用样条函数构成室外逐时温度的插值方法及其误差估计
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.
