You may judge the possibility of receiving a request. In addition, for example, the determination unit 12a receives the power adjustment request by calling the content of the contract with the electric power company 2 stored in the storage unit 13 and referring to the date and time of the power adjustment request determined in advance in the contract content. It may be possible to determine whether or not there is a possibility.

(3) Operation of Heating Device Hereinafter, the operation of the heating device 20, in particular, the operation of the heating device 20 related to the power adjustment request will be described with a specific example. In other words, hereinafter, control of the heating device 20 by the control device 200 (aggregator 10 and controller 21), in particular, control of the heating device 20 by the control device 200 performed in association with the power adjustment request will be described.

  Here, the operation of the heating device 20 (control content by the control device 200) will be described for each time zone on the assumption that there is a heating load as shown in FIG.

  First, the heating load shown in FIG. 4 as a premise will be described. FIG. 4 shows, for example, a heating load in a double-working home. After the resident sleeps, the heating load becomes 0 from midnight to early morning (from 23:00 to 6:00 in FIG. 4). In the time zone (from 7:00 to 8:00 in FIG. 4) after getting up, the heating is not used from midnight to early morning and the room temperature is lowered, so a relatively large heating load is required. Thereafter, the heating load becomes zero again in the time period from when the resident goes to work and returns home (9:00 to 15:00 in FIG. 4). In the evening when the resident returns home (around 16:00 to 18:00 in FIG. 4), heating is not used in the daytime and the room temperature decreases, so a relatively large heating load is required. Thereafter, heating is used during the time period until the resident goes to bed (until 22:00 in FIG. 4), but the heating load gradually decreases as the time slows down.

  Here, the management device 2a requests the aggregator 10 to promote the amount of power used at midnight (1 to 3 in FIG. 4) when the amount of power demand decreases. Moreover, the management apparatus 2a requests | requires suppression of the electric power consumption with respect to the aggregator 10 in the evening (in FIG. 4, 17: 00-18: 00) when an electric power demand amount increases.

  The operation of the heating device 20 with respect to the heating load of FIG. 4 will be described below.

  First, with respect to the heating load of FIG. 4, the heating device 20 outputs the heating capacity as shown in FIG. 5 for each time zone. Since the operation of the heating device 20 differs depending on the time zone, the operation of the heating device 20 will be described by dividing it into first to seventh time zones as shown in FIG.

  First, the basic relationship between the power adjustment request and the operation of the heating device 20 will be described before the operation of the heating device 20 in each time period is described.

  When the aggregator 10 receives a power adjustment request from the management device 2a, the heating device 20 generally operates so that the aqueous medium flows through the heat storage tank 60. That is, the control device 200 operates the heating device 20 so that the aqueous medium flows in the heat storage tank 60 in principle during the adjustment request period of the power consumption received from the management device 2a.

  Specifically, the control unit 12 of the aggregator 10 realizes the first state in which the aqueous medium flows from the indoor unit 50 to the heat storage tank 60 when the aggregator 10 receives a power adjustment request that requires promotion of power consumption. Thus, a control command for the controller 21 is generated. That is, when the aggregator 10 receives a power adjustment request for requesting the promotion of power consumption, the control command generated by the control unit 12 is such that the three-way valve 61a has the aqueous medium communication pipe 81a and the aqueous medium communication pipe 62a. And the three-way valve 61b is instructed to operate the three-way valves 61a and 61b so that the three-way valve 61b connects the aqueous medium communication pipe 62b and the aqueous medium communication pipe 82a. Further, when the aggregator 10 receives a power adjustment request for requesting the promotion of power usage, the control unit 12 generates a control command that instructs the outdoor unit control unit 23b to operate the outdoor unit 30. By controlling the heating device 20 in this way, the heat of the outdoor unit 30 can be stored in the heat storage tank 60, and the power consumption of the heating device 20 can be increased.

  Moreover, the control part 12 of the aggregator 10 implement | achieves the 3rd state in which an aqueous medium flows into the thermal storage tank 60 from the heating units 40a and 40b, when the aggregator 10 is receiving the electric power adjustment request | requirement which requests | requires suppression of electric power consumption. Thus, a control command for the controller 21 is generated. That is, when the aggregator 10 receives a power adjustment request that requires suppression of power consumption, the control command generated by the control unit 12 instructs the second pump control unit 23d to operate the second pump 64. It is. In addition, when the aggregator 10 receives a power adjustment request for requesting suppression of power consumption, the control unit 12 generates a control command that instructs the outdoor unit control unit 23b to stop the outdoor unit 30. By controlling the heating device 20 in this way, the heating units 40a and 40b can be operated using the heat stored in the heat storage tank 60, and the power consumption of the heating device 20 can be suppressed. It becomes.

