Solar photovoltaic/thermal integration (PV/T) and heat pump are very important techniques for energy conservation and carbon reduction. A practical design for an integrated PV/T and heat pump system is presented, the integrated system is called the Photovoltaic-Indirect Expansion Solar Assisted Heat Pump (PV-IESAHP) system, which uses the heat energy supplied by PV/T as an evaporating heat source and can achieve high coefficient of performance(COP). It is essential to master the completed design idea and thermodynamic analysis method for the integration of PV/T and heat pump. In this study a kind of theoretical and matching performance model of the PV-IESAHP system is established, and a series of experiments were conducted to study the performance of the heat-pipe type PV/T experimental system and heat hump experimental system. Moreover, energy and energy analyses were used to investigate the performance of the systems. The results show that the COP of the PV-IESAHP system is about 4.0, and the energy eff... |
