Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/210398
Kind Code:
A1
Abstract:
Provided is a refrigeration cycle device that uses an absorbent to change the composition ratio of a refrigerant used in a refrigeration cycle, wherein an increase in the time required to change the composition ratio is suppressed. This refrigeration cycle device (100) is provided with a refrigeration cycle (50), an adsorption unit (70), and a first bypass flow passage (80). The refrigeration cycle includes a compressor (10), a radiator, an expansion mechanism (30), and an evaporator, and uses a non-azeotropic refrigerant mixture that includes a first refrigerant and a second refrigerant. The adsorption unit includes an adsorbent (72a), and stores the first refrigerant adsorbed by the adsorbent. The adsorbent adsorbs the first refrigerant, and does not absorb the second refrigerator or has a lower adsorption performance for the second refrigerant than that for the first refrigerant. The first bypass flow passage connects a first end, which is the high-pressure part of the refrigeration cycle, and a second end, which is the low-pressure part of the refrigeration cycle. The absorption unit and a valve (82) are arranged in the first bypass flow passage.