  On the other hand, when the aggregator 10 has not received a power adjustment request from the management device 2a, the heating device 20 generally operates so that the aqueous medium does not flow into the heat storage tank 60. That is, the control device 200 operates the heating device 20 so that the aqueous medium does not flow into the heat storage tank 60 in principle, except for the period for requesting adjustment of the power consumption received from the management device 2a.

  Specifically, when the aggregator 10 has not received a power adjustment request from the management device 2a, the controller 12 controls the controller 12 so that the second state in which the aqueous medium does not flow from the indoor unit 50 to the heat storage tank 60 is realized. A control command for 21 is generated. In addition, when the aggregator 10 has not received a power adjustment request from the management device 2a, the controller 12 controls the controller 21 so that the fourth state in which the aqueous medium does not flow from the heating units 40a and 40b to the heat storage tank 60 is realized. Generate a control command for. That is, when the aggregator 10 has not received a power adjustment request from the management device 2a, the control command generated by the control unit 12 is such that the three-way valve 61a connects the aqueous medium communication pipe 81a and the aqueous medium communication pipe 81b. The three-way valve 61a is instructed to operate the three-way valves 61a and 62a so that the three-way valve 61a connects the aqueous medium communication pipe 82a and the aqueous medium communication pipe 82b. In addition, when the aggregator 10 has not received a power adjustment request from the management device 2a, the control command generated by the control unit 12 instructs the second pump control unit 23d to stop the second pump 64. By controlling the heating device 20 in this way, it is not necessary to heat the aqueous medium in the heat storage tank 60, and it is easy to reduce the amount of power used. In addition, since the heating device 20 is controlled in this way, it is not necessary to heat the aqueous medium in the heat storage tank 60, so that the responsiveness when the heating units 40a and 40b are started up (how fast the heating units 40a and 40b are earlier). The characteristic of whether warm air begins to blow out from).

  Next, operation | movement of the heating apparatus 20 in the 1st-7th time slot | zone shown in FIG. 5 is demonstrated separately.

(3-1) First Time Zone The first time zone shown in FIG. 5 is from 1 o'clock to 3 o'clock at midnight. As shown in FIG. 4, the first time zone is a time zone in which the aggregator 10 is receiving the promotion of power usage from the management device 2a. During the first time zone, the operation command for the heating units 40a and 40b is not input to the remote controller (not shown). At this time, the control unit 12 of the aggregator 10 generates a control command so that the heating device 20 performs the following operation in the first time zone, and transmits the control command to the controller 21.

  In the heating device 20, the outdoor unit 30 operates, and the refrigerant circulates in the refrigerant circuit 35 as shown in FIG. The motor of the compressor 31 of the outdoor unit 30 is based on the control command, and the total power adjustment amount of the heating device 20 controlled by the aggregator 10 is the target adjustment amount of the power usage amount transmitted to the aggregator 10 by the management device 2a. It is operated at a rotation speed that matches. As shown in FIG. 6, the heating device 20 is in a first state in which an aqueous medium flows from the indoor unit 50 to the heat storage tank 60. In the heating device 20, the indoor unit 50 operates, and the aqueous medium circulates between the indoor unit 50 and the heat storage tank 60 as shown in FIG. In the heating device 20, the second pump 64 and the heating units 40a and 40b are stopped.

  In other words, in the first time zone, the outdoor unit control unit 23b operates the outdoor unit 30. The three-way valve control unit 23a is configured so that the three-way valve 61a connects the aqueous medium communication pipe 81a and the aqueous medium communication pipe 62a, and the three-way valve 61b connects the aqueous medium communication pipe 62b and the aqueous medium communication pipe 82a. The valves 61a and 61b are operated. The indoor unit control unit 23c operates the indoor unit 50. The second pump control unit 23d stops the second pump 64. The heating unit controller 23e stops the heating units 40a and 40b.

  In this way, by operating the heating device 20, even when the heating units 40a and 40b are stopped, it is possible to increase the power consumption of the heating device 20 and respond to the power adjustment request.

(3-2) Second Time Zone The second time zone shown in FIG. 5 is from 7:00 to 8:00. As shown in FIG. 4, the aggregator 10 has not received a power adjustment request from the management device 2a during the second time period. In the second time zone, an operation command for the heating unit 40a is input to a remote controller (not shown). At this time, the control unit 12 of the aggregator 10 generates a control command so that the heating device 20 performs the following operation in the second time zone, and transmits the control command to the controller 21.

