Abstract

The aim of this work is to study the integration of solar air conditioning solutions in Algerian buildings and to assess the economic and environmental benefits, for that reason, two solar air conditioning systems were investigated, the first one is a solar driven absorption cooling system, the second is a solar desiccant cooling system, the study was carried out under three different climates ; the hot and humid climate of Algiers, the hot and moderated climate of Constantine, and the hot and dry climate of Bechar. TRNSYS software was used for the simulation. Energy consumption and cost in addition to performance indicators and impact on environment were investigated and compared with a conventional vapor compression machine. The results revealed that solar air conditioning systems are perfectly adaptable to the Algerian climate with an important annual economy, and that solar desiccant cooling systems are more efficient under dry climates than humid climates.
