Abstract (en)
A heat source system 1 of an embodiment includes an inlet-side pressure gauge 17 that is provided on an inlet side where water flows from a condensate return pipe into a water refrigerant heat-exchanger 9 and detects pressure of water flowing through the condensate return pipe on an upstream side of an inlet pump 10 for feeding water to the water refrigerant heat-exchanger 9, an outlet-side pressure gauge that is provided on an outlet side where water flows out from the water refrigerant heat-exchanger 9 to the water feed pipe 5 and detects pressure of water flowing through the water feed pipe 5, and a control device 16 for executing processing of controlling a bypass valve 2 provided in a bypass pipe 7 based on the difference between the pressure on the inlet side detected by the inlet-side pressure gauge 17 and the pressure on the outlet side detected by the outlet-side pressure gauge.
