Less flammable hydrocarbon refrigerant as cfc-12 substitute

摘要

The recent invention is a product that can be used as a refrigerant, as well as blowing agent, for CFC-12 and HFC-134a refrigerants replacement. The product is environmental friendly, less flammable, non-toxic, and non-corrosive. The refrigerant consists of 0 to 80 % mass fraction of hydrocarbons and 20 to 70 % mass fraction of non-flammable additive (low flammability suppressant substance). The application of the refrigerant in the refrigeration system improves the system performance, and needs less refrigerant charge.
