商铺在不同热工分区的夏季空调负荷特点研究

Study on the Characteristics of Air Conditioning Load of Shops in Different Thermal Zones in Summer

文章以商场建筑中某含有两面外墙、无采光的铺位为研究对象,从计算分析的角度论证围护结构对建筑室内热环境的稳定作用,结果表明:当商铺热工设计参数采用《建筑节能与可再生能源利用通用规范》(GB55015—2021)规定的限值时,不同热工分区商场建筑的夏季空调室内冷负荷仅相差约10%,但夏季空调新风负荷存在较大差异,因此在空气处理设备选择时应将室内负荷与新风负荷结合考虑,以寻求最大的节能效果和经济效益。

In this paper,a shop with two outer walls and no sunlight is taken as the research object.From the point of view of calculation and analysis,the stability effect of the building envelope on the indoor thermal environment is demonstrated.The results show that when the shop thermal design parameters adopt the limit values specified in the General Code for Energy Efficiency and Renewable Energy Application in Buildings(GB 55015—2021),there is only about 10%difference in the indoor cooling load of air-conditioning in summer in different thermal zones,but there is a big difference in the fresh air load of air-conditioning in summer.Therefore,indoor load and fresh air load should both be considered in the selection of air treatment equipment to seek the maximum energy-saving effect and economic benefits.
