BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a duct type air conditioner employing a variable air volume control system capable of independently controlling the room temperature of each room, and more particularly to a controller for inputting a temperature schedule and the like.

Conventionally, the central air conditioning system that controls the air by distributing temperature-controlled air to each room by using an air duct is easily assembled with a humidifier or a high-performance filter, which allows the use of an outside air treatment or a heat exchanger, thereby providing high quality air conditioning. In addition, the air conditioning room has only a spout and a suction port, so that the indoor space can be effectively used, and there are also fewer problems with the heat transfer system, such as a heat pump chiller fan coil system or a package air conditioner distributed arrangement system. It has an effect, and thus is widely used for air conditioning of buildings. Among them, the variable air volume control method (hereinafter referred to as VAV method) that enables energy-saving operation can independently control the temperature of each room with a part of the load, and it is also possible to stop the air conditioning in the room not in use. In addition, it is possible to reduce the operating cost by varying the power of the blower according to the required air blowing amount and the size, and the capacity of the heat source can be designed small by considering the simultaneous use rate.

There are various types of VAV, but one method is to use a tightening VAV unit. This method detects the pressure in the duct that changes according to the degree of opening and closing of the damper, and controls the blower's capacity so that the value becomes a set value, so that when the load is low (the air temperature in the duct is constantly controlled even if the air volume is low). In addition, the power capacity of the blower is reduced while the required capacity of the heat source is reduced.

In the prior art using a fastening type VAV unit, Japanese Patent Application Publication No. 60-47497 and Figure 2, 10 (a) of the refrigeration and air conditioning manual (new edition, fourth edition, application) issued by the Japan Refrigeration Association are known. 13 is a system configuration diagram of these conventional air conditioners. In the same drawing, reference numeral 1 denotes a room where air is controlled, and here four cases are shown. (2) is an indoor unit arranged in the ceiling of the room (1), and is composed of an air filter (3), a heat exchanger (4), and a blower (5). (6) is the main duct connected to the air outlet of the indoor unit (2), (7) the four branch ducts branched according to the number of rooms in the main duct (6), (8) is the A tightening VAV unit inserted in the middle, the damper 9 is rotatably provided in the VAV unit 8, and a damper driven by a stepping motor (not shown), 10 is an end portion of the branch duct 7. A spout provided in the (11), the inlet provided in the lower part of the door of the room (1), 12 is a ceiling suction inlet provided on the ceiling surface of the corridor, (13) is a suction inlet of the ceiling inlet 12 and the indoor unit (2) Suction ducts for connecting the same, 14 is a room controller provided in each of the rooms 1, 15 is a temperature detector provided in the main duct 6, 16 is a pressure provided in the main duct 6 likewise The detector 17 denotes a heat source such as a heat pump connected to the heat exchanger 4, and 18 denotes operation control of the heat source, the blower 5, and the damper 9. It is a control device.

In the conventional air conditioner configured as described above, the opening and closing degree of the damper 9 is adjusted to an arbitrary position in accordance with the temperature difference between the set temperature set by the user and the detected current air temperature by each room controller 14. . Then, the pressure in the main duct 6 changes according to the opening and closing degree of the damper 9, and the pressure detector 16 detects this and changes the capacity of the blower 5 so as to be a preset set pressure. In addition, since the air temperature at the outlet of the heat exchanger 4 changes in accordance with the change in the airflow amount, the temperature detector 15 detects this temperature and controls the capability of the heat source unit 17 so as to be the preset air temperature. In this way, the air adjusted to a substantially constant temperature is blown into the interior of the room 1 with the air volume according to the magnitude of the indoor heat load at the blowing port 10. The air in which the air of the room 1 is adjusted flows from the suction port 11 to the ceiling suction port 12 through a space such as a corridor and returns to the indoor unit 2 via the suction duct 13.

