太阳空气集热器与热水器的热性能分析和测试的差别

DIFFERECES BETWEEN THE SOLAR AIR COLLECTOR AND WATER HEATER IN THE THERMAL PERFORMANCE ANALYSIS AND TESTING

总结和推导了常用太阳空气集热器的有用得热的数学表达式 ,分析了 UL、F′、FR 的数学表达式与热水器的异同 ,指出了测试和设计空气集热器时应注意的有关问题。

In this paper a simple model for the useful gain of the solar air collector is derived.The equation of U L、F′、F R in this model was compared with that of the water heater,and the key points for designing and testing of the solar air collector are pointed out.
