The Study of Arithmetic about the Temperature of a Connected-greenhouse

根据热平衡方程,结合重庆地区的温室结构和气候特点,对冬季温室升温温度估算进行了研究,提出了温室升温估算系数ζ,并对某一结构的温室计算出其值。根据温室升温估算系数ζ,利用数值分析中的曲线拟和,对该温室升温估算系数ζ与室外温度to建立了关系式。根据该关系式和相应的热平衡式,可以计算出室内温度ti。实验证明,该估算方法简单,计算出来的温度数据精度高,具有较高的实际应用价值。

This paper studied a kind of arithmetic for calculating approximately the temperature of winter in a connected-greenhouse based on the heating balance equation, the structure of greenhouse and the climate in Chongqing. Then, the temperature of a greenhouse for warming calculating coefficient ζ was put forward, and the ζ was calculated based on a kind of greenhouse in Chongqing. Based on theζand curve drawing up, a relational model was found between theζ and outer temperature to in greenhouse, then, the inter temperature ti could be calculated by the relational model and correspond heat balance equation. It was proved that the arithmetic was simple and the calculated result was precision. So the arithmetic could demand the need of application in reality.
