PV-SAHP/HP复合系统不同运行模式下系统性能的实验研究

为拓展太阳能的利用方式,减少能源消耗,将光伏-太阳能热泵与热管进行有机结合,提出了光伏-太阳能热泵/热管复合系统的思想;设计并搭建了光伏-太阳能热泵/热管复合系统实验测试平台,对热管单独运行和热泵单独运行模式下系统的性能进行了实验研究.结果表明,在热管单独运行模式下,系统的日平均光热效率低于普通的PV/T系统;而热泵单独运行模式下,系统具有较高的日平均光热效率及热泵的性能系数.;In order to widen the solar energy utilization ways and reduce the energy consumption, a photovoltaic solar-assisted heat pump/heat pipe(PV-SAHP/HP) compound system is proposed.An experiment platform is designed and constructed to study the system's performance under heat pump and heat pipe operation mode.The results show that under the heat pipe operation mode, the system's daily average photothermal efficiency is lower than the common solar water heating system.However, a higher daily average photothermal efficiency and COP are presented under heat pump operation mode
