摘要:严寒地区高大空间的空调与供暖是暖通设计的难点,应根据项目建筑、结构的约束条件,制定合理的空调与供暖方案。以中韩城市馆项目为例,分析了高大空间的双温度梯度特点,提出了长边双层分层空调系统,在周边靠近围护结构处布置立式风机盘管,在中间区域布置送风岛,在大门处设置双侧对吹热风幕的组合空调与供暖方案。指出设计除了需满足高大空间运营工况时的舒适度要求外,还要注重整个建筑的防冻设计。

Abstract: Air conditioning and heating for large spaces in severe cold zone is a difficult point in HVAC design.A reasonable air conditioning and heating scheme should be made according to the architectural and structural constraints of the project. Taking the China-Korea City Pavilion project as an example, this paper analyses the characteristics of dual temperature gradients in large spaces, and proposes a combination air conditioning system, in which the double stratified air conditioning system is installed on the long side, vertical fan-coil units are arranged near the building envelope, the air supply islands are added in the middle area, and the double opposite blowing hot air curtains are installed at the gates. It is pointed out that the design should not only meet the comfort requirements of the operation conditions of large spaces, but also pay attention to the anti-freezing design of the entire building.
Keywords: severe cold zone; large space; stratified air conditioning; air supply island; anti-freezing; heating;
