C.O.P DERIVATION AND THERMODYNAMIC CALCULATION OF AMMONIA-WATER VAPOR ABSORPTION REFRIGERATION SYSTEM

In the current trends globally, the excessive utilization of the energy and overconsumption of fuel has resulted in the global warming and environmental pollution. The Absorption cooling offers the possibility of using heat to provide cooling. F or cooling purpose the required heat input is obtained from the excessive heat of the boiler or from non conventional power sources like solar energy. NH3-H2O system ammonia used as a refrigerant and water is used as an absorbent, these two liquids served as standard and a refrigerant cycle is produced. The system VARS in environment friendly and does not deplete the atmosphere. Thus it is essential to create awareness in the world for this system for it is an alternative system which i s more environmental friendly. The objective of this paper is to present empirical relations for evaluating of the performance of a single stage vapor absorption system.
