Abstract

This research describes the study of ventilation system for the closed housing model using solar energy. The system consists of an electric generation system using solar energy, a ventilation system and a model of closed housing. The ventilation system installed to the housing consists of cooling pads, a 36 watt water pump and a 164 watt ventilating fan. The DC voltage of 12 Volt from the total power of 330 watt solar cells is used as the primary electrical energy in this experiment. The experimental results show that evaporation at cooling pads can decrease the temperature inside the housing with satisfied level of air

2

temperature of closed-housing is of 4.68qC and the average difference value is of 2.03qC. The average relative humidity inside the closed housing is in the range of 89.06 – 92.85%

Keywords: Evaporative cooling system, Closed housing, Ventilation, Solar Energy.
