外立面辐射吸收率对公共建筑能耗的影响分析
Analysis of influence of facade radiation absorptivity on energy consumption of public buildings
摘要
Abstract
In order to analyze the relationship between the surface radiation characteristics of public buildings and building energy consumption,Chengdu and Huili were selected as typical areas to study the influence of facade radiation absorption rate on building energy consumption.The results show that with the increase of absorption coefficient,the annual heat consumption decreases and the cooling consumption increases.When the absorption coefficient is greater than 0.3,the cooling consumption increases obviously,and the increase rate is 0.3%.The roof absorption coefficient has a great influence on the refrigeration energy consumption in the meeting area,with an increase of 0.1,the refrigeration energy consumption increases by 578 kWh.The increase of external wall absorption coefficient has little influence on the fluctuation of indoor temperature rise in a single day,which is only 0.15℃.However,from the perspective of annual temperature distribution,the time period greater than 29℃increases significantly throughout the year,and the demand for cooling load increases in summer.The research content can provide reference for the optimization design of public building facade and further reduce building energy consumption.关键词
