Description

Heating system and heating system control method

The present invention relates to a method for controlling a heating system using hot water, and relates to a method for controlling a heating system including a plurality of heating devices such as a radiator and floor heating.

Patent Document 1 discloses a conventional hot water heater. The hot water heater disclosed in Patent Document 1 controls the room temperature of a room by supplying hot water from a boiler to a radiator installed in each room. Moreover, the flow volume of the hot water supplied to each radiator can be adjusted with a valve. Each valve is equipped with a wireless receiver and adjusts the flow rate of hot water according to the wireless signal received from the remote controller.

German Patent Application Publication No. 42221094

However, Patent Document 1 only discloses that the room temperature of each room can be individually controlled, and does not disclose heat control for overall optimization of the apartment house.

Therefore, an object of the present invention is to provide a heating system and a heating system control method that achieves both reduction in total heat consumption and maintenance of comfort in each room.

A method for controlling a heating system according to an aspect of the present invention controls a plurality of heating apparatuses that are installed in each of a plurality of rooms and that heat the generated rooms by radiating heat generated by a heat supply source. Is the method. Specifically, in the heating system control method, an acquisition step of acquiring from the heat supply source a heat dissipation suppression instruction that requests suppression of heat dissipation from the plurality of heating devices, and the heat dissipation suppression in the acquisition step. In response to obtaining the instruction, a heat dissipation stop step for stopping heat dissipation of the plurality of heating devices, a detection step for detecting the room temperature of each of the plurality of rooms, and a room temperature detected in the detection step, A heat radiation restarting step of individually restarting heat radiation of the heating device installed in each room.

As described above, the heat dissipation of each heating device is temporarily stopped according to the request from the heat supply source, and then the heat dissipation of the heating device is individually resumed according to the room temperature of each room, thereby reducing the total heat consumption. And maintaining the comfort of each room. Note that “stopping heat dissipation of the heating device” includes not only literally stopping the heating device literally but also including a state in which a slight amount of heat is radiated to the heating device. The “slight amount of heat” in this case is not radiated for the purpose of heating the room, but is radiated for the purpose of maintaining the function of the heating system, for example, preventing the flow path from freezing. Is.

Further, a target temperature may be set in advance for each of the plurality of heating devices. In the heat radiation restarting step, heat radiation is resumed in the heating device in the first mode in which the room temperature is raised to the target temperature in order from the room in which the room temperature detected in the detection step has reached a predetermined threshold temperature. You may let them.

In this way, it is possible to prevent the room temperature of some rooms from being extremely lowered by restarting heat radiation in order from the room heating device in which the room temperature has reached the threshold temperature. As a result, the comfort of each room can be leveled.

Furthermore, the control method for the heating system may include a threshold temperature determining step for individually determining the target temperature set for each of the plurality of heating devices. In the threshold temperature determining step, the threshold temperature of each of the plurality of heating devices may be individually determined so that the threshold temperature increases as the room temperature decrease rate of the installed room increases.

Therefore, in the room with low comfort, priority is given to maintaining comfort over reduction of heat dissipation, and reduction of heat dissipation is emphasized in rooms with high comfort. That is, the reduction of the total heat consumption and the maintenance of the comfort of each room can be achieved in a balanced manner.

Furthermore, the control method of the heating system includes a prediction step of predicting, for each heating device, a suppression heat amount that is a heat dissipation amount suppressed by the heat dissipation suppression instruction, and a suppression for each heating device predicted in the prediction step. A notification step of notifying the heat supply source of a total suppression heat amount that is a total amount of heat.

This makes it possible to avoid excessive heat generation.

Further, a target temperature may be set in advance for each of the plurality of heating devices. The heat dissipation suppression instruction acquired in the acquisition step may include information for specifying a suppression end time that is a time at which suppression of heat dissipation ends. In the heat release restarting step, the heating device in the first mode in which the room temperature is increased to the target temperature in order from the room where the difference between the room temperature and the target temperature detected at the detection end time is large. The heat dissipation may be resumed.

In this way, the comfort of each room can be leveled by restarting in order from the room heating device in which the difference between the room temperature and the target temperature at the suppression end time is large.

Further, in the heat radiation restarting step, each of the plurality of heating devices radiates heat in the second mode in which the room temperature at the suppression end time is maintained from the suppression end time until the heat dissipation is restarted in the first mode. You may let them.

Further, in the heat radiation restarting step, at the timing when the room temperature of the room in which the heating device that radiates heat in the first mode reaches the target temperature, the next heating device has the first mode. The heat release may be resumed.

Further, in the heat radiation restarting step, the heat radiation amount per unit time of the heating device that radiates heat in the first mode may be increased as the difference between the room temperature and the target temperature at the suppression end time is larger.

The heating system according to an aspect of the present invention heats each of a plurality of rooms with heat generated by a heat supply source. Specifically, the heating system includes a plurality of heating devices installed in each of the plurality of rooms, and a control unit that controls the operation of each of the plurality of heating devices. And the said control part acquires the heat dissipation suppression instruction | indication which requests | requires suppressing the heat dissipation from these heating apparatuses from the said heat supply source, The detection part which detects the room temperature of each of these rooms And, in response to the acquisition of the heat radiation suppression instruction by the acquisition unit, the heat dissipation of the plurality of heating devices is stopped, and the heating installed in each room according to the room temperature detected by the detection unit An operation control unit for individually restarting heat dissipation of the device.

The control unit includes a first control unit including the acquisition unit and a first operation control unit corresponding to a part of the operation control unit, the detection unit, and another part of the operation control unit. And a second control unit provided for each room.

