Abstract (en)
Provided is a heat source device that can reduce the diameter of a pipe used for supplying a cooling refrigerant to be guided to the intake side of a compressor. A chiller (1) includes: a compressor (3) that compresses a refrigerant; a water heat exchanger (5) configured to perform heat exchange between a refrigerant and water; a first expansion valve (6) that expands a refrigerant; an air heat exchanger (9) that performs heat exchange between a refrigerant and air; and a liquid bypass pipe (20) whose upstream end is connected between the water heat exchanger (5) and the first expansion valve (6) and that guides a liquid refrigerant to an intake side of the compressor (3). A second expansion valve (8) is provided on the air heat exchanger (9) side, and a receiver (7) is provided between the first expansion valve (6) and the second expansion valve (8).
