Description

Embodiments of the present invention relate to air conditioning control devices, air conditioning control methods and computer programs.

Of the energy consumed by building equipment such as office buildings, air-conditioning-related energy accounts for about 40%. Therefore, energy saving related to air conditioning contributes to energy saving of building equipment. Various air conditioning control devices have been proposed from the viewpoint of energy saving. One of the proposed air conditioning control devices is an air conditioning control device related to radiant air conditioning. Radiant air conditioning is an air conditioner that circulates cold water or hot water through a panel in the ceiling and controls the air conditioning by the effect of radiation instead of wind. Radiant air conditioning can keep the room at a uniform temperature compared to air conditioners that supply air with a fan. Radiant air conditioning controls the temperature inside the room by natural convection. Therefore, the radiant air conditioner can suppress the energy load as compared with the air conditioner that supplies air with a fan. However, since radiant air conditioning does not take in outside air, an air conditioner that takes in outside air (hereinafter referred to as an external air conditioner) is required in the living room in addition to radiant air conditioning. In order to promote energy saving related to air conditioning, it was sometimes necessary to control the entire air conditioning control system including radiant air conditioning, an external air conditioner and a heat source machine.

Alternatively, a known energy consumption minimization algorithm may be used. In this way, the load distribution determination unit 110 satisfies the PMV range and minimizes the energy consumption of the entire air conditioning control system.

The state information acquisition unit 107 records the acquired state information in the state information storage unit 104 (step S104). The control unit 106 determines whether or not to update the model recorded in the model storage unit 105 (step S105). For example, the control unit 106 may update the model at a predetermined date and time, or may update the model when receiving an instruction to update the model via the input unit 102. The model may be updated when the model is not recorded. When the control unit 106 determines that the model is to be updated (step S105: YES), the process transitions to step S106. When the control unit 106 determines that the model is not updated (step S105: NO), the process proceeds to step S108.

The load distribution determination unit 110 determines the set value so that the air conditioning control system operated by the determined set value satisfies the range of the comfort index and the energy consumption is minimized. The set value transmission unit 111 transmits the determined set value to the first heat source machine control device 200, the external air conditioner control device 300, the second heat source machine control device 400, and the radiant air conditioning control device 500 (step S109).

The air conditioning control device 100 configured in this way can minimize the energy consumption of the entire air conditioning control system 1 including the radiant air conditioning system 403 so as to satisfy the comfort index received from the user. By using the models of the external air conditioner 203 and the radiant air conditioning 403, the load distribution determining unit 110 of the air conditioning control device 100 uses the air conditioning control system 1 according to the outside air temperature, the outside air humidity, the room temperature, the room humidity, the room load, and the like. Determine a setting that minimizes overall energy consumption. Then, the set value transmission unit 111 of the air conditioning control device 100 sets the determined set value to each control device (for example, the first heat source device control device) to set the air conditioning related set value such as the external air conditioner supply air temperature and the radiated air conditioning room temperature. 200, external conditioner control device 300, second heat source unit control device 400, and radiation air conditioning control device 500). By operating each control device based on the transmitted set value, it is possible to minimize the energy consumption of the entire air conditioning control system 1 while satisfying the comfort index received from the user.
Further, the model estimation unit 109 of the air conditioning control device 100 may temporarily install a sensor such as a radiation thermometer to estimate the model of the radiant air conditioning 403. With this configuration, the load distribution determination unit 110 can estimate the radiant temperature using the model even after the radiation thermometer is removed. This eliminates the need for a permanent radiation thermometer.

The set value is a value representing the load distribution of the external air conditioner 203 and the radiant air conditioner 403 so as to satisfy the comfort index and reduce the energy consumption of the external air conditioner 203 and the radiant air conditioner 403.

In the present embodiment, the energy consumption of the air conditioning control system is expressed by the following mathematical formula (10).