  In the heating device 20, the outdoor unit 30 is operated, and the refrigerant is circulated in the refrigerant circuit 35 as shown in FIG. As shown in FIG. 7, the heating device 20 is in a second state in which the aqueous medium does not flow from the indoor unit 50 to the heat storage tank 60. In the heating device 20, the indoor unit 50 operates, and an aqueous medium circulates between the indoor unit 50 and the heating unit 40a as shown in FIG. In the heating device 20, the second pump 64 is stopped. In the heating device 20, the heating unit 40a is operating and the heating unit 40b is stopped.

  In other words, the outdoor unit control unit 23b operates the outdoor unit 30 in the second time zone. The rotation speed of the motor of the compressor 31 of the outdoor unit 30 is determined by the outdoor unit control unit 23b according to the operating conditions and the like. The three-way valve control unit 23a is configured so that the three-way valve 61a connects the aqueous medium communication pipe 81a and the aqueous medium communication pipe 81b, and the three-way valve 61a connects the aqueous medium communication pipe 82a and the aqueous medium communication pipe 82b.

(4) Features The demand response system 100 of this embodiment has the following features.

(4-1)
The demand response system 100 of this embodiment includes a heating device 20 as a facility device, and a control device 200 including an aggregator 10 and a controller 21. The heating device 20 includes an outdoor unit 30 as a heat source device that uses electricity, heating units 40a and 40b as secondary devices, and an aqueous medium circuit 80 as a circulation path. The heating units 40a and 40b use the heat of the outdoor unit 30. The aqueous medium circuit 80 circulates an aqueous medium for conveying the heat of the outdoor unit 30 to the heating units 40a and 40b. The control device 200 receives a power adjustment request from the host side, and controls the heating device 20 according to the power adjustment request. The aqueous medium circuit 80 includes a heat storage tank 60 that stores the aqueous medium, and three-way valves 61a and 61b and a second pump 64 as switching means. The three-way valves 61 a and 61 b switch between a first state in which the aqueous medium flows into the heat storage tank 60 and a second state in which the aqueous medium does not flow into the heat storage tank 60. The second pump 64 switches between a third state in which the aqueous medium flows into the heat storage tank 60 and a fourth state in which the aqueous medium does not flow into the heat storage tank 60. The control device 200 includes a three-way valve control unit 23a and a second pump control unit 23d as switching control units for switching the three-way valves 61a and 61b and the second pump 64, respectively. Each of the three-way valve control unit 23a and the second pump control unit 23d switches between the three-way valves 61a and 61 and the second pump 64 based on the power adjustment request.

  Here, based on the power adjustment request, the three-way valves 61 a and 61 switch between a first state in which the aqueous medium flows into the heat storage tank 60 and a second state in which the aqueous medium does not flow into the heat storage tank 60. Further, based on the power adjustment request, the second pump 64 switches between a third state in which the aqueous medium flows into the heat storage tank 60 and a fourth state in which the aqueous medium does not flow into the heat storage tank 60. Therefore, in the demand response system 100, it is easy to appropriately use the heat storage tank 60, and it is possible to realize a demand response with high accuracy according to a power adjustment request.

(4-2)
In the demand response system 100 of the present embodiment, the three-way valve control unit 23a switches the switching means so that the control device 200 enters the first state when the control device 200 receives a power adjustment request, and the control device 200 issues a power adjustment request. When it is not received, the switching means is switched so as to be in the second state. In addition, the second pump control unit 23d switches the switching unit so as to be in the third state when the control device 200 receives the power adjustment request, and the second pump control unit 23d performs the fourth operation when the control device 200 does not receive the power adjustment request. The switching means is switched so as to be in a state.

  Here, when there is a power adjustment request, control is performed so that the aqueous medium flows through the heat storage tank 60. Therefore, when a power adjustment request for requesting suppression of power usage is received, the heat storage tank 60 stores the heat storage tank 60. Heat can be stored in the heat storage tank 60 when the heating units 40a and 40b can use the heat and the power adjustment request that requires the promotion of the power consumption is received. As a result, it is possible to realize demand response with high accuracy.

(4-3)
In the demand response system 100 of the present embodiment, the control device 200 further includes a determination unit 12a that determines whether or not the control device 200 may receive a power adjustment request in a predetermined period. The second pump control unit 23d determines the amount of heat stored in the heat storage tank 60 when the determination unit 12a determines that the control device 200 may receive a power adjustment request that requests promotion of power usage during a predetermined period. In order to decrease, the 2nd pump 64 is operated so that it may be in the 3rd state.

