Description

District heating method optimal heating method for apartment houses{DISTRICT HEATING TYPE OPTIMUM HEATING METHOD FOR APARTMENT BUILDINGS}

The present invention relates to an optimal heating method for a district heating type apartment house, and more specifically, the total flow rate supplied to the apartment house is differentially distributed to each household according to the heating environment of each household of the apartment house, thereby distributing the entire apartment house. It relates to the optimal heating method of district heating type apartment houses that can be heated efficiently.

In general, district heating does not install individual heat production facilities in apartments, business, commercial, and public buildings, but supplies heat (medium hot water) produced in large-scale heat production facilities such as combined heat and power plants to large-scale dwellings and buildings collectively. It is an urban infrastructure. Such district heating systems can be largely divided into heat production facilities, heat transport facilities, and heat use facilities.

In the case of the apartment heating system using the district heating method, the heat energy produced in the heat production facility is supplied through the heat transport facility to produce hot water required for heating through a heat exchanger, and the hot water heated in the heat exchanger is shared using a pump. It will be supplied for each household in the house. The hot water supplied to each household transfers heat energy to each household, is cooled, and then returned to a heat exchanger through a water return pipe and heated.

The district heating type apartment heating system has an energy saving effect by improving energy use efficiency compared to other heating systems, is convenient because it can use heat 24 hours a year, and maintains a constant indoor temperature for each household at all times. It has the advantage of maintaining a comfortable residential environment and creating a clean urban environment by reducing pollutant emissions.

Apartment houses with district heating type heating systems are supplied with hot water at a preset flow rate in proportion to the number of households. Typically, hot water supplied to apartment houses is distributed and supplied to each household at a predetermined flow rate in consideration of the area ratio for each household. For example, if the total flow rate of hot water supplied to an apartment house consisting of 100 households of the same area is 1000 LPM, the apartment heating system is designed so that the hot water is distributed by 10 LPM to each household. In addition, when the area of each household is different, the apartment heating system is designed so that hot water is distributed to each household in consideration of the area ratio for each household.

However, since each household in an apartment house has a different heating environment, it is difficult to obtain the same heating effect in each household even if a pre-set hot water is supplied.

For example, in winter, households located on the bottom or top floor of an apartment house are more likely to lose heat to the outside air than households located on the middle floor.Therefore, a relatively large amount of hot water must be supplied to raise the indoor temperature to the target heating temperature. do. In addition, even if it is located on the same floor, a household with a large area in contact with the outer wall is more likely to lose heat to the outside air than a household with a small area in contact with the outer wall.Therefore, the heating time is inevitable to increase the indoor temperature to the heating target temperature. This difference in heating environment may appear in the same household depending on the location of the heating zone.

As described above, in the conventional district heating system, even though the heating environment for each household is different, hot water is uniformly distributed to each household or distributed according to the area ratio for each household, so heating is inefficient. .

It shows a part of the district heating system apartment heating system shown, Figure 3 shows the household heating equipment of the district heating system apartment heating system shown in FIG.

The optimal heating method for a district heating-type apartment house according to an embodiment of the present invention is the optimum flow rate required for each household 120 to operate effectively according to the heating environment of each household 120 constituting the apartment house 100. By finding and supplying the flow rate of hot water supplied to the entire apartment house 100 to each household 120, it is possible to overcome the difference in heating performance according to the difference in heating environment for each household.

That is, by using the optimal heating method of a district heating type apartment house according to an embodiment of the present invention, the maximum flow rate of hot water that can be supplied is relatively reduced for households with a good heating environment, and for households with a relatively poor heating environment. The furnace can relatively increase the maximum flow rate of hot water that can be supplied, thereby improving the heating operation performance of households with relatively poor heating environments. In addition, by differentially distributing and supplying the flow rate of hot water to each household 120 according to the heating environment for each household, the entire apartment house 100 can be heated more efficiently.

As shown in Fig. 1, the multi-family house 100 referred to in the present invention is an independent residential life for each household 120 while several households use all or part of the walls, corridors, stairs, and other facilities of the building. It is defined as a house with this possible structure, and such apartments can include apartments, row houses, multi-family houses, and dormitories.

As shown, the district heating system apartment heating system installed in the apartment house 100 includes a plurality of household heating facilities 200 respectively installed in the plurality of households 120 constituting the apartment house 100, It includes an integrated control unit 300 for integrated control of a plurality of household heating equipment 200.