A series of these control is energy saving by the control apparatus 18 according to the detection signals of the various detectors (not shown) in the room controller 14, the temperature detector 15, the pressure detector 16, and the heat source 17. Control is most appropriate to satisfy the comfort and comfort.

Although the conventional air conditioner is comprised as mentioned above, it is not performed very much to control operation while making both energy saving and comfort. Such a VAV type air conditioner is mainly used in offices, buildings, and the like. In this case, the operating hours are limited to daytime, and the air conditioning temperature is almost the same in each room, and the driving stops on a holiday on Saturday or Sunday. Therefore, the airflow control function by the VAV unit only increases or decreases the airflow amount depending on the magnitude of the heat load caused by the direction of the room or the number of people in the room, and keeps the temperature of each room constant. In such a system, in the centralized control room, an operation stop of an operating time zone and a holiday is programmed, and the control device 18 is given a command. Also in this case, the stop of controlling the air in the unused room can be realized by the operation of the room controller.

When the air conditioner of the VAV system is applied to a house, there are various problems different from those in the case of building air conditioning. According to the method of control, a significant energy saving can be realized. Manipulation is complicated and cumbersome at the same time. In addition, ducted central air conditioning is very commonly adopted in American homes, but the air conditioner that automatically performs VAV control is not practical. At most, the damper can be controlled manually or by a thermostat. In addition, the program timer set the system back to the set temperature according to the time zone. Here, the setback shifts the set room temperature at the time of heating a little lower at some time to save energy, and at the time of cooling, a little higher.

Such a conventional air conditioner is operated all day by air conditioning of the whole room. However, with the recent rise in energy prices, the economic burden is increasing, and the emergence of energy saving systems is required. Even in conventional systems, some energy savings can be achieved by setbacks, but significant energy savings are achieved by not performing zoning control (stopping airflow in rooms that do not require air conditioning). In addition, it is cumbersome to control or open or close the damper by manual operation, and there is a problem such as decrease in efficiency and increase in noise because the capacity control of the heat source or the blower is not linked to the change of air volume. .

As described above, a VAV type air conditioner is suitable as an energy saving system for homes, but in order to achieve a small energy saving for each room, a controller capable of inputting a temperature schedule for each room is required. The problem is that even if the temperature program is input according to the family's life pattern, the daily life is not constant according to this pattern, so it is necessary to be able to simply change the program. Of course, the initial value input is also simple. The above problems are summarized as follows.

(1) The life patterns are different on weekdays, holidays, and holidays.

(2) The daily life is not constant according to the pattern entered.

(3) Since there is frequent entry and exit into the room, the temperature difference between the inside and outside of the room should be small, and reach the desired temperature early.

(4) Significant energy saving is realized by Zoning and setback.

(5) Comfort is not greatly impaired by Zoning and setback.

(6) Simple input and change operations.

As a controller of an air conditioner for many rooms, although not a duct system, Japanese Utility Model Publication No. 60-85815 is known as a refrigerant piping system. This is a main controller that combines multiple controllers and room controllers so that the main controller can change the room temperature of the other room, but it is inferior in energy saving because it is impossible to enter the program of temperature schedule.

An object of the present invention is to provide a VAV air conditioner provided with a main controller and a room controller which can solve the above problems and are simple in operation and can be both energy-saving and comfortable.

Another object of the present invention is to provide an air conditioner capable of having a pleasant holiday even without entering a special program for a holiday or a holiday.

Another object of the present invention is to provide an air conditioner having good operability which can simultaneously control the air of the whole room with one touch.

Another object of the present invention is to provide a comfortable air conditioner that can set operating conditions independently in each room regardless of a predetermined program operation.

Another object of the present invention is to provide an energy-saving air conditioner capable of simply operating and stopping the air conditioning of the room during entering and leaving the room regardless of a predetermined program operation.

The above and other objects and novel features of the present invention will become apparent from the description and the accompanying drawings.

Brief descriptions of representative ones of the inventions disclosed in the present application are as follows.

