摘要
玻璃温室供暖热负荷对于玻璃温室冬季环境控制至关重要。利用EnergyPlus软件进行玻璃温室供暖热负荷计算,根据温室使用需求确定供暖室内计算温度,利用典型气象年数据确定室外计算温度,建立模型并计算山东省青岛市某玻璃温室12月至次年1月的供暖热负荷,分析玻璃温室供暖热负荷影响因素。结果表明:与双层中空玻璃幕墙相比,以单层玻璃幕墙为围护结构的温室,总供暖热负荷多50.58%;以双层中空玻璃幕墙为围护结构的温室,室内计算温度每升高1℃,总供暖热负荷增加5.16%。研究结果为玻璃温室冬季供暖系统的设计和运行提供依据。
The heating load of glass greenhouse is very important for the environmental control of glass greenhouse in winter.EnergyPlus software was used to calculate the heating load of the glass greenhouse,determine the indoor calculated temperature according to the demand of the greenhouse,determine the outdoor calculated temperature based on the data of typical meteorological year,establish a model and calculate the heating load of a glass greenhouse in Qingdao,Shandong Province from December to January of the next year,and analyze the factors affecting the heating load of the glass greenhouse.The results show that the total heating load of greenhouse with single-layer glass curtain wall as the building envelope is 50.58%higher than that of double-layer insulating glass curtain wall.For the greenhouse with double-layer insulating glass curtain wall as the building envelope,the total heating load will increase by 5.16%for each 1℃rise in the indoor calculated temperature.The research results provide a basis for the design and operation of the heating system of the glass greenhouse in winter.
