Integration Study On Solar Hot Air Heating System With Shihezi Buildings

Solar thermal technology is an important way to use solar energy and its rational usecould effectively solve the prolem of energy shortage.Solar hot air heating system with itssuperior features,could make up shortcomings of solar hot water system, suchasinvestment,freezing,leakage,slow startup,etc,and easy implementation integration in thebuilding and should be widely used. For this,this paper studied integeration of solar hot airheating sysem with building of Shihezi,mainly to optimize structural and import parameters ofsystem. Which can improve indoor thermal comfort andreduce energy consumption inbuildings and the pollution of environment．In this paper,several kinds of solar air heating systems,Trombe wall,OM solar energysystem and SolarWall system are analyzed and corresponding design principles aresummarized; Analysis of the climate characteristics of Shihezi region and the currentutilization of solar energy and requirements. In order to this paper design two new solar airheating system, which can respectively integration of the countryside and city feature buildingof Shihezi.Firstly, study of rural and city area features residential building of Shihezi. If it want touse of solar heating chould the planning and design requirements, building monomer designrequirements, design requirements of maintenance structure as well as the main heatingrequirements;Secondly, the selection and design of detailed two kinds of solar air heating system thematerial, absorbing coating, system control and operation mode, and combined with thecharacteristics residential buildings and special climate of Shihezi to comprehensive design ofhot air heating system suitable this;Thirdly, formulas and calculation methods are summarized in the system of solar fraction,building energy-saving rate,etc. solar hot air heating system is more complex in Shihezi ruralareas, so this paper adopts Li Yuanzhe editor of " Thermal Design Handbook For PassiveSolar Houses " in formula in calculation, solar air heating system using RETScreen softwaresimulation analysis in Shihezi city areas;Fourthly, taking a rural residential and a urban characteristics of a multi-storey buildingin Shihezi as an example, the integrated design of solar air heating system and architecture,and the rural residential149regiment4company demonstration room that the fieldexperiment was carried out that the influence of hot air heating system for residential winterheating and summer ventilation and heat insulation.Overall, if designed reasonally, solar fraction of hot air heating system was very high,and in view of its economic, it should be popularized in Shihezi buildings, which couldaccelerate the work of energy saving and emission reduction in Shihezi.
