Energy, exergy, economic and environmental assessment of the triangular solar collector assisted heat pump

The solar air collector assisted source heat pump is demonstrated to be an efficient clean heating technology, while the research on its working modes, and corresponding energy, exergy, economic, environmental (4E) analysis insufficient. In this study, a novel triangular (TSAHP) for building proposed, three modes including preheating, series parallel are illustrated. energy model established used determine optimal mode, solved by Python environment. Four scenarios TSAHP with areas of (TSAC) conventional (ASHP) compared based mode. Thermodynamic performance four under different conditions analyzed, result indicate that 3 m2 TSAC can reduce power consumption exergy destruction ASHP components 321.9 kWh 784.6 MJ respectively during whole period. Economic evaluation shows has shortest payback period moderate area, economic advantages at low nominal interest rate high electric cost large area. addition, life cycle, 1 CO2 emission more than 4500 kg.
