天津美术馆空调系统设计探讨
Air conditioning system design of Tianjin Museum
摘要：
根据建筑内部空间特点，以保证工作区空调效果的空调系统节能为出发点，采用CFD模拟分析软件，对比研究了不同空调风系统与气流组织形式对体积较大但空间冷热负荷指标较低的高大展厅以及步进式序厅共享空间的适应性；通过对空调区域正压平衡风量的分析计算，指出了GB 50189—2005第5.3.14条关于排风热回收规定对于艺术类展览建筑的局限性。
Abstract：
Under the condition that the air conditioning effect in the working area is guaranteed with considering the energy saving of the air conditioning system and the feature of the interior space of the building, discusses the adaptability to the tall hall with larger space and less heat load and shares space with step-sequence halls under different air systems and different air flow patterns by CFD. After analysing and calculating positive pressure balance air volume in the air conditioned area, points out the limitation of item 5.3.14 in GB 50189—2005 when concerning heat recovery for exhaust air in art gallery buildings.
