Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/048897
Kind Code:
A1
Abstract:
A refrigeration cycle device (100), wherein a non-azeotropic mixed refrigerant circulates. The refrigeration cycle device (100) comprises a compressor (1), a first heat exchanger (2), an expansion valve (3), a second heat exchanger (4), and a blower (6). The second heat exchanger (4) has a first port (P1) and a second port (P2). The blower (6) forms an airflow (Wd1) that passes through the second port (P2) and the first port (P1) in that order. The non-azeotropic mixed refrigerant circulates through the compressor (1), the first heat exchanger (2), the expansion valve (3), the first port (P1), and the second port (P2) in that order. At the pressure of the non-azeotropic mixed refrigerant in the second heat exchanger (4), 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.
