2019年冠状病毒病(新冠肺炎)暴发后，个人在室内和户外佩戴口罩保护自己的方式受到了极大的重视。然而，佩戴口罩会影响人体与环境之间的热湿交换，进而影响人体的热舒适性，造成不适，导致人们佩戴不科学、不规范，影响人们的健康生活。因此，为了分析口罩对人体热舒适性的影响，广州大学在室外进行了参数测量和实地调查，调查了戴口罩行人在户外的热舒适性。在本研究中，选择生理当量温度(PET)作为热舒适性评价指标。在现场调查的基础上，确定了佩戴口罩和不戴口罩的受试者的中性PET和首选PET。结果表明，戴口罩的人的中性温度略低于不戴口罩的人，戴口罩的人需要较低的环境温度才能感觉舒适。在总数中，戴口罩会增加面部的热感，并导致面部不适。此外，初步评价了PET对戴口罩人群的适宜性。
After the outbreak of coronavirus disease 2019 (COVID-19), individuals have paid significant attention to protecting themselves indoors and outdoors by wearing masks. However, wearing masks can affect the exchange of heat and moisture between the body and the environment, which in turn affects the thermal comfort of the body and causes discomfort, leading people to wear them in an unscientific and standardized manner, affecting people's healthy lives. Thus, to analyze its effects on thermal comfort, outdoor parameter measurements and field surveys were conducted at Guangzhou University to investigate the thermal comfort of pedestrians wearing masks outdoors. In this study, the physiological equivalent temperature (PET) was chosen for thermal comfort evaluation. Based on the field survey, the neutral PET and preferred PET of the subjects with and without masks were determined. The results indicated that the neutral temperature of people wearing masks are slightly lower than that of people without masks, and people with masks need a lower ambient temperature to feel comfortable. Out of the total, wearing masks raised the heat sensation in the face more and caused discomfort to the face. In addition, the suitability of PET for the people with masks was initially evaluated.
