温室冬季覆盖保温层时间的优化研究

Optimization study on covering time of insulation layer for greenhouse in winter

以西安地区某温室为例,通过分析温室全年室外温度特点,利用DeST能耗模拟软件得出温室覆盖保温层的时间规律。根据西安地区典型年的逐时负荷变化,在历年平均不保证7天的情况下,利用温室覆盖保温层的时间规律计算得到冬季温室热负荷,与利用传统计算方法得到的热负荷相比,可以节省辅助热源近13.7%的热耗,达到节能的目的。

Taking one greenhouse in Xi an as example,through analyzing the annual outdoor temperature,by using DeST energy simulation software,the covering time of insulation layer for greenhouse is obtained.According to the hourly load change of the typical year in Xi an,under the condition of no guarantee for seven days on average for calendar year,the heating load of the greenhouse in winter is calculated based on the covering time of insulation layer for greenhouse.Compared with the heating load obtained by the traditional calculation method,the energy consumption of auxiliary heat source can be saved by 13.7%,which achieves the purpose of energy-saving.