The integrated control unit 300 may be installed in the machine room 400 so that an administrator can manage it. In addition to the integrated control unit 300, the machine room 400 includes a heat exchanger 450 that generates hot water required for heating by exchanging heat with thermal energy supplied from a heat production facility, and a communication unit 500 for communication between the integrated control unit 300 and , A pump 600 may be installed to pressurize the hot water heated by the heat exchanger 450 to each household 120. The heat exchanger 450 may heat hot water circulating in each household 120 to a temperature of approximately 50° C. using heat energy supplied from a heat production facility, like a conventional district heating system. The integrated control unit 300 may communicate with the plurality of household heating facilities 200 in a wired or wireless manner through the communication unit 500.

As shown in FIGS. 2 and 3, the household heating facility 200 is installed in each household 120 to receive hot water heated by the heat exchanger 450 to heat each household 120. In the present embodiment, each household 120 will be described as having a plurality of heating zones 125 requiring heating.

The household heating facility 200 includes a water supply pipe 210 for supplying hot water to the household 120, a water supply header 212 connected to the water supply pipe 210, and a plurality of water supply headers 212 supplied with hot water. A heating pipe 214, a water return header 218 through which hot water passing through the plurality of heating pipes 214 flows into, and a water return pipe 216 connected to the water return header 218, and a water return pipe 216 It includes a household flow control valve 220 for adjusting the flow rate of hot water and a household heating control unit 230 for heating control of the household 120. The water supply header 212 distributes the hot water supplied through the water supply pipe 210 to a plurality of heating pipes 214, and the water return header 218 collects the hot water that has passed through the plurality of heating pipes 214 and collects the water return pipe 216 ).

The plurality of heating pipes 214 are buried in each heating zone 125 to supply hot water to the plurality of heating zones 125 provided in each household, and the hot water flows through the heating pipe 214 to thereby provide a heating zone ( 125). Here, the heating zone 125 may be a room, a living room, or a kitchen provided in each household 120. In each heating zone 125, a room temperature detector 222 for measuring the room temperature is installed. The room temperature detector 222 may detect the room temperature of each heating zone 125 and transmit a detection signal to the household heating control unit 230 or the integrated control unit 300.

A hot water control valve 224 is installed between the water supply header 212 and the heating zone 125. The hot water control valve 224 can be manually operated by the user, and the user manipulates the hot water control valve 224 to regulate the flow of hot water through the heating pipe 214 or supplied to the heating pipe 214. You can manually adjust the flow rate of hot water.

Between the heating zone 125 and the water return header 218, a heating pipe flow control valve 226 and a water return temperature detector 228 are installed. The heating pipe flow control valve 226 serves to adjust the flow rate of hot water flowing through the heating pipe 214. The heating pipe flow rate control valve 226 is controlled by the household heating control unit 230 or the integrated control unit 300 so that the opening amount thereof can be adjusted. The flow rate of hot water supplied to each heating zone 125 through the heating pipe 214 can be adjusted according to the opening amount of the heating pipe flow control valve 226. That is, when the opening amount of the heating pipe flow control valve 226 increases, the flow rate of hot water flowing along the heating pipe 214 increases, and when the opening amount of the heating pipe flow control valve 226 decreases, the heating pipe 214 is closed. The flow rate of hot water passing through it is reduced. The household heating control unit 230 or the integrated control unit 300 effectively heats the heating zone 125 by controlling the heating pipe flow control valve 226 according to the heating target temperature, the room temperature, and the return temperature of the heating zone 125. Hot water having an optimum flow rate required for this can be made to flow to the corresponding heating pipe 214. The water return temperature detector 228 may heat the heating zone 125 and detect the temperature of hot water to be returned, and transmit the detection signal to the household heating control unit 230 or the integrated control unit 300.

The household flow control valve 220 may adjust the flow rate of hot water supplied to the household 120 by changing the flow rate of the hot water returned through the water return pipe 216. The household flow control valve 220 is controlled by the household heating control unit 230 or the integrated control unit 300 so that the opening amount thereof may be adjusted. The flow rate of hot water returned to the return pipe 216 can be adjusted according to the opening amount of the household flow control valve 220, and as a result, the flow rate of the hot water supplied through the water supply pipe 210 can be adjusted. That is, when the opening amount of the household flow control valve 220 increases, the flow rate of hot water supplied to the household 120 increases, and when the opening amount of the household flow control valve 220 decreases, the flow rate of hot water supplied to the household 120 Will decrease. The household flow control valve 220 is controlled according to the heating load, the room temperature, the return temperature, the pressure of hot water, etc., so that the hot water of the optimum flow rate necessary for effectively heating the household 120 can be supplied to the household 120. .

