摘　　要：对PV／T电、热联产系统的输出性能作了简化分析,对不带玻璃盖板和带玻璃盖板的PV／T系统在一般风速(2m／s)和较大风速(5m／s)两种情况下的输出性能进行了比较。分析表明,虽然不带玻璃盖板的PV／T系统的光伏转换效率要比带玻璃盖板系统的高出10％左右,但对风速为5m／s的情况,其热能输出已微乎其微。分析结果还表明,在两种风速条件下,带玻璃盖板的PV／T系统的可用能(Exergy)转换效率ηΣ,2nd均高于不带玻璃盖板的PV／T系统。The simplified output performance analysis of the PV/T system was reported. The comparisoa of the output performance of the PV/T systems with and without glazing cover under different wind speeds （2m/s and 5m/s ）was given. The results showed that although the photovoltaic efficiency of the PV/T system without additional glazing cover is about 10% higher than that of the system with additional glazing cover, the thermal energy output of the former is very little in the case of 5m/s wind speed. The results also show that for both wind speeds, the exergy efficiency of the PV/T system with additional glazing cover is higher than that of the system without additional glazing cover.
