Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/066001
Kind Code:
A1
Abstract:
A refrigeration cycle device (1) comprises a compressor (10), a condenser (20) that is a first heat exchanger, a receiver (42), a first expansion device (50), an evaporator (60) that is a second heat exchanger, pipes (80-84), a bypass pipe (85), and a second expansion device (71) that is provided in the bypass pipe (85). The pipes (80-84) constitute a refrigerant circuit (110) to circulate a non-azeotropic refrigerant mixture through, in order, the compressor (10), the first heat exchanger, the receiver (42), the first expansion device (50), and the second heat exchanger. The bypass pipe (85) sends the non-azeotropic refrigerant mixture from the receiver (42) to the compressor (10) intake port without passing through the first expansion device (50) and the second heat exchanger. The end of the bypass pipe (85) inserted into the receiver (42) is provided with a refrigerant inlet (D). The refrigerant inlet (D) is configured such that the area of an opening to intake the non-azeotropic refrigerant mixture in a gas state is changed when the liquid level in the receiver (42) changes.
