Document Type and Number:
WIPO Patent Application WO/2018/025382
Kind Code:
Disclosed is a heat source system that is provided with a heat source unit that heats and cools a fluid, and a control device that controls the heat source unit. The heat source unit is provided with: a refrigerant circuit wherein a compressor, refrigerant flow channel switch device, air-side heat exchanger, decompression device, and heat medium-side heat exchanger are connected via refrigerant piping; fluid piping, in which the fluid to be subjected to heat exchange with a refrigerant of the refrigerant circuit by means of the heat medium-side heat exchanger flows; a fluid pump, which is provided to the fluid piping, and which supplies the fluid to the heat medium-side heat exchanger; and an inlet temperature sensor that measures the temperature of the fluid flowing into the heat medium-side heat exchanger. The control device is provided with an operation control means that controls the fluid pump so that when defrosting operations, in which the air-side heat exchanger becomes a condenser, and the heat medium-side heat exchanger becomes an evaporator, are being performed, the flow rate of the fluid to be supplied to the heat medium-side heat exchanger changes in accordance with the fluid temperature measured by the inlet temperature sensor.
