Résumé

A field-test of solar assisted desiccant evaporative cooling process has been carried out, which is a quite attractive cooling/dehumidification process considering various environmental problems caused by conventional electricity driven air conditioners. The process performance has been examined by means of temperature drop between outside air and supply air and COP(s) (COP value based on solar irradiation). This cooling performance was strongly influenced by solar irradiation and ambient air condition. Stable irradiation produced a higher regeneration temperature resulting higher dehumidifying performance. Influence of ambient humidity on the cooling performance was rather serious. At higher condition, the amount of dehumidified water became larger due to increase of effective adsorption capacity of the desiccant rotor. However, the temperature drop was decreased to 6.9°C. This behaviour was mainly due to simultaneous increase of humidity and temperature in the dehumidified air. In this situation, an effective evaporation in the following water spray evaporative cooler did not occur.
