摘要
光伏光热(PVT)系统既可发电,又可为建筑提供生活热水,实现了热电联供。介绍了PVT系统流程及PVT模块的结构,建立了PVT系统的传热数学模型。采用Matlab对模型进行求解,进行了精度验证。对夏热冬暖地区实际PVT系统的综合热效率(包括PVT模块发电效率、蓄热水箱热效率)进行了模拟计算。
Photovoltaic/thermal （PVT） system can generate electricity and provide hot water for buildings, and the heat and power cogeneration is achieved. The technological process of PVT system and the structure of PVT＇module are introduced, and a heat transfer mathematical model for PVT system is established. The model is solved by Matlab and its accuracy is verified. The comprehensive thermal efficiency of the actual PVT system including the power generation efficiency of PVT module and the thermal efficiency of heat storage tank in the subtropieal region, is simulated.
