<p>A refrigerant circuit is formed by connecting by means of refrigerant piping a compressor (2), a condenser (3), a first supercooling device (6) that supercools a refrigerant by exchanging heat with the air, a second supercooling device (8) that performs a heat exchange between refrigerant streams that have been branched by a branch pipe (14), thereby supercooling one of the refrigerant streams, a flow rate adjustment device (12) that adjusts the flow rate of the other of the branched refrigerant streams, and then passes this refrigerant through the second supercooling device, a bypass passage (11) through which the refrigerant that has passed through the flow rate adjustment device (12) and the second supercooling device (8) flows, an expansion valve (9), and an evaporator (10). In addition, a control device (20) is provided that controls, on the basis of the air temperature, the amount of heat exchanged in the first supercooling device (6) and the amount of heat exchanged in the second supercooling device (8).</p> |
