摘　　要：为对邮轮中庭分层空调系统进行实际设计与应用,基于计算流体力学(computational fluid dynamics)方法,采用离散坐标(discrete coordinate,DO)辐射模型和Realizable k-ε湍流方程,对某一典型邮轮的中庭计算分层空调典型日冷负荷和气流组织分布的数值模拟研究。从舒适性、送风有效性和均匀性等角度对比分析在最大冷负荷下的全空气分层空调中庭应用的结构参数、送风参数。研究表明,分层空调的冷负荷相较于未分层的建筑低了7%左右;送风角度适宜为15°,侧送风风量比例系数在0.7左右较为合理。本文的研究综合分层空调系统负荷和中庭内部热环境两方面,以期为今后分层空调系统在邮轮中庭的实际应用提供设计参考。To provide scientific basis and reference for the practical design and application of the tiered air conditioning system in the cruise atrium.The present study employs computational fluid dynamics,Discrete coordinate(DO)radiation model and Realizable turbulence equation to simulate the typical daily cooling load and airflow distribution in the atrium of a standard cruise ship using stratified air conditioning.From the perspectives of comfort,air supply effectiveness,and uniformity,a comparative analysis is conducted on the structural parameters and air supply parameters of all stratified air conditioning systems under maximum cooling load.The findings reveal that stratified air conditioning reduces the cooling load by approximately 7%compared to unstratified buildings.Moreover,an optimal air supply angle of 15°is identified,while a proportional coefficient for side air supply around 0.7 proves more reasonable.This research aims to provide design references for future practical applications of stratified air conditioning systems in cruise ship atria by investigating their cooling loads and internal thermal environments.
