BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat storage cooling / heating control method in which a heat storage material cooled or heated by a heat source device is supplied to a heat exchange load for cooling or heating and used for cooling or heating.

[0002]

2. Description of the Related Art FIG. 6 is a block diagram showing a conventional heat storage cooling and heating apparatus disclosed in, for example, Japanese Patent Application Laid-Open No. 2-103318, in which 21 is a heat source device, 22 is a heat storage tank, and 23 is a heat storage tank.

2 is the heat storage utilization side pipe, and this pipe 29 is the heat storage tank 22,
The load 26 and the heat exchanger 25 are connected as shown.

Further, 30 is a heat medium pump provided in the pipe 27, 31 is a cold / hot water pump provided in the pipe 29, 32 is a three-way switching valve provided in the pipe 27 on the heat output side of the heat source device 21, 3
Reference numeral 3 denotes a three-way switching valve provided in the pipe 29 on the heat storage utilization side of the heat storage tank 22, which functions as means for controlling the amount of heat storage used.

Reference numeral 34 denotes a temperature sensor provided in the heat storage tank 22, and 3
5 is a flow meter for measuring the amount of heat storage in the heat storage tank 22, 36
Are temperature difference sensors that measure the temperature difference between the inlet and outlet of the heat storage utilization side pipe of the heat storage tank 22, and these function as means for detecting the amount of heat storage used.

Reference numeral 37 is a control device for controlling the amount of heat storage used, and this control device 37 has means for preliminarily inputting and storing a heat storage use pattern to be a reference, that is, a storage device.

Next, the operation will be described. Cold heat or warm heat, which is the heat output of the heat source device 21 such as a refrigerator or a heat pump, is transferred by the heat medium pump 30 to the heat output of the heat medium pipe 2.
7. By circulating through the heat storage tank 22, the heat is transferred from the heat exchanger tube 23 provided inside the heat storage tank 22 to the heat storage body 24, and the heat is stored therein.

The stored cold or hot heat is transmitted to the load 26 by circulating the cold or hot water through the heat storage tank 22, the pipe 29, the load 26, and the heat exchanger 25 by the cold / hot water pump 31.

[0011]

Since the conventional heat storage cooling / heating device is configured as described above, the control device 37 uses the heat storage according to the heat storage use pattern regardless of the load of the day. Since it is controlled, if the days are small enough that the load falls below the heat storage amount, the remaining heat storage amount that has not been used up will accumulate, so in order to eliminate this, heat storage operation at night is performed every certain number of days. There was a problem that it was not economical because it was necessary to set a day when it was not done, and cheap electricity at night could not be effectively used.

Further, since this device requires the flowmeter 35 and the differential temperature sensor 36, the cost of the device becomes high, and when this control method is applied to the existing heat storage cooling / heating device, it is not large. There were problems such as the need for construction.

The invention of claim 1 has been made to solve the above-mentioned problems, and each day, during the heat storage time, the remaining heat storage amount at the heat storage start time of the day and the load of the previous day are measured and stored, respectively. By predicting the load of the day from the load of the reference day and planning the operating time of the heat source device 21 on the day corresponding to this, appropriate heat storage and its use according to the load can be performed, and at night, it is inexpensive. An object of the present invention is to obtain a heat storage cooling / heating control method that can effectively use electric power.

According to the second aspect of the present invention, the operation history of the heat source device is stored every day, the load on the day is predicted from the load on the reference day,
By planning the operation time of the heat source equipment on the day corresponding to this, it is possible to obtain a heat storage cooling and heating control method that can appropriately store heat according to the load and use it, and can effectively use inexpensive electricity at night And

[0015]

