Eco-friendly refrigerant like hydroflurocarbons and hydrocarbons are replacing chlorofluorocarbons application.CFC is the most important member of CFC refrigerants. This paper, gives alternate to refrigerants that are causes ill effect on environment. Their performance with respect to recently used refrigerant compared. By this comparison benefits of Ecofriendly refrigerants discussed. © (2014) Trans Tech Publications, Switzerland.
