Feasibility analysis about application of hydrocarbon refrigerants

Presents the application of hydrocarbon refrigerants at home and abroad. Analyses the risk of them and discusses the influencing factors about the explosion limit. Validates the explosion limit and observes the explosion limit of flammable hydrocarbon mixtures with fire retardant components by experiment. Prospects the application of hydrocarbon refrigerants to automobile airconditioners and considers that they may be a dropin substitute for R12.
