工位辐射供暖末端对人体局部及整体热感觉的影响
Influence of workstation radiant heating terminal on local and overall thermal sensation of human body
摘要：
将辐射供暖末端与工位相结合，组成一种新型个性化舒适系统。为了探索工位辐射末端的供暖效果，通过实验收集了24名受试者在不同环境温度下的局部与整体热感觉，并与传统空调环境进行对比。实验结果表明：当环境温度偏离舒适温度区间时，工位辐射末端能有效地提升受试者的热感觉；使用工位辐射末端后，受试者上肢和下肢热感觉改善明显，躯干热感觉变化不大；在16 ℃的环境下，受试者整体热感觉也能达到热中性。工位辐射末端在保证人体热舒适的同时，拓展了舒适温度区间。
Abstract：
Proposes a new type of personal comfort system combining radiant heating terminals with workstation. To explore the heating effect of radiant heating terminals, collects the local and overall thermal sensations of twenty-four volunteers at different ambient temperature by experiments, and compares them with those in the traditional air conditioning environment. The results indicate that radiant heating terminals significantly improve the volunteers’ thermal sensation, when the environment deviates from the comfortable temperature range. The thermal sensations of upper and lower limbs are improved significantly, but the body’s thermal sensation does not change much, when using workstation radiant terminal. The average vote of overall thermal sensation at 16 ℃ is at the neutral level. The workstation radiant heating terminal expands the comfort temperature range while ensuring the thermal comfort of the human body.
