基于空间分布的暖通空调负荷计算室外计算温度参数确定方法

摘要

暖通空调设计室外计算温度参数是供暖空调计算负荷的重要依据,但现行规范只提供了294个站点的室外计算温度参数,难以满足工程需求.以现有的设计气象参数为基础,采用统计分析的方法,结合空间插值方法,提出了拟合方程计算值叠加残差的计算参数确定方法,并进行了交叉验证.对于无室外计算温度参数的站点,用该方法计算得到的设计计算温度具有相对较高的精度.%Outdoor air design temperature is important to HVAC heating and cooling load calculation.But the current codes provide outdoor air design parameters of 294 sites only,which cannot meet the practical requirements.Based on the existing design meteorological parameters,proposes a method of statistical analysis combined with spatial interpolation method.The results show that for the site without outdoor air design parameters,the calculated temperature obtained by this method has relatively high precision.
