Abstract

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
