REFRIGERANT MIXTURE OF R32 AND R134A FOR DROP IN REPLACEMENT OF R22

摘要

PURPOSE: A refrigerant mixture is provided to replace existing refrigerant without the reformation of existing compressor and to maintain performance coefficient and volume capacity similar to existing refrigerants. CONSTITUTION: A refrigerant mixture is a binary mixed-refrigerant consisting of 20-60 weight% of difluoromethane(R32) and 40-80 weight% of 1,1,1,2-tetrafluoroethane(R134a). The refrigerant mixture has ozone depletion potential(ODP) of 0.0 and a smaller value of global warming potential than conventional refrigerants.