Furthermore, a target temperature may be set in advance for each of the plurality of heating devices. The first operation control unit transmits a heat release suppression start time included in the heat release suppression instruction acquired by the acquisition unit and a threshold temperature indicating a lower limit value of a room temperature to the second control unit of each room. Also good. The second operation control unit stops heat dissipation of the heating device at the heat release suppression start time acquired from the first operation control unit, and the room temperature detected by the detection unit is acquired from the first operation control unit. When the threshold temperature is reached, the heating device may resume heat radiation in the first mode in which the room temperature is raised to the target temperature.

According to the present invention, it is possible to reduce the heat consumption of the entire heating system while improving the comfort individually according to the characteristics of each room. Thereby, the peak cut of heat consumption can be achieved, maintaining a user's comfort.

Hereinafter, a heating system and a heating system control method according to an embodiment of the present invention will be described with reference to the drawings. In addition, this invention is specified based on description of a claim. Therefore, among the constituent elements in the following embodiments, constituent elements not described in the claims are not necessarily required to achieve the object of the present invention. That is, the following embodiment explains a more preferable embodiment of the present invention. Each figure is a mimetic diagram and is not necessarily illustrated strictly.

First, an environment (infrastructure) to which a heating system according to an embodiment of the present invention is applied will be described with reference to FIG. FIG. 1 is a schematic diagram for explaining the mechanism of district heat supply, and shows how hot water circulates between a district heat supplier (heat source) 100 and a district heat consumer 110. Show.

The district heat supplier 100 is a business that generates heat during operation, and corresponds to, for example, the factory 101 and the power plant 102. That is, the factory 101 and the power plant 102 shown in FIG. 1 discharge hot water (for example, pressurized hot water of 110 ° C.) generated using waste heat generated during operation into the flow path.

In the above example, warm water is generated using waste heat. However, the present invention is not limited to this, and facilities for generating hot water to be supplied to the regional heat consumer 110 are also shown in FIG. It can be included in the heat supplier 100. Moreover, it is not limited to the heat | fever produced | generated artificially, It cannot be overemphasized that warm water may be produced | generated using geothermal etc. That is, the district heat supplier 100 is not limited to the example of FIG. 1, and includes all facilities that can stably generate and supply hot water.

The district heat consumer 110 is a facility that uses hot water generated by the district heat supplier 100, and corresponds to, for example, a detached house 111, an apartment house 112, and the like. More specifically, the hot water generated by the district heat supplier 100 is consumed by a heating device and a hot water supply device installed in each room in the detached house 111 and the apartment house 112, and again the district heat supplier. Reflux to 100. In addition, the district heat consumer 110 is not limited to the example of FIG. 1, but includes all facilities that consume heat such as an office, a store, a school, and a hospital.

Next, with reference to FIG. 2A, FIG. 2B, FIG. 3, and FIG. 2A and 2B are diagrams showing the transition of the amount of heat consumed by the district heat consumer 110 of FIG. FIG. 3 is a diagram illustrating an example of the apartment house 112. FIG. 4 is a diagram showing changes in room temperature in each room of the apartment house 112 shown in FIG.

For example, in an apartment house in a cold region, as shown in FIG. 2A, the amount of heat consumed by the heating device (hereinafter referred to as “heating amount of heat”) is substantially constant throughout the day. On the other hand, the amount of heat consumed by the hot water supply device (hereinafter referred to as “hot water supply heat amount”) is a predetermined time of the day (in the example of FIG. 2A, between 8 o'clock and 9 o'clock and between 21 o'clock and 22 o'clock) It is concentrated and rarely occurs at other times. As a result, in the example shown in FIG. 2A, a peak of heat consumption occurs in a time zone in which the amount of hot water supply is concentrated (hereinafter referred to as “peak time zone”).

When a peak occurs in the amount of heat consumed as shown in FIG. 2A, the district heat supplier 100 must have a biothermal capacity that matches the peak. In addition, the district heat supplier 100 may have to reheat using expensive fuel (for example, fossil fuel) in order to supply sufficient hot water during peak hours.

Therefore, in order to solve the above-described problem, for example, it is conceivable to stop all the heating devices during peak hours. As a result, as shown in FIG. 2B, the heating heat amount in the peak time zone becomes zero, so that the peak of the heat consumption amount is leveled.

However, when all the heating devices are stopped during peak hours, the following new problems arise. For example, as shown in FIG. 3, when considering an apartment house 112 having 12 rooms in total of 4 rooms on each of 3 floors, the heat insulation performance (heat dissipation performance) generally differs depending on the position of the room. More specifically, room A3 in which four of the six surfaces are in contact with the outside air, room A2 in which three of the six surfaces are in contact with the outside air, and two of the six surfaces are in contact with the outside air. The room B2 has the highest heat insulation performance of the room B2, the heat insulation performance of the room A2 is the next highest, and the heat insulation performance of the room A3 is the lowest.

Therefore, the change in room temperature when the heating devices installed in the rooms A2, A3, and B2 are simultaneously stopped differs depending on the room. For example, FIG. 4 shows a simulation result of room temperature changes in the rooms A2, A3, and B2 when the heating device is stopped from 8:00 to 9:00 (denoted as “stop time zone” in FIG. 4). The size of each room of the apartment house 112 was 10 meters wide, 7 meters deep, and 2.5 meters high. In addition, the transition of the outside air temperature, which is the premise of the simulation, is also shown in FIG.

As is clear from FIG. 4, the room temperatures of the rooms A2, A3, and B2 during the stop time period are monotonously decreasing. At this time, the room temperature decreasing rate of the room A3 having the lowest heat insulating performance is the fastest, and the room temperature decreasing speed of the room B2 having the lowest heat insulating performance is the slowest. That is, the room temperature at 9:00 am, which is the end time of the stop time zone, is lowest in the room A3 and highest in the room B3. Thus, when the heating devices of all the rooms are uniformly stopped, The first problem that comfort differs greatly arises.

