Study On The Thermal Comfort Characteristics Of Residents In The Farming And Pastoral Areas In Central And Southern Inner Mongolia

Traditional houses in farming and pastoral areas were built earlier,mostly based on their own architectural experience.Residents’ satisfaction is not high.With the state’s support for the “Three Agriculture,Three Animal Husbandry” policies,local governments have built a large number of people’s livelihood projects in recent years,focusing on improving agriculture.The living conditions of the herdsmen.Affected by geographical and climatic conditions,the thermal comfort characteristics and subjective feelings of farmers and herdsmen are directly related to indoor and outdoor environmental parameters.Analyzing the thermal adaptability of the residents in the farming and pastoral areas,establishing a thermal comfort model suitable for farmers and herdsmen in central and southern Inner Mongolia,and improving the indoor thermal comfort level of the residents in the farming and pastoral areas is particularly important.This topic selects the rural dwellings,brick dwellings,and civil engineering dwellings in the farming and pastoral areas as the research objects,using a combination of on-site tracking tests and subjective questionnaires,based on three indoor and outdoor thermal environment parameters of dwellings,and the thermal perception of agricultural and pastoral democracy.And other data,analyze the indoor vertical air temperature difference,clothing thermal resistance value,environmental temperature expectation and other parameters of the three residential buildings in the transition season,summer and winter,and study the effect of residential indoor and outdoor thermal environment parameters on the thermal comfort of the human body.It was found that the vertical air temperature difference between the dwellings in the raw soil was the smallest in summer and winter,and the vertical air temperature difference in the residential construction of the civil engineering was the smallest in the transition season;the survey of the adaptation behavior of the residents in the farming and pastoral areas in each season found that the clothing adjustment is the main means for the residents to change the thermal comfort.The thermal resistance of clothing in the transition season,summer and winter is concentrated in the range of 0.6～1.0clo,0.4～0.8clo,and 1.0～1.4clo respectively;the investigation of the thermal expectations of the residents in farming and pastoral areas on the indoor environment temperature shows that the thermal resistance of each residential house is Interviewers have “unchanged” expectations of ambient temperature during the transitional season and summer,which accounted for the main proportion.In winter,“increased”expectations of ambient temperature and heat accounted for the main proportion.Residents feel cold indoors in winter and expect the ambient temperature to rise.Analyze the relationship between indoor air temperature,predicted average thermal sensation index(PMV)and measured average thermal sensation index(MTS)of the three residential houses in each season,and establish the fit between it and PMV and MTS using operating temperature as the thermal comfort evaluation index relationship.Obtain the measured thermal neutral temperature and predicted thermal neutral temperature of the human body in the agricultural and pastoral areas of central and southern Inner Mongolia.In the transitional season,the measured thermal neutral temperature and predicted thermal neutral temperature of the native soil residence are 15.9°C and 18°C,the brick residences are 16.6°C and 18.5°C,and the civil engineering residences are 18.8°C and 20°C.The residential houses of the people’s livelihood project have the highest temperature.The measured thermal neutral temperature and predicted thermal neutral temperature obtained in summer residential houses are 24.5°C and 23.8°C,in brick houses are 26.4°C and25.7°C,in civil engineering houses are 24.2°C and 24.6°C,bricks and tiles The residential houses have the highest temperature.The actual measured thermal neutral temperature and predicted thermal neutral temperature obtained in the raw soil dwellings in winter are15.2°C and 16.8°C,respectively,the brick dwellings are 14.8°C and 16.2°C,and the civil engineering dwellings are 17.8°C and 18.8°C.The civil engineering The residential houses have the highest temperature.The living habits of residents in farming and pastoral areas are closely related to outdoor temperature.The relationship between the neutral temperature of residents and the outdoor ambient temperature is discussed.Through theoretical analysis and numerical analysis,it fits the 80% and 90% acceptable temperature ranges of local residents,and establishes a suitable temperature range for Inner Mongolia.The thermal comfort model in the southern agricultural and pastoral areas found that farmers and herdsmen in this area have a larger acceptance range for lower temperatures,and the acceptable temperature range for higher temperatures has narrowed.Residents in severe cold areas have higher adaptability to colder environments and greater acceptance.It can provide a reference for the research on the thermal comfort of the residents in the farming and pastoral areas in central and southern Inner Mongolia.
