In this study, a new type of distributed food waste-energy system coupled with PV/T heat pump was developed. Both mathematical modeling and thermodynamic analysis were carried out for the new system, based on which the performance evaluation index of the new system was proposed. According to the research results the solar PV/T heat pump system can perform consistently in providing the thermal energy and electric energy required for the distributed food waste-energy system, thus significantly improving the efficiency of the new system, with the improvement efficiency varying from 10% to 15% at the same ambient temperature. This is expected to make the application of the distributed food waste-energy system possible in low- temperature environments.
