摘要
搭建了热管式PV/T(photovoltaic/thermal)热水系统的实验装置,测试了太阳辐射强度、室外空气温度、联箱入口水温和循环水量等因素对系统性能的影响.结果表明:由于光伏电池覆盖率高和PV板背板材料导热性能低,系统热效率低于30%;随着太阳辐射强度和室外空气温度的增加,系统的热效率线性上升,电效率线性下降;联箱入口水温和循环水量对系统的热性能影响明显,对电性能影响不大.
The testing rig of heat pipe PV/T hot water system was established to test the effect of solar radiation,ambient temperature,water box inlet temperature and circulating water flow rate on energy performance. The testing results show that the thermal efficiency is less than 30% due to high PV cell coverage ratio and low thermal conductivity of base panel. With the increase of solar radiation and ambient temperature,the thermal efficiency increases linearly and the electrical efficiency decreases linearly. And the water box inlet temperature and circulating water flow rate have obvious influence on the thermal performance but less influence on the electrical performance.