Energy consumption of the entire air conditioning control system (Eall) = External controller fan electric energy (E_fan) + 1st heat source machine cooling electric energy (E1_hs) + 1st heat source machine pump electric energy (E1_pump) + Well water pump electric energy (Ew_pump) (10)

FIG. 5 is a flowchart showing a flow of processing for determining the set value of the second embodiment. The comfort index acquisition unit 108 receives the comfort index of the living room 10 via the input unit 102 (step S101). The control unit 106 records a predetermined model in the model storage unit 105 (step S102a). The predetermined model is, for example, the electric energy of the external controller fan (E_fan), the electric energy of the first heat source machine (E1_hs), and the pump power of the first heat source machine represented by the formulas (1) to (3) and (9). This is a model in which each value of quantity (E1_pump) and well water pump electric energy (Ew_pump) is calculated.

The state information acquisition unit 107 acquires state information such as outside air temperature, outside air humidity, indoor temperature, indoor humidity, indoor load, and well water temperature (step S103a). The state information acquisition unit 107 records the acquired state information in the state information storage unit 104 (step S104). The control unit 106 determines whether or not to update the model recorded in the model storage unit 105 (step S105). For example, the control unit 106 may update the model at a predetermined date and time, or may update the model when receiving an instruction to update the model via the input unit 102. The model may be updated when the model is not recorded. When the control unit 106 determines that the model is to be updated (step S105: YES), the process transitions to step S106. When the control unit 106 determines that the model is not updated (step S105: NO), the process proceeds to step S108.

The model estimation unit 109 estimates a model of the amount of cooling heat and the radiant temperature in the radiant air conditioning 403 (step S106). The model estimation unit 109 records the estimated model in the model storage unit 105 (step S107).

The load distribution determination unit 110 determines the set values for the first heat source unit control device 200, the external air conditioner control device 300, and the radiant air conditioning control device 500 (step S108a). The load distribution determination unit 110 determines the first chilled water temperature set value, the external air conditioner supply air temperature set value, and the room temperature set value as set values. The load distribution determination unit 110 determines the set value so that the air conditioning control system operated by the determined set value satisfies the range of the comfort index and the energy consumption is minimized. The set value transmission unit 111 transmits the determined set value to the first heat source machine control device 200, the external air conditioner control device 300, the second heat source machine control device 400, and the radiant air conditioning control device 500 (step S109).

The air conditioning control device 100a configured in this way can minimize the energy consumption of the entire air conditioning control system 1 including the radiant air conditioning 403 so as to satisfy the comfort index received from the user. The radiant air conditioning 403 of the air conditioning controller 100a uses well water as unused heat energy in the radiant air conditioning. Therefore, the air conditioning control system 2 can reduce the overall energy consumption. In the second embodiment, well water is used as unused heat energy, but the method is not limited to well water. For example, the air conditioning control device 100a may use a liquid obtained from river water or the like as unused heat energy. Further, the air conditioning control device 100a may use the exhaust heat generated by the cogeneration system or the air conditioning control system 2 and the cold water generated by using a rechargeable refrigerator or the like. Further, the air conditioning control device 100a may use hot water generated as exhaust heat of the cogeneration system or the fuel cell for the radiant air conditioning 403 during heating.

(Third Embodiment)
FIG. 6 is a functional block diagram showing a functional configuration of the air conditioning control device 100b according to the third embodiment. The air conditioning control device 100b corrects the set value related to humidity according to the indoor humidity. Since the radiant air conditioner 403 removes the sensible heat load, the humidity in the room cannot be controlled. Therefore, in the air conditioning control system 1, it is necessary to control the humidity in the room by using the external air conditioner 203. In an air conditioning control system, increasing dehumidification generally requires a lot of energy, so it does not save energy. The air conditioning control device 100b of the third embodiment realizes both energy saving and comfort of the entire air conditioning control system including the radiant air conditioning 403. The air conditioning control device 100b includes a control unit 106b instead of the control unit 106. The air conditioning control device 100b is the same as the air conditioning control device 100 in the first embodiment in other respects. Hereinafter, the points different from the first embodiment will be described.

