Research On Thermal Environment Of Traditional Dwelling Under The Dry-hot And Dry-cold Zone

Most of the thermal norms and standards are developed for urban buildingspresently. There is little research on indoor thermal environment of residential buildings，less about the remote. The overall living standards are lower for the rural populationliving in dry-hot and dry-cold areas，who are always living with many other nations.Therefore，the studies about these areas have very important significance for new ruralconstruction in our country. According to the research of the thermal environment wherethe Turpan live，the study obtains the measured data analysis about such areas，in orderto investigate energy-saving potential for the housing of the region. Based on thethermal comfort theory, The paper analyzes are the thermal comfort situation of therural residents under this type of climate，then get the temperature model that the bodycan adapt to in this area, and meanwhile make suggestions about building climatedesign principles.Through the paper research, draw the following results:1) In dry-hot and dry-cold areas, half outdoor space summer daytime highesttemperature is lower than the highest temperature outdoor5-10or so, and night isclose to outdoor air temperature, cloudy and rainy weather for outdoor and half outsidetemperature influence is greater than the interior of the retaining structure, sealing andheat storage moisture absorption ability in this weather plays a negative role. Winterheating room temperature distribution in most time between10and20, temperaturefluctuation depends on personnel’s work and rest habits and the frequency of usingfire-Kang frequency. Not heating room temperature was kept-10-0or so, havecertain cyclical fluctuation effect, but changing trend gently;2) In summer of dry-hot and dry-cold areas, Relative humidity and the environmentinsulation, heat storage, personnel activities, ventilation effect are related. The higher the temperature, evaporation effect will be more significant, the air humidity will belower. Environment of heat insulation, heat storage function helps moisturizing andmoderate humidity change. The adjustment of personnel activities of relative humiditythan the influence of the temperature of air is more obvious. Ventilation effect canreduce indoor outside humidity gap. Winter outdoor air relative humidity andtemperature change is closely related to the higher the temperature, relative humidity islower, no artificial regulation not heating room, the temperature is relative to the size ofthe indoor humidity main factors;3) The rural population living in dry-hot and dry-cold areas have strong ability tothe hot environment, and relatively weak. In summer, when wind speed is smaller, andneutral temperature is Tn28.3，the comfortable temperature limit is Tmax31.8,which are far more higher than the existing model predicted results. In winter, theneutral temperature is Tn19.1，the comfortable temperature limit is Tmin10.3,which are approached to the existing model predicted results.Finally, the paper draws on the outstanding design concept of traditional houses indry-hot and dry-cold climate zones. The design strategies are summarized respectivefrom the base planning and design, architectural design and natural resource to improvethe region’s residential thermal environment design strategies, and the varies strategiesapplication potential are verified by comparing simulation of different optimizationprograms.
