Seasonal And Spatial Study On Thermal Comfort Of Rural Residents In Turpan

In Turpan,the climate,architecture and residents’ customs have significant regional characteristics.The climatic conditions of hot summer and cold winter have affected the local vernacular architectural style and residents’ living habits.Rural residents in Turpan alternately use the indoor spaces,semi-open spaces and open spaces of buildings in different seasons and time periods,while indicates the impacts of the season and building spaces on the thermal comfort of residents.Scholars have carried out a large number of human thermal comfort field surveys and studies on a global scale.It is found that residents have different thermal comfort requirements under the differences of regions,seasons and building types,and there are differences in adaptability to the thermal environment.On this basis,the human thermal comfort model under the differences of regions,seasons and building types has been established.However,thermal comfort research under differences in building spaces is relatively scarce in the existing researches.In this regard,this paper conducts field investigations of rural residents in Turpan on human thermal comfort,explores the thermal comfort conditions in different seasons and spaces,and analyzes the influencing factors of human thermal comfort and thermal adaptation.The main findings of this paper are as follows:(1)Through the thermal comfort survey and thermal environment test of rural residents in Turpan,it is found that Turpan’s rural buildings have different thermal environment characteristics in different seasons and different spaces.In summer,the temperature is high,the air velocity is high,and the humidity is low,especially in semiopen spaces.The temperature of indoor and semi-open spaces in the transition seasons is more suitable,while the indoor space in winter is heated by coal stoves and other equipment,and the temperature is higher;Turpan rural residents have different thermal response characteristics in different seasons and different spaces.In summer indoor spaces,residents’ thermal sensation is “slightly warm”,semi-open spaces are “neutral”,and residents’ thermal expectations are “cooler”.In the indoor and semi-open spaces in winter and transitional seasons,the residents’ hot feeling that the voting frequency is "neutral" is the highest,and the thermal expectation that the voting frequency is the highest is "unchanged".(2)Analyzing the thermal response voting of rural residents in Turpan,it is found that rural residents in Turpan have different thermal comfort levels in different seasons and different spaces.In summer,the neutral temperature of residents in indoor and semiopen spaces is 26.6 ℃ and 27.5 ℃ respectively,the preferred temperature is 23.3 ℃ and24.9 ℃ respectively,and the upper limit of 80% acceptable temperature is 32.2 ℃ and34.7 ℃ respectively.In the transition seasons,the neutral temperature of residents in indoor space and semi-open spaces is 23.0 ℃ and 21.9 ℃ respectively,and the 80%acceptable temperature range is 21.9～32.22 and 19.7～29.27 ℃ respectively.In winter,the neutral temperature of residents in the indoor space is 18.3 ℃,the preferred temperature is 23.4 ℃,and the 80% acceptable temperature range is 14.9-29.4 ℃.(3)Rural residents in Turpan have a strong ability to adapt to the local climate,especially in semi-open spaces.There is a significant relationship between the thermal comfort level of residents and the characteristics of the space thermal environment.Local residents not only use common thermal adaptation behaviors such as heating and fan equipment,adding or reducing clothing,but also improve thermal comfort through space selection behaviors in transition seasons and summer,reflecting the effect of thermal adaptation behavior on residents’ climate adaptability.The research reveals the ways to improve the thermal comfort of residents and enhance the thermal adaptability of the building space.It proves that the diverse spaces of Turpan’s vernacular architecture can stimulate the thermal adaptation behavior of the residents,improve the thermal comfort and enhance the thermal adaptability of the residents by creating a complementary thermal environment.This paper draws a series of conclusions based on the on-site investigation and data analysis of the thermal comfort of rural residents in Turpan,grasps the characteristics of thermal response and thermal comfort level of residents under seasonal and spatial differences,and discusses the space of vernacular buildings,human thermal comfort and adaptability and climate The relationship between them helps to understand how vernacular architecture promotes people to adapt to the climate,and provides a basis for the spatial design of vernacular architecture.
