EXPERIMENTAL STUDY OF A MOBILE SOLAR AIR COOLERWITH A CLAY-BASED COOL WATER RESERVOIR

This paper focuses on the simulation in SolidWorks and experimental study of a mobile solar air cooler using clay as the base material. This device is an energy-autonomous and economically viable response to the challenges of climate change and limited access to conventional air conditioning in developing countries. The methodology used incorporates specifications and the optimal choice of components necessary for the prototype (clay, a 1 W DC fan, four 500 Wp photovoltaic panels with a 2 kVA / 1.6 kW 48 ,V converter and a 48 V 200 Ah battery bank)as well as the experimental characterisation of the prototype. The results show a temperature reduction of 5 C (indoor temperature of 25C for 30 C outdoors) with relative humidity of 55%, autonomy of one day and daily consumption of 7 kWh. The cost of producing the device is 221,500 CFA francs.
