Experimental analysis of an air conditioner powered by photovoltaic energy and supported by the grid

The equipment has been monitored during the 12 h of daily usage (from 8 to 20 h), to condition an office with 35 m2 in Alicante (Spain). The results during a cooling period of 6 months have demonstrated that the average EER could be close to 15. Both the solar contribution and the production factor are close to 65%. Experimental correlations are given in order to extend the obtained results to simulate other climatic conditions and demands.
