The paper examines a solar electric driven heat pump serving an office building located in southernItaly. To satisfy space heating and cooling demand a heat pump activated by electric energy available from solarphotovoltaic plant is here considered. In order to improve the self-consumption of electricity available fromphotovoltaic system different configurations were considered introducing an electric storage and an electricvehicle. Dynamic simulations to evaluate energy performance of the system varying photovoltaic peak power(4.5–7.5 kW) have been carried out. The proposed system achieves a fossil fuel primary energy saving up to about96% in comparison to the reference conventional system based on a natural gas fired boiler, an electric chiller andthe national electric grid. The results show that fossil fuel primary energy saving is higher when there are nostorage battery and electric vehicle.

Abstract
The paper examines a solar electric driven heat pump serving an office building located in southernItaly. To satisfy space heating and cooling demand a heat pump activated by electric energy available from solarphotovoltaic plant is here considered. In order to improve the self-consumption of electricity available fromphotovoltaic system different configurations were considered introducing an electric storage and an electricvehicle. Dynamic simulations to evaluate energy performance of the system varying photovoltaic peak power(4.5–7.5 kW) have been carried out. The proposed system achieves a fossil fuel primary energy saving up to about96% in comparison to the reference conventional system based on a natural gas fired boiler, an electric chiller andthe national electric grid. The results show that fossil fuel primary energy saving is higher when there are nostorage battery and electric vehicle.File | Dimensione | Formato | |
