摘　　要：讨论了办公建筑空调系统中的辐射地板、辐射天花和对流换热3种不同的供冷末端在人体整体热感觉和局部热感觉方面的特征与差异。对3种不同供冷末端下的办公建筑进行现场热舒适调研测试,发现3种末端的中性温度相差较小,且辐射地板供冷系统的中性温度最高。通过对局部热感觉投票结果分析发现,3种末端的局部热感觉差异显著,辐射地板和对流换热供冷末端的局部热感觉有明显的“分层现象”。对流换热系统的上肢部位热感觉明显偏低,而辐射地板系统的下肢部位更容易产生冷感。对问卷中整体热感觉偏冷的人员分析发现,相比于对流供冷末端两种辐射末端的局部热感觉对整体热感觉的影响更显著。The study mainly discussed the features and differences of overall and local thermal sensation between three different types of air conditioning ends which contained radiant floor,radiant ceiling and convection system,based on the field survey test results of these three different types of air conditioning ends.By comparing its features and differences in local thermal sensation,the research appeared that radiant floor and convection systems had significant thermal sensation stratification.Under the radiant floor system,workers felt that legs are colder than other parts and it became arms under the convection system.This study also analyzed the people whose overall thermal sensation was cold in the questionnaire,and found that the local thermal sensation of the two radiation ends had a more significant influence on the overall thermal sensation compared with the convective cooling end.
