Abstract This work investigates the result of an experimental study carried out to determine the performance of direct expansion of LPG in dual system, which is locally available and comprises 24.4% propane, 56.4% butane and 17.2% isobutene. The availability of electricity in most part of the India is not till continuous which interrupt the refrigeration process in household refrigeration system as well as in industrial one as there is main power consuming device in vapour compression refrigeration system is a compressor. To check the feasibility of obtaining refrigerating (cooling) effect by directs expansion of LPG, with elimination of compressor; this system is build. This dual purpose LPG system in which main purpose of LPG as a fuel for cooking and simultaneously use to obtain refrigerating (cooling) effect. Such type of system is very effective in household applications as well as commercial one. Using the same concept car air conditioning can be achieved in future e scope. The system is purely based on Trial and Error Method. LPG is highly inflammable but use of strong design and standard equipments can minimize the risks associated with LPG.

1. Introduction Glancing in future of refrigeration and air-conditioning field it is necessary to build the environmental friendly safe and cost effective alternative refrigeration systems and refrigerant for conventional domestic refrigeration system. LPG the fuel of new generation, with this scheme the main aim of this paper to check whether it is possible to achieve the refrigerating effect by direct...