Furthermore, at the time of 9:00 am, which is the end time of the stop time zone, the heating devices in each room restart their operations all at once in order to raise the room temperature to the original set temperature. As a result, as shown in FIG. 2B, in the time zone (9 to 10 o'clock and 22:00 to 23 o'clock) immediately after the initial peak time zone (8 o'clock to 9 o'clock and 21:00 to 22:00) A second problem that a new peak occurs is generated.

Therefore, an example of a heating system and a heating system control method for solving the first and second problems will be described with reference to FIGS. 5 and 6. FIG. 5 is a schematic block diagram of a heating system according to an aspect of the present invention. FIG. 6 is a flowchart illustrating a control process of the heating system according to one aspect of the present invention.

First, the heating system 10 according to one aspect of the present invention includes a control unit 20 and a plurality of

heating devices

31, 32, 33, 34, 35, and 36, as shown in FIG. Each of the heating devices 31 to 36 is installed in a separate room and heats the installed room by radiating heat supplied from the district heat supplier 100.

The control unit 20 exchanges information with the district heat supplier 100 and controls the operation of the heating devices 31 to 36 individually. More specifically, the control unit 20 includes a communication unit 21, a detection unit 22, an operation control unit 23, and a prediction unit 24.

The communication unit 21 is a communication interface that transmits and receives various types of information to and from the district heat supplier 100 through a communication line. Although the specific example of the information transmitted / received is not specifically limited, For example, the communication part 21 receives the heat radiation | emission suppression instruction | indication (it describes as "SO (Shut Off) signal" hereafter) from the district heat supplier 100, and is total suppression calorie | heat amount. Is transmitted to the district heat supplier 100. The communication unit 21 is an example of an acquisition unit that acquires a heat dissipation suppression instruction.

Note that the SO signal is a signal that requests suppression of heat dissipation of the heating devices 31 to 36. The SO signal includes information for specifying a time zone for suppressing heat dissipation (hereinafter referred to as “SO time zone”), that is, the start time of the SO time zone (hereinafter referred to as “SO start time”) and the SO time. Information specifying the band end time (hereinafter referred to as “SO end time”) is included. The total suppression heat amount is a predicted value of the heat dissipation amount that can be suppressed in the SO time period as a result of the heat dissipation of the heating devices 31 to 36 being suppressed by the SO signal.

Detecting unit 22 detects various information (particularly temperature information). More specifically, the detection unit 22 detects the room temperature of each room in which the heating devices 31 to 36 are installed. Moreover, the detection part 22 detects the outside temperature around the building where the heating system 10 is installed. Then, the detection unit 22 notifies the operation control unit 23 and the prediction unit 24 of the detected temperature information.

The operation control unit 23 individually controls the operation states of the heating devices 31 to 36. For example, as illustrated in FIG. 6, the operation control unit 23 stops the operation of all the heating devices 31 to 36 in response to obtaining the SO signal from the district heat supplier 100 through the communication unit 21 (S101). (S102). Further, the operation control unit 23 individually restarts the operation of the heating devices 31 to 36 installed in each room according to the room temperature detected by the detection unit 22 (S103) (S104). The timing for resuming the operation of the heating devices 31 to 36 will be described in detail in Embodiments 1 to 3 described later.

The prediction unit 24 predicts the total suppression heat amount. The total suppression heat amount is, for example, the amount of heat consumed when the heating devices 31 to 36 are normally operated during the SO time zone and the control shown in FIG. 6 for the heating devices 31 to 36 during the SO time zone. This corresponds to the difference from the amount of heat consumed. Further, the total suppression heat amount is obtained, for example, by predicting the heat release amount (hereinafter referred to as “suppression heat amount”) that can be suppressed in the SO time zone for each of the heating devices 31 to 36 and summing them.

Hereinafter, a heating system and a heating system control method according to Embodiments 1 to 3 of the present invention will be described with reference to the drawings.

(Embodiment 1)
First, the configuration of the heating system according to Embodiment 1 will be described with reference to FIGS. 7A and 7B. FIG. 7A is a diagram illustrating an example of equipment in the apartment house 112 necessary for heating each room with hot water supplied from the district heat supplier 100. FIG. 7B is an enlarged view of one of the rooms shown in FIG. 7A.

7A and 7B, the housing complex 112 is provided with a heat exchanger 210, a calorimeter 211, a pump 212, an outside air temperature sensor 213, and a heating system controller 214. Each room of the apartment house 112 includes a radiator 201, a valve 202, a room temperature sensor 203, and a heating device control unit 204. In FIGS. 7A and 7B, solid arrows indicate the flow of hot water, and broken arrows indicate the flow of information (signal).

The heat exchanger 210 is a facility for performing heat exchange between the hot water circulating between the district heat supplier 100 and the heat exchanger 210 and the hot water circulating between the heat exchanger 210 and each room. Typically, it is installed in the basement of the apartment house 112. More specifically, the heat exchanger 210 performs heat exchange between high-temperature hot water flowing from the district heat supplier 100 and low-temperature hot water flowing from each room. Then, the hot water whose temperature has dropped from the heat exchanger 210 to the district heat supplier 100 circulates, and the hot water whose temperature has risen circulates from the heat exchanger 210 to each room.

