我们对平板式太阳能空气加热器进行了分析试验,并设计了一个模型来预测其空气质量流速和对有效能量的吸收能力。模型与实验数据表现了良好的一致性。这种装置的缺点是数据分散、效率低,但低效却可被其结构简单和价格低廉所弥补。
We conducted an analytical test on a flat panel solar air heater and designed a model to predict its air mass flow rate and its ability to absorb effective energy. The model and experimental data show good consistency. The disadvantage of this kind of device is that the data is scattered and the efficiency is low, but the inefficiency can be compensated for by its simple structure and low cost.
