石家庄地铁地下停车场通风空调系统方案设计

结合石家庄地铁地下停车场通风空调系统设计,通过对停车库通风、空调、采暖、排烟4个方面的难点问题进行分析,并通过利用工程经验、借鉴规范等方法,提出全面的系统设计解决方案。研究结论:停车库内通风量、排烟量分别按照3 m层高、实际层高,6次/h换气考虑;检修平台考虑局部空调,提高作业人员舒适度;土壤有蓄热效应,按局部考虑采暖即可,不必对停车库内进行大面积采暖。

Ventilation and Air Conditioning System Design of Shijiazhuang Metro Underground Parking Lot

With regard to the design of ventilation and air conditioning system of Shijiazhuang metro underground parking,this paper proposes an overall system solution after the analysis of such key issues as air conditioning,heating,ventilation and smoke exhaustion with reference to engineering practices and specifications. The results show that ventilation and smoke exhaustion volumes are calculated on the basis of 3m assumed floor height,the actual height and 6 times of ventilation per hour; the maintenance platform is equipped partially with air-conditioning for the benefit of working staff; with the presence of ground heat accumulation,local heating is acceptable without the need for the entire parking lot.
