摘要
以太阳能为主的新能源利用技术近年来得到迅速发展。介绍了一种采用环形热管降低光伏电池片温度的新型复合式太阳能热电系统,提高了太阳能系统的综合利用率。分析了系统的基本原理和主要构成,同时搭建室内太阳能光热光电实验平台,进行太阳能热电系统稳态特性的测试研究,对太阳辐射强度、空气温度、空气流速及热泵蒸发温度等影响因素进行分析和探讨。该系统对太阳能在建筑中的综合利用有实际应用价值。
New energy utilization like sober has been developed quickly during these years. In this paper, a new combined solar photovoltaie/thermal (PV/T) system was introduced. Gravitational loop heat pipe was applied in this solar system to increase the overall solar utilization efficiency. The principle of the PV/T system was introduced. The new combined solar system was built, tested and analyzed in the tab. The steady-state charac-teristics of the new system were studied such as the effects of solar radiation intensity, air temperature, air ve- locity and evaporate temperature of heat pump. This new system will be of practical use for the solar energy design and performance evaluation in the architecture.
