摘　　要：结合2010年冬季双流机场T1航站楼空调参数的测试数据,对利用经验系数法计算分层空调负荷的经验系数取值进行研究,研究中CFD技术所需的边界条件按实测值或通过间接计算确定,尽可能接近实际,保证计算结果的可靠性。研究表明,T1航站楼冬季室内仍处于制冷工况,类似于T1航站楼指廊部位的分层空调,经验系数取0.67较为合适,该经验系数适用于冷负荷的计算。同时得出类似高大空间CFD计算的边界条件设置方法。Combined with air-conditioning parameters of Shuangliu Airport terminal 1 （T1） tested in the 2010 winter, the value of empirical coefficient for stratified air-condi- tioning load calculating by empirical coefficient method is studied. In order to ensure the reliability of the results, the boundary conditions needed by CFD technology are determined according to measurement or indirect calculation which are close to reality as much as possible. The study results show that T1 is still in cooling conditions in winter and the value of empirical coefficient is about 0.67 for load calculating of stratified air-conditioning in large space like T1. That value is applied to cooling load calculation. The setting method of boundary conditions for the similar large space is obtained.