According to a first aspect of the present invention, there is provided a heat storage cooling / heating method, wherein a temperature sensor provided in a heat storage tank determines whether or not the temperature of a heat storage material reaches a heat storage reference temperature. A second step of obtaining the residual heat storage amount at the heat storage start time of the day from one step, the operation reference time of the heat source device required to store heat to the position of the temperature sensor, and the elapsed time from the start of the heat storage operation; The third step of detecting the load equivalent time corresponding to the load of the previous day from the residual heat amount obtained in the two steps and the operating time of the heat source device of the previous day, and predicting the load equivalent time of the current day from the load equivalent time of the reference day, and ,
The time obtained by subtracting the residual heat storage amount at the start of operation of the heat source device on the day from the load equivalent time predicted in the third step,
The fourth step, which is the operation planning time of the heat source equipment on the day, is executed, and in the fifth step, priority is given to the operation time zone of the heat source equipment preset corresponding to the operation planning time set in the fourth step. The operation of the heat source device is controlled to be continued or stopped according to the order.

In the heat storage cooling and heating method according to the invention of claim 2, there is provided a sixth step of predicting a load equivalent time of the current day from the actual operation time of the reference day, and a load equivalent time predicted in the sixth step. The seventh step of comparing the time required to fully store heat in the heat storage tank and the result of the comparison in the seventh step, when the load equivalent time is longer than or equal to the time required to store the heat, The eighth step of operating the heat source device until the heat storage tank is full, and the difference between the load equivalent time and the time required to store the heat when the heat storage tank is full and the heat storage utilization time is reached in the eighth step. Is necessary for accumulating the load-equivalent time in the ninth step, the tenth step of operating the heat source device until the planned time runs out, and the seventh step. When a short with respect to that time, performed the eleventh step of the operation plan by the load corresponding time, first
In the second step, the heat source device is stopped depending on whether the planned time planned in the eleventh step is exhausted, the heat storage tank is full, or the heat storage utilization time is reached.

[0017]

In the heat storage cooling and heating control method according to the invention of claim 1, the time obtained by subtracting the residual heat storage amount at the start of operation of the heat source device of the day from the load equivalent time of the day is set as the operation planned time of the heat source device of the day, At the end of the heat source device operation on the day, the residual heat amount is set to 0, and the residual heat amount is not accumulated.

In the heat storage cooling / heating control method according to the second aspect of the present invention, the load equivalent time of the day is compared with the heat storage full reference time, and when the load equivalent time is larger than the heat storage full reference time, the heat storage tank becomes full at night. The effective heat storage is performed at night, and during the daytime air conditioning operation, the heat storage equipment shortage is compensated by the heat source equipment operation corresponding to the above time difference during the daytime, while the load equivalent time When the time is less than the full reference time, the vehicle is operated at night for a load-equivalent time and the daytime operation is stopped to prevent energy loss during the daytime.

【Example】

Example 1. An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 3 is a heat storage tank, which is filled with a heat storage material 10 such as water. Reference numeral 1 denotes a heat source device such as a heat pump, from which hot or cold heat is supplied to the heat storage tank 3 by the primary pump 4 and the primary pipe 8.

At this time, the heat storage material 1 supplied to the heat source device 1
The three-way valve 6 mixes the low-temperature heat storage material 10 and the high-temperature heat storage material 10 in the heat storage tank 3 so that the temperature of 0 becomes constant.

Further, the heat storage tank 3 includes secondary pumps 5 and 2
It is connected to a load 2 such as an air conditioner via a secondary pipe 9, and outputs cold heat or warm heat consumed by this load 2.

Further, a temperature sensor 7 is installed in the heat storage tank 3.
Individually installed, the measured temperature is control device 11
It is designed to be supplied to the residual heat amount measuring unit inside. Also, in the heat storage operation of the heat source device 1, the heat storage reference time X required to store heat from the left end of the heat storage tank 3 to the position of the temperature sensor 7.
Are stored in the storage unit in the control device 11.

Next, the operation will be described. Here, 2
An example will be described in the case of summer cooling in which one day is from 2:00 to 22:00 on the next day. In this case, the night heat storage operation time is from 22:00
At 8:00 (10 hours), the daytime heat storage utilization time zone is from 8:00 to 22.
As the time (14 hours), the control operation will be described based on the flowchart of FIG.

First, when the control device 11 starts control by a start command (step ST51), it determines whether or not the heat storage start time is 22:00 (step ST52). Two
If it's not two o'clock, wait there.