The calorimeter 211 measures the amount of heat exchanged by the heat exchanger 210. Specifically, the calorimeter 211 has a temperature (first temperature) of high-temperature hot water from the district heat supplier 100 to the heat exchanger 210 and a low-temperature reflux that returns from the heat exchanger 210 to the district heat supplier 100. Measures the amount of heat exchanged in the heat exchanger 210 by measuring the temperature of the hot water (second temperature) and multiplying the difference between the first and second temperatures by the flow rate of the hot water flowing into the heat exchanger 210 To do. The amount of heat measured by the calorimeter 211 is used for, for example, calculation of a district heat usage fee charged to the apartment house 112.

The pump 212 is a facility that controls the flow rate of hot hot water from the heat exchanger 210 toward each room, and is typically installed in the basement of the apartment house 112. For example, the pump 212 can change the flow rate of hot water from the heat exchanger 210 to each room within a range of 20 to 60 (l / min) according to control from the heating system control unit 214.

The outside air temperature sensor 213 detects the outside air temperature around the apartment house 112 and notifies the heating system control unit 214 of it. For example, the outside air temperature sensor 213 in FIG. 7A corresponds to the detection unit 22 in FIG.

The heating system control unit 214 controls the entire heating system by exchanging information between the district heat supplier 100 and the heating device control unit 204 of each room. The heating system control unit 214 in FIG. 7A corresponds to, for example, the communication unit 21, a part of the operation control unit 23, and the prediction unit 24 in FIG. 5.

The radiator 201 heats the room by radiating the heat of the hot water supplied from the heat exchanger 210. The radiator 201 may radiate the heat of hot water into the air, or may be floor heating that warms the floor with the heat of hot water. One radiator 201 may be installed in each room, or a plurality of radiators 201 may be installed in each room (two are installed in the examples of FIGS. 7A and 7B).

The valve 202 controls the flow rate of the hot water flowing from the heat exchanger 210 into the radiator 201. The valve 202 has a function of communicating with the heating device control unit 204 and can change the flow rate in accordance with an instruction from the heating device control unit 204. For example, as disclosed in Patent Document 1, a valve (Thermostatic Radiator Valve: TRV) equipped with a wireless receiver may be used. One valve 202 may control the flow rate of hot water flowing into one radiator 201, or one valve 202 may control the flow rate of hot water flowing into a plurality of radiators 201.

The room temperature sensor 203 detects the room temperature of the room and notifies the heating device control unit 204 of it. For example, the room temperature sensor 203 in FIG. 7A corresponds to the detection unit 22 in FIG.

The heating device control unit 204 exchanges information with the heating system control unit 214 to thereby provide a radiator 201 and a valve 202 installed in the room (hereinafter collectively referred to as “heating device”). To control. Moreover, the heating apparatus control part 204 receives the input of the target temperature of a room from a user. Then, in a time zone other than the SO time zone, the heating device control unit 204 controls the operation of the heating device so that the room temperature of the room approaches the target temperature. For example, the heating device control unit 204 in FIG. 7A corresponds to a part of the operation control unit 23 in FIG.

Note that the heating device control unit 204 can select any one of the stop mode, the first mode, and the second mode as the operation mode of the heating device. The stop mode is an operation mode in which heat dissipation is completely stopped (or only the minimum heat necessary for maintaining the function of the heating system is dissipated). The first mode is an operation mode in which heat necessary for raising the room temperature to a preset target temperature is radiated. The second mode is an operation mode in which heat necessary for maintaining the current room temperature is radiated.

And the heating apparatus control part 204 can switch each said mode by controlling the flow volume of the warm water supplied to the radiator 201 through the valve | bulb 202. FIG. That is, the amount (heat amount) of hot water supplied to the radiator 201 when the first mode is selected is larger than the amount (heat amount) of hot water supplied to the radiator 201 when the second mode is selected.

Moreover, the apartment house 112 may further include a hot water supply device that supplies hot water using heat from the district heat supplier 100. However, in this specification, control of the heating device will be mainly described, and thus illustration and description of the hot water supply device are omitted.

Next, with reference to FIG. 8, the outline of the control processing of the heating system according to Embodiment 1 will be described. In Embodiment 1, when the SO signal is received from the district heat supplier 100 (S210), the threshold temperature is determined (S220). The threshold temperature is a value indicating a lower limit value of room temperature. Next, in order to stop the heat radiation from all the radiators 201 at the SO start time, all the valves 202 are closed (S230). Thereafter, in order from the room in which the room temperature reaches the threshold temperature (S240), the valve 202 is opened in order to resume the heat radiation of the radiator 201 (S250).

In the first embodiment, among the above processes, steps S210 and S220 are executed by the heating system control unit 214, and steps S230, S240, and S250 are executed by the heating device control unit 204. That is, in Embodiment 1, the function of the operation control unit 23 in FIG. 5 is shared by the heating system control unit 214 and the heating device control unit 204. However, the above division of roles is an example, and the present invention is not limited to this.

Next, with reference to FIG. 9, FIG. 10A, FIG. 10B, FIG. 11, and FIG. 12, the control process of the heating system according to Embodiment 1 will be described in detail. FIG. 9 is a diagram illustrating an example of information transmitted and received between each component. FIG. 10A is a flowchart of the heating system control process executed by the heating system control unit 214. FIG. 10B is a flowchart of the suppression heat amount notification process executed by the heating system control unit 214. FIG. 11 is a flowchart of the heating device control process executed by the heating device control unit 204 in each room. FIG. 12 is a diagram showing changes in temperature and total heat dissipation of the rooms A2, A3, and B2 of the apartment house 112 shown in FIG. 3 when the control process of the heating system according to Embodiment 1 is executed. is there.

First, the heating device control unit 204 in each of the rooms A2, A3, and B2 receives the input of the target temperature from the user in advance as shown in FIG.