The household heating controller 230 may control the heating operation of the household 120 by controlling the plurality of heating pipe flow control valves 226 and the household flow control valve 220. The household heating control unit 230 includes a temperature controller 232 installed in each heating zone 125 and a main controller 234.

The temperature controller 232 is operated by a user, and a heating tube installed in the heating zone 125 so that the indoor temperature of the heating zone 125 reaches the heating target temperature according to the heating target temperature set by the user. It is possible to control the heating pipe flow control valve 226 and the household flow control valve 220 corresponding to 214. The temperature controller 232 may periodically receive a detection signal from the room temperature detector 222 installed in the heating zone 125, and when the room temperature detected by the room temperature detector 222 reaches the heating target temperature By controlling the heating pipe flow control valve 226 or the household flow control valve 220, the flow rate of hot water supplied to the heating zone 125 may be reduced or the supplied hot water may be cut off. Further, the temperature controller 232 receives a detection signal from the indoor temperature detector 222 and controls the heating pipe flow control valve 226 or the household flow control valve 220 when the indoor temperature falls below the target heating temperature to control the corresponding heating zone. With (125), hot water can be supplied again or the flow rate of supplied hot water can be increased.

The main controller 234 is a plurality of heating units so that hot water having an optimum flow rate required to effectively heat the plurality of heating zones 125 according to a heating target temperature, indoor temperature, and return temperature, etc. can be supplied to the plurality of heating zones 125. The pipe flow control valve 226 and the household flow control valve 220 can be controlled in real time. The main controller 234 is a heating corresponding to the heating tube 214 installed in the heating zone 125 so that the indoor temperature of the heating zone 125 reaches the heating target temperature according to the heating target temperature set by the user. It is possible to control the pipe flow control valve 226 and the household flow control valve 220. The user may set a heating target temperature for a specific heating zone 125 through the main controller 234. In addition, the main controller 234 receives input signals from the plurality of temperature controllers 232 and includes a plurality of heating pipe flow control valves 226 and households so that the indoor temperature of each heating zone 125 reaches the heating target temperature. The flow control valve 220 can be controlled.

The integrated control unit 300 communicates with the household heating control unit 230 of each household heating facility 200 to receive various information necessary for heating operation, such as a heating target temperature, an indoor temperature, and a return temperature of each household 120. In addition, the integrated control unit 300 compares the indoor temperature obtained from each of the plurality of households with a preset heating target temperature, and compares the return temperature obtained from each of the plurality of households with a preset water return reference temperature range, so that the heating operation state of each household Can be checked, and the optimum hot water flow rate required to effectively heat each household can be calculated according to the heating operation status of each household. More specific functions of the integrated control unit 300 will be described later. In addition, the integrated control unit 300 may remotely control the heating pipe flow control valves 226 and the household flow control valve 220 of each household 120 by communicating with the household heating control unit 230.

As shown in Figure 4, the optimal heating method of the district heating type apartment house according to an embodiment of the present invention, the step of assigning a unique identification number for each household (S11), and the maximum opening amount or The step of setting the same opening ratio (S12), the step of setting the heating target temperature of each household equally (S13), heating each household for the same time at the set hot water flow rate (S14), and It includes a step of acquiring the indoor temperature (S15), a step of comparing the indoor temperature of each household with a target heating temperature (S16), and a step of adjusting the hot water supply flow rate of each household (S17).

First, the step (S11) of assigning a unique identification number for each generation is a step in which the integrated control unit 300 receives a household identification number for each of the plurality of generations 120. In this step, the integrated control unit 300 may receive a household identification number for each of the plurality of households 120 and a household heating zone identification number for each of the heating zones 125 of each household 120.

Next, the step (S12) of setting the household flow control valve of each household to the maximum opening amount or the same opening ratio, the integrated control unit 300 sets the maximum opening amount or the same amount of the flow control valve 220 of each household of a plurality of households. This is the step of setting the opening ratio. In this step, the household flow rate control valve 220 of each household 120 is adjusted to the maximum opening amount or the same opening ratio, so that each household 120 receives the hot water supplied from the heat exchanger 450 at the maximum flow rate or the same ratio. It becomes the same environment that can be supplied with the flow rate of.