  Here, the second pump 64 is controlled so as to reduce the heat storage amount of the heat storage tank 60 when it is determined to receive a power adjustment request that requires promotion of power usage during a predetermined period. When a power adjustment request that requires promotion is received, it is easy to respond to the power adjustment request. As a result, it is possible to realize demand response with high accuracy.

(4-4)
In the demand response system 100 of this embodiment, the control apparatus 200 is further provided with the outdoor unit control part 23b as a heat source apparatus control part, and the heating unit control part 23e as a secondary side apparatus control part. The outdoor unit control unit 23b controls the operation / stop of the outdoor unit 30. The heating unit controller 23e controls the operation / stop of the heating units 40a and 40b. When the determination unit 12a determines that there is a possibility that the control device 200 may receive a power adjustment request for requesting the promotion of power usage during a predetermined period, and the heating units 40a and 40b are stopped, the outdoor unit The control unit 23b does not operate the outdoor unit 30. In this case, the heating unit controller 23e operates the stopped heating units 40a and 40b.

  Here, the heating unit 40a, without operating the outdoor unit 30 when it is determined that it receives a power adjustment request for requesting the promotion of power use during a predetermined period and the heating unit 40a, 40b is stopped. 40b is activated. Therefore, the heat stored in the heat storage tank 60 is used for the heating units 40a and 40b, and the amount of heat stored in the heat storage tank 60 decreases. As a result, the demand response system 100 can easily store heat in the heat storage tank 60 when it receives a power adjustment request that requires promotion of power consumption.

(4-5)
In the demand response system 100 of the present embodiment, the control device 200 further includes a determination unit 12a and an outdoor unit control unit 23b as a heat source device control unit. The determination unit 12a determines whether or not the control device 200 may receive a power adjustment request during a predetermined period. The outdoor unit control unit 23b controls the operation / stop of the outdoor unit 30. When determination unit 12a determines that control device 200 may receive a power adjustment request for requesting suppression of power consumption during a predetermined period, and heating units 40a and 40b are stopped Moreover, the three-way valve control unit 23a as the switching control unit switches the three-way valves 61a and 61b so as to be in the first state. In that case, the outdoor unit control unit 23 b operates the outdoor unit 30 to increase the amount of heat stored in the heat storage tank 60.

  Here, when it is determined that a power adjustment request for suppressing the amount of power used during a predetermined period is received and the heating units 40a and 40b are stopped, the aqueous medium is caused to flow into the heat storage tank 60, and the outdoor unit 30 heat is stored in the heat storage tank 60. For this reason, the heat storage tank 60 stores heat before receiving the power adjustment request for requesting suppression of the power consumption, and receives the power adjustment request for requesting suppression of the power usage, so that the heat storage tank 60 stored in advance is stored. The heat of the can be utilized. That is, in the demand response system 100, when receiving a power adjustment request for requesting suppression of power consumption, it is easy to respond to the power adjustment request, and it is possible to realize a demand response with high accuracy.

(4-5)
In the demand response system 100 of the present embodiment, the control device 200 includes a controller 21 and an aggregator 10. The controller 21 is provided in each of the plurality of heating devices 20 and controls each of the heating devices 20. The aggregator 10 controls the plurality of controllers 21 in an integrated manner.

  Here, the demand response can be realized with high accuracy by controlling the heating device 20 by either the individual controller 21 of the heating device 20 or the aggregator 10 that controls the controller 21 of the heating device 20.

(5) Modifications Modifications of the present embodiment are shown below. Note that a plurality of modified examples may be combined as appropriate within a range that does not contradict each other.

(5-1) Modification A
Although the outdoor unit 30 which is the main heat source of the heating device 20 has been described as an example of the heat source device in the above embodiment, the present invention is not limited to this. For example, when the electric heater 52 is considered as an example of a heat source device and is operated as in the above embodiment, the same features as in the above embodiment can be obtained.

(5-2) Modification B
In the above embodiment, the three-way valves 61a and 61b and the second pump 64 have been described as an example of the switching unit. However, the present invention is not limited to this, and other configurations may be used as the switching unit. For example, in the demand response system, a plurality of electromagnetic valves are provided in the aqueous medium circuit 80 and the opening and closing of the electromagnetic valves is controlled, so that the aqueous medium flows into the heat storage tank 60 and the aqueous medium flows into the heat storage tank 60. You may be comprised so that it may switch with a state which is not.

(5-3) Modification C
In the above embodiment, as in the seventh time zone in FIG. 5, the determination unit 12a determines that there is a possibility that the aggregator 10 may receive a power adjustment request for requesting promotion of power usage during a predetermined period. In addition, when there is no heating load (while the heating units 40a and 40b are stopped), the heating operation of the heating units 40a and 40b is performed using the heat storage tank 60 as a heat source, but the present invention is not limited to this.

