摘　　要：谐波反应法和冷负荷系数法是我国原城乡建设环境保护部主持通过的两种空调冷负荷计算方法,本文的目的是找出两者的差异性和适应性以指导工程实践.文中采用对比分析的方法,分别用两种方法的工程简化算法对位于哈尔滨、北京、上海及广州的某办公建筑形成的冷负荷进行了计算,并对两种方法算得的各项冷负荷逐时值和总逐时值进行了对比分析.得出：冷负荷系数法和谐波反应法存在峰值、峰值出现时间均不同的规律;冷负荷系数法的峰值要比谐波反应法大5~7 W/m2;而且冷负荷系数法算得的各地区峰值均出现在12h左右,而谐波反应法峰值均是在18~20 h左右.Harmonic responses method and cooling load factor method are the two cooling load calculation methods which adopted by former Urban and Rural Construction and Environmental Protection Ministry.The study was carried out to analyse the difference and adjustability between harmonic responses method and cooling load factor method to guide en-gineering practice.The simplified calculation methods of these two methods were adopt to calculate the building cooling loads by analyzed and contrasted in an office building which located in Harbin,Beijing,Shanghai and Guangzhou respec-tively,and made comparative analysis on the various hourly cooling load and total loads.The analysis results showed that the peak value and the presented time of those peak values were different by these two methods.The peak value cal-culated by cooling load factor method in each district were 5 ~ 7 W/m2 higher than by harmonic responses method and the present time of the peak load by cooling load factor method was 12： 00 while the harmonic responses method was about 18： 00 ~ 20： 00 or so.
