基于PVT系统存在太阳能间歇性，无法保证光热转换连续进行的特点，以及存在集热后太阳能电池背板温度过高，导致电池板光伏发电效率下降的缺陷。采用地源热泵与PVT系统相结合，解决了单纯PVT系统在日照不充足情况下热量不能连续稳定供应的问题，提高了系统的热能利用率。同时系统采用定温加热、温差循环技术，有效降低了太阳能电池背板的温度，提高了太阳能电池的光伏发电效率和地源热泵的工作效率以及系统在不同工况下连续运行的可靠性和稳定性。

Since the photo thermal conversion of PVT system can’t ensure going continuously due to the intermittency of PVT system,and the photovoltaic conversion efficiency declines due to the excess temperature of the battery backboard after heat collection,the combination of ground source heat pump and PVT system was adopted to solve the problem that the pure PVT system can't supply heat continuously. The method raised the utilization of the thermal energy. In the system,the constant temperature heating technology and temperature difference cycle technology were used to reduce the temperature of the solar bat-tery backboard effectively,improve the photovoltaic generating efficiency and ground source heat pump working efficiency,en-hance the reliability and stability of system under different working conditions,and also promote the application of PVT system.
