双层集热棚式太阳能热气流发电装置研究

Preliminary Research on Solar Power Plant Chimney with Double Heat Collectors

为解决传统温室大棚在保温和降湿方面存在的问题,扩大太阳能热气流发电应用范围,本文提出一种基于温室大棚的双层集热棚式太阳能热气流发电装置。给出了夏冬两季不同运行模式,同时对双层集热棚采光性进行计算和分析,结果表明,主集热棚内平均单位面积的太阳净辐射量为599.76W/m2,次集热棚内平均单位面积的太阳净辐射量为539.784W/m2,双层集热棚平均透光率为69.2%,符合国标规定的温室大棚光照要求,满足大棚夏季降温、降湿,冬季保温、降湿的要求,本研究可以实现太阳能发电和改善温室大棚作物的生长环境,具有一定的推广应用价值。

To solve the problems and expand the scope o{ solar power plant chimney applications, this paper proposes a solar power plant chimney with double heat collectors based on greenhouse. Different operation mode are given for summer and winter and expound the principle of power generation and air humidity re- ducing. Meanwhile, through theoretical analysis and calculation, the results show that the main heat collection average net radiation of the sun is 599.76 W/m2 as per unit area, the second heat collection average net radiation of the s collectors is 69.2%, W is 539. 784 W/m2 as per unit area, and the average transmittance of double heat hich meet the national standard. This device can realize the solar power generate
