摘要
为了提高PV/T装置的太阳能利用效率,文章提出了一种基于微热管阵列的太阳能PV/T热泵系统,并在恒温供热条件下分析了该系统中PV/T收集器的热、电性能和热泵COP的全天变化趋势,最后将PV/T收集器的电性能与单一光伏发电系统进行对比分析。分析结果表明:在测试时间段内,PV/T收集器的平均热效率为38.7%;PV/T收集器的平均电效率为12%,比单一光伏发电系统提升了27.7%;PV/T收集器的光热光电综合平均效率为70.3%;热泵的平均COP为2.7。
In order to improve the efficiency of solar PV/T equipment,a solar PV/T heat pump system based on micro heat pipe array is proposed in this paper.Under the condition of constant temperature heating,the thermoelectric performance of the PV/T collector and the COP of the heat pump are both analyzed over a day.Finally,the electrical performance of the PV/T collector is compared with a single photovoltaic system.During the test period,the experimental anyalysis results show that the average thermal efficiency of the PV/T collector is 38.7%,the average electrical efficiency of the PV/T collector is 12%,which is 27.7%higher than that of a single pv system,the average overall energy efficiency of the PV/T collector is 70.3%,the average COP of the heat pump is 2.7.
