BRIEF ON USING ISOBUTANE MIXTURE FOR COOLING SYSTEM AND COMPARATIVE ENERGY ANALYSIS WITH CONVENTIONAL SYSTEM

At present energy conservation is a vastly researched and renowned topic. It is also of need. In India as a domestic fuel iso-butane gas is stored in liquefied state before its utilization. The energy spent for pressurizing is almost wasted. If this can be expanded in controlled manner it can produce cooling effect. This property has been used for refrigeration and air conditioning. So that the liquefied form of iso-butane can be used for cooling by expansion and the expanded gas can be further used for combustion. Hence actual setup for checking cooling effect of LPG is considered and modelled by many researchers. In this article theoretical comparison of this system with conventional on basis of COP is calculated; to check its liability safety and other factors are also considered. Storage after expansion is majorly faced conflict is discussed. Conclusions are drawn based on the cooling effect produce. This system can limit use of conventional refrigerants.
