Prototype of PVT-driven dual-source heat pump with borehole thermal energy storage achieves coefficient of performance of 4.07

AI Summary

An international team has developed a hybrid energy system using photovoltaic-thermal collectors and borehole thermal energy storage to provide low-carbon heating for livestock. The full-scale prototype has shown high efficiency and reduced reliance on fossil fuels during tests in Italy.

An international research team has developed and tested a hybrid energy system combining photovoltaic-thermal collectors, borehole thermal energy storage, and a dual-source heat pump to supply low-carbon heating for livestock buildings. The full-scale prototype, demonstrated on an Italian swine farm, showed high efficiency, strong seasonal performance, and reduced reliance on fossil fuels while enabling partial self-supply of electricity and heat.
