A Prototype of Heat Operated Air Conditioning System

Most of air-conditioning systems used vapor compression system which used a compressor that cause to more load consumption. The researchers came up with the study of heat operated air-conditioning system or the vapour absorption process. Vapour absorption system uses the waste heat as a source of the operation instead of compressor. By using this wasted heat, it can help to reduce the load consumption in a system. The researcher used a refrigerant of ammonia and the water as the absorbent. In the design area of all the major components of the system were calculated on the basis of enthalpy parameters at different points in the system. The data were analysed using the first and second laws of thermodynamics to determine the refrigerating effect, the net heat required to run the system and the coefficient of performance (COP). Upon testing and evaluation of the prototype, the researchers concluded that it is possible to operate an air – conditioning system using a waste heat as a source of operation. The researcher also recommended to focus on getting a higher coefficient of performance of the system and to enhance the skill in brazing and welding for better appearance of the prototype.
