However, the accompanying drawings are only one example for more specifically describing the technical idea of the present invention, and thus the technical idea of the present invention is not limited to the accompanying drawings.

1 is a schematic diagram showing a conventional apartment heating system.

In the conventional apartment heating system, the hot water supplied from the hot water boiler ignores the temperature of the outside air and supplies hot water above the predetermined temperature from the hot water boiler.

Since the supplied hot water is supplied through the heat exchanger, the hot water for heating is supplied at about 50 to 60 ℃ and the hot water for hot water is about 60 ℃, and unnecessary excess energy is consumed. Also, since the water temperature of the hot water for heating is high, intermittent heating is performed instead of continuous heating. .

At this time, the temperature of the hot water supplied from the hot water boiler is generally between 90 ~ 100 ℃ for district heating of cogeneration, and between 60 ~ 100 ℃ for hot water boiler by building.

The apartment heating system of the present invention adjusts the temperature of the hot water supplied from the hot water boiler according to the outside air temperature, and also controls the temperature of the hot water supplied from the heating heat exchanger and the hot water supply heat exchanger.

In the apartment heating system of the present invention, when the outside air temperature is 0 ~ -15 ℃, the water temperature of the hot water supplied from the hot water boiler 10 is 54 ~ 60 ℃, the water temperature of the hot water supplied via the heating heat exchanger (70) Is 35 to 40 ° C., and the water temperature of the hot water supplied through the hot water supply heat exchanger 60 is 46 to 50 ° C.

The hot water boiler 10 of the present invention may use a general hot water boiler or a heat pump, and any boiler may be used as long as it can supply hot water at a predetermined temperature by the water temperature controller 20.

The temperature of the water supplied to the hot water boiler 10 and the temperature of the heat exchanger 70 for heating according to the outside air temperature of the present invention and the return temperature of the hot water boiler 10 are shown in Table 1 below.

<Table 1> Example of hot water temperature according to outside temperature

                                                   (Unit: ℃)

Ambient temperature (high) Ambient temperature (low) Hot water boiler Heat exchanger for heating Hot water temperature Room temperature Supply temperature Return temperature 25 25 47 ~ 48 30 27.5 42 24 ~ 26 24 13 50 32 28.5 44 24 ~ 26 13 0 52 34 29 45 24 ~ 26 0 -5 54 35 30 46 24 ~ 26 -5 -10 56 36 30.5 47 24 ~ 26 -10 -14 58 38 31 48 24 ~ 26 -15 -15 60 40 32 50 25`27

As shown in Table 1 above, if the hot water is supplied by adjusting the temperature of hot water supplied from the hot water boiler 10 according to the height of the outside temperature of the day, a comfortable room temperature of 24 to 26 ° C can be obtained.

On the other hand, the water temperature according to the apartment heating system of the present invention can be represented by a graph as shown in FIG.

For example, when the outside temperature is at most -5 ℃, at least -10 ℃, the temperature of the hot water supply of the hot water boiler 10 56 ℃, the supply temperature of the heating heat exchanger 70 36 ℃, hot water temperature 47 ℃, room temperature 24 ~ 26 ℃.

The outside air temperature sensor 30 of the present invention is preferably a temperature sensor for transmitting the outside air temperature data as a digital signal, the outside air temperature sensor is installed in a place that can properly measure the outside air temperature outside the apartment heating demand 80 Do not let anyone other than the manager injure you. 3 to 5 outside temperature sensors can be installed as needed, in which case the average of the detected outside temperatures is used.

The water temperature controller 20 receiving the outside air temperature data from the outside air temperature sensor 30 enables electronic control and manual control, and is an electronic control system employing an embedded system, a PLC, or a computer with a small microprocessor. As a function of controlling the water temperature of the hot water boiler.
