“…These systems can guarantee interesting primary energy saving up to 67 %, as stated by Ref. [12] even if investment costs are too high to make the technology suitable for the actual market [13]. A different way to exploit solar energy is the introduction of a photovoltaic system interacting with a reversible heat pump.…”

The paper investigates the introduction of a solar electric driven heat pump for an office building, placed in southern Italy, with low energy demand in comparison with the most common type of Italian buildings. Dynamic simulations to evaluate energy, environmental and economic performance of the proposed system, varying photovoltaic peak powers (4500 W -7500 W), tilt angles (20° -50°), electricity and natural gas unit prices, are carried out. To meet heating and cooling demand a heat pump driven by electricity available from solar photovoltaic panels is here considered. The system based on solar electric driven heat pump shows a saving in terms of primary energy and equivalent CO2 emission reduction up to about 81 % if compared to the reference conventional system based on a boiler fueled by natural gas and an electric-driven chiller. The results highlight that the solar based energy conversion system is more interesting when the electric energy and natural gas unit prices are high and government incentives are available.

“…[12] systems based on solar thermal collectors can achieve interesting primary energy saving up to 67 %, even if investment costs need to be lower to make the technology suitable for the market [13]. Solar source could be also exploited for heating and cooling purpose introducing a reversible EHP interacting with a PV system.…”

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.

“…Among them strong efforts were focused on thermally-activated refrigeration devices [3] such as adsorption [4] and absorption heat pumps [5], evaporative and ejector cooling systems [6], HVAC (heating and ventilation air conditioning) desiccant-based air handling unit [7]. These systems, compared with fossil fuel-based energy conversion systems, can reach a primary energy saving up to 67% [8], even if investment costs are too high to make these technologies interesting for the actual market [9]. A different way to use solar energy for heating and cooling purpose is the introduction of a photovoltaic system interacting with an electric heat pump (EHP).…”

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 is here considered. In order to improve the self-consumption of electricity available from photovoltaic system different configurations were considered introducing an electric storage and an electric vehicle. 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 about 96% in comparison to the reference conventional system based on a natural gas fired boiler, an electric chiller and the national electric grid. The results show that fossil fuel primary energy saving is higher when there are no storage battery and electric vehicle.
