PROBLEM TO BE SOLVED: To make proper control of freezer's performance easy and thereby improve usability of the freezer.SOLUTION: A first compressor part (111) and a second compressor part (112) are provided in a refrigerant circuit (11) of a freezer (10). The first compressor part (111) communicates with a first utilization side heat exchanger (74) through a first suction pipeline (32). The second compressor part (112) communicates with a second utilization side heat exchanger (84) or a heat source side heat exchanger (26) through a second suction pipeline (34). The first suction pipeline (32) and the second suction pipeline (34) are connected with each other through a connection pipeline (47). A control valve (48) which can vary the degree of an opening is provided at the connection pipeline (47). |
