深圳地铁梨园高架车站通风空调系统优化设计

The Optimization Design of Ventilation and Air Conditioning System in Liyuan Elevated Station of Shenzhen Metro

为减少深圳地铁四期工程梨园高架车站土建与环控投资,同时保证空调系统能够满足高架车站各房间使用需求,文章根据现有高架站在实际运营中的使用情况分析了高架车站在暖通空调设计中存在的问题。并针对存在的问题,从车站负荷计算、排烟系统和通风空调系统形式三方面,对深圳地铁梨园高架车站进行优化设计,同时在设计中使用BIM技术构建了梨园站通风空调系统三维模型,根据模型调整管道路由降低阻力损失以实现高架车站通风空调系统节能目标。

In order to reduce the investment in civil engineering and environmental control of Liyuan Elevated Station of Shenzhen Metro Phase IV Project,and ensure that the air conditioning system can meet the needs of each room of the elevated station,the problems existing in the HVAC design of the elevated station are analyzed according to the use of the existing elevated station in actual operation.In view of the existing problems,the optimization design of Liyuan Elevated Station of Shenzhen metro is carried out from three aspects:station load calculation,smoke exhaust system and ventilation and air conditioning system.At the same time,BIM technology is used to construct the 3D model of ventilation and air conditioning system of Liyuan Station.According to the model,the pipe road is adjusted to reduce the resistance loss to achieve the energy-saving goal of ventilation and air conditioning system in elevated station.