  For example, in the demand response system 100, the determination unit 12a determines that there is a possibility that the aggregator 10 receives a power adjustment request for requesting the promotion of power usage during a predetermined period, and the heating units 40a and 40b are operated. The outdoor unit controller 23b may stop the outdoor unit 30. That is, before the heating load becomes 0 in the middle of the sixth time zone in FIG. 5 (before the stop command for the heating units 40a and 40b is input to the remote controller (not shown)), the heat storage tank 60 is used as the heat source. The heating operation of the heating units 40a and 40b may be started.

  Again, since the heating units 40a and 40b are operated using the heat stored in the heat storage tank 60, the amount of heat stored in the heat storage tank 60 is reduced. Therefore, in the demand response system 100, it is easy to store heat in the heat storage tank 60 when receiving a power adjustment request that requires promotion of power consumption. Moreover, since the heat stored in the heat storage tank 60 is effectively used, energy is saved.

(6-4) Modification D
In the above embodiment, as in the third time zone in FIG. 5, when the determination unit 12 a determines that the aggregator 10 may receive a power adjustment request for requesting suppression of power usage during a predetermined period. In addition, when there is no heating load (while the heating units 40a and 40b are stopped), the heat storage amount of the heat storage tank 60 is increased using the outdoor unit 30 as a heat source, but the present invention is not limited to this.

  For example, the determination unit 12a determines that there is no possibility that the aggregator 10 receives a power adjustment request for requesting the promotion of power usage during a predetermined period, and the heating units 40a and 40b are stopped. In this case, the three-way valve control unit 23a may switch the three-way valves 61a and 61b so as to be in the first state. Moreover, the outdoor unit control part 23b may increase the heat storage amount of the heat storage tank 60 by operating the outdoor unit 30.

  Here, when it is determined that there is no possibility that the aggregator 10 receives a power adjustment request for requesting the promotion of the use of power during a predetermined period, and the heating units 40a and 40b are stopped, an aqueous medium is added to the heat storage tank 60. And the heat of the outdoor unit 30 is stored in the heat storage tank 60. Therefore, the heating units 40a and 40b can immediately obtain necessary heat at the time of activation, and can realize the heating device 20 with high responsiveness.

  In addition, here, since it is stored in the heat storage tank 60 when it is determined that there is no possibility of requesting the promotion of power usage during a predetermined period, a power adjustment request for requesting the promotion of power usage has been received. In such a case, the heat storage tank 60 has already sufficiently stored heat, and it is difficult to generate a state in which heat cannot be stored any more. Therefore, when the aggregator 10 receives a power adjustment request for requesting the promotion of power use, it is easy to respond to the power adjustment request.

(6-5) Modification E
In the above embodiment, the power adjustment request is not received in the second time zone (from 7:00 to 8:00 in the morning) in FIG. 5 as in FIG. 4, but the aggregator 10 suppresses the power consumption during this time. Assume that a power adjustment request is received.

  In this case, since the aggregator 10 requires suppression of power consumption, in principle, the heat of the aqueous medium in the heat storage tank 60 is used as in the fifth time zone of FIG. 5 of the above embodiment. Thus, the heating units 40a and 40b are operated.

  However, even if the aggregator 10 has received a power adjustment request that requires suppression of power consumption, if the temperature of the aqueous medium in the heat storage tank 60 measured by the heat storage tank temperature sensor 60a is lower than a predetermined temperature, the above Similarly to the second time zone of FIG. 5 in the embodiment, the heating device 20 may be operated. In other words, even when the control device 200 accepts a power adjustment request that requires suppression of power consumption, the heating unit 40a, when the temperature of the aqueous medium in the heat storage tank 60 is out of the predetermined range, The second pump control unit 23d may stop the second pump 64 so that the aqueous medium does not flow from 40b to the heat storage tank 60.

  Therefore, even when the temperature of the aqueous medium in the heat storage tank 60 and the temperature of the aqueous medium required by the heating units 40a and 40b are different from each other, the heating units 40a and 40b immediately have water at the required temperature. It is easy to obtain a medium, and the responsive heating device 20 is realized.

(6-6) Modification F
In the above embodiment, the aggregator 10 includes the determination unit 12a. However, each controller 21 may have the function of the determination unit 12a. Moreover, in the said embodiment, although the control part 12 of the aggregator 10 produces | generates the control command of the controller 21 using judgment of the judgment part 12a, it is not limited to this, Each function of the control part 23 The content of the control command for the units 23a to 23e may be determined by the control unit 23 of the controller 21.
