PV-Trombe墙性能影响因素模拟研究
Simulation Study on Influencing Factors of PV-Trombe Wall Performance
摘要
Abstract
The simulation method was used to analyze the effects of solar irradiance and photovoltaic cell cov-erage rate on the performance of PV-Trombe wall.When the coverage rate of photovoltaic cells is con-stant,the increase of solar irradiance is conducive to improving the heat gain of the room and the power gen-eration of photovoltaic cells,and the thermal efficiency of PV-Trombe wall also increases accordingly,how-ever,the electrical efficiency of PV-Trombe wall de-creases due to the increase of photovoltaic cell tempera-ture.Under certain condition of solar irradiance,the in-creasing of photovoltaic cell coverage rate reduces the amount of sunlight incident on the heat absorbing plate,resulting in the decrease of room heat gain and PV-Trombe wall thermal efficiency,but it is conducive to increasing the power generation of photovoltaic cells.The electrical efficiency of PV-Trombe wall,which takes the temperature of photovoltaic cells as the main influencing factor,basically remains unchanged when the solar irradiance is constant.In practical applica-tion,the optimal parameter configuration of PV-Trombe wall should be determined in combination with the electrical load and thermal load of the project.关键词