The air conditioning control device 100b is configured by using an information processing device such as a personal computer or a server. The air conditioning control device 100b includes a CPU, a memory, an auxiliary storage device, and the like connected by a bus, and by executing an air conditioning control program, the communication unit 101, the input unit 102, the display unit 103, the state information storage unit 104, and the model storage. It functions as a device including a unit 105 and a control unit 106b. All or part of each function of the communication unit 101, the input unit 102, the display unit 103, the state information storage unit 104, the model storage unit 105, and the control unit 106b uses hardware such as an ASIC, PLD, or FPGA. It may be realized. The air conditioning control program may be recorded on a computer-readable recording medium. The computer-readable recording medium is, for example, a flexible disk, a magneto-optical disk, a portable medium such as a ROM or a CD-ROM, or a storage device such as a hard disk built in a computer system. The air conditioning control program may be transmitted via a telecommunication line.

The control unit 106b controls the operation of each unit of the air conditioning control device 100b. The control unit 106b is executed by a device including a processor such as a CPU and a RAM. By executing the air conditioning control program, the control unit 106b serves as a state information acquisition unit 107, a comfort index acquisition unit 108, a model estimation unit 109, a load distribution determination unit 110b, a set value transmission unit 111b, and a set value correction unit 112. Function.

The load distribution determination unit 110b is not only set values for the first heat source machine control device 200, the external air conditioner control device 300, the second heat source machine control device 400, and the radiation air conditioning control device 500, but also outside the humidity control in the living room 10. Determine the air conditioning dew point temperature setting value. The external air conditioner supply air dew point temperature set value represents the temperature at which the air supplied by the external air conditioner 203 condenses. The external air conditioner supply air dew point temperature set value may be specified in advance as a constant value, or may be set according to a combination of air temperature and humidity. The external air conditioner supply air dew point temperature set value may be acquired from the outside via the communication unit 101, or may be recorded in the air conditioning control device 100b.

The set value correction unit 112 corrects the external air conditioner supply air dew point temperature set value determined by the load distribution determination unit 110b based on the indoor humidity acquired by the state information acquisition unit 107, and corrects the external air conditioner supply. Determine the dew point temperature setting value. The set value correction unit 112 determines the corrected external air conditioner supply air dew point temperature set value according to the acquired indoor humidity value. Specifically, the set value correction unit 112 corrects the external air conditioner supply air dew point temperature set value based on the following rules.

The case where the dew point temperature set value of the external controller is not corrected in the previous calculation will be described. The pre-correction external air conditioner supply air dew point temperature set value represents the external air conditioner supply air dew point temperature set value before being corrected in the previous calculation. When the indoor humidity is higher than 70%, the set value correction unit 112 sets a value obtained by subtracting 1 from the pre-correction external air conditioner supply air dew point temperature set value as the corrected external air conditioner supply air dew point temperature set value. When the indoor humidity is smaller than 40%, the set value correction unit 112 sets the value obtained by adding 1 from the pre-correction external air conditioner supply air dew point temperature set value as the corrected external air conditioner supply air dew point temperature set value. When the indoor humidity is 40% or more and 70% or less, the set value correction unit 112 uses the pre-correction external air conditioner supply air dew point temperature set value as it is as the corrected external air conditioner supply air dew point temperature set value.

The case where the dew point temperature set value of the external controller is corrected in the previous calculation will be described. The current external air conditioner supply air dew point temperature set value represents the external air conditioner supply air dew point temperature set value determined by the load distribution determination unit 110b. When the indoor humidity is higher than 70%, the set value correction unit 112 sets a value obtained by subtracting 1 from the current external air conditioner supply air dew point temperature set value as the corrected external air conditioner supply air dew point temperature set value. When the indoor humidity is smaller than 40%, the set value correction unit 112 sets a value obtained by adding 1 from the current external air conditioner supply air dew point temperature set value as the corrected external air conditioner supply air dew point temperature set value. When the indoor humidity is 40% or more and 70% or less, the set value correction unit 112 uses the current external air conditioner supply air dew point temperature set value as it is as the corrected external air conditioner supply air dew point temperature set value.

