REFRIGERATION CYCLE DEVICE

Title:

REFRIGERATION CYCLE DEVICE

Document Type and Number:

WIPO Patent Application WO/2021/157286

Kind Code:

A1

Abstract:

This refrigeration cycle device comprises an evaporation pressure regulating part (20, 210) placed downstream of a plurality of evaporation parts (16, 18, 19) and regulating a refrigerant evaporation pressure in the plurality of evaporation parts (16, 18, 19). The plurality of evaporation parts (16, 18, 19) consist of at least three or more evaporation parts. One of the plurality of evaporation parts (16, 18, 19) is defined as a first evaporation part, and another one of the plurality of evaporation parts (16, 18, 19) is defined as a second evaporation part. An evaporation pressure regulating valve 20 is configured to be able to regulate the refrigerant evaporation pressure in the first evaporation part to either a higher value or a lower value than the refrigerant evaporation pressure in the second evaporation part.
