<p>A refrigerating apparatus includes: a first branch pipe (34) used for branching a liquid refrigerant inside of a liquid pipe (33) and provided with a subcooling expansion valve (29); a subcooling heat exchanger (28) provided along the liquid pipe (33) and subcooling a liquid refrigerant inside of the liquid pipe (33) with a branched refrigerant flowing thereinto from the first branch pipe (34); and a refrigerant circuit (10) for injecting the branched refrigerant after the subcooling into an intermediate-pressure compression chamber of a compressor (21a, 21b, 21 c). A controller (80) determines a target temperature of the liquid refrigerant inside of the liquid pipe (33) after the subcooling according to a cooling load in an inside-cabinet heat exchanger (53) and controls the opening of the subcooling expansion valve (29) such that the temperature detected by a liquid temperature sensor (68) becomes the target temperature.</p> |