Then, at 22:00, the stored 1
The data for the day is shifted to the previous day, that is, the current day is shifted to the previous day, the previous day is shifted to the day before two, and the current day is cleared to zero (step ST53).

Next, the heat source device 1 is caused to start a heat storage operation (step ST54), and subsequently, it is determined whether or not the temperature sensor 7 has detected the heat storage reference temperature (for example, 7 ° C.), that is, the temperature of the heat storage material 10 is the heat storage. It is determined whether or not the reference temperature is reached (first step) (step ST55). In this way, if the temperature sensor 7 detects heat storage, the operation of the heat storage device starts 2
From the elapsed time W from 2 o'clock and the heat storage reference time X, the residual heat storage amount Zs at the heat storage start time of the day is obtained by the calculation of Zs = X−W. Here, the residual heat storage amount is the amount of water stored at the end of air conditioning on one day.

At the same time, the residual heat quantity Z1e at the air-conditioning end time on the previous day is calculated as Z1e = Zs and stored in a predetermined memory (second step) (step ST5).
6). Next, similarly obtained, the remaining heat amount Zis at the start of operation of the reference date stored in the predetermined memory of the control device 11, the remaining heat amount Zie at the end of the air conditioning, and the operation record of the heat source device 1 Load equivalent time xa of the day from time Yi
Is predicted as xa = (Yi + Zis−Zie) × P (third step) (step ST57). Here, the load equivalent time is the operating time of the heat source device 1 corresponding to the air conditioning load of one day.

Here, P is a coefficient determined by the operation mode of the day, for example, if P = 1 on weekdays, 0.2 on holidays, 0.7 on half days, 1.2 on holidays, and so on. , Preset.

The reference date is a day assumed to have the same load pattern as the current day. For example, when the current day is the same operation mode as the previous day, the previous day is set as the reference day and the current day is a different operation mode from the previous day. In this case, the weekday that is closest to the current day shall be the reference date.

Next, the operation plan time xb of the day is xb =
xa-Zs is calculated and obtained (fourth step) (step ST58). If it is determined in step ST55 that the temperature sensor 7 has not yet detected the heat storage temperature, this is repeated until 8 o'clock. Here, the planned operation time is the operation time of the heat source device for one day, and is set to the time when the remaining heat storage amount is expected to be 0 when the air conditioning ends. That is, the heat storage operation is continued (step S
T59).

If the temperature sensor 7 does not detect the heat storage reference temperature of 7 ° C. even at 8 o'clock, it is considered that the heat storage reference temperature has been detected at 8 o'clock because the nighttime heat storage time zone has ended, that is, , W = 10 hours (step ST
60), the process returns to step ST56 and the same calculation as above is performed (steps ST56 to 58).

Next, the planned remaining time Δxb is calculated from Δxb = xb-Y based on the planned operation time xb and the actual time Y from 22:00 that has been operated up to then (step ST61), and Δ
If xb ≦ 0, the operation of the heat source device 1 is stopped (fifth step) (step ST62), and the process returns to the start. On the other hand, if Δxb> 0, the operation is continued for Δxb according to the preset priority order of the heat source device operating time zone (fifth step) (step ST63).

Here, the preset priority order of the operation time zones of the heat source device 1 is, for example, the first priority is the nighttime heat storage time zone until 8:00, the second priority is from 8:00 to the peak cut start time, The third priority is the peak cut end time to 22
Decide by time.

In these time zones, if the operation is carried out by Δxb, the operation returns to the start and prepares for the control of the next day. The heat storage reference time X detected by the temperature sensor 7 in the heat storage tank 3 may be about 3 to 5 hours.

Example 2. In the above embodiment, if the temperature sensor 7 does not detect the heat storage reference temperature even at 8 o'clock,
Sometimes it is assumed that the heat storage reference temperature is detected, that is,
Although the case where W = 10 hours and the process returns to step ST56 is shown, as shown in FIG. 3, step ST55 may be repeated until 22:00 on the next day (step ST6).
4) Only by the heat source device operating during the daytime heat storage utilization time period, the same effect as the above embodiment can be obtained.

