<p>A first compressor (111) and a second compressor (112) are provided in a refrigeration circuit (11) of a refrigerating device (10). The first compressor (111) links to a first use-side heat exchanger (74) via a first intake piping (32). The second compressor (112) links to a second use-side heat exchanger (84) or a heat source side heat exchanger (26) via a second intake pipe (34). The first intake pipe (32) and the second intake pipe (34) are joined via a joining pipe (47). A control valve (48) with a variable opening is provided in the joining pipe (47). The cooling capacity of the refrigerating device (10) is easily controlled by adjusting the opening of the control valve (48).</p> |
