temperature Tset is Lo, target blowout is warm in step s 130
TAO is spent as the value in above-mentioned extremely low temperature range.Then, blower level is set to maximum in step S140.Also, in step
Gas pattern in being selected in rapid S150.Also, in step S160, TAO is less than temperature T5, therefore blow-off outlet pattern becomes face's mould
Formula.In addition, in step S170, outside air temperature is less than pressure heating threshold value Td1, therefore forcibly selection is made as described above
Heat pattern.In addition, in step S210, heating mode is selected, therefore selects maximum heating state.In the past, occurred and multiplied in this way
The antipodal situation of intention of member is the purpose of the system protections such as the frost prevention for having indoor evaporator 19.
Such situation, other than when set temperature Tset is Lo, as described above, being in target blowout temperature TAO
Can also it occur when regulation blows out low temperature X1 or less and when set temperature Tset is regulation setting low temperature X2 or less.
Therefore, air conditioning control device 50 is only blown out in target as the countermeasure for such situation in step S132
Temperature TAO is that regulation is judged to needing LL controls when blowing out low temperature X1 or less.Alternatively, air conditioning control device 50 is as in this way
Situation countermeasure, in step S132, only set temperature Tset be regulation set low temperature X2 or less when be judged to needing LL
Control.In the case where being judged to needing LL controls, S136 is entered step, is being determined as unwanted, is entering step
S135 and select above-mentioned usual control.
In step S136, LL controls are executed.Specifically, to the slave step S140 to S210 in this time controlling cycle
The state and the part in amount of middle decision change.It is determined in the slave step S140 to S210 of this time controlling cycle
State and amount are as shown in the row of " the needing LL controls " of Figure 10.
Also, air conditioning control device 50 is according to the attention switch 600 of hobby configuration part 60d, power down switch 601 and feels
The on-off situation of switch 602 determines the changed content in LL controls.
More specifically, as shown in figure 11, in the case where it is connection to pay attention to switch 600, air conditioning control device 50 can be with
Decision systems disconnect.System disconnection is that compressor 11 and outdoor fan 14a is made to stop.If determining in this way, in next step
In rapid S230, the cycle of the refrigerant in refrigerating circulatory device 10 stops and is sent from room conditioning unit 30 to vehicle is indoor
It becalms only.So, reflection is wanted to inhibit the intention of the occupant of heating to a certain degree, and also functioning to makes occupant notice
Perhaps the effect of maloperation has been carried out.That is, occupant can be made to notice that it is maloperation to reduce set temperature Tset.
In addition, as shown in figure 11, in the case where power down switch 601 is to connect, air conditioning control device 50 is also determined in the same manner
Determine system disconnection.So, reflection is wanted to inhibit the intention of the occupant of heating, and air conditioner for vehicles 1 to a certain degree
Consumption electric power reduce.Useless power consumption caused by work therefore, it is possible to inhibit to deviate the intention of occupant, therefore inhibit
The endurance distance of vehicle declines.
In addition, as shown in figure 11, in the case where power down switch 601 is to connect, air conditioning control device 50 can also determine
The stopping of compressor 11.If determining in this way, in following step S230, refrigerant in refrigerating circulatory device 10 follows
Ring stops.Therefore, not by indoor condenser 12 to from room conditioning unit 30 to the sky of the indoor face's blow-off outlet blowout of vehicle
Gas is heated.So, reflection is wanted to inhibit the intention of the occupant of heating, and air conditioner for vehicles 1 to a certain degree
Consumption electric power reduce.Useless power consumption caused by work therefore, it is possible to inhibit to deviate the intention of occupant, therefore inhibit
The endurance distance of vehicle declines.
In addition, as shown in figure 11, in the case where power down switch 601 is to connect, air conditioning control device 50 can also determine
To make blower level be less than the value in a upper controlling cycle.If determining in this way, in following step S230, centrifugation
The rotating speed of fan 33a declines.Therefore, under the air quantity of the warm air blown out from room conditioning unit 30 to the indoor face's blow-off outlet of vehicle
Drop.So, reflection is wanted to inhibit the intention of the occupant of heating, and the consumption electricity of air conditioner for vehicles 1 to a certain degree
Power is reduced.Useless power consumption caused by work therefore, it is possible to inhibit to deviate the intention of occupant, therefore inhibit vehicle
Endurance distance declines.
