摘要: 引入热通量概念对温室的保温蓄热性能进行评价,通过对比观测对热通量和室内外气象因子的相关性进行了分析。结果表明,总辐射、温室内外温度和热通量相关性较高,但室外温度升降转换的时间比热通量延迟了2~3 h;室内相对湿度对热通量有负调节作用,并且夜间作用小于白天,室外相对湿度夜间达到稳定状态比热通量延迟近2 h,在这期间对热通量的影响很小;室外风速是热通量的一个主要影响因子,但热通量具有较高的稳定性。

Abstract: Introducing the concept of heat flux to evaluate heat preservation and storage performance of solar greenhouse, by comparing the observation of correlation between heat flux and meteorological factors to analyze, and the results show thatthe correlation between total radiation and indoor and outdoor temperature of the greenhouse and heat flux is higher,but the outdoor temperature has a nearly 2~3 h delay to the heat flux on rising and dropping time; indoor relative humidity is a negative regulatory role for heat flux, and the effect is less than it during the day, outdoor relative humidity delays nearly 2 h to heat flux on reaching a steady state, and it has a little impact on the heat flux during night; outdoor wind speed is a major factor on heat flux, but it has a lower stability than heat flux.

Key words: solar greenhouse, envelope, heat flux, meteorological factors
