Modeling of a solar absoprtion cooling system for Guayaquil, Ecuador

This paper shows the results of the TRNSYS modeling and simulation of a solar absorption cooling system under the weather conditions of Guayaquil, Ecuador in order to partially satisfy the thermal demand of an office building. The maximum hourly thermal load reaches 153 kW. The proposed model utilizes evacuated tube collectors, a LiBr-H₂O single effect absorption chiller, hot water storage and an auxiliary external boiler. As part of this study, the results of the system optimization by varying the dimensions of their main components are indicated. These results show that the optimal system could achieve a yearly solar fraction of 0.6.