Example 3. FIG. 4 shows another embodiment of the present invention. In the figure, 3 is a heat storage tank, which is filled with a heat storage material 10 such as water. Reference numeral 1 denotes a heat source device such as a heat pump, from which hot or cold heat is supplied to the heat storage tank 3 by the primary pump 4 and the primary pipe 8.

At this time, the heat storage material 1 supplied to the heat source device 1
The three-way valve 6 mixes the low-temperature heat storage material 10 and the high-temperature heat storage material 10 in the heat storage tank 3 so that the temperature of 0 becomes constant.

The heat storage tank 3 is composed of the secondary pumps 5 and 2
It is connected to a load 2 such as an air conditioner via a secondary pipe 9, and outputs cold heat or warm heat consumed by this load 2.

Reference numeral 15 is a heat storage full detection sensor mounted in the inlet pipe of the heat source device 1, and its output is supplied to the heat storage full detection unit in the control device 11. In the heat storage operation of the heat source device 1, the time TW required for the heat storage tank 3 to fully store heat from the left end to the right end of the heat storage tank 3 is stored in the storage unit in the control device 11.

Next, the operation will be described. Here, 2
An example will be described in the case of summer cooling in which one day is from 2:00 to 22:00. In this case, the night heat storage operation time period is from 22:00 to 8 o'clock (10 hours), and the daytime heat storage use time period is from 8 o'clock to 22:00 (14 hours), and the control operation will be described with reference to the flowchart of FIG.

First, when the control device 11 starts control by a start command (step ST71), it determines whether or not it is 22:00 which is the heat storage start time (step ST72). Two
If it's not two o'clock, wait there. On the other hand, at 22:00, the stored data for one day is shifted to the previous day, that is, the current day's data is shifted to the previous day's data, and the previous day's data is shifted to the previous two days,
At the same time, the current day is cleared to zero (step ST7).
3).

Next, the heat source device 1 starts to store heat (step ST74). Further, the load equivalent time xa of the current day is predicted as xa = Yi × P from the actual operation time Yi of the reference day (sixth step) (step ST75). Here, P is a coefficient determined by the operation mode of the day,
For example, assuming that P = 1 on weekdays, 0.2 is set for holidays, 0.7 is set for half days, and 1.2 is set for holidays.

Further, the visit day is a day which is assumed to have the same load pattern as the current day. For example, when the current day is the same operation mode as the previous day, the previous day is set as the reference day, and the current day is set in a different operation mode from the previous day. In some cases, the reference day is the weekday that is closest to the current day.

Next, the load equivalent time xa of the day is compared with the time TW required to fully store heat in the entire heat storage tank (seventh step) (step ST76).

If xa ≧ TW as a result of this comparison, it is determined that the load on the day is equal to or more than the heat storage tank is full, and the heat source device 1 is operated until the heat storage tank is full (eighth step) (step ST77). Then, when the heat storage full detection sensor 15 detects that the heat storage tank is full (for example, when it becomes 7 ° C. or less), it is determined whether it is 8:00 (step ST7).
8).

Here, if it is determined that it is before 8 o'clock, the load is not applied yet because it is not in the daytime heat storage utilization time zone.
The heat source device 1 is stopped (step ST79), and the heat storage device 1 waits until a load is applied while the heat storage is full. In addition, at 8:00, the heat is used during the daytime and the load is applied, so xa-TW time is calculated as the remaining operation plan of the day (9th step) (step ST80).

What is important here is that the time TW required for heat storage is subtracted from the load equivalent time xa, not the actual time ya during the nighttime heat storage operation of the day. Therefore, although ya ≦ TW, TW−ya = Za is the residual heat storage amount, and by operating the xa−TW time operation plan during the daytime heat storage utilization time zone, the remaining heat storage amount Za is not operated during the daytime, 1 if the current day has the same load as the reference day
At the end of the day, the residual heat storage is 0.