Next, in the step of setting the heating target temperature of each household equally (S13), the integrated control unit 300 controls the heating control unit 230 of each of the plurality of households to control the heating target temperature of each of the plurality of households 120. This is the step of setting the same. In this step, the heating target temperature of each of the heating zones 125 provided in each household 120 may be set equally.

Next, heating each household at a set hot water flow rate for the same time (S14) is a step of heating each household 120 by supplying hot water having a preset flow rate to each of the plurality of households 120 for a preset time. . For example, when a plurality of households have the same area, the flow rate supplied to each of the plurality of households may be set equally, and if a plurality of households have different areas, the total hot water supply flow rate and the plurality It is possible to set the flow rate supplied to each of the plurality of households in consideration of the area ratio of each of the households. In addition, when the target heating temperature is determined by knowing the area, indoor temperature, and outdoor temperature of the household 120, the time required to raise the indoor temperature of the household 120 to the heating target temperature at a preset flow rate can be estimated from the existing data. . Therefore, in this step, the outside air temperature at the time of heating is considered to set an appropriate heating target temperature, and an appropriate heating time can be determined accordingly. For example, if the outside temperature is 10℃ and the target heating temperature is 25℃, the time required to heat a household with a normal heating environment to the heating target temperature by supplying hot water to each household at a set flow rate may be 3 hours. . In addition, when the outside temperature is -5°C, the time required for heating a household with a normal heating environment to the heating target temperature may increase to 6 hours.

Next, in the step of acquiring the indoor temperature of each household (S15), after heating each household 120 for a set time, the integrated control unit 300 from the indoor temperature detector 222 of each of the plurality of households 120 This is the step of obtaining the indoor temperature. In this step, the heating target temperature of each of the heating zones 125 of each household 120 may be provided to the integrated control unit 300.

Next, the step of comparing the indoor temperature of each household with the target heating temperature (S16) is a step in which the integrated control unit 300 compares the indoor temperature obtained from each of the plurality of households 120 with a preset heating target temperature.

In this step, the integrated control unit 300 may compare the lowest indoor temperature among the indoor temperatures of each of the plurality of heating zones 125 provided in each household 120 with the target heating temperature. In addition, the indoor temperature compared with the heating target temperature is the average temperature of each of the plurality of heating zones 125, the highest indoor temperature among the indoor temperatures of each of the plurality of heating zones 125, etc. A variety of temperatures for comparing the heating conditions of 120) can be used. In addition, in the step (S16) of comparing the indoor temperature of each household with the target heating temperature, the integrated control unit 300 determines whether the indoor temperature of each of the heating zones 125 provided in each household 120 is higher than or equal to the heating target temperature, It can be determined whether it is below the heating target temperature.

Even if hot water of a preset flow rate is supplied to each household 120 of the apartment house 100 for the same time, each household 120 has a different heating environment, so it is difficult for each household 120 to obtain the same heating effect. In other words, households with a relatively good heating environment and households with a relatively poor heating environment are classified according to the number of floors and orientations of the household, and the households with a relatively good heating environment set the indoor temperature to the target heating temperature within a relatively short time. Can be reached, and the heating environment is relatively poor, the time for the indoor temperature to reach the heating target temperature becomes longer.

For example, as shown in FIG. 1, the household 120 located on the lowest or the highest floor of the apartment 100 is more likely to lose heat to the outside air in winter compared to the household 120 located on the middle floor, so the indoor temperature In order to increase the heating temperature to the target temperature, a relatively large amount of hot water must be supplied. In addition, as shown in FIG. 5, even if it is located on the same floor, the household 120 having a large area in contact with the outer wall 110 is more likely to lose heat to the outside air than the household 120 having a small area in contact with the outer wall 110. In order to increase the indoor temperature to the heating target temperature, the heating time has to be lengthened.

The integrated control unit 300 acquires the indoor temperature from each of the plurality of households 120 after a predetermined period of time has elapsed since the start of heating, so that the households having a good heating environment among the households 120 constituting the apartment house 100 and, Households with poor heating conditions can be identified.

