Results of an experimental study of a solar cooling system in Jaén using single effect lithium bromide absorption chiller

Abstract

The potential of absorption machines to cool, in particular, in house air-conditioning systems is well-known. Using solar thermal energy helps decreasing air-conditioning systems CO 2 emissions. The purpose of this work is to prove the effectiveness of this kind of systems to cool an average house during summertime. The setting uses an unit heater for heat dissipation. The cooling coil decreases the COP setting because the dissipation depends on external temperature. Using another renewable source of energy, like geothermal energy (Ground Source Heat Pump, GSHP), would improve the performance of the setting because, from a certain depth, ground temperature is practically constant and it is lower. The goal of this article is to present the design of the system as well as some first results for several representative days in August 2009.
