Research On Energy Consumption Mode And Thermal Environment Improvement In Villages And Towns In Hilly Areas Of Sichuan

In recent years,the energy crisis and energy conservation have become urgent issues in China.In China's construction industry,with the rapid development of urbanization driven by the continuous expansion of China's construction industry,China's building energy consumption is also increasing.In all villages and towns of our country,the total energy consumption of residential products in villages and towns has increased significantly while the population of villages and towns has decreased.The average energy consumption per household in the country has been consistent with that of urban households,and even More than the trend of the town.However,high-energy-consuming villages and towns do not bring good household experience to the residents of the villages and towns.Therefore,it is imperative to study measures to improve the thermal environment of villages and towns as far as possible under energy saving.The building thermal environment improvement strategy has a close relationship with the local climate.Therefore,the author study on it which is selected based in combination with the thermal climate division and the specific geographical environment.It is located in the Enyang District of Bazhong in the hilly area of Sichuan in the hot summer and cold winter climate zone.Before studying the thermal environment improvement measures for residential houses in towns and villages,we must first understand the energy use patterns of the village residents.The author selected Enyang Town,Liulin Town and Xinglong Town as the research sites.They represent the different developments of all the villages and towns in Enyang District.Therefore,it can reflect the current status of building energy and indoor thermal environment in the villages and towns of Enyang District.In the actual research,the author used field survey and field measurement methods to take the building houses which is built from 2000' to the present as the goal to learn more about the basic conditions and the energy equipment of the building,summer cooling and winter heating measures and the equipments' usage habits.Energy consumption of various types of energy.In addition,the author also conducts thermal and physical parameters measurement research on residential houses in the four seasons.in order to further study,the author especially conducted continuous measurement of temperature and relative humidity in summer and winter for selected typical houses.Through actual investigation and actual measurement,the author found that the average indoor relative humidity of the local villages and towns exceeded 60%;the indoor temperature of the bottom layer was the most comfortable but very humid one,the temperature of the top layer was the highest one,and the temperature of the middle layer was the lowest one;Residents generally only pay attention to summer cooling insulation and ignore winter heating protection.And the worst effect of winter heating protection is the buildings built from 2000 to 2006.Then,the author proposes a corresponding improvement strategy for typical houses,and uses DeST to carry out simulation verification.Finally,the strategy for improving the indoor thermal environment of residential houses in Enyang District is obtained.
