定温控制空调系统的舒适性及节能性分析

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.

Analysis of Comfort and Energy-consumption on Temperature Control Air-conditioning System

By taking "26 ℃ air conditioning energy conservation motion" as the research background,this paper analyzed the comfort and energy-saving performance of temperature control air-conditioning system.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 different comfort indexes.The same temperature control standard usually resulted in uncomfortable environment.The energy-saving differences between the temperature and the comfort index control of air conditioning system in summer and winter were analyzed,which illustrated that the temperature control embodied 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 conditioning system.
