WIPO Patent Application WO/2013/038615

Kind Code:

A1

Abstract:

In an air conditioner (10) which is a refrigeration device, a degree-of-superheat controller (71) is provided for controlling the opening degree of an expansion valve (33) so that merged refrigerant having passed through a main heat exchange unit (50) and an auxiliary heat exchange unit (55) reaches a predetermined degree of superheat during evaporation operation of an outdoor heat exchanger (40). The air conditioner (10) is also provided with a flow rate adjustment valve (66) for adjusting the flow rate ratio of refrigerant that flows to the main heat exchange unit (50) and refrigerant that flows to the auxiliary heat exchange unit (55) during evaporation operation of the outdoor heat exchanger (40), and a flow rate ratio controller (72) for controlling the flow rate adjustment valve (66) so that the temperatures of refrigerant that has passed through the main heat exchange unit (50) and refrigerant that has passed through the auxiliary heat exchange unit (55) are substantially the same.
