WINDOW AIR-CONDITIONER USING LPG.

A few days ago refrigeration was regarded as luxurious branch of engineering in the whole world but it has become a part and parcel of present society. Absorption refrigeration cycle is one of the oldest known cycles used for producing refrigeration effect. Great strides had been made to use the heat energy instead of work energy for producing refrigeration as it can be available from the waste fuel and solar energy. The one disadvantage of the system is its low co-efficient of performance (C.O.P.) as compared to the vapor compression system, but it can be acceptable if we use heat energy which is going waste or solar energy; as it is available at no cost. This paper deals with the system which is designed and fabricated, using fuel of Liquefied Petroleum Gas (LPG) as a heating media to generator of vapor absorption system. It not only uses fuel of high calorific value and low cost but also to increase the C.O.P. of system on increased load of the room by regulating the flame temperature and pressure inside the generator such that the system can be affected. Capacity of system is 1.5 T.R.
