摘　　要：结合夏热冬暖地区的气候特征,建立了一间洁净室的物理模型,采用谐波反应法对净化空调系统逐时冷、湿负荷进行了数值计算,分析围护结构和空气处理过程对冷负荷的影响,并将模型计算结果与实际工况进行了对比验证.结果表明:外遮阳装置的节能潜力较大,室内逐时冷负荷下降幅度最大可达13.6%;相同外界条件下,与一次回风处理过程相比,独立新风系统节能效果明显,节能率最大可达38.3%;与测试结果比较,冷负荷计算值平均误差为10%,表明所建立的模型可靠.According to the characteristics of the climate in a zone with hot summer and warm winter,a physical model of a clean room was built.Then,based on the harmonic response method,a numerical calculation of the hourly cooling and moisture load in the modeled clean room with a clean air conditioning system was carried out. Moreover,the effects of the building envelope and the hydrothermal process on the hourly cooling load were ana-lyzed,with the results being finally compared with the actual operation data.It is found that （1 ）the exterior win-dow shades are of great energy-saving potential,with an indoor hourly cooling load reduction being up to 13.6%;（2）under the same external conditions,the dedicated outdoor air system is superior to the primary return air sys-tem,with a maximum energy-saving rate being up to 38.3%;and （3）the average calculation error of cooling load is only 10%,which means that the established physical model is reliable.
