Performance optimization of flat heat pipe type PV/T system based on TRNSYS
Based on the analysis of the current status of solar energy technology,this paper combined solar photovoltaic(PV)modules and flat heat pipes with high efficiency,and proposed a new flat heat pipe PV/T system.In order to maximize the comprehensive efficiency of this system,combined with TRNSYS simulation,tests were carried out and optimization analysis was performed.The results showed that the hot water temperature in summer increased by 12.1%from the original 51.1℃to 57.3℃after installing the flat heat pipe,and the hot water temperature in winter increased by 15.9%from 47.6℃to 55.2℃.The overall efficiency of the summer system increased by 4.7%and the winter system by 4.8%.It can be concluded that the optimization of the performance of the PV/T air conditioning system by the flat heat pipe is obvious and provides a basis for the application of this technology in the building sector.