In response to this, an arbitrary or fixed setback value is inputted at each time, and the setting room changes the setting room temperature of the room to its own. Then, whichever setting room temperature (reference temperature) is changed to the setting room temperature changing means or the temperature schedule input means, the value manipulated later is used.

The setback value input to the temperature schedule input means is automatically switched to a high room temperature during cooling and a low room temperature during heating in conjunction with the operation mode switching means. The timer means acts to modify the setback value of the weekly time zone to ash on holidays such as Saturdays and Sundays. The operation mode switching means modifies the setback value of the weekly time zone to zero if it is set on a holiday. When the mode of the operation mode is set to the mode of the whole room, the set room temperature of all rooms is set to the reference temperature inputted by the temperature schedule input means or the set room temperature inputted by the set room temperature changing means. The control function is controlled until the next time the program mode is switched, and the central and local selection means control the room temperature of the room according to the program inputted by the temperature schedule input means when it is set at the center. To a certain value (setting room temperature) until the next time it is switched to the center. To act to temporarily stop the control of the room.

In the same figure, 48 is a microcomputer and has a CPU 49, a memory 50, a pressure unit 51, an output unit 52, and a communication unit 53. 54 is connected to the input unit 51 via the A / D converter 55 as a room temperature detector, such as a dummyster. The keys 39 and 40 are connected to the input unit 51, and the temperature indicator 38 is connected to the output unit 52. The communication unit 53 is connected to the control device 18.

Next, the operation of the embodiment will be described with reference to FIG. 6 and FIG. 6 is a flowchart showing an operation procedure of the main controller 19, and FIG. 7 is an example of input of a temperature schedule during heating.

First, in the main controller 19, an operating condition is set and a temperature schedule is input. The step 56 adjusts the time according to the operation of the time key 28. This input signal is input to the CPU 42 via the input unit 45, stored in the memory 43 and displayed on the time display 27 via the output unit 46. After that, the display changes with time by the movement of the clock 44. Next, the operation mode is set by the operation of the operation mode key 22 in the step 57, and the result is displayed on the LEDs 23 to 26 via the microcomputer 41. In step 58, the room number is selected by the operation of the room key 30, and this result is displayed on the left end of the temperature indicator 29 as # 3. In step 59, input of the set room temperature (reference temperature) of the room set by step 58 is performed by operation of the key 31 and the key 32, and this result is obtained at the center of the temperature indicator 29. It is offset to the left and is displayed as " 26 ° C. " In steps 60 to 65, the setback value is set at each time (0 to 24 hours) with respect to the set room temperature inputted by step 59. The key is input using the key 36, and the value is displayed on the temperature indicator 29 graphically as shown in FIG. Each time the keys 33 to 36 are operated once, a value of one hour is inputted, and the procedure proceeds automatically to the next one hour. The value written on the surface of the key 33 to key 36 is set to 0 ° C at room temperature according to the preset setback value, and 2 ° C is to be set back a little for energy saving and health, such as during sleep. , 5 ℃ is often used to save energy due to emptying the room. In addition, when returning to the room temperature in a short time when entering the room, 15 ℃ is used to completely empty the room. (A practical off key, 15 ℃ Alternatively, the display may be " OFF '. In addition, the keyed in value is determined in step 62 in accordance with the mode of cooling or heating. Here, the cooling is automatically switched to high room temperature (step 63), and to low room temperature (step 64) when heating. This switching is automatically executed even when the operation mode is switched during the operation. When the key-in for 24 hours is finished, in step 66, the temperature schedule is stored in the memory 43 by the operation of the input key 37. The operations of the above steps 58 to 66 are repeated for all the rooms (step 67).

The above various input information is stored in the memory 43, and information necessary for the control of the heat source 17 and the like is transmitted to the control device 18 via the communication unit 47. After that, it is possible to change the operating conditions by manipulating each key as necessary, and the result is transmitted back to the controller 18.

