Abstract
A model has been established based on numerical calculation to analyze a vertical tube in tube stainless steel generator with forced convective boiling. Refrigerant vapour is generated from the weak refrigerant-absorbent solution takes place in the middle tube of the generator, when hot water through the outer side is used as boiling medium and the pipe arrays inserted is the phase change material containment. This paper shows the results of the TRNSYS modeling and simulation of a solar absorption cooling system under the weather conditions of Chennai in order to partially satisfy the thermal demand of a building room. The maximum hourly thermal load reaches 165 kW. The suggested model operates with concentrating parabolic collectors, a NH3-H2O single effect absorption air-conditioning system, hot water storage with PCM and an external auxiliary boiler. As a result of the method simplifying for the varying climate and different orientation of the components are analyzed. These outcomes show that the prime system could succeed a yearly solar fraction of 0.58.
