热湿工况下工位辐射空调的热舒适实验研究

Experimental analysis of thermal comfort in the hot-humid environment with radiant panel workstation

为研究热湿工况下使用工位辐射空调的人体热舒适情况,在人工环境实验室内,通过改变环境背景温度来影响人体的热感觉,并采用热感觉投票(TSV)作为评价标准,重点研究了人体头部、躯干、上肢、下肢以及整体热感觉情况。实验结果表明,尽管背景环境参数超出舒适范围,但使用工位辐射空调能维持受试者的舒适状态,即背景温度稳定在28℃时,平均整体热感觉投票值低于+0.2;背景温度为30℃时,受试者热感觉仍能满足ASHRAE规范中规定的80%可接受范围要求。

This study focuses on thermal comfort of subjects with radiant panel workstation in hot-humid environment. The experiments are carried out in the experimental chamber. Thermal sensations of whole body, head, trunk, upper limb and lower limb of subjects are collected on the basis of seven-scale vote. The obtained results indicate that the average vote of thermal sensation at 28 ℃ is lower than ＋0. 2, and subjects could maintain comfortable condition well with radiant panel workstation （within the 80% acceptable range of ASHRAE Standard） although indoor environment is as high as 30 ℃. This study provides a new way for both extending comfortable temperature range and saving energy in buildings.
