摘要:

为研究高温环境中降温服装对人体热舒适的影响,通过出汗暖体假人实验和真人着装实验分别研究了通风服的热湿性能以及对人体热舒适的影响。研究发现:当通风量为0.012 m3/s 时,通风系统的引进使服装的湿阻减小58%。男性受试者穿着通风服在25℃、相对湿度50%的环境条件下运动,其局部皮肤温度、平均皮肤温度均比风扇未打开时低;其中,胸部和腿部皮肤温度降低幅度最为明显;打开与关闭风扇两种实验条件下,受试者的局部皮肤温度以及平均皮肤温度有显著性差异。运动20 min 和休息20 min后,风扇打开时的平均皮肤温度比未打开时分别低2.4、0.9 ℃;研究表明该通风服装可用来作为改善人体热舒适的服装雏形。

Abstract:

In order to investigate the effect of personal cooling clothing on human body thermal comfort, the influence of ventilation clothing used small fans on the evaporative resistance and thermal comfort via sweating thermal manikin and human wear trials. It was found that when the ventilation rate was 12 l/s the evaporative resistance of the clothing was reduced by 58%. The local skin temperatures and the mean skin temperature were much lower when the fans were opened and the subjects exercised in an environment of 25oC, 50%RH, especially the chest and the calf skin temperatures. Significant difference of the local and mean skin temperatures of the male subjects were observed between the fans opened and closed conditions (p<0.05). After exercising 20 mins and resting 20 mins, the mean skin temperature were reduced by 2.4 oC and 0.9 oC respectively, compared with the fans closed condition. The ventilation clothing with the small fans could be used as a prototype for the improvement of thermal comfort.

Key words: ventilation clothing, evaporative resistance, thermal comfort, skin temperature