Next, the step of adjusting the hot water supply flow rate of each household (S17) is a household flow control valve provided in each of the plurality of households 120 according to the indoor temperature obtained by the integrated control unit 300 from each of the plurality of households 120 This is the step of adjusting the opening degree of (220). In this step, the integrated control unit 300 is a household flow rate of each of the plurality of households 120 so that a relatively large amount of hot water can be supplied to a household that has not reached the heating target temperature during the heating time. The opening amount of the control valve 220 is adjusted. That is, the integrated control unit 300 reduces the opening amount of the household flow control valve 220 provided in a household having a good heating environment so that the maximum flow rate of hot water supplied to a household having a poor heating environment can be increased. In addition, it is possible to increase the opening amount of the household flow control valve 220 provided in a household having a poor heating environment.

Since the flow rate of hot water supplied to the entire apartment house 100 is determined, if the maximum flow rate of hot water supplied to some households is reduced, the maximum flow rate of hot water supplied to the other households increases.

For example, when two households are equally supplied with hot water at a maximum of 10 LPM, the opening amount of the household flow control valve 220 provided in the household can be reduced so that the hot water supply flow rate of one household is 8 LPM. have. In this case, the flow rate of hot water supply for other generations is relatively increased to 12LPM. With this principle, by setting the flow control valve 220 of a household having a good heating environment among the plurality of households 120 constituting the apartment house 100 so that the maximum hot water supply flow rate is reduced, the household having a poor heating environment The heating performance for the household can be improved by relatively increasing the maximum hot water supply flow rate.

In this embodiment, each household 120 includes a plurality of heating zones 125, and even in the same household, the heating environment of each heating zone 125 may be different. For example, a heating zone having a large area in contact with the outer wall 110 is more likely to take heat into the outside air than a heating zone having a small area in contact with the outer wall 110, so the heating environment is relatively poor, and the indoor temperature is the target for heating. To increase the temperature, the heating time is bound to be longer. In addition, the heating environment of each heating zone may be different according to the orientation of the heating zone.

Therefore, the integrated control unit 300 is a heating pipe corresponding to each heating zone 125 according to the room temperature obtained from each of the heating zones 125 of the household 120 in the step (S17) of adjusting the hot water supply flow rate of each household. The opening amount of the flow control valve 226 can be adjusted respectively. Since the heating pipe flow control valve 226 can change the flow rate of hot water supplied to the heating pipe 214 disposed in the heating zone 125, the heating zone is controlled by adjusting the opening amount of the heating pipe flow control valve 226. It is possible to adjust the flow rate of hot water supplied to (125). Since the maximum flow rate of hot water supplied to each household 120 is determined, one or more of the plurality of heating pipe flow control valves 226 provided in each household 120 decreases the opening amount of the heating pipe flow control valve 226 If controlled to be controlled, the maximum flow rate of hot water supplied to the heating zone 125 in which the flow rate is controlled by the other heating pipe flow control valve 226 can be relatively increased. Therefore, the integrated control unit 300 sets the heating pipe flow rate control valve 226 corresponding to the heating zone having a good heating environment among the heating zones 125 provided in each household 120 so that the maximum hot water supply flow rate is reduced, The heating performance for the heating zone can be improved by relatively increasing the maximum hot water supply flow rate in the heating zone where the heating environment is poor.

In the step of adjusting the hot water supply flow rate of each household (S17), for more efficient hot water distribution, the integrated control unit 300 determines the flow rate of hot water supplied to the households that have reached the heating target temperature before the set heating time. It can be adjusted differentially over time. That is, the integrated control unit 300 may control the household flow control valve 220 of each household 120 so that a relatively smaller amount of hot water is supplied to a household in which the heating target temperature is reached in a shorter time. Households with a short time to reach the heating target temperature can reach the heating target temperature with a relatively small flow rate of hot water. Therefore, by differentially reducing the flow rate of hot water supplied to each household according to the time reaching the heating target temperature, the overall heating efficiency of the apartment house 100 can be further improved. To this end, the integrated control unit 300 heats each household at a set hot water flow rate for the same time (S14) and then compares the indoor temperature of each household with the heating target temperature (S16), and before the step (S16), the plurality of households 120 The time to reach the heating target temperature can be obtained from.

