Research On Rural Residential Environment In Targeted Poverty Alleviation Areas

To measure the effectiveness of precise poverty alleviation and help rural revitalization,this paper takes Baishuidong Village,a national-level poverty-stricken village in Longhui County,Hunan Province as the research object,conducts actual measurement of the local indoor thermal environment in winter and summer,and conducts a questionnaire survey on local residents.Based on the measured parameters,the thermal sensation model of local residents in winter and summer is established,and the local residents’ satisfaction with the house and living environment is fully investigated,and the infrastructure such as kitchen and toilet is investigated.Compare the same type of research and summarize the differences in clothing thermal resistance and comfort model between Baishuidong and other rural areas.The research results show that the use of heating equipment by residents in winter has a very limited effect on improving the indoor thermal environment.The room temperature in the heating room is only 0.7°C higher than that in the non-heating room,and 2.9°C higher than the outdoor temperature.In summer,the difference of the room temperature and humidity of different functional partitions.is not obvious.The 7 level voting criteria of ASHRAE was used to investigate the thermal sensation,wet sensation and wind sensation of residents in this area.In summer,residents are more accepting of the thermal environment,and have lower expectations for the thermal environment than in winter.In winter,when the existing thermal environment is acceptable,61% of the subjects want the room temperature to increase,and in summer,when they accept the existing thermal environment,55.8% of the subjects want the room temperature to remain unchanged.The proportion of subjects who believed that the wet environment was in a neutral state was higher in summer than in winter.compared with winter,the acceptance of the wet environment in summer was higher The average winter and summer residents’ votes for wind sensations did not differ much.By fitting the existing thermal sensation voting value and operating temperature,the acceptable temperature range and neutral temperature in winter and summer are calculated.The predicted thermoneutral temperature in winter is 12.55℃,the acceptable temperature ranges of 80% and 90% are 10.43～16.68℃ and 11.30～13.81℃,respectively;the predicted thermoneutral temperature in summer is 25.07℃,80% and90% acceptable The temperature ranges were 22.78～27.53°C and 23.67～26.47°C,respectively.The thermal resistance of clothing is analyzed by single factor.The average clothing thermal resistance of Baishuidong Village in winter is 1.24 clo,and the average clothing thermal resistance in summer is 0.36 clo.Compared with other rural areas with hot summer and cold winter,Baishuidong Village has relatively low predicted thermal neutral temperature and average clothing thermal resistance in winter.The temperature and humidity of rooms of different building types are monitored.The temperature and humidity of wooden structure houses are greatly affected by the outdoor environment.The indoor temperature of brick houses does not change significantly with the outdoor temperature,and the indoor humidity is at a lower level than that of wooden structure houses.The temperature and humidity of the main functional rooms of a typical residence are monitored throughout the year.The monthly average maximum and minimum temperatures of the year appear in August and December,respectively,at 26.5°C and 5°C;the annual average monthly maximum and minimum humidity appear in January and August,at 94.5% and 69.7%,respectively.Research on indoor thermal comfort in poverty-stricken areas is of great value for regulating the design of local rural residential buildings,understanding the actual situation of local villagers’ residential thermal environment,and providing theoretical basis for the governance of surrounding villages’ living environment.
