上海地区温室冷热负荷特征分析

Analysis of load characteristics of conventional crops in facility agriculture in Shanghai

目前针对温室空调系统的设计,常通过理论公式或数值模拟计算,缺少估算用冷热负荷指标值,对冷热负荷特征的分析也少有研究。文章以上海地区设施农业常规作物类型和常用温室类型的组合为研究对象,采用DeST软件模拟计算不同组合下温室的冷热负荷,分析其负荷特征,提出不同组合下温室冷热负荷指标参考值,为设计温室空调系统提供设计参数和计算方法。

The design of greenhouse air conditioning systems often relies on the calculations of theoretical formulas or numerical simulations.There is a lack of heating and cooling load indicators for estimation and research on analyzing load characteristics is also limited.This paper focuses on the combination of conventional crop types and common greenhouse types of facility agriculture in Shanghai.The DeST software is used to simulate and calculate the heating and cooling loads of the greenhouse under different combinations,analyse their load characteristics,and propose reference values for heating and cooling load indicators under different combinations.This provides design parameters and calculation methods for designing greenhouse air conditioning systems.
