Title:
REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/179803
Kind Code:
A1
Abstract:
A refrigeration device is configured in such a manner that an increase in the size of a heat exchanger for injection is minimized and in such a manner that the function of reducing the discharge temperature of a compressor is ensured. An air conditioning device (10) using an R32 refrigerant is provided with: a compressor (20); an indoor heat exchanger (50); an outdoor expansion valve (41); an outdoor heat exchanger (30); a branch pipe (62); an electric valve (63) and a heat exchanger (64), which are used for injection; a high-pressure receiver (80); and the like. The heat exchanger (64) allows the exchange of heat between a refrigerant which flows though a main refrigerant flow passage (11a) and a refrigerant which has passed through the electric valve (63) in the branch pipe (62). A first injection flow passage (65) conducts a refrigerant to the compressor (20), the refrigerant having flowed through the branch pipe (62) and exited from the heat exchanger (64). A second injection flow passage (82) conducts a refrigerant gas component in the high-pressure receiver (80) to the compressor (20).
