Performance analysis of flat tube evaporator in hybrid photovoltaic-thermal solar heat pump air-conditioning system

根据太阳能光伏光热蒸发器与制冷系统之间的能量平衡,建立了光伏光热扁管式蒸发器性能的数理模型。该模型考虑了光伏光热扁管式蒸发器的传热系数变化,并分析了太阳辐射强度、环境温度、制冷循环的蒸发温度对光伏光热扁管式蒸发器的电池板温度、电池板光电转换效率、电池板发电功率以及光伏光热蒸发器散热量的影响。

According to energy balance between photovohaic - thermal evaporator and refrigeration system, the physical and mathematic model of fiat tube evaporator in hybrid photovohaic - thermal solar heat pump air - conditioning system was established. It was taken into account for heat transfer coefficient change in fiat tube evaporator. It was analyzed that incident solar intensity, ambient temperature, evaporation temperature in refrigeration cycle had influence on solar eell temperature, electrical efficiency, electrical power and heat transfer rate.
