With the rapid development of economic activities and social production in our country,a lot of energy consumption is used,this not only cause the energy situation is increasingly serious,but also a lot of waste gas,smoke into the atmosphere,SO2,the suspension,particulate matter,NOX,greenhouse gases will not only harm the atmospheric environment,even threaten people’s health,the quality of the ecological environment.The air pollution gas mainly comes from the harmful gas released by the large combustion of coal in the industrial and household heating process.Although the atmosphere has a certain self-purification ability through diffusion,sedimentation,oxidation and other effects,this self-purification ability is limited in a certain time period.With the increase of the concentration of pollutants,it will also cause haze weather in serious cases,which will have a serious negative impact on human health and ecological environment.The emission problem of air pollution needs to be solved.In recent years,China has introduced some relevant policies to control air pollution,and proposed to use clean energy instead of traditional energy for heating methods.Common clean energy sources include wind energy,solar energy,tidal energy,biomass energy,etc.,through the use of clean energy to achieve clean heating,effectively reduce air pollution emissions.Firstly,this paper establishes the residential building model with the energy saving rate of 65%in cold areas through the De ST energy consumption simulation software,calculates the heating load for the residential buildings in Harbin area,analyzes the load simulation results,and obtains the relevant parameters such as the cumulative heat consumption and heat consumption index of the building.Then with gas boiler,electromagnetic boiler as auxiliary heat source,and with air source heat pump,solar heating,soil source heat pump+solar season heat storage three kinds of clean heat source into a combination of the heating system as the research object,according to the De ST software load simulation results to establish the energy consumption of the heating system model,carbon emissions model,for different heating system of standard coal consumption,power consumption and CO2emissions calculation.The initial investment and operation cost of different heating systems are analyzed and calculated,and the annual value of the cost of different clean heating systems is obtained.Through the comparative analysis of the energy saving,economy and environmental benefits of different heating systems,the solar energy heat collection+gas boiler heating system is determined as the comprehensive optimal scheme.In this study,based on the establishment of energy consumption model,carbon emission model and relevant numerical analysis and calculation,the relevant comparative study is quantified,which is convenient to facilitate the more intuitive analysis and comparison of different heating schemes in the research process,and has certain guiding significance and reference basis for the selection of clean heating system in cold areas. |