In addition, as shown in figure 11, in the case where it is to connect to feel switch 602, air conditioning control device 50 can also determine
To make blower level be less than the value in a upper controlling cycle.So, reflection is wanted to inhibit multiplying for heating to a certain degree
The intention of member, and improve the feeling of occupant.
In addition, as shown in figure 11, in the case where it is to connect to feel switch 602, air conditioning control device 50 can also will be inhaled
Inlet mode from interior gas pattern switching be gas pattern in outer gas pattern or half.Gas pattern, which is interior gas ratio, in half becomes 1：1 mould
Formula.
If determining in this way, in following step S230, the outer gas of low temperature is imported into room conditioning unit 30.Cause
This, the temperature of the air blown out from room conditioning unit 30 to the indoor face's blow-off outlet of vehicle declines to a certain degree.So,
Reflection is wanted to inhibit the intention of the occupant of heating to a certain degree, and improves the feeling of occupant.
In addition, as shown in figure 11, in the case where it is to connect to feel switch 602, air conditioning control device 50 can also be by A/M
The aperture of door 35 is determined as the state other than maximum heating state.That is, make by it is in the wind pushing air after indoor evaporator 19,
By the air quantity of indoor condenser 12 relative under the air quantity ratio (that is, warm wind ratio) of the air quantity around indoor condenser 12
Drop.
As the state other than maximum heating state, there are maximum refrigerating state and intermediate state.
Intermediate state is the air quantity by indoor condenser 12 and the air quantity between the air quantity by cold wind bypass 34
Ratio is the state less than upper limit value and more than lower limiting value.For example, being bypassed with by cold wind by the air quantity of indoor condenser 12
Air quantity ratio between the air quantity of access 34 is 1：1 state is intermediate state.
If determining in this way, in following step S230, the whole in wind pushing air in room conditioning unit 30
Or it is blown out into car room around indoor condenser 12 with part.Therefore, it is blown from room conditioning unit 30 to the indoor face of vehicle
The temperature for exporting the air of blowout declines to a certain degree.So, reflection is wanted to inhibit the meaning of the occupant of heating to a certain degree
Figure, and improve the feeling of occupant.
In addition, air conditioning control device 50 may correspond to pay attention to switch 600, power down switch 601, feel switch 602
The various combinations of on-off and above-mentioned processing is combined.For example, it may be paying attention to switch 600 and power down switch
601 be in the case of connecting and feeling that switch 602 is disconnection, system to be selected to disconnect.Furthermore it is possible to be, in 601 He of power down switch
Feel that switch 602 is in the case of connecting and paying attention to that switch 600 is disconnection, to be determined as making the work of compressor 11 to stop and make
Blower level is less than the value in a upper controlling cycle.Air conditioning control device 50 makes rewriting processing eventually after step S136
Only.
In step S134, HH controls are determined a need for.Specifically, in step S134, Ke Yishi is blown in target
It is that regulation is judged to needing HH controls when blowing out high temperature Y1 or more to go out temperature TAO, is less than when regulation blows out high temperature Y1 in TAO and judges
Not need HH controls.Regulation blowout high temperature Y1 can be the temperature for the air for being sucked into air-conditioner housing 31, can also be outside
Temperature, i.e. 30 DEG C of target blowout temperature TAO when can also be common refrigeration.
In addition, it is specified that blowout high temperature Y1 can also be to realize that the execution for avoiding HH from controlling, non-executing continually change that
The mode of the hysteresis of sample is changed.I.e., it is specified that blowout high temperature Y1 can be based in a upper controlling cycle in step
HH controls whether are performed in S137 and are changed.Specifically, can be, when being not carried out HH in a upper controlling cycle
In the case of control, it is specified that blowout high temperature Y1 higher compared with performing the case where executing HH controls.
The set temperature Tset the high, and then target blowout temperature TAO is higher.Therefore, target blowout temperature TAO is based on higher than rule
Surely it blows out high temperature Y1 and carries out HH controls, thus, it is possible to execute HH controls in the very high ranges of set temperature Tset.Therefore,
HH controls can be executed under more effective occasion.
Alternatively, can also be is that regulation is determined as when setting high temperature Y2 or more in set temperature Tset in step S134
HH controls are needed, is less than when regulation sets high temperature Y2 in set temperature Tset and is judged to not needing HH controls.In this case, it advises
Surely setting high temperature Y2 can also be Lo (i.e. lower limiting value).
High temperature Y2 being set higher than regulation based on set temperature Tset and carrying out HH controls, thus, it is possible in set temperature Tset
LL controls are executed in very high range.Therefore, it is possible to execute HH controls under more effective occasion.