FIG. 9 is a diagram illustrating an example of information transmitted and received between each component. As shown in FIG. 9, between the district heat supplier 100 and the heating system control unit 214, the SO signal is transmitted from the district heat supplier 100 to the heating system control unit 214, and conversely, the total suppression heat amount is controlled by the heating system control. It is transmitted from the section 214 to the district heat supplier 100. Further, between the heating system control unit 214 and the heating device control unit 204, the SO start time, the SO end time, and the threshold temperature are transmitted from the heating system control unit 214 to the heating device control unit 204, and conversely, the heat release is resumed. The report is transmitted from the heating device control unit 204 to the heating system control unit 214. Then, the heating device control unit 204 instructs the valve 202 to open and close the valve, and acquires the room temperature from the room temperature sensor 203. Furthermore, the user can input the set target temperature of the room to the heating device control unit 204.

For example, if the target temperatures of all the rooms A2, A3, and B2 are 21 ° C., the room heating devices in the time zone up to 8 o'clock in FIG. It is kept at 21 ° C. Further, the total amount of heat dissipated in the rooms A2, A3, B2 during this period (hereinafter referred to as “total heat dissipation amount”) is kept constant. In the example of FIG. 12, the target temperatures of the rooms A2, A3, and B2 are the same, but needless to say, the target temperatures may be different for each room.

Next, as shown in FIG. 10A, the heating system control unit 214 receives an SO signal from the district heat supplier 100 (S301). This SO signal includes information for specifying the SO start time and the SO end time. In the example of FIG. 12, the SO start time is 8:00 and the SO end time is 9:00.

A specific example of “information for specifying the SO start time and the SO end time” is not particularly limited. For example, “SO start time: 8 o'clock, SO end time: 9 o'clock”. And the SO end time itself, or information indicating the SO start time and the length of the SO time zone, such as “SO start time: 8 o'clock, SO time: 1 hour”. Alternatively, the SO signal may not explicitly include the SO start time, and the SO signal reception time may be the SO start time. In this case, the SO signal includes information indicating the SO end time or the length of the SO time.

Next, the heating system control unit 214 executes threshold temperature determination processing (S302). In the first embodiment, a threshold temperature common to all rooms is determined. In this example, it is assumed that the threshold temperature is determined to be 19 ° C.

In addition, the threshold temperature in Embodiment 1 may be a fixed value set in advance in the heating system control unit 214, for example. Alternatively, a table indicating a correspondence relationship between the outside air temperature and the threshold temperature may be held in the heating system control unit 214, and a threshold temperature corresponding to the outside air temperature detected by the outside air temperature sensor 213 may be employed. In this case, the correspondence relationship between the outside air temperature and the threshold temperature held in the table needs to be derived in advance by simulation or the like using past weather data in an area where the apartment house 112 is located.

Next, the heating system controller 214 notifies the SO start time and SO end time acquired from the SO signal and the threshold temperature determined in the threshold temperature determination process to the heating device controller 204 of each room (S303). ).

Next, as shown in FIG. 11, the heating device control unit 204 of each room acquires the SO start time, the SO end time, and the threshold temperature from the heating system control unit 214 (S401).

Next, the heating device control unit 204 in each room waits for the SO start time (8 o'clock) to arrive (S402). When the SO start time arrives (YES in S402), the heating device control unit 204 in each room closes the valve 202 (S403). That is, the heating device control unit 204 in each room switches the operation mode of the heating device from the second mode to the stop mode. As a result, the total heat release after 8:00 becomes zero. Moreover, the room temperature of each of the rooms A2, A3, B2 gradually decreases from 8 o'clock.

Next, the heating device control unit 204 in each room compares the room temperature acquired from the room temperature sensor 203 at a predetermined time interval (for example, 1 second) with the threshold temperature acquired in step S401 (S404). When the room temperature reaches the threshold temperature (YES in S404), the heating device control unit 204 opens the valve 202 and causes the radiator 201 to resume heat dissipation (S405). Specifically, the heating device control unit 204 switches the operation mode of the heating device from the stop mode to the first mode. Moreover, the heating device control unit 204 notifies the heating system control unit 214 that heat radiation has been resumed (S406).

FIG. 12 is a diagram showing a change in room temperature and a change in the total heat dissipation in the rooms A2, A3, and B2 when the heating system control process is executed. The horizontal axis represents time, and the vertical axis represents room temperature (° C.) and total heat release (W).

In the example of FIG. 12, the room temperature of the room A3 reaches the threshold temperature (19 ° C.) at 8:25. Therefore, first, the heating device in the room A3 (hereinafter referred to as “heating device A3”) resumes heat radiation. As a result, as shown in FIG. 12, the room temperature of the room A3 gradually increases. Further, the total heat release after 8:25 coincides with the heat release of the heating device A3.

Next, the room temperature of the room A2 reaches the threshold temperature at 8:35, and the heating device in the room A2 (hereinafter referred to as “heating device A2”) resumes heat radiation. As a result, as shown in FIG. 12, the room temperature of the room A2 gradually increases. Further, the total heat release after 8:35 coincides with the total heat release from the heating devices A2 and A3.

Next, when the room temperature of the room A3 reaches the target temperature (21 ° C.) at 8:48, the heating device control unit 204 of the room A3 changes the operation mode of the heating device A3 from the first mode to the second mode. Switch. As a result, the room temperature of the room A3 is kept at 21 ° C. Further, the total heat release after 8:48 is reduced by the amount of switching of the operation mode of the heating device A3 from the first mode to the second mode.

