山东通风管道在商场场景中扮演着重要角色，其设计与安装直接影响商场的空气环境、能源效率及安全保障，在多个功能维度上发挥着关键作用。

　　Shandong ventilation ducts play an important role in shopping mall scenes, and their design and installation directly affect the air environment, energy efficiency, and safety of the mall, playing a critical role in multiple functional dimensions.

　　在空气流通与环境调节方面，通风管道是商场新风系统的核心组成部分。商场作为人员密集场所，需要持续引入新鲜空气并排出室内污浊空气，通风管道通过合理的路径设计，将室外新风经过滤、处理后输送至各楼层的公共区域、店铺及卫生间等，同时将室内含有二氧化碳、异味的空气排出。这种空气循环不仅能降低室内污染物浓度，还能维持适宜的空气湿度，避免因人员密集导致的空气浑浊、闷热等问题，提升顾客的购物舒适度。此外，通风管道与空调系统配合，可将经降温或加热处理的空气均匀输送至各个区域，保证商场内温度稳定，为顾客和商户营造舒适的环境。

　　In terms of air circulation and environmental regulation, ventilation ducts are the core components of the fresh air system in shopping malls. As a densely populated place, shopping malls need to continuously introduce fresh air and exhaust indoor polluted air. The ventilation ducts are designed with reasonable paths to filter and process outdoor fresh air and deliver it to public areas, shops, and bathrooms on each floor. At the same time, indoor air containing carbon dioxide and odors is discharged. This air circulation not only reduces indoor pollutant concentration, but also maintains appropriate air humidity, avoiding problems such as air turbidity and stuffiness caused by dense personnel, and improving customer shopping comfort. In addition, the ventilation ducts, in conjunction with the air conditioning system, can evenly deliver cooled or heated air to various areas, ensuring stable temperature inside the mall and creating a comfortable environment for customers and merchants.

　　在消防排烟领域，通风管道的作用尤为关键。商场空间布局复杂，人流量大，一旦发生火灾，烟雾扩散速度快，会严重威胁人员安全。专用的消防排烟管道系统能在火灾发生时迅速启动，通过设置在天花板、走廊等位置的排烟口，将浓烟快速抽离并排出室外，减少烟雾对人员疏散和灭火救援的阻碍。同时，部分通风管道可与防火阀配合，在火灾发生时自动关闭非排烟区域的管道，防止火势和烟雾通过管道蔓延，为人员疏散争取宝贵时间。这种消防排烟功能是商场安全体系中不可或缺的一环，直接关系到人员生命安全。

　　In the field of fire and smoke exhaust, the role of ventilation ducts is particularly crucial. The layout of the shopping mall space is complex, with a large flow of people. Once a fire occurs, the smoke spreads rapidly, posing a serious threat to personnel safety. The dedicated fire smoke exhaust duct system can be quickly activated in the event of a fire. By setting smoke exhaust vents on ceilings, corridors, and other locations, thick smoke can be quickly extracted and discharged outdoors, reducing the obstruction of smoke to personnel evacuation and firefighting rescue. At the same time, some ventilation ducts can be combined with fire dampers to automatically close the ducts in non smoke exhaust areas in case of a fire, preventing the spread of fire and smoke through the ducts and buying valuable time for personnel evacuation. This fire and smoke exhaust function is an indispensable part of the safety system in shopping malls, directly related to the safety of personnel's lives.

　　在能源节约与系统优化方面，合理设计的通风管道能提升商场的能源利用效率。通过采用保温性能良好的管道材料，可减少空气在输送过程中的冷量或热量损失，降低空调系统的能耗。同时，根据商场不同区域的使用特点，通风管道可实现分区域风量调节，例如在客流较少的非高峰时段，适当降低某些区域的新风供应量，在保证基本环境质量的前提下减少能源消耗。此外，通风管道的顺畅布局能降低空气流动阻力，减少风机的运行负荷，进一步实现节能效果，符合商场运营的成本控制需求。

　　In terms of energy conservation and system optimization, well-designed ventilation ducts can improve the energy utilization efficiency of shopping malls. By using pipeline materials with good insulation performance, the cooling or heat loss of air during transportation can be reduced, and the energy consumption of the air conditioning system can be lowered. At the same time, according to the usage characteristics of different areas in the shopping mall, ventilation ducts can achieve regional air volume adjustment. For example, during non peak hours with low passenger flow, the supply of fresh air in certain areas can be appropriately reduced to reduce energy consumption while ensuring basic environmental quality. In addition, a smooth layout of ventilation ducts can reduce air flow resistance, decrease the operating load of fans, further achieve energy-saving effects, and meet the cost control requirements of mall operations.

　　在异味控制与卫生保障上，通风管道也发挥着重要作用。商场内的餐饮区、垃圾处理点等区域易产生异味，通风管道通过专门的排风设计，将这些区域的异味及时排出，避免扩散至其他区域影响整体环境。在卫生间等场所，通风管道持续的排风作用能有效降低异味浓度，保持空气清新，同时减少细菌滋生，提升商场的卫生水平，为顾客提供更舒适的购物体验。

　　Ventilation ducts also play an important role in odor control and hygiene assurance. The dining area, garbage disposal points, and other areas within the shopping mall are prone to producing odors. The ventilation ducts are designed with specialized exhaust systems to promptly remove these odors and prevent them from spreading to other areas and affecting the overall environment. In places such as bathrooms, the continuous exhaust function of ventilation ducts can effectively reduce the concentration of odors, maintain fresh air, reduce bacterial growth, improve the hygiene level of shopping malls, and provide customers with a more comfortable shopping experience.
