が大幅に低減される。(E) Function Since the capacity of the heat source unit is selected according to the total maximum load of a plurality of radiators, there is enough room when the load of each radiator is stable. Further, the heat radiation amount of each radiator is determined by the temperature difference between the inlet and the outlet of the radiator and the flow rate. If the inlet temperature is assumed to be constant, it is determined by the outlet temperature and the flow rate. When the flow rate is constant, the room temperature is low,
When the load is large, the outlet temperature is low, the room temperature is high, and when 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 when the hot water temperature on the outlet side is high, the flow rate is adjusted so that the flow rate decreases so that the valve opening degree of each radiator is adjusted. At the start of operation of each radiator, a large flow rate can be obtained, the ability of the radiator can be fully exploited and the rise of the room temperature can be improved, and the flow rate can be reduced when stable, the amount of wasted heat dissipation is less, and the efficiency is higher. Good heating can be done. Moreover,
Since the pump flow rate is controlled based on the valve openings of the plurality of flow control valves, the pump flow rate is reduced when the overall load is small, so that pump power is saved and heat radiation loss is significantly reduced.
