Analyses on Electric Peak Load Reduction by Solar Electric Powered Room Air Cooling for Apartment Housings in the Mena-Region

In this paper, possibilities of electric peak load reductions in the MENA-Region, using a photovoltaic powered air conditioning system for residential buildings, are considered. For this purpose, a smallscale photovoltaic plant is simulated and compared with the electric power demand of a simulated air conditioning unit. While the demand of the A/C unit is more than three times higher than the yield, the mismatch is used to introduce a possible smaller A/C unit. There, the thermal performance is observed under maximum usage of the solar energy yield. In this scenario, the thermal comfort is analysed and compared with real temperature measurements inside the room. The final performance of the system is estimated to have a solar coverage rate of 30%, which helps to prevent rolling power cuts due to high peak loads.
