摘要: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、躯千、上肢、下肢以及整体热感党情况。实验结果表明,尽管背景环境参数超出舒造范国,但使用工位辐射空调能维持受试者的舒造状态,即背景温度稳定在28C时,平均整体热感党投票值低子十0.2;背景温度为30C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。

Abstract: 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 C is lower than +0. 2, and subjects could maintain comfortable condition well with radiant panel workstation (within the 8o% acceptable range of ASHRAE Standard) although indoor environment is as high as 3o 'C . This study
provides a new way for both extending comfortable temperature range and saving energy in buildings. Keywords: thermal sensation; thermal comfort; environmental parameter; radiant panel workstation
在传统空调环境中,即使温湿度在舒适区间内,建筑中的人仍会抱怨其所处的室内环境]。许多研究已经证实,相比传统的空调系统,辐射空调系统不仅能创造更舒适的室内环境,还具有节能优势(1-4)。