The set value correction unit 112 may correct the dew point temperature set value of the external controller for each control cycle of the air conditioning control device 100b, or may carry out the correction at a cycle longer or shorter than the control cycle of the air conditioning control device 100b. May be good. For example, when the control cycle of the air conditioning control device 100b is 1 hour and the set value correction unit 112 corrects the dew point temperature set value of the external controller for each control cycle, the indoor humidity increases by 70% because the control cycle is long. Beyond that, it can significantly reduce comfort. Further, when the control cycle of the air conditioning control device 100b is 1 minute and the set value correction unit 112 corrects the dew point temperature set value of the external controller for each control cycle, it takes several minutes or more to change the indoor humidity. , External air conditioner supply air dew point temperature drops significantly, which may result in excessive dehumidification. Therefore, the correction of the dew point temperature set value of the external controller by the set value correction unit 112 does not necessarily have to coincide with the control cycle of the air conditioning control device.

The set value transmission unit 111b transmits the determined first chilled water temperature set value to the first heat source unit control device 200. The set value transmission unit 111b transmits the determined external air conditioner supply air temperature set value and the corrected external air conditioner supply air dew point temperature setting to the external air conditioner control device 300. The set value transmission unit 111b transmits the determined second chilled water temperature set value to the second heat source unit control device 400. The set value transmission unit 111b transmits the determined indoor temperature set value to the radiant air conditioning controller 500.

FIG. 7 is a flowchart showing a flow of processing for determining the set value of the third embodiment. Since steps S101 to S107 of the flowchart shown in FIG. 7 are the same as those in the first embodiment, the description thereof will be omitted.

The load distribution determination unit 110b sets the set value and the air conditioner supply air dew point temperature set to be transmitted to the first heat source machine control device 200, the external air conditioner control device 300, the second heat source machine control device 400, and the radiant air conditioning control device 500. The value is determined (step S108b). The set value correction unit 112 corrects the external air conditioner supply air dew point temperature set value determined by the load distribution determination unit 110b based on the indoor humidity acquired by the state information acquisition unit 107, and corrects the external air conditioner supply. The air dew point temperature set value is determined (step S201). The set value transmission unit 111b transmits the determined set value to the first heat source machine control device 200, the external air conditioner control device 300, the second heat source machine control device 400, and the radiant air conditioning control device 500. The set value transmission unit 111b transmits the corrected external air conditioner supply air dew point temperature set value to the external air conditioner control device 300 (step S109b).

The air conditioning control device 100b configured in this way can minimize the energy consumption of the entire air conditioning control system 1 including the radiant air conditioning system 403 so as to satisfy the comfort index received from the user as in the first embodiment. Further, when the indoor humidity becomes large or small due to a sudden change in the living room environment or an error of the model related to each control device, the set value correction unit 112 of the air conditioning control device 100b has an external air conditioner supply air dew point according to the indoor humidity. Correct the temperature setting value. The corrected external air conditioner supply air dew point temperature setting can prevent a significant deterioration of the living room environment. In the third embodiment, the set value correction unit 112 corrects the external air conditioner supply air dew point temperature set value. However, the set value correction unit 112 may correct the indoor humidity set value. In this case, the load distribution determination unit 110b determines the indoor humidity set value. That is, the set value corrected by the set value correction unit 112 may be any one related to the indoor humidity.

(Modified example of the third embodiment)
The set value correction unit 112 of the third embodiment corrects the external air conditioner supply air dew point temperature by +1 degree or -1 degree each time the set value is corrected. However, the set value correction unit 112 may be configured to correct the external air conditioner supply air dew point temperature using, for example, a table as shown in FIG. The table shown in FIG. 8 is entered, for example, by the user of the air conditioning controller 100b. The set value correction unit 112 can perform detailed set value correction intended by the user by generating a correction temperature function based on the table.

The offline state means, for example, a state in which communication with the load distribution determination unit 110c is impossible. The offline processing device 120 includes a CPU, a memory, an auxiliary storage device, and the like connected by a bus, and functions as a device including a communication unit 121, a model storage unit 122, and a control unit 123 by executing an air conditioning control program.
