Abstract:In the Midwest of Inner Mongolia agriculture herdsman residential building field research and life, and the thermal comfort of indoor temperature and field measurement, statistical analysis, farmers and herdsmen are mainly distributed in residential buildings in winter indoor temperature 10 ℃ ~ 16 ℃, the temperature is generally low, the majority of farmers and herdsmen feeling slants cold, this to ensure the health of farmers and herdsmen and comfortable, improve their quality of life, we still have some gap.Through in-depth study on the relationship between thermal sensation and indoor temperature, thermal resistance of clothing, metabolic rate and age, it is concluded that the indoor acceptable temperature range in winter for residential buildings of farmers and herdsmen in central and western Inner Mongolia is 13.63 ℃ ~ 21.66 ℃, the expected temperature is 19.38 ℃, and the thermally neutral temperature is 16.09 ℃. This conclusion is of great significance to the in-depth study on the indoor thermal comfort of farmers' and herdsmen's residential buildings in winter, to provide the basis for the heating temperature of farmers' and herdsmen's residential buildings in winter and to improve their living quality.
