Experimental study of thermal performances of the sloar photovoltaic-thermal hybrid system
摘要
Abstract
Heat pipe can be applied on the solar photovoltaic-thermal (PV-T)hybrid system to decrease the working temperature of solar cell of which,the photoelectric efficiency of which is increased,and the some of the heat energy is recycled at the same time so that the total energy utilization efficiency of the system is improved greatly.A thermal theoretical model of the PV-T system was established,and the solar-thermal hybrid experimental device with heat pipe is developed.Some related experiments are conducted including the tests of PV efficiency and heat transfer efficiency and exergy efficiency.The results show that the photoelectric efficiency is about 4.7%,the comprehensive efficiency of the system is about 49%,and the maximum exergy efficiency is about 8%.The overall efficiency of this system is higher than that of a pure PV system.Through comparative performance evaluation of several kinds of PV-T system, the heat pipe type PV-T system shows a significant energy-saving potential.Some energy-saving suggestions were also put forward.关键词
