A heat recovery refrigeration device (1) includes a compressor (21), a plurality of heat source side heat exchangers (24, 25), and a plurality of usage side heat exchangers (52a, 52b, 52c, 52d), and is able to perform heat recovery between the usage side heat exchangers by sending refrigerant from the usage side heat exchanger which functions as a radiator for refrigerant to the usage side heat exchanger which functions as an evaporator for refrigerant. Then, the plurality of heat source side heat exchangers (24, 25) have a first heat source side heat exchanger (24) and a second heat source side heat exchanger (25) which has a heat exchange capacity which is 1.8 times to 4.0 times of the first heat source side heat exchanger (24). |
