样本数量对住宅空调能耗调查准确性的影响研究
Influence of sample number on accuracy of air conditioning energy consumption survey in residential buildings
摘要：
如何合理确定调查样本的数量是住宅空调能耗调查工作中亟待研究解决的一个重要基础性问题。依据北京市和武汉市大量住户的空调能耗调查数据，采用随机抽样试验的方法，对调查样本数量与调查准确度的关系进行了研究。结果表明，对于大量住户的空调能耗调查，为了达到较高的调查准确度，北方寒冷地区随机抽样调查的样本数不宜少于140户，南方炎热地区随机抽样调查的样本数不宜少于100户。这些研究结果可供住宅空调能耗调查和其他类似调查工作参考。
Abstract：
It is an important basic problem to be urgently studied and solved in residential air conditioning energy consumption survey how to reasonably determine sample number. Based on a great deal of the survey data of residential air conditioning energy consumption in Beijing and Wuhan, the relationship between the accuracy and the sample number is studied with the method of random sampling test. The survey results show that as to an air conditioning energy consumption survey of large numbers of households, in order to achieve higher investigation accuracy, the sample quantity should not be less than 140 households for cold zones in north China or 100 households for hot zones in south China. The results provide a reference for the surveys of residential air conditioning energy consumption and other related surveys.
