Comprehensive Performance Research On Building-integrated Power-heating-cooling Cogeneration Photovoltaic Module

With the increasing of building energy consumption,more and more attention is paid to the use of renewable energy to reduce the energy consumption of buildings.Solar energy is a clean and renewable energy,space noctuqnal cooling has great development potential.In this thesis,power-heating-cooling cogeneration photovoltaic module was reseached,which combined photovoltaic/thermal technology and space noctuqnal cooling technology.The quality and power-heating-cooling performance of this module was studied and analyzed systematically.The reseach provides a solution and method for this module from technology to product conversion and engineering application.In this thesis,the structure,working procedure,working principle and performance parameters of the module were summarized,four ways of integration mode were sorted out and the corresponding installation diagram and effect diagram was drawn.As a new components of building,the analysis of its comprehensive performance is the premise of technological transformation and engineering application.This thesis presents the order,method and content of quality performance testing,and thermal performance was tested.Its power-heating-cooling performance in the outdoor steady state operation and continuous operation was studied by experiment.By testing and experimental results,thermal efficiency is 44.9%,the total heat loss coefficient is15.35W/(m~2·~oC),the highest photoelectric conversion efficiency is 14.1%,and the total cooling capacity is 40~60W/m~2 in the clear night.According to the test and experimental data,the office building in Tianjin area as an example,it is concluded that the application of this module can meet the demand of power,heating and cooling.Through the analysis and research of structure,working procedure,working principle,performance parameters,quality performance and power-heating-cooling performance of power-heating-cooling cogeneration photovoltaic module structure,it lays the foundation for technological transformation and engineering application of this module,and provides a new solution for reducing building energy consumption.
