| 摘要 |
The present invention provides a energy-saving, environmental multicomponent refrigerant, which comprises 5 to 60wt% difluoromethane (R32), 3 to 7-wt% pentafluoroethane (R125), 1 to 70wt% 1,1,1,2-tetrafluoroethane (R134a) and/or 1,1,2,2-tetrafluoroethane (R134), and 1 to 10wt% propylene (R1270). This refrigerant does not destroy stratosphere ozone layer, has low greenhouse effect latent energy, significantly improves energy-saving effect. It can save 30 to 45% energy for use in heat pump and air conditioning, and 25 to 45% for use in refrigeration respectively. Its advantage is good stability, compatibility, adaptability and practicality. The present refrigerant can be use as heat transfer medium, spray propellant, foaming agent, electric insulation medium, power circulating working medium, detergent, solvent and the like. |
