Substitution Of Non-Eco friendly Refrigerants By Hydrocarbon Refrigerants: A Review
Due to the growing concern regarding the significant impact of CFCs, HCFCs and HFCs on global warming and
ozone depletion the refrigeration and air-conditioning sector has strong need for the experimental data on the use of eco
friendly refrigerants. Several environmental regulations have already imposed restrictions on the use of halogenated
refrigerants. The paper contains a review on substitution of non-eco friendly refrigerants with HCs from refrigerating
systems. HCs have excellent characteristics from environmental as well as thermodynamics point of view. This study
contains well organized information on the experimental studies on application of pure and mixtures of HC refrigerants as
substitutes in refrigeration systems. Based on the theoretical analysis it is concluded which HC refrigerants are most likely to
be used as future options.
