一种空气流质型光伏光热综合利用系统的实验研究
An experimental research on hybrid photovoltaic & thermal utilization system with air as working fluid
摘要
Abstract
Under stable illumination conditions,consecutive 8 hours temperature and efficiency tracking tests for a self-design hybrid photovoltaic & thermal (PV/T) utilization system with air as working fluid have been carried out in three cases.After optimum selecting of air fan and water pump and elimination of heat radiation from them,the thermal efficiency and the total efficiency curves that change with water temperature in the insulation barrel are achieved.The thermal efficiency is not monotonous change,but increases after a decline,and then drops down again.Its initial change is quick.When the water temperature increases by 8.1 ℃ and thermal efficiency is about 16.90%,the thermal efficiency achieves the maximum point.Later,the temperature increases more and more slowly with time.Meanwhile,the thermal efficiency and total efficiency reduce gradually.But the electrical efficiency is basically unchanged.So the total efficiency changes similarly with the thermal one.The maximum of total efficiency is 18.81%,which is the best working point of the system.关键词
