Discussions on Energy-saving Technology Routes of typical cities with Different Climatic Characteristics in the Yangtze River Basin
Cities climates in the Yangtze River Basin has some characteristics in common,such as cold winter,hot summer,high relative humidity and intermittent air-conditioning using habit,which is described as air-conditioner turned off as soon as people leave the room.In this paper,climate features of several typical cities are analyzed detailed,including temperature,humidity,air-velocity,solar radiation and other else.In the light of climates characteristics,cities are classified into several types,one city is selected as a model to calculate the performance parameters by simulation software,and concrete requirements of the building envelope is given,especially thermal transfer coefficient,shading factor and so on.Shanghai energy-saving method technology route is proposed here,and the technology method of other cities need to be established by cooling/heating load ratio and climate features.By applying the design scheme supplied under the truly energy-using way,the goal of 20kWh/m2 can be achieved with slight effort of equipment performance improving.It is also found that boundary condition has a significant influence on the energy-consumption simulation result,in order to reduce the error between calculated value and actual energy using,indoor thermal disturbance should be fully considered by exploring the actual energy-using pattern.
