摘　　要：近年来,太阳能发展广受关注,本文提出并设计一种光伏驱动式PV/T热水集热系统,结构上以吸热板拼接小型PV板,利用光伏板产生的电能驱动循环水泵带动系统自驱动运行。其全天温度分为快速上升期、近匀速上升期、高位波动期与下降期四个部分,系统全天平均电效率可维持在10%上下,且热效率达到39.9%,综合效率68%,全天水箱升温达到32°C。经计算,系统每年可以节约73.5kWh电能,相当于节约了29.4kg的标准煤消耗同时减少近20kg碳排放,节能效果显著。In recent years,the development of solar energy has attracted wide attention.This paper proposes and designs a photovoltaic driven PV/T hot water heat collection system,which is structurally spliced with small PV panels by using heat absorbing plates,and uses the electric energy generated by the photovoltaic panels to drive the circulating water pump to drive the system to run automatically.The temperature of the whole day is divided into four parts:the fast rising period,the nearly uniform rising period,the high fluctuation period and the falling period.The average electrical efficiency of the system can be maintained at about 10%,the thermal efficiency reaches 39.9%,the comprehensive efficiency reaches 68%,and the temperature of the water tank reaches 32°C throughout the day.According to calculation,the system can save 73.5kWh of electric energy every year,which is equivalent to saving 29.4kg of standard coal consumption and reducing nearly 20kg of carbon emissions,with remarkable energy-saving effect.
