摘要
文章搭建了热管式太阳能PV/T热泵系统,设计了供热和集热两种运行模式,并选取了日均太阳辐射强度和室外温度基本接近的两个工作日,对两种运行模式下,该系统的各项性能进行了实验研究。分析结果表明,供热模式下,热管式PV/T热泵系统日均热效率为33.9%,日均电效率为12.2%,比单一光伏发电系统的日均电效率提高了25.7%,日均COPth、日均COPpv/t分别为2.52,3.26;集热模式下,热管式PV/T热泵系统日均热效率为25.3%,日均电效率为12.9%,比单一光伏发电系统的日均电效率提高了14.2%,日均COPth、日均COPpv/t分别为1.82,2.33。因此,供热模式下热管式太阳能PV/T热泵系统的绝大部分性能优于集热模式。
The testing rig of heat-pipe PV/T heat pump system was constructed. Two working modes, heating mode and heat charging mode, were designed. The daily performance of two working modes was studied in two working days with equivalent daily average solar radiation and ambient temperature. The results showed that the average electrical efficiency, thermal efficiency, COPth and COPpv/t of heat-pipe PV/T heat pump system were 12.2%, 33.9% , 2.52 and 3.26 respectively under the heating mode, and the electrical efficiency of PV/T system is improved by 25.7% compared with independent PV panel; While the above performance parameters were 12.9%, 25.3%, 1.82 and 2.33 respectively under the heat charging mode, and the electrical efficiency was improved by 14.2% compared with independent PV panel. The performance of heating mode was better than that of heat charging mode.