Next, the heat source device 1 is restarted (step ST81) and operated until the planned time runs out (step ST82). When the planned time runs out, the heat source device 1 is stopped (10th step) (step ST83). ), Return to the start.

On the other hand, in step ST76, xa <
If it is TW, the operation is planned for the load equivalent time xa only in the nighttime heat storage time zone (the eleventh step) (step ST84) and the planned time runs out (step ST8).
5), whether the heat storage tank 3 is full (step ST86),
Depending on whether it is 8:00 (step ST87), the heat source device 1 is stopped (12th step) (step ST88), and the daytime operation is not performed and the process returns to the start.

Example 4. Although the heat storage full detection sensor 15 is installed in the inlet pipe of the heat source device 1 in the above-described embodiment, the heat storage full detection sensor 15 is installed in the heat storage tank 3 on the high temperature side in summer (low temperature side in winter).
The same effect as in the above embodiment can be obtained.

[0051]

As described above, according to the first aspect of the present invention, the temperature sensor provided in the heat storage tank determines whether the temperature of the heat storage material reaches the heat storage reference temperature or not. Second, the residual heat storage amount at the heat storage start time of the day is calculated from the operation reference time of the heat source device required to store heat up to the position of the temperature sensor and the elapsed time from the start of the heat storage operation.
The load equivalent time corresponding to the load of the previous day is detected from the step, the residual heat amount obtained in the second step, and the operating time of the heat source device of the previous day, and the load equivalent time of the current day is predicted from the load equivalent time of the reference day. And a fourth step in which a time obtained by subtracting the residual heat storage amount at the time of starting the operation of the heat source device from the load equivalent time predicted in the third step is set as the operation plan time of the heat source device of the day. Then, in the fifth step, the operation continuation or the stop of the heat source device is controlled according to the priority order of the operating time zone of the heat source device which is preset corresponding to the operation planned time set in the fourth step. Since it is configured to, the remaining heat quantity can be controlled to 0 at the end of air conditioning on the day by storing heat for the time corresponding to the load equivalent time on the day minus the remaining heat quantity at the start of heat storage Without those conventional manner the residual heat accumulation can be prevented from being accumulated there is an effect to be obtained.

Since inexpensive electric power can be effectively used at night, the heat storage air conditioner can be operated economically throughout the year, and only one temperature sensor needs to be installed in the heat storage tank. There is an effect that the cost can be reduced, the construction can be performed easily, and the invention can be applied to any combination of the heat source device and the heat storage tank.

According to the second aspect of the present invention, the load equivalent time of the day is predicted in advance from the actual operating time of the reference day.
Step, a seventh step of comparing the load equivalent time predicted in the sixth step with the time required to fully store heat in the heat storage tank, and the result of the comparison in the seventh step,
When the load equivalent time is longer than or equal to the time required to store the heat, an eighth step of operating the heat source device until the heat storage tank is full, and the heat storage tank is filled in the eighth step When the heat storage utilization time is reached, a ninth step of planning the time operation by obtaining a difference between the load equivalent time and the time required to store the heat, and a tenth step of operating the heat source device until the planned time runs out,
When the load equivalent time is shorter than the time required for accumulating in the seventh step, the eleventh step of operation planning for the load equivalent time is executed, and in the twelfth step, the planned time planned in the eleventh step. It is configured to stop the heat source device depending on whether the heat storage tank is full, the heat storage tank is full, or the heat storage utilization time is reached, so the load equivalent time on the day is longer than or equal to the time to fill the heat storage tank. In this case, it is possible to fill the heat storage tank with inexpensive nighttime electricity and to cope with a sudden increase in load during the daytime, and to avoid excessive operation during the daytime by the amount of residual heat of the previous day. effective.

On the other hand, when the load equivalent time is shorter than the above-mentioned full time, the heat storage cooling / heating device can be economically operated throughout the year by performing heat storage operation only at night for the load equivalent to the previous day, and the heat storage Since there is no need for a control sensor or the like in the tank, there is an effect that an inexpensive and easy-to-install product can be obtained.
