| In order to solve problems of huge usage of natural gas due to coal-to-gas project in Urumqi,we should research energy consumed for heating of office buildings and calculate heat loss index of office buildings,research factors of energy consumed for heating and control energy consumed for heating of office buildings,which tries to lower energy consumed for heating from terminal of heat supply and reduce heat supply of boilers for gas of heat supply so as to reduce consumption of natural gas.In this text,the research could be mainly divided into two areas for energy consumed for heating of office building in Urumqi: firstly the research of heat loss index of office buildings aims to ensure energy consumption baseline which is used for standardize and control energy consumption of newly-built buildings;secondly the research of factors with influences on energy consumed for heating of office buildings could firstly analyze single factor among influence factors to ensure the influences for heat loss index of office building due to changes of single factor,which in return obtains quantitative relation between single factor and heat loss index of office buildings so as to show curve fitting and linear regression equation of single factor and heat loss index of buildings;secondly analyzing the influences on heat loss index of buildings as a result of many factors will ensure the sequence and significance level of influences for energy consumed for heating of buildings based on influences factors so as to decide major factors of energy-saving reconstruction of buildings,which aims to make clear of sequence of energy-saving tasks under principles of invigorating key areas and relaxing control over small ones.Heat loss index of building is confirmed by adopting theoretical calculation,software simulation and actual testing in experiment,while theoretical calculation adopts static calculation of energy consumption-efficient heat transfer coefficient measurement,software simulation applies dynamic calculation of energy consumption,which adopts DeST,namely simulation software of energy consumption,to carry out modeling for dynamic simulation of energy consumption for buildings,experimental measurement investigates,collects and arranges data of energy consumption for 24 office buildings,in the final analysis,three research approaches will bear proof to each other so as to obtain relatively correct heat-loss index value of office buildings and distribute scope for this index.All we need to do should be as the following:First is to determine the influences of single factor on energy consumed for heating of public buildings.Then we make use of DeST-c software to carry out regular simulation for every influence factor of energy consumed for heating and turn data into chart so as to show its rules and work out fitting formula which explains influences of every factor on heat-loss index of buildings.Second is to determine significance level for influence of many factors on energy consumed for heating.We could be able to combine orthogonal experiment and software simulation to conduct range analysis and analysis of variance for experimental results,which in return conducts sensitivity analysis between influence factors of energy consumption and energy consumed for heating about buildings so as to determine sequence and significance level of influence factors. |