In addition, it is specified that setting high temperature Y2 can also be as realizing that the execution for avoiding HH from controlling, non-executing continually change
The mode of hysteresis changed.I.e., it is specified that setting high temperature Y2 can be based in a upper controlling cycle in step
HH controls whether are performed in S137 and are changed.Specifically, can be, when being not carried out HH in a upper controlling cycle
In the case of control, it is specified that setting high temperature Y2 higher compared with the case where performing HH controls.
As already described, in step S170, in the case where outside air temperature is higher than forced refrigeration threshold value Td2,
No matter how internal temperature, target blowout temperature TAO, set temperature Tset forcibly select refrigeration mode.Such
In the case of, as rare situation, sometimes occupant's operation temperature configuration switch 60c and so that set temperature Tset is improved to Hi (i.e.
Upper limit value).In the case where having carried out such operation, it is believed that occupant feels supercooling in car room, it is therefore contemplated that refrigeration dies down.
But if assume to control without HH, when situation as described above has carried out operation as described above, such as
Shown in the row of " the needing HH controls " of Figure 10, refrigeration mode is maintained and from foot's blow-off outlet with maximum quantity of wind blowing cold air.That is, hair
The raw antipodal situation of intention with occupant.
The reason for becoming such is as follows.In the case where set temperature Tset is Hi, target blowout is warm in step s 130
TAO is spent as the value in above-mentioned high temperature range.Then, blower level is set to maximum in step S140.Also, in step
Gas pattern in being selected in rapid S150.Also, in step S160, TAO is higher than temperature T6, therefore blow-off outlet pattern becomes foot's mould
Formula.In addition, in step S170, outside air temperature is higher than forced refrigeration threshold value Td2, therefore forcibly selection is made as described above
Chill formula.In addition, in step S210, refrigeration mode is selected, therefore selects maximum refrigerating state.In the past, occurred and multiplied in this way
The complete inverse situation of intention of member is that the load of compressor 11 in order to prevent is excessively high.
Such situation, other than when set temperature Tset is Hi, as described above, being in target blowout temperature TAO
Can also it occur when regulation blows out high temperature Y1 or more and when set temperature Tset is regulation setting high temperature Y2 or more.
Therefore, air conditioning control device 50 is as the countermeasure for such situation, in step S134, is only blown out in target
When temperature TAO is regulation blowout high temperature Y1 or more, it is judged to needing HH controls.Alternatively, air conditioning control device 50 is as this
The countermeasure of the situation of sample only when set temperature Tset is regulation setting high temperature Y2 or more, is judged to needing in step S134
HH is controlled.In the case where being judged to needing HH controls, enter step S137, in the case that be determined as it is unwanted, into step
Rapid S135 and select above-mentioned usual control.
In step S137, HH controls are executed.Specifically, to the slave step S140 to S210 in this time controlling cycle

Ring stops and stops from room conditioning unit 30 to the indoor air-supply of vehicle.So, reflection is wanted to inhibit system to a certain degree
The intention of cold occupant, and also function to and make occupant notice perhaps to have carried out the effect of maloperation.That is, occupant can be made to pay attention to
It is maloperation to set temperature Tset is reduced.
In addition, as shown in figure 12, in the case where power down switch 601 is to connect, air conditioning control device 50 can also be identical
Ground decision systems disconnect.So, reflection is wanted to inhibit the intention of the occupant of refrigeration to a certain degree, and Vehicular air-conditioning fills
The consumption electric power for setting 1 is reduced.Useless power consumption caused by work therefore, it is possible to inhibit to deviate the intention of occupant, therefore
The endurance distance of vehicle is inhibited to decline.
In addition, as shown in figure 12, in the case where power down switch 601 is to connect, air conditioning control device 50 can also determine
The stopping of compressor 11.If determining in this way, in following step S230, refrigerant in refrigerating circulatory device 10 follows
Ring stops.Therefore, not by indoor evaporator 19 to from room conditioning unit 30 to the sky of the indoor foot's blow-off outlet blowout of vehicle
Gas is heated.So, reflection is wanted to inhibit the intention of the occupant of refrigeration, and air conditioner for vehicles 1 to a certain degree
Consumption electric power reduce.Useless power consumption caused by work therefore, it is possible to inhibit to deviate the intention of occupant, therefore inhibit
The endurance distance of vehicle declines.
