Title:
REFRIGERATION CYCLE WORKING MEDIUM AND REFRIGERATION CYCLE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/029485
Kind Code:
A1
Abstract:
This refrigeration cycle working medium contains, as a refrigerant component, a fluoroolefin that undergoes a disproportionation reaction and, as a disproportionation suppressant that suppresses the disproportionation reaction of the fluoroolefin, a C1-3 fluoroalkane having a boiling point of 0°C or less (however, excluding difluoromethane). Difluoromethane (R32) may also be contained as a refrigerant component, and a C1 or C2 haloalkane, excluding the instance in which all halogen atoms are fluorine, may also be contained as a disproportionation suppressant. In this way, the combustibility can be suppressed well in a refrigeration cycle working medium that contains a fluoroolefin as a refrigerant component and contains a disproportionation suppressant.
