摘要

PV/T-GCHPs是实现地热能与太阳能互补利用的一种系统。设计和搭建了系统的实验平台,通过实验和模拟分析PV/T-GCHPs制热工况时埋管出水温度对光伏组件发电性能的影响,比较了PV/T-GCHPs与GCHPs制热性能系数。结果表明：当热泵负荷为75%、循环水流量为0.28 kg/s、地埋管出口水温度为8 ℃时,光伏组件最高发电效率提高6.4%,PV/T-GCHPs平均制热性能系数比GCHPs提高2.2%,最大制热性能系数提高2.4%。

Abstract

PV/T-GCHPs （photovoltaic/thermal - ground-coupled heat pump systems） is a system that realizes the complementary utilization of geothermal energy and solar energy. The experimental platform of the system was designed and built, and the effect of the temperature of the outlet water from the borehole on the power generation performance of the photovoltaic panel was analyzed through experiment and simulation under the heating conditions of the PV/T-GCHPs, and the heating performance coefficients of PV/T-GCHPs and GCHPs were compared. The results show that when the heat pump load is 75%, the circulating water flow rate is 0.28 kg/s, the outlet temperature of the buried pipe is 8 ℃, the maximum power generation efficiency of photovoltaic panels is increased by 6.4%, and the average heating performance coefficient of PV/T-GCHPs is increased by 2.2% compared with GCHPs. The maximum heating performance coefficient is increased by 2.4%.
