Abstract

The development in the field of air conditioning experienced strong growth because of the improvement of standards living and the increased demand for comfort. However, the cold production systems are now mainly based on vapour compression refrigeration processes large consumers of electricity. Furthermore the cold production requires the use of refrigerants harmful for environment. In this context, new cold production processes must be developed and the use of neutral refrigerants is required. Moreover, the use of solar energy is an attractive concept, since the cooling requirements coincides mostly with the availability of solar radiation. The ‘desiccant cooling’ system is proposed as an alternative to traditional air conditioners. Evaporative cooling facilities potentiated by desiccation produce directly cool air, unlike the mechanical compression refrigeration units and absorption or adsorption which cools an intermediate fluid. The objective of this work is to assess the interest of the desiccant cooling technology according to weather conditions, modelling of the desiccant installation is followed by a simulation to reach the parametric study of the system on the Site of Tipaza led us to results that show the feasibility of the system.