Next, at 9 o'clock, which is the SO end time, heat radiation of the heating devices in all rooms is resumed regardless of whether the room temperature has reached the threshold temperature or not. In the example of FIG. 12, since the heat radiation of the heating devices A2 and A3 has already been resumed, the heating devices in the remaining room B2 (hereinafter referred to as “heating device B2”) resume the heat radiation. As a result, the room temperature of the room B2 gradually increases. Moreover, the total heat radiation after 9 o'clock corresponds to the total heat radiation from the heating devices A2, A3, B2.

Then, the room temperature of the room A2 reaches the target temperature at 9:10, and then the room temperature of the room B2 reaches the target temperature at 9:50. Switch to mode. As a result, the room temperatures of the subsequent rooms A2, A3, and B2 are kept at the target temperature, and the total heat radiation returns to the level before the SO start time.

As described above, even before the end of the SO time period, the room heating apparatus in the room whose room temperature has reached the threshold temperature restarts heat dissipation, thereby preventing the room temperature in some rooms from being extremely lowered. be able to. As a result, the comfort of each room of the apartment house 112 can be leveled.

Also, by temporarily stopping the heat radiation of all the heating devices at the SO start time, it is possible to reduce the heat radiation amount especially in the first half of the SO time zone. In addition, since some heating devices resume heat radiation in the second half of the SO time zone, the amount of heat radiation increases compared to the case where all the heating devices are completely stopped, but normal operation (SO time zone) Compared to the case where the control is not performed), a reduction in the amount of heat radiation can be expected. That is, according to the first embodiment, it is possible to achieve a balance between the reduction of the total heat consumption and the maintenance of the comfort of each room.

Furthermore, by performing the above control, the timing of resuming heat dissipation varies for each heating device. As a result, it is possible to prevent all the heating devices from restarting heat radiation in the first mode at the same time at the SO end time. Thereby, it is possible to prevent the peak of the total heat consumption from occurring immediately after the end of the SO time period.

As described above, since the peak of the total heat consumption immediately after the end of the SO time zone and the SO time zone has been leveled, the district heat supplier 100 has to pay a high price in order to cover the heat amount necessary for the peak time zone. You can enjoy the merit that you do not need to heat with the use of fresh fuel.

Next, with reference to FIG. 10B, the suppressed heat amount notification process executed by the heating system control unit 214 will be described. In addition, this process may be performed simultaneously with the heating system control process of FIG. 10A, for example, and may be performed after the completion of the heating system control process. Further, this process is not an essential process of the present invention and can be omitted.

First, as shown in FIG. 10B, the heating system control unit 214 acquires the outside air temperature around the apartment house 112 from the outside air temperature sensor 213 (S311). The outside temperature acquisition timing may be, for example, the SO start time.

Next, the heating system control unit 214 predicts the suppression heat amount for each room using the acquired outside air temperature (S312). The amount of suppressed heat varies depending on the outside air temperature, the length of the SO time zone, and the heat insulation performance of each room. Therefore, for example, the heating system control unit 214 may calculate and hold the correspondence relationship between the outside air temperature, the length of the SO time zone, and the amount of suppressed heat for each room in advance by simulation or the like.

Next, the heating system control unit 214 predicts the total suppression heat amount by summing the suppression heat amount of each room (S313), and notifies the predicted total suppression heat amount to the district heat supplier 100 through the communication line (S314). . This total suppression heat amount corresponds to, for example, the area of the hatched region in FIG. Thus, the district heat supplier 100 can adjust the amount of heat generated in the SO time zone based on the notified total suppression heat amount. As a result, excessive heat generation can be avoided.

As described above, in the first embodiment, the user's comfort is improved by individually controlling the radiator 201 according to the characteristics of each room while suppressing the amount of heat consumed by the entire apartment house 112 (total amount of heat consumed). Can be maintained.

(Embodiment 2)
Next, with reference to FIG. 13, the outline of the control process of the heating system according to Embodiment 2 will be described. In addition, the same number is attached | subjected to the process which is common in FIG. 8, and description is abbreviate | omitted. 8 and 13 are different from each other in the threshold temperature calculation method (S220 in FIG. 8 and S221 and S222 in FIG. 13), and other processes are common. Specifically, in the second embodiment, the room temperature decrease rate of each room is calculated from the outside air temperature (S221), and the threshold temperature is determined for each room based on this room temperature decrease rate (S222). In the second embodiment, the heating system control unit 214 executes steps S211 and S222. However, the above division of roles is an example, and the present invention is not limited to this.

The threshold temperature determination processing according to the second embodiment will be described in detail with reference to FIGS. FIG. 14 is a flowchart of the threshold temperature determination process executed by the heating system control unit 214. FIG. 15 is a diagram showing changes in temperature and total heat dissipation in the rooms A2, A3, and B2 of the apartment house 112 shown in FIG. 3 when the control process of the heating system according to Embodiment 2 is executed. is there.

In addition, since the structure of the heating system which concerns on Embodiment 2 is common in FIG.5, FIG.7A, FIG.7B, description for the second time is abbreviate | omitted. In the first and second embodiments, only the contents of the threshold temperature determination process (S302) in FIG. 10A are different, and other processes are common.

First, as shown in FIG. 14, the heating system control unit 214 acquires the outside air temperature around the apartment house 112 (S501). The outside temperature acquisition timing may be, for example, the SO start time.

Next, the heating system control unit 214 calculates the temperature decrease rate of each room after stopping heat dissipation (S502). The room temperature decrease rate can be calculated based on, for example, the outside air temperature acquired in step S501 and the heat insulation performance of each room that is held in advance.

Next, the heating system control unit 214 calculates a threshold temperature for each room based on the temperature decrease rate calculated in step S502 (S503). More specifically, the heating system control unit 214 sets the threshold temperature of a room with a fast room temperature decrease rate relatively high, and sets the threshold temperature of a room with a low room temperature decrease rate relatively low.

