Vapour compression refrigeration has been used in almost everywhere in the world. In that VCRS, refrigerant has ozone layer depleting potential and green house gases. The classical refrigerants such as chloroflurocarbons, hydrochloroflurocarbons and hydroflurocarbons have created the environmental problem. So to avoid the environmental issue has to move alternate refrigerant. In this research, the alternate refrigerant has taken R410a and LPG. The experimental has been conducted by using R410a and blendes of LPG and R410a (60%&40% by weight %) with various condensing temperature like 32oC,35oC and 40oC versus various evaporating temperature. It is found that refrigerating capacity and COP increases with increases in evaporating temperatures and decreases with the increase in condensing temperatures.
