Abstract:
Objective To explore the characteristics of human thermal response in the natural cold environment.Methods Investigated and contrasted the skin temperature,thermal response characteristic and thermal comfort results of five women and fifteen men,aged 20 to 32 years,5 to 8 years of local living,in indoor warm environment and outdoor natural cold environment in the end of November,2007,in suburb of a city in Sinkiang(height 1 600 m,the lowest outdoor temperature in winter is-25℃ and the highest outdoor temperature in winter is 5℃,indoor average temperature is 18℃).The measurement on site and questionnaires were used.Results The mean thermal comfort vote(MTCV) mostly distributes around-3(mostly uncomfortable) when the outdoor temperature is-4.3--5.0 ℃,relative humidity is 65.2%-66.7%,The mean thermal sensation vote(MTSV) is-1.5(clod) to-3(quite cold).Human body could appear different degree of cold intensity sense and the body could not help quivering.Noses,ears and hands appeared different degree of rose color.Eyes became dryness and weep after staying long time outdoor.Conclusion Temperature,relative humidity and wind speed all around affected the mean thermal sense vote value and mean thermal comfort vote value.In the environment of low temperature,humidity and wind speed could increase the intension of cold action.Human is more sensitive to cold sense than thermal sense.
