Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/070314
Kind Code:
A1
Abstract:
A refrigeration cycle device (100), wherein an air blower (5) forms an air flow (Wd1) that passes from a second port (P2) to a first port (P1) in that order and from a fourth port (P4) to a third port (P3) in that order. A non-azeotropic mixed refrigerant circulates through a compressor (1), the first port (P1), the second port (P2), a refrigerant container (11), an expansion valve (3), and a second heat exchanger (4) in that order, as well as through the compressor (1), the third port (P3), the fourth port (P4), the refrigerant container (11), the expansion valve (3), and the second heat exchanger (4) in that order. At the pressure of the non-azeotropic mixed refrigerant in a first heat exchanger (2), the temperature gradient of the non-azeotropic mixed refrigerant, which is the relationship between the dryness of the non-azeotropic mixed refrigerant and the temperature of the non-azeotropic mixed refrigerant, is expressed as an upwardly convex monotonic increasing curve in a coordinate plane with a horizontal axis representing the dryness and a vertical axis representing the temperature.
