It is about how to check the system.

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. These 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 by using a pump. It is supplied by each household in the house. The hot water supplied to each household transfers thermal energy to each household, is cooled, is returned to a heat exchanger through a water return pipe, and heated again.

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

When an apartment house with a district heating system is completed and moves in, the construction entity or facility companies check whether the heating system is operating normally. The current heating system inspection is carried out in a way that workers directly visit each household. That is, many workers enter each household one by one, operate the heating device of each household, measure the indoor temperature, or visually determine whether there is an abnormality.

However, this conventional method requires a lot of manpower, so labor costs are high, and problems such as damage to facilities due to the carelessness of workers are likely to occur. Will follow. In addition, since the conventional inspection method is performed by a worker, there is a risk that the worker may not accurately recognize the heating abnormal state of the household, and subjective judgment of the worker must be intervened, making it difficult to objectively determine the correct state.

In addition, the integrated control unit 300 may communicate with the personal terminal 700 of the manager through the communication unit 500 to transmit various types of information for offline inspection or management to the personal terminal 700. The information provided by the integrated control unit 300 to the personal terminal 700 may include the heating operation status of each household, the location of the household with an abnormality in the heating operation, and the location of the heating zone in the household with an abnormality in the heating operation. have. Such information obtained by the integrated control unit 300 may be output through the display 550.

As shown in FIG. 4, the method of inspecting the district heating type apartment heating system according to an embodiment of the present invention includes a step of assigning a unique identification number for each household (S11), and a maximum opening amount of a household flow control valve for each household. Or setting the same opening rate (S12), 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 each household Acquiring the indoor temperature and the return temperature of (S15), comparing the indoor temperature and the return temperature of each household with the heating target temperature and the return reference temperature range (S16), and determining whether each household is abnormal. (S17) is included.

First, the step of assigning a unique identification number for each generation (S11) is a step in which the integrated control unit 300 receives a household identification number for each of the plurality of households 120. In this step, the integrated control unit 300 may receive a household identification number for each of the plurality of households 120, as well as 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 (S13) of setting the heating target temperature of each household equally, the integrated control unit 300 controls the household heating control unit 230 of each of the plurality of households 120 to control each of the plurality of households 120. This is the step of setting the heating target temperature equally. In this step, heating target temperatures of each of the heating zones 125 provided in each household 120 may be set to be the same.

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. When 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, an appropriate heating target temperature is set, and an appropriate heating time can be determined accordingly. For example, if the outside air temperature is 10℃ and the heating target 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 (S15) of acquiring the indoor temperature and the water exchange temperature of each household, after heating each household 120 for a set time, the integrated control unit 300 performs the indoor temperature detector ( This is a step of acquiring the room temperature and the return water temperature from the 222) and the return water temperature detector 228. In this step, the indoor temperature of each of the heating zones 125 of each household 120 and the return temperature of hot water returned through the heating pipes 214 respectively disposed in the heating zones 125 of each household 120 May be provided to the integrated control unit 300.

Next, the step (S16) of comparing the indoor temperature and the return temperature of each household with the heating target temperature and the return reference temperature range (S16) is a pre-set heating target for the indoor temperature obtained by the integrated control unit 300 from each of the plurality of households 120. This is a step of comparing the temperature with the water exchange temperature obtained from each of the plurality of households 120 with a preset water exchange reference temperature range. In this step, the integrated control unit 300 determines whether the indoor temperature of each household 120 has reached the heating target temperature or is less than the heating target temperature, and the return temperature of the hot water returned by heating each household 120 is It is determined whether it is within the range of the reference temperature of the exchange or less than the reference temperature of the exchange.

The indoor temperature and the water return temperature are the lowest indoor temperature among the indoor temperatures of each of the plurality of heating zones 125 provided in each household 120, the average temperature of each of the plurality of heating zones 125, and a plurality of The highest indoor temperature among the indoor temperatures of each of the heating zones 125, the lowest return temperature among the return temperatures of each of the plurality of heating zones 125, and a return temperature obtained by averaging the return temperature of each of the plurality of heating zones 125. , Various temperatures capable of comparing the heating state of each household 120, such as the highest return temperature among the return temperatures of each of the plurality of heating zones 125, may be used.

In addition, in the step (S16) of comparing the indoor temperature and the water exchange temperature of each household with the target heating temperature and the water exchange reference temperature range (S16), the integrated control unit 300 determines the indoor temperature of each of the heating zones 125 provided in each household 120. It is determined whether or not the heating target temperature has been reached or is less than the heating target temperature. In addition, the integrated control unit 300 determines whether the return temperature of the hot water passing through the heating pipes 214 disposed in the heating zones 125 of each household 120 is within the return reference temperature range or less than the return reference temperature. do. Here, the water exchange reference temperature may be set in an appropriate range from the existing data. For example, when the hot water supply temperature is 50°C, the return water reference temperature may be set to 30 to 35°C.

Next, the step (S17) of determining whether each household is abnormal is from the result data of the step (S16) of the integrated control unit 300 comparing the indoor temperature and the return temperature of each household with the target heating temperature and the reference temperature range. This is the step of determining whether the heating state of each household 120 is normal or abnormal. In this step, the integrated control unit 300 divides the plurality of households 120 into a household that has reached the heating target temperature and a household that has not reached the heating target temperature, thereby finding a household having an abnormality in the heating state. That is, the integrated control unit 300 may determine a household whose indoor temperature has not reached the heating target temperature even after heating for a preset period of time as a household having an abnormality in the heating state.

More specifically, the integrated control unit 300 determines whether or not each household is abnormal, among the households that have not reached the heating target temperature, the households whose return temperature is within the reference temperature range and the household whose return temperature is less than the reference temperature range. The abnormal state can be judged differently. That is, the integrated control unit 300 determines that there is an environmental abnormality in a household whose indoor temperature is less than the heating target temperature and the return temperature is within the return reference temperature range. In addition, the integrated control unit 300 determines that there is a facility abnormality in a household whose indoor temperature is less than the heating target temperature and the return temperature is less than the return reference temperature range.

Here, the environmental abnormality refers to a case in which the household heating equipment 200 of each household does not have a problem in heating operation, but there is a problem other than the household heating equipment 200 such as an open window or door of the household. Environmental abnormalities are abnormal conditions that can be easily resolved through measures such as closing windows or doors. On the other hand, the facility abnormality indicates a case in which there is a problem with the household heating equipment 200 of each household. Problems such as an abnormal operation of various valves of the household heating facility 200, or a failure of the hot water supplied to the household to flow normally due to an abnormality of a heating pipe may become a facility abnormality. Equipment abnormalities can be solved by the worker checking and repairing the household heating equipment 200.

As described above, the heating conditions according to the indoor temperature and the return temperature of each household can be summarized as shown in the table below.

In the present embodiment, each household 120 includes a plurality of heating zones 125, and even in the same household, the heating state of each heating zone 125 may be different. For example, a window of a specific heating zone 125 among the plurality of heating zones 125 may be open, or there may be a problem with the flow of hot water in the specific heating zone 125.

Therefore, in the step (S17) of determining whether each household is abnormal, the integrated control unit 300 controls each heating zone 125 according to the indoor temperature and the return temperature of the heating zones 125 of each household 120. Also, the heating state can be classified into a normal state, an environmental abnormal state, and an equipment abnormal state.