The hot water flow rate control according to the time that the heating target temperature is reached may be equally applied to the heating zones 125 of the same household 120. That is, in the step (S17) of adjusting the hot water supply flow rate for each household, the integrated control unit 300 determines that the hot water flow rate supplied to the heating zone that has reached the heating target temperature before the heating time within the same household reaches the heating target temperature. It is possible to control the heating pipe flow control valve 226 provided in each household so as to be differentially adjusted according to time. By differentially reducing the flow rate of hot water supplied to each heating zone within the same household according to the time reaching the heating target temperature, the overall heating efficiency of the household can be further improved. To this end, the integrated control unit 300 heats each household for a set time at the same hot water flow rate (S14) and then compares the indoor temperature of each household with the heating target temperature (S16). The time to reach the heating target temperature may be obtained from the heating zones 125.

In addition, for more efficient hot water distribution in the step (S17) of adjusting the hot water supply flow rate of each household, the integrated control unit 300 differentiates the flow rate of hot water supplied to the households that have not reached the heating target temperature during the heating time according to the room temperature. Can be adjusted as an enemy. That is, the integrated control unit 300 is a flow control valve for each household of the plurality of households 120 so that a relatively larger amount of hot water can be supplied as the indoor temperature of the household that has not reached the heating target temperature during the heating time is lower. 220) can be adjusted. After heating for a predetermined period of time, it can be seen that the lower the indoor temperature is, the worse the heating environment is, and these households need more hot water. In this case, the method of reducing the opening amount of the household flow control valve 220 provided in the household that has reached the heating target temperature during the heating time, or in addition to the method, among the households that have not reached the heating target temperature during the heating time By adjusting the opening amount of the household flow control valve 220 provided in a household having a high indoor temperature, hot water with a higher flow rate can be supplied to a relatively poor household.

The hot water flow rate control according to the indoor temperature can be applied equally to the heating zones 125 of the same household 120. That is, in the step of adjusting the hot water supply flow rate of each household (S17), the integrated control unit 300 determines the heating pipe flow rate of each household so that the flow rate of hot water supplied to each heating zone within the same household is differentially adjusted according to the room temperature. Each of the control valves 226 may be controlled. By differentially adjusting the flow rate of hot water supplied to each heating zone within the same household according to the indoor temperature, the overall heating efficiency of the household can be further improved.

In the step of adjusting the hot water supply flow rate of each household (S17), after the opening amount of the household flow control valve 220 of each household 120 and the heating pipe flow control valves 226 of each household 120 is adjusted , Step of setting the heating target temperature of each household equally (S13), heating each household for the same time at a re-set hot water flow rate (S14), and obtaining the indoor temperature of each household (S15), and , Comparing the indoor temperature of each household with the target heating temperature (S16) and adjusting the hot water supply flow rate of each household (S17) may be repeatedly performed. Through this process, it is possible to find an optimum flow rate distributed and supplied to each household 120 so that the entire household 120 constituting the apartment house 100 can be heated most efficiently. And by setting the household heating equipment 200 of each household 120 so that hot water can be supplied to each household 120 at the determined optimal hot water flow rate, the overall heating efficiency of the apartment house 100 can be improved. have.

On the other hand, even after the tenant moves in, the heating environment of each household 120 may change at any time. For example, the heating environment of each household 120 and each heating zone 125 provided in each household 120 due to a change in the location of furniture or home appliances in each household 120 or a change in the interior of the room The heating environment of the can change. Therefore, by periodically repeating the same steps as described above to newly set the household heating equipment 200 of each household 120, the hot water supplied to each household 120 according to the heating environment change of each household 120 The optimum flow rate can be newly set.

As described above, according to the present invention, the maximum flow rate of hot water supplied to the households with good heating environment among the plurality of households 120 constituting the apartment 100 is reduced, and the maximum flow rate of hot water supplied to households with poor heating environment By differentially distributing the hot water supplied to the apartment house 100 to each household to increase, the entire apartment house 100 can be heated more efficiently.

In the above, although a preferred example has been described for the present invention, the scope of the present invention is not limited to the form described and illustrated above.

For example, in the drawing, the household heating control unit 230 of the household heating facility 200 is a temperature controller 232 installed in each heating zone 125, and a main controller 234 communicating with the plurality of temperature controllers 232. ), but in addition to this structure, the household heating control unit may be changed to various other structures capable of controlling the operation of the household heating facility 200 according to a user's manipulation or a control signal from the integrated control unit 300. I can.

Until now, the present invention has been shown and described in connection with a preferred embodiment for illustrating the principle of the present invention, but the present invention is not limited to the configuration and operation as shown and described as such. Rather, it will be well understood by those skilled in the art that a number of changes and modifications to the present invention can be made without departing from the spirit and scope of the appended claims.