Here, the room temperature drop rate greatly affects the temperature of the body. Specifically, a room with a fast room temperature decrease rate feels cold even if the room temperature is the same as a room with a slow room temperature decrease rate. That is, in the example of FIG. 15, the sensible temperature of the room A3 is the lowest and the sensible temperature of the room B2 is the highest.

Therefore, the heating system control unit 214 sets the threshold temperature of the room A3 higher than the rooms A2 and B2, and sets the threshold temperature of the room A2 higher than the room B2. In this example, it is assumed that the threshold temperature of the room A3 is set to 19 ° C., the threshold temperature of the room A2 is set to 18 ° C., and the threshold temperature of the room B2 is set to 17 ° C. As a result, the heat release restart time of the room A2 is 8:35 in the example of FIG. 12, but is 8 minutes and 40 minutes late in the example of FIG.

As described above, by setting the threshold temperature of a room having a low sensible temperature (that is, having a fast room temperature decrease rate) to a relatively high temperature, heat radiation can be resumed before the room temperature decreases so much. On the other hand, resumption of heat release can be delayed by setting the threshold temperature of a room having a high body temperature (that is, a room temperature decreasing rate is slow) to be relatively low. As a result, in a room with low comfort, priority is given to maintaining comfort over reduction in heat dissipation, and reduction in heat dissipation is emphasized in rooms with high comfort. That is, according to the second embodiment, the reduction of the total heat consumption and the maintenance of the comfort of each room can be achieved in a balanced manner.

(Embodiment 3)
Next, with reference to FIG. 16, the outline of the control processing of the heating system according to Embodiment 3 will be described. In addition, the same number is attached | subjected to the process which is common in FIG. 8, and description is abbreviate | omitted. First, in the control process of FIG. 16, since the heat radiation of all the heating devices is stopped from the SO start time to the SO end time, a process for calculating the threshold temperature (S220 in FIG. 8) and a process for comparing the room temperature with the threshold temperature. (S240 in FIG. 8) is not necessary. On the other hand, in the control process of FIG. 16, the room temperature of each room at the end time of the SO time zone is acquired (S241), and the heat release restart order of the heating device is determined based on the acquired room temperature (S242). To be added. In the third embodiment, step S241 is executed by the heating device control unit 204, and step S242 is executed by the heating system control unit 214. However, the above division of roles is an example, and the present invention is not limited to this.

The control method of the heating system according to Embodiment 3 will be described in detail with reference to FIGS. 17A, 17B, 18, and 19. FIG. FIG. 17A is a flowchart of the heating system control process executed by the heating system control unit 214. FIG. 17B is a flowchart of the operating condition determination process executed by the heating system control unit 214. FIG. 18 is a flowchart of the heating device control process executed by the heating device control unit 204 in each room. FIG. 19 is a diagram illustrating changes in temperature and total heat dissipation in the rooms A2, A3, and B2 of the apartment house 112 illustrated in FIG. 3 when the control process of the heating system according to Embodiment 3 is performed. is there. In addition, since the structure of the heating system which concerns on Embodiment 3 is common in FIG.5, FIG.7A, FIG.7B, description for the second time is abbreviate | omitted.

First, as shown in FIG. 17A, the heating system control unit 214 receives an SO signal from the district heat supplier 100 (S601). This process is common to step S301 in FIG. 10A. Then, the heating system control unit 214 notifies the heating device control unit 204 of each room of the SO start time and SO end time acquired from the SO signal (S602). The heating system control unit 214 executes the processes so far before the SO start time.

Next, as shown in FIG. 18, the heating device control unit 204 of each room acquires the SO start time and the SO end time from the heating system control unit 214 (S701).

Next, the heating device control unit 204 in each room waits for the SO start time (8 o'clock) to arrive (S702). When the SO start time comes (YES in S702), the heating device control unit 204 in each room closes the valve 202 (S703). That is, the heating device control unit 204 in each room switches the operation mode of the heating device from the second mode to the stop mode. As a result, the total heat release after 8:00 becomes zero. Moreover, the room temperature of each of the rooms A2, A3, B2 gradually decreases from 8 o'clock.

Next, the heating device control unit 204 in each room waits for the arrival of the SO end time (9 o'clock) (S704). In the third embodiment, since heat radiation is not resumed in the SO time zone, as shown in FIG. 19, the room temperatures of the rooms A2, A3, and B2 in the SO time zone all monotonously decrease.

When the SO end time comes (YES in S704), the heating device control unit 204 in each room notifies the heating system control unit 214 of the room temperature detected by the room temperature sensor 203 (S705). In the example of FIG. 19, it is assumed that the room temperature of the room A3 at the SO end time is 15 ° C., the room temperature of the room A2 at the SO end time is 16.5 ° C., and the room temperature of the room B2 at the SO end time is 19 ° C.

Next, returning to FIG. 17A, the heating system control unit 214 determines the operating conditions of the heating device in each room (S603).

Specifically, as shown in FIG. 17B, the heating system control unit 214 acquires the room temperature of each room at the SO end time (S611). That is, the heating system control unit 214 acquires the room temperature at the SO end time detected by the room temperature sensor 203 of each room through the heating device control unit 204 of each room.

Next, the heating system control unit 214 determines the heat release restart order of the heating devices installed in each room (S612). For example, the heating system control unit 214 calculates the difference between the target temperature and the room temperature acquired in step S611 for each room, and sets the heat dissipation restart order so that heat dissipation is restarted in order from the heating device in the room where the difference is large. Just decide. In the example of FIG. 19, since the target temperature of all the rooms is 21 ° C. and the room temperature of each room at the SO end time is as described above, heat radiation is resumed in the order of room A3, room A2, and room B3. become.

