Impianto sperimentale geotermico a bassa entalpia per il riscaldamento serricolo: Valutazioni ambientali
The use of fossil fuels for greenhouse heating may cause negative impacts on the environmental state and air quality. In this context, geothermal heat pumps can meet the energy needs of the greenhouses with low environmental impact. In this study we have analyzed and compared the technical, energetic, environmental and agricultural performance of a pilot plant “photovoltaic - geothermal heat pump” and a conventional hot air generator fueled by LPG for heating of two experimental greenhouses. The experimental tests performed and the life cycle analysis (LCA) of the thermal energy produced by the two heating systems have made it possible to demonstrate that geothermal heat pumps are an alternative to conventional thermal plant because they provide suitable microclimatic conditions for crop growth in greenhouse with low environmental impact.
