The Northern Rural Residential Energy-saving System Integration And Analysis

With the rapid development of our economy,energy consumption greatly increased,Among them,building energy consumption accounts for about 20%of the total energy consumption,rural construction area accounting for 60%of the national total,rural building energy consumption accounted for a large proportion(heating,cooking energy consumption accounted for most of the annual energy consumption),the rural area of North China is particularly significant.In order to better solve the problem of high energy consumption for heating in rural areas,in-depth and extensive researches have been carried out in rural areas,which includes understanding the residential building framework,energy use,forms of heating system and indoor thermal comfort.According to the investigation,it finds out that nearly six years of buildings reached about 40%,building envelope insulation measures is imperfect,heating mode is single and the traditional heating mode is still used,clean energy almost has not be applied,the indoor comfort is poor,coal and firewood are main fuel in heating.At the same time,the common way of rural heating system has been mastered.Solved the problem of rural building energy consumption,vigorously promote the use of renewable clean energy and energy-saving materials in rural areas,which is important to solve the rural area of our country energy consumption and promote renewable energy use and environmental protection.In order to reduce the energy consumption for heating,seven kinds of integrated heating mode suitable to the rural residential building have been designed which based on the new idea that combined with traditional heating method,new heating technique and new energy.The pattern composition,energy structure and integration were analyzed.Suitable condition for seven kinds of heating system mode were proposed.Through the study on seven kinds of integrated heating system,it can not only solves the rural energy problems,but also reduces the straw,firewood and the use of commercial energy.It plays a role on suiting one's measures to local conditions,energy saving,saving expenditure,environment protect and so on.Moreover,it increases renewable and clean energy utilization rate and reduces the economic burden of farmers.This study provides the theoretical analysis basis for the rural residential low power consumption integrated heating system.Using fluent simulation software to simulate and analyze the designed seven kinds of heating mode,which can better reflect heating effect of new integrated heating system.The simulation results show that the seven kinds of heating system can meet the needs of people on indoor heating,people mainly range in winter indoor activities,meet the requirements of comfort.The heating effect is the best:solar energy heating system +capillary network + phase change heating system.Through the energy saving,efficiency,environmental protection,contrast analysis and simulation study of the new design of the seven most conventional fire resistance heating mode and rural application-TuNuanQi heating.It Comes to the conclusions that Energy saving effect of solar + capillary net heating system+phase change heating system is best,the section coal is about 1073 kg,Phase change energy storage heating system is the next,hot style heater + solar heating system+ capillary network is the least,section coal is about 528 kg.Assume that Use fixed number of year is 10,economy of Solar + capillary net heating system+ phase change heating system is the best,it can Save money about 63000 yuan;phase change energy storage heating system is the next;hot style heater +solar heating system + capillary network is the least,it can Save money about 28000 yuan.Seven newly designed integrated heating systems have evident energy saving effect and the indoor thermal environment has been improved.In order to improve rural heating system energy-saving scientific and systematic,this paper aimed at rural kang heating systems,firewall masonry methods and equipment selection process to proposed the corresponding technical requirements,which can better play the role in energy co nservation of rural residential building heating system.
