Résumé

The use of heat produced by solar thermal collectors is an interesting option for thermal driven air conditioning process. Three technologies are commercially available: absorption, adsorption and desiccant cooling systems. This paper is focused on solar desiccant cooling and solar absorption systems. This study is part of a work on modelling and optimization of solar desiccant systems conducted in the context of a PhD thesis in collaboration between EDF R&D and CETHIL. The aim of the study is to assess energetic and comfort performances of these solar cooling systems integrated in an office building. Solar systems are positioned in reference to standard air-conditioning equipments (compression and variable refrigerant equipments). For that purpose, the link between solar air-conditioning system and building is predominant. Therefore, the modelling takes place in a dynamic thermal building simulation software, CA-SIS developed by EDF R&D to obtain overall results. The article presents main results of assessments regarding the energetic and economic balances and the thermal comfort of the occupants.
