以PV/T集热器为研究对象,从技术、效果及成本特性三方面建立性能评价模型,开展PV/T集热器性能综合评价。结果表明,结构参数、环境气象参数、使用寿命分别对转换效率、输出能量及成本产生较大影响。在一定条件下,太阳电池覆盖率为0.4和0.8时,其等效热效率分别为58.0%和64.5%;太阳辐照度为500 W/m^(2)、800 W/m^(2)时,其输出热量分别为13481 KJ和29005 KJ,设计寿命为10年、20年和30年时,成本分别为3861.00元、4074.80元和4205.76元。研究为综合评价PV/T集热器性能提供了一种新的思路。

Taking the structure of PV/T collector as the research object,the performance evaluation model is established from three aspects of technology,effect and cost characteristics to carry out the comprehensive evaluation of the performance of PV/T collector.The influence of structural parameters,meteorological parameters and solar term on the performance of PV/T collector is studied.The results show that the structural parameters,the link meteorological parameters and the service life have great influence on the conversion efficiency,output energy and cost.Under certain conditions,when the solar cell coverage is 0.4 and 0.8,the equivalent thermal efficiency is 58.0%and 64.5%respectively;When the solar irradiance is 500W/m^(2)and 800W/m^(2),the output heat is 13481kJ and 29005kJ respectively.When the design life is 10 years,20 years and 30years,the cost is 3861 yuan,4074.799 yuan and 4205.76 yuan respectively.This study provides a new way to comprehensively evaluate the performance of PV/T collector.
