Abstract (en)
[origin: EP3062041A1] It is an object of the present invention to provide a refrigeration apparatus that can prevent occurrence of liquid returning when a refrigerant circuit is equalized in pressure in activation. An air conditioning apparatus (1) includes a refrigerant circuit (2) in which a compressor (11) of a variable capacity type, an outdoor heat exchanger (13), a first electric expansion valve (14), a receiver (15), a second electric expansion valve (16) and an indoor heat exchanger (17) are sequentially connected. The air conditioning apparatus (1) includes a four-way switch valve (12) and a controller (5). The four-way switch valve (12) is configured to switch a flow direction of a refrigerant circulating through the refrigerant circuit (2). The controller (5) is configured to control an opened/closed state of the first electric expansion valve (14) and that of the second electric expansion valve (16). In activation of the air conditioning apparatus (1), the controller (5) is configured to determine which of the first electric expansion valve (14) and the second electric expansion valve (16) corresponds to a high pressure side electric valve located in a high pressure part of the refrigerant circuit (2) and is configured to fully open the high pressure side electric valve.
