The paper examines a solar electric driven heat pump serving an office building located in southern Italy. To satisfy space heating and cooling demand a heat pump activated by electric energy available from solar photovoltaic plant equipped with an electric storage is here considered. Dynamic simulations to evaluate the thermo-economic performance of this system, varying photovoltaic peak power (4.5-7.5 kW) and electric battery capacity (3.2-9.6 kWh), are carried out. The proposed system achieves primary energy saving and equivalent dioxide carbon emission reduction up to about 82 % in comparison to the reference conventional system based on a natural gas fired boiler and an electric chiller. The results show that the solar energy system is 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. To satisfy space heating and cooling demand a heat pump activated by electric energy available from solar photovoltaic plant equipped with an electric storage is here considered. Dynamic simulations to evaluate the thermo-economic performance of this system, varying photovoltaic peak power (4.5-7.5 kW) and electric battery capacity (3.2-9.6 kWh), are carried out. The proposed system achieves primary energy saving and equivalent dioxide carbon emission reduction up to about 82 % in comparison to the reference conventional system based on a natural gas fired boiler and an electric chiller. The results show that the solar energy system is 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.