In addition, as shown in figure 11, in the case where power down switch 601 is to connect, air conditioning control device 50 can also determine
To make blower level be less than the value in a upper controlling cycle.If determining in this way, in following step S230, centrifugation
The rotating speed of fan 33a declines.Therefore, under the air quantity of the cold wind blown out from room conditioning unit 30 to the indoor foot's blow-off outlet of vehicle
Drop.So, reflection is wanted to inhibit the intention of the occupant of refrigeration, and the consumption electricity of air conditioner for vehicles 1 to a certain degree
Power is reduced.Useless power consumption caused by work therefore, it is possible to inhibit to deviate the intention of occupant, therefore inhibit vehicle
Endurance distance declines.
In addition, as shown in figure 11, in the case where it is to connect to feel switch 602, air conditioning control device 50 can also determine
To make blower level be less than the value in a upper controlling cycle.So, reflection is wanted to inhibit multiplying for refrigeration to a certain degree
The intention of member, and improve the feeling of occupant.
In addition, as shown in figure 12, in the case where it is to connect to feel switch 602, air conditioning control device 50 can also determine
By suction inlet pattern from interior gas pattern switching be gas pattern in outer gas pattern or half.If determining in this way, in following step
In S230, the outer gas of high temperature is imported into room conditioning unit 30.Therefore, if the work of close compressor 11 at this time, from room
Interior air-conditioning unit 30 rises to a certain degree to the temperature for the air that the indoor foot's blow-off outlet of vehicle is blown out.So, certain journey
Degree reflection is wanted to inhibit the intention of the occupant of refrigeration, and improves the feeling of occupant.
In addition, as shown in figure 12, in the case where it is to connect to feel switch 602, air conditioning control device 50 can also be by A/M

, air quantity ratio (that is, warm wind ratio) by the air quantity of indoor condenser 12 relative to the air quantity around indoor condenser 12
Increase.As the state other than maximum refrigerating state, there are maximum heating state and above-mentioned intermediate state.
If determining in this way, in following step S230, the whole in wind pushing air in room conditioning unit 30
Or a part is blown out by indoor condenser 12 into car room.Therefore, it is blown from room conditioning unit 30 to the indoor foot of vehicle
The temperature for exporting the air of blowout rises to a certain degree.So, reflection is wanted to inhibit the meaning of the occupant of refrigeration to a certain degree
Figure, and improve the feeling of occupant.
In addition, as shown in figure 12, in the case where it is to connect to feel switch 602, air conditioning control device 50 can also determine
Ptc heater 24 is set to work.If determining in this way, in following step S230, ptc heater 24 is energized and starts to send out
Heat.Therefore, the temperature of the air blown out from room conditioning unit 30 to the indoor foot's blow-off outlet of vehicle rises to a certain degree.In this way
One, reflection is wanted to inhibit the intention of the occupant of refrigeration to a certain degree, and improves the feeling of occupant.In addition, airconditioning control fills
50 are set in the case where being determined as that ptc heater 24 is made to work, can also concurrently determine air mixing aperture from maximum
Refrigerating state is switched to other than maximum refrigerating state (such as maximum heating).
In addition, air conditioning control device 50 may correspond to pay attention to switch 600, power down switch 601, feel switch 602
The various combinations of on-off and above-mentioned processing is combined.For example, it may be paying attention to switch 600 and power down switch

(summary)
According to the first viewpoint shown in part or all of the respective embodiments described above, set temperature is less than the amount of a reference value
Bigger, then usual control unit more increases air conditioner for vehicles to the indoor draft capacity of vehicle.In addition, usually control unit is based on vehicle
The temperature of outdoor air is less than heating threshold value is forced, regardless of how set temperature all selects heating mode.In addition, in car room
The temperature of outer air is special if set temperature declines less than when forcing the heating threshold value and usual control unit to have selected heating mode
Other control unit controls air conditioner for vehicles, so that the indoor heating effect of vehicle reduces.
In addition, according to the second viewpoint, the temperature of the air outside car room is less than pressure heating threshold value and the choosing of usual control unit
When having selected heating mode, if set temperature declines, target blowout temperature of the special control unit based on air conditioner for vehicles is less than
The case where regulation blowout low temperature, and air conditioner for vehicles is controlled, so that the indoor heating effect of vehicle reduces.
The set temperature the low, and lower target blowout temperature is the known fact.Therefore, it is less than based on target blowout temperature
Regulation blows out low temperature and especially control unit reduces heating effect, thus enables that the special control unit model substantially low in set temperature
