Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/020461
Kind Code:
A1
Abstract:
Provided is a refrigeration cycle device such that, even if a refrigerant containing CF3I is used, it is possible to suppress corrosion of components of the refrigerant circuit caused by the refrigerant containing CF3I. A refrigerant cycle device (1) has a refrigerant circuit (10) which is constituted by a compressor (11), an expansion valve (9), an outdoor heat exchanger (13), and an indoor heat exchanger (18) being connected to each other and circulates a refrigerant containing CF3I. The refrigerant circuit (10) has components (5, 6, 26, 30, 31, 35, 41, 57, 81, 82, 83, 93b) that come into contact with the refrigerant. At least the surface of each of the components which comes into contact with the refrigerant is formed from a corrosion-resistant material containing at least one material selected from the group consisting of metal having a zinc content of 10 wt% or less, resin other than nylon 66, and carbon.
