摘要：
合理设置通风空调系统是真空管道垃圾收集系统稳定运行的重要保障。本文以深圳某垃圾收运项目为例,基于负荷分析识别出设备与管道散热为主要热源,据此提出机械排风+多联机空调复合系统,并建立了以室外温度(25 ℃)和相对湿度(90%)作为多工况切换节点的经济运行策略。采用CFD模拟对配电室、动力风机间等关键区域通风设计进行了验证与优化,结果表明,该设计可有效控制设备运行环境温度,满足设计要求,为此类高热密度地下工业空间的通风空调设计提供了系统解决方案与实践参考。
Abstract：
Properly setting up the ventilation and air conditioning system is an important guarantee for the stable operation of vacuum pipeline garbage collection systems. Taking a garbage collection and transportation project in Shenzhen as an example, based on load analysis, the equipment and pipeline heat dissipation are identified as the main heat sources in this paper. Accordingly, a compound system of mechanical exhaust and multi-split air conditioning is proposed, and an economic operation strategy is established using outdoor temperature (25 ℃) and relative humidity (90%) as multi-condition switching nodes. CFD simulations are used to verify and optimize the ventilation design of key areas such as the distribution room and power fan room. The results show that this design can effectively control the operating environment temperature of the equipment and meet design requirements, providing a systematic solution and practical reference for the ventilation and air conditioning design of high heat-density underground industrial spaces.
