| 摘 要： | 建筑空调的全年能耗分析以及空调系统的动态模拟,都需要输入全年逐时气象数据.作者在构成“建筑空调能耗分析用气象资料”时,采用气象站每天八次的定时观测气温值,用样条函数方法插值确定逐时室外温度值.本文对样条函数插值方法,以及端点条件对插值误差的影响进行分析,井介绍减少插值误差的方法.

| Abstract: | It is necessary to input the hourly meteorological data in order to analyze building annual energy consumption and to simulate dynamically air-conditioning systems.The hourly outdoor temperature constituted by cubic splineinterpolation when forming meteorological data is used for building energy anal-ysis.This paper analyzes the theory of spline function interpolation errors affe-cted by boundary conditions and introduces the methods to decrease interpolationerror. |

| Keywords: | cubic spline interpolation interpolation error meteorological data the hourly outdoor temperature building energy analysis |
