摘　　要：本文基于对商场通高中庭空间在冬季不同运行工况下,通过数值模拟分析软件定量分析及现场实地调研核查,明确了影响中庭垂直温差的主要影响因素为高/低区出入口冷风侵入管控,建筑围护结构气密性,暖通空调系统控制措施及厨房排补风系统联动。通过分析各主要出入口,幕墙及管井等无组织渗漏风对中庭垂直温差的影响,重新规划各楼层空调送风风量及温度,提出相应的空调运行策略优化中庭垂直温差,探讨降低空调能耗的可能性。This study indicates the main factors for influencing the vertical temperature difference of atrium through numerical simulation and field study,for which are management of building entrances,airtight of building envelope,control strategies of HVAC system and interaction of kitchen exhaust and intake vents.The impact of inorganized cold air intrusion through building entrances,building envelope and pipe wells are studied for optimization of airflow volume and temperature of supply vents.Suggestions for HVAC operation strategies are provided to improve the vertical temperature difference of atrium for further possibility of reducing building energy consumption.