7 is an example of a temperature schedule set in each room.

Even if it is programmed in too much detail, since a living pattern does not necessarily match, it inputs roughly, and it is good to respond by operation of the room controller 14 after that. Also in the room controller 14, the set room temperature (reference temperature) of the room is changed by the operation of the keys 39 and 40. The keyed in information is input to the CPU 49 via the input unit 51 of the microcomputer 48 and stored in the memory 50 and displayed on the temperature indicator 38 via the output unit 52. In addition, it is transmitted to the control device 18 via the communication unit 53. Then, the current room temperature is detected by the room temperature detector 54, inputted to the CPU 49 via the A / D converter 55 and the input unit 51, and stored in the memory 50 to control devices ( 18). The setting room temperature is changed in either the main controller 19 or the room controller 14, but the value of the later operated side is adopted as a new setting room temperature. In addition, the setting room temperature information in the memory 43 and the memory 50 is simultaneously changed whenever the set value is changed.

In addition, there are two methods for obtaining the setback value when the set room temperature is changed. One is to set the value of the setback (temperature difference) as it is and slide it on the change of the set room temperature. The other is to increase or decrease the setback value as much as the set room temperature is increased or decreased. Either method may be adopted as a method of not changing).

In the above indoor example, the set back value of the temperature schedule is selected from among predetermined values using the keys 33 to 36, but the key 33 and the key 34 are the temperature key and the key 35. By using the and key 36 as a time key, it is possible to input the free setback value. In this case, more detailed temperature schedule control is possible. In the above embodiment, a heat pump is used as the heat source 17, but as a heat source, in addition to this, there is a gas, a combination of a heat pump and a gas, a combination of a heat pump and an electric heater, an air conditioner, an air conditioner and a gas furnace. Combinations, combinations of enecons and electric heaters, and auxiliary equipment used in combination with a heat source include a humidifier, an air purifier, a heat exchanger, and the like. 18) may be provided.

In the control method of the damper 9, the opening and closing degree is controlled proportionally according to the temperature difference between the room temperature and the set temperature, and the damper 9 is deployed at two positions according to the temperature difference. There is a method of controlling, and either method may be adopted.

In the above embodiment, the countermeasures in case of power failure are not taken into consideration, but the rechargeable battery is connected to the microcomputer 41 of the main controller 19 to protect the temperature schedule stored in the memory 43 from power failure or EEP-. It is good to have it stored in ROM.

In addition, the HA terminal may be provided in the control device 18 so that the operation mode of the main controller 19 can be operated by telephone from the outside place.

In addition, although it is difficult to know which room the room number displays in the main controller 19, a cover plate is provided on the unused part of the main controller 19, and a table is created at the rear to allow the user to make a ballpoint pen or the like. If you fill in the room name corresponding to the room number, it is easy to understand later.

In the above embodiment, in the case of four-room air conditioning, the case where one main controller 19 and four room controllers 14 are used is described. However, one main controller (room temperature detector) is also incorporated. And three room controllers 14). In this case, the price of the entire controller becomes low.

The time indicator 27 also displays the day of the week together with the time of day. Reference numerals other than the above description indicate the same parts as those in FIG. 2.

The difference in the life patterns between weekdays, holidays, and holidays is only daytime, and the difference in nighttime is small. When a pre-set holiday (switch for Sunday, Saturday and Sunday setting is not shown) is stored in the memory 43, the program of the temperature schedule is automatically corrected as indicated by the dotted line in FIG.

The correction time zone is, for example, 6 to 18 hours, and the setback value therebetween is set to 0 ° C. This control method is inconsistent with energy saving, but it is a consideration that does not impair comfort on frequent holidays in and out of the room. The second operation mode key 76 is operated to set a holiday mode on a holiday or a special holiday that sometimes occurs in addition to the weekly holiday. By this operation, the value of the weekly setback is automatically corrected to 0 deg. This mode is automatically reset at zero.
