快適で、効率の良い暖房を行うことかできる。(E) Since the capacity of the active heat source equipment is selected according to the total maximum load of multiple radiators, there is sufficient margin when the load of each radiator is stable. In addition, the amount of heat radiated by each radiator is determined by the temperature difference at the entrance and exit of the radiator and the flow rate, but if the input temperature is constant, it is determined by the outlet temperature and flow rate. , when the room temperature is low and the load is large, the outlet temperature is low, and when the room temperature is high and the load is small, the outlet temperature is high. Therefore, when the hot water temperature on the outlet side of the radiator is low, the flow rate is increased and the outlet By adjusting the valve opening of the flow control valve of each radiator so that the flow rate is lower when the hot water temperature on the side is high, a large flow rate can be obtained when each radiator starts operating, and the capacity of the radiator can be fully utilized. When the temperature is stable, the flow rate is reduced, allowing comfortable and efficient heating with less wasted heat radiation.

、装置全体の放熱損失を大幅に低減することができる。According to this embodiment, a flow control valve (13) whose valve opening degree is adjusted according to the hot water temperature on the outlet side of the radiator (4) is installed in series with the radiator (4). Since the room temperature is low at the beginning of operation of each radiator 4), the hot water temperature on the outlet side is set at the temperature set by the temperature setting device 16) (e.g. 60°C).
Since the opening of the flow rate control valve (13) is large, a large amount of hot water is circulated, and the room temperature rises quickly. In addition, as the room temperature rises, the hot water temperature on the outlet side of the radiator (4) increases, and the opening degree of the flow rate control valve (13) decreases, so when the temperature is stable, the circulation volume of each radiator (4) is reduced. This results in comfortable and efficient hot water heating with less wasted heat radiation. Moreover, the flow rate control valve 13)...
The total circulation flow rate required by the -C radiator (4) is calculated based on the valve opening degree of -C, and the pump flow rate is controlled according to the calculated value, so when the overall load is small, The pump flow rate is reduced, saving pump power and significantly reducing heat dissipation loss of the entire device.
