Field Study On Thermal Comfort Of People From Different Regions In Non Air-conditioned Environment

At the present stage,it is of great significance to explore the rules of action between human and nature,environment and climate,to seek for the breakthrough point of building energy conservation,to formulate reasonable building environmental standards and to reduce the unnecessary building energy consumption.The field study of thermal comfort and thermal adaptation can effectively reflect the interaction between human beings and environment,and can immediately respond to the thermal comfort situation.China has a vast territory,there are great differences between the north and south,there is cold winter in the north and long summer heat in the south,and great differences exist in climate.This paper selects the teaching building and students of a university in Hainan as the research object for a year in succession.According to the subjects' common residence,they can be divided into Hainan area,central heating area and non-centralized heating area.To study the regularity of thermal comfort and adaptability of people from different regions in Hainan,and compare the differences of adaptability of people from different regions in Hainan and to explore the effects of adaptive behavior regulation and gender of different regions on thermal comfort in different areas.The results showed that the thermal comfort and adaptive behavior of subjects from different regions were affected by their thermal experiences.The thermal neutral temperature of the subjects in Hainan area is 26.30? C,and the 80%acceptable temperature range is 24.4?28.2?;the thermal neutral operating temperature of the subjects in the central heating area is 25.4?,and the 80%acceptable temperature range is 22.3?27.5?;the thermal neutral operating temperature of the subjects in the non-central heating area is 25 ?,and the 80%thermal acceptable temperature range is 22.8?27.2?.At the same time,the statistical method was used to calculate that there were significantly difference in thermal sensation,humid sensation and clothing insulation between the subjects living in Hainan area and those in central heating area.Subjects in different regions also have certain rules in adaptive behavior regulation mode affected by their thermal experiences.There is a significantly difference in thermal neutral temperature between different gender subjects.The thermal neutral temperature of females is 25.3?,and the 80%acceptable temperature range is 22.8?28.0 ?.The male's thermal neutral operating temperature is 25.0?,and the 80%acceptable temperature range is 22.4?27.2??.The conclusion of this study can perfect the database of thermal comfort research in thermal experiences in China.
