Abstract

The paper examines a solar electric driven heat pump serving an office building located in southern Italy. Tosatisfy space heating and cooling demand a heat pump activated by electric energy available from solarphotovoltaic plant equipped with an electric storage is here considered. Dynamic simulations to evaluate thethermo-economic performance of this system, varying photovoltaic peak power (4.5-7.5 kW) and electricbattery capacity (3.2-9.6 kWh), are carried out. The proposed system achieves primary energy saving andequivalent dioxide carbon emission reduction up to about 82 % in comparison to the reference conventionalsystem based on a natural gas fired boiler and an electric chiller. The results show that the solar energy systemis more competitive when there is no battery storage and government incentives will be provided.
