ABSTRACT
The medical surgical mask (MSM) has been the essential protective equipment in people's daily work. experimental purpose is to explore effects of wearing MSM on human thermal sensation, comfort, and breathing comfort office buildings summer. A total 30 healthy college students were recruited for testing. experiment was carried out a climate chamber, which can simulate collects subjects' skin temperature, microclimate mask, subjective votes, including sensory votes (TSV), (TCV), respiratory (BCV). Experimental results show that no significant effect temperature body. inside reaches over 34℃, relative humidity 70%. high-temperature high-humidity put beings an uneven environment, leads poor tolerance environment becomes main reason destroying comfort. Wearing impact body, more as environmental increases. Once taken off, body will enter extremely comfortable resulting excessively high vote value. difference voting values before after removing larger with temperature. By fitting perform data processing, it be found reduce neutral by 1.5°C, optimal 1.4°C, increases, discomfort become intense. Regardless whether MSM, subjects preferred slight warmer environment. In conclusion, increase ambient cause worse this disturbance
