Liquified petroleum gas (LPG) is one of the most important and potentially refrigerants for half-cycle air conditioning systems. Half cycle air conditioning system eliminates the compressor and condenser in providing air conditioning because working fluid in such cycles is already liquified at high pressure before passing through the system. When high pressure LPG is passed through an expansion device or a capillary tube of small internal diameter to the evaporator,  refrigerant pressure drops down suddenly as a result LPG vaporizes in the evaporator and provides cooling. In this project, we have analyzed of half-cycle window air conditioning system using LPG. Liquefied petroleum gas (LPG) is an easily available gas stored in the cylinder for household purposes which consists of 24.4% propane, 56.4% butane, and 17.2% isobutene,  which is varied from company to company and is used as a Refrigerant. The LPG is cheaper and possesses an environmentally friendly nature with no Ozone Depletion Potential (ODP) and no Global Warming Potential (GDP). The application of Air-Conditioner increased day to day as home appliances and in the industry over the last decade. We obtained the COP for the solar-powered and half-cycle air conditioning system as 6.3. Therefore, the half-cycle window air conditioning system using LPG and solar energy has enough potential field for air conditioning, but very few works have been done so far on its application in restaurants and residential properties facility and that makes the scope of the present research.
