THE DESIGN OF AN EVAPORATOR ABSORBER AND THERMODYNAMIC ANALYSIS OF A VAPOR ABSORPTION CHILLER DRIVEN BY SOLAR-ENERGY/

An experimental absorption cooling system is being developed, driven b y the heat generated by the solar energy collection system installed a t Coventry University. The proposed absorption cooling system comprise s an evaporator/absorber cell and a generator/condenser cell. These co mponents are housed in evacuated glass cylinders to allow the processe s involved to be observed. The refrigerant-absorbent pair used is wate r and Lithium Bromide since a low temperature heat source can be used to drive the refrigerant from the carrier fluid. A thermodynamic analy sis of the absorption cooling cycle has been performed to study the ef fect of various operating conditions on the thermal performance. This paper presents the design of the evaporator/absorber cell and the resu lts of the thermodynamic analysis.
