摘　　要：以'26℃空调节能行动'为研究背景,对定温控制空调系统从舒适性和节能性两方面进行分析.通过测试分析对比不同朝向但相连通的两间房间的PMV值,说明控制室内温度相同时,由于平均辐射温度不同,房间的舒适度不同.采用相同的温度控制标准往往导致某些区域舒适性差.对比分析了夏季和冬季定温度控制和定PMV指标控制空调系统的节能性差异,说明定温度控制既不体现热舒适性也不体现节能性,而定热舒适指标(如PMV)控制,则是空调系统保证舒适性兼顾节能的有效途径之一.By taking “26 ℃ air conditioning energy conservatton motion” as the research background, this paper analyzed the comfort and energy-saving performance of temperature control air-conditioning sys- tem. Then, a comparison of the Predicted Mean Vote （PMV） values of two connected rooms in different orientations revealed that, at the same temperature, different average radiation temperatures caused differ- ent comfort indexes. The same temperature control standard usually resulted in uncomfortable environ- ment. The energy-saving differences between the temperature and the comfort index control of air condi- tioning system in summer and winter were analyzed, which illustrated that the temperature control embod- ied neither heat comfort nor energy-consumption, and comfort index control, like PMV index control, is one of the effective methods which ensures comfort and considers the energy-saving requirement of air con- ditioning system.
