摘  要:良好的自然通风设计可有效提升室内空气品质并改善室内热环境,但难以满足全年在室人群的热舒适需求。“自然通风+空调”联动模式不仅能够保障建筑全年室内舒适和健康,且是实现近零能耗建筑目标的重要被动技术途径。然而,上述联动模式在实际工程中的应用案例极少,导致设计与运行经验极度匮乏。采用CFD软件Fluent对广州地铁设计研究院地铁设计大厦进行了过渡季通风策略的综合优化设计,提出了基于热舒适参数的“空调+自然通风”自适应联动策略,可使地铁设计大厦全年室内自然通风热舒适时长范畴达到1097~1351 h,辅助其实现了近零能耗建筑目标。研究结果可为建筑自然通风与空调联动系统的成熟应用提供设计与运行方面的参考经验。Good natural ventilation design can effectively improve indoor air quality and thermal environment,but it is difficult to meet the thermal comfort needs of people indoor all year.The“natural ventilation+air conditioning”linkage mode can not only ensure the indoor comfort and health of the building throughout the year,but also is an important passive technical way to achieve the goal of near-zero energy buildings.However,there are few application cases of the above linkage mode in actual engineering,resulting in an extreme lack of design and operation experience.The comprehensive optimization design of the transition season ventilation strategy was carried out for the Metro Headquarters of Guangzhou Metro Design and Research Institute with CFD software-Fluent,and an adaptive linkage strategy of“air conditioning+natural ventilation”based on thermal comfort parameters was proposed,which could make the annual indoor thermal comfort time of the Metro Headquarters reach 1097~1351 hours in virtue of natural ventilation,helping it achieve the goal of near-zero energy building.This paper can provide reference experience in the design and operation of the mature application of building natural ventilation and air conditioning linkage system.
