冷凍サイクル装置
Document Type and Number:
Japanese Patent JP7146117
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide a refrigeration cycle device that can achieve both higher cooling capacity and higher heating capacity. 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 six-way valve (12), a high-order side refrigerant heat exchanger (13), a high-order side expansion valve (14), a cascade heat exchanger (15), and a first heat medium heat exchanger (16), and circulates a high-order side refrigerant. The low-order side refrigerant circuit (20) has a low-order side compressor (21), a 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).
