Abstract: A heat source unit control system prevents a heat-pump heat source from operating at a maximum outlet temperature of heated water, which is caused by an unnecessarily high temperature of circulating water. A return-water temperature sensor S(in) detects a temperature Tm(in) of circulating water which flows through a forward channel 610 in a circulation circuit 600 to return back to a heat-pump heat source 100. A tank-water temperature sensor S(t) detects a temperature Tt of water stored in a hot water storage tank 200. A controller 500 controls the operating frequency of a compressor installed in the heat-pump heat source 100 so that Tm(in) - Tt = ΔTb, where Tm(in) - Tt denotes a temperature difference between the temperature Tm(in) of the circulating water detected by the return-water temperature sensor S(in) and the temperature Tt of the water in the tank detected by the tank-water temperature sensor S(t), and ΔTb denotes a set value. A heat source unit control system prevents a heat-pump heat source from operating at a maximum outlet temperature of heated water, which is caused by an unnecessarily high temperature of circulating water.

Abstract: Provided is a temperature-adjusting fluid supply apparatus that causes a fluid for temperature adjustment to be circulated between a heat exchanger that transfers heat supplied from a refrigerant to the fluid, and an object to be adjusted for temperature that uses the heat of the fluid, the temperature-adjusting fluid supply apparatus being able to prevent the fluid from freezing. A temperature-adjusting fluid supply apparatus is provided with a heat exchanger that transfers heat supplied from a refrigerant to a fluid for temperature adjustment, a supply tube through which the fluid flows from the heat exchanger toward an object to be adjusted for temperature, a return tube through which the fluid returning from the object to be adjusted for temperature flows, a flow rate adjustable pump, a flow sensor, a flow switch, a temperature sensor, and a control part. The flow switch, in comparison with the flow sensor, is able to detect flow rate changes with coarser precision, and is less affected in detection accuracy by viscosity changes in the fluid. On the basis of the temperature of the fluid detected by the temperature sensor, the control part switches between pump control based on the detection results of the flow sensor and pump control based on the detection results of the flow switch. Provided is a temperature-adjusting fluid supply apparatus that causes a fluid for temperature adjustment to be circulated between a heat exchanger that transfers heat supplied from a refrigerant to the fluid, and an object to be adjusted for temperature that uses the heat of ...more ...less
