Abstract (en)
A heat source unit (10) for a refrigeration apparatus (1) includes a compressor (2) that performs multi-stage compression; a main heat exchanger (4, 45) that exchanges heat between a refrigerant and a fluid; and a sub-heat exchanger (7, 46, 47). The sub-heat exchanger (7, 46, 47) is disposed, independently from the main heat exchanger (4, 45), on an upstream side or a downstream side of the main heat exchanger (4, 45) in a flow of the fluid.