In addition, when determining the heat radiation resumption order by the above method, the heating system control unit 214 needs to acquire the target temperature of each room from the heating device control unit 204. The target temperature acquisition timing is not particularly limited. For example, the target temperature may be acquired together with the room temperature at the SO end time at the timing of step S611. Alternatively, the heating system control unit 214 may acquire and store the new target temperature from the heating device control unit 204 at the timing when the new target temperature is set in the heating device control unit 204.

In the example of FIG. 19, since the target temperature of all the rooms is the same (21 ° C.), heat radiation is resumed in order from the room with the lowest room temperature at the SO end time. However, the target temperature may be different for each room. In this case, heat radiation is not always resumed in order from the room with the lowest room temperature at the SO end time. This is because the difference between the target temperature and the room temperature acquired in step S611 is calculated for each room, and the heat radiation resumption order is determined so that heat radiation is resumed in order from the heating device in the room where the difference is large.

Next, the heating system control unit 214 determines the heat radiation amount per unit time of the heating device in each room (S613). The method for determining the amount of heat radiation per unit time is not particularly limited. For example, the time from the restart of heat radiation until the target temperature is reached may be the same in all rooms (5 minutes in the example of FIG. 19). . That is, the heating system control unit 214 sets a relatively large amount of heat released per unit time in a room where the difference between the room temperature and the target temperature at the SO end time is large, and the difference between the room temperature and the target temperature at the SO end time What is necessary is just to set the heat dissipation amount per unit time of a small room relatively small. In this example of FIG. 19, the heat radiation amount per unit time of the heating device A3 is set to be the largest, and the heat radiation amount per unit time of the heating device B2 is set to the smallest.

Next, the heating system control unit 214 determines the heat radiation restart time of the heating device in each room (S614). It is desirable that the heat release restart time of each heating device is determined so that the plurality of heating devices do not release heat simultaneously in the first mode. That is, the heating system control unit 214 resumes heat dissipation in the first mode when the room temperature of the room where the heating device that radiates heat in the first mode reaches the target temperature. As such, the heat release restart time for each heating device may be determined.

In the example of FIG. 19, heat dissipation is resumed in the heating device A3 at 9 o'clock of the SO end time, heat dissipation is resumed in the heating device A2 at 9:05 when the room A3 reaches the target temperature, and the room A2 reaches the target temperature. The heat radiation restart time of each heating device is determined so that heat radiation is resumed at the heating device B2 at 10 minutes. In addition, the heating device control unit 204 in the rooms A2 and B2 sets each heating device so as to maintain the room temperature at the SO end time from the end of the SO time until the radiation of the rooms A2 and B2 is resumed. Control.

Next, returning to FIG. 17A again, the heating system control unit 214 notifies the determined operating conditions to the heating device control unit 204 of each room (S604). Specifically, the heating system control unit 214 may notify the heating device control unit 204 of each room of the heat release start time and the heat release amount per unit time as operating conditions.

Next, returning to FIG. 18, the heating device control unit 204 of each room obtains the operating conditions from the heating system control unit 214 (S706). Then, the heating device control unit 204 in each room opens the valve 202 in accordance with the acquired operating condition, that is, resumes heat radiation from the radiator 201 (S707).

In the example of FIG. 19, the heating device control unit 204 in the room A3 causes the heating device A3 to resume heat radiation in the first mode at 9:00, which is the SO end time. Moreover, the heating device control unit 204 of the rooms A2 and B2 may cause the heating devices A2 and B2 to resume heat radiation in the second mode in order to maintain the current room temperatures of the rooms A2 and B2, respectively. As a result, the room temperature of the room A3 gradually increases, and the room temperatures of the rooms A2 and B2 are kept constant.

Next, when the room temperature of the room A3 reaches the target temperature at 9:05, the heating device control unit 204 of the room A3 switches the operation mode of the heating device A3 from the first mode to the second mode. As a result, the room temperature of the subsequent room A3 is kept at the target temperature. At the same time, the heating device control unit 204 in the room A2 switches the operation mode of the heating device A2 from the second mode to the first mode. As a result, the room temperature of the room A2 gradually increases.

Next, when the room temperature of the room A2 reaches the target temperature at 9:10, the heating device control unit 204 of the room A2 switches the operation mode of the heating device A2 from the first mode to the second mode. As a result, the room temperature of the subsequent room A2 is kept at the target temperature. At the same time, the heating device control unit 204 in the room B2 switches the operation mode of the heating device B2 from the second mode to the first mode. As a result, the room temperature of the room B2 gradually increases.

When the room temperature of the room B2 reaches the target temperature at 9:15, the heating device control unit 204 of the room B2 switches the operation mode of the heating device B2 from the first mode to the second mode. As a result, the room temperature of the subsequent room B2 is kept at the target temperature. Further, the total amount of heat released thereafter returns to the level before the SO start time.

As mentioned above, the peak of the heat consumption can be leveled by stopping all the heating devices in the SO time zone. In addition, since all the heating devices are not restarted at the same time at the SO end time, it is possible to prevent the peak of the total heat consumption from occurring immediately after the SO end.

Furthermore, since the room heating devices in the room where the difference between the room temperature and the target temperature at the SO end time is large are restarted in order, the comfort of each room can be leveled. Here, the “room where the difference between the room temperature and the target temperature at the SO end time is large” refers to a room where the room temperature decrease rate is fast. In other words, as described above, the room heating devices are restarted in order from the room temperature at which the sensible temperature is low (comfort is low).
