Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/003754
Kind Code:
A1
Abstract:
A refrigeration cycle device (1) is equipped with a high-order side refrigerant circuit (10), a low-order side refrigerant circuit (20), and a heat medium circuit (30). The high-order side refrigerant circuit (10) has a high-order side compressor (11), a high-order side four-way valve (12), a high-order side refrigerant heat exchanger (13), a high-order side expansion valve (14), a cascade heat exchanger (15), a first heat medium heat exchanger (16), a first switching valve (17), and a second switching valve (18), and circulates a high-order side refrigerant. The low-order side refrigerant circuit (20) has a low-order side compressor (21), a low-order side four-way valve (22), the cascade heat exchanger (15), a low-order side expansion valve (24), and a second heat medium heat exchanger (25), and circulates a low-order side refrigerant. The heat medium circuit (30) distributes a heat medium to the first heat medium heat exchanger (16) and the second heat medium heat exchanger (25).
