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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
