Abstracts: This work investigates the result of the study we carried out to determine the performance of air conditioner when a propane-butane mixture that is liquefied petroleum gas (LPG) which is locally available and comprises 70% propane, 28% butane and 2% isobutene which vary from company to company. The LPG is cheaper and possesses an environmental friendly nature with no ozone depletion potential (ODP). It is used in world for cooking purposes. The various methods of refrigeration on the basis of standard refrigerant discussed. The performance para meters investigated is the refrigeration effect in certain time. The air condition works efficiently when LPG was used as refrigerant instead of R 22. Also from the experiment which is done in atmospheric condition, we can predict the optimum value of cooling effect with the suitable operating condition of regulating valve and capillary tube of the system. The results of the present work indicate the successful use of this propane-butane mixture as an alternative refrigerant to R22 in air conditioning system.
