Document Type and Number:
WIPO Patent Application WO/2017/115636
Kind Code:
A1
Abstract:
The refrigeration cycle device performs a refrigeration cycle by compressing, with use of a compressor, a working medium that contains a hydrofluoroolefin (HFO) having a double bond in the molecular structure thereof. The compressor has a compression mechanism for compressing the working medium in a compression chamber, a high-pressure space for storing the compressed working medium discharged from the compression chamber, and a discharge valve that is disposed between the compression chamber and the high-pressure space and enables the working medium to be intermittently discharged from the compression chamber into the high-pressure space. The discharge valve is provided with a temperature increase suppression means for suppressing an increase in the temperature of the discharge valve.
