摘要
针对智能轨道交通空调系统智能控制需求,采用变频空调机组技术,集制冷、制热、新风、废排、空气净化、除湿、被动式压力控制保护为一体,设计研发了轨道交通空调系统智能控制技术并应用;结果表明,通过调节压缩机运行频率可实现车内温度的精确控制,使实际温度逐步接近目标温度,温度波动范围控制在±1 K以内;变频技术可避免压缩机频繁启停,降低空调能耗10%以上;空气净化装置可实现甲醛去除率约为86%;细菌去除率约为92%;PM2.5过滤效率可由40%提高到70%;同时智能运维系统对空调系统进行故障诊断和预测,降低公司的维保人力成本;该研究可为轨道交通车辆空调系统的智能化研究与应用提供技术参考。
In response to the intelligent control requirements of the intelligent rail transit air conditioning system,the inverter of air conditioning unit technology is adopted to integrate the function of refrigeration,heating,freshing air,exhausting,air purification,disinfection and sterilization,dehumidification,and passive pressure control protection to design and develop the rail transit air conditioning system.The results show that the precise control of the temperature in the vehicle is achieved by adjusting the operating frequency of the compressor,so that the actual temperature gradually approaches the target temperature,and the temperature fluctuation range is controlled within±1 K,avoiding frequent start and stop of the compressor,and reducing the energy consumption of the air conditioner by more than 10%;The air purification device can achieve a formaldehyde removal rate of about 86%;a bacteria removal rate of about 92%;PM2.5 filtration efficiency can be increased from 40% to 70%.The intelligent operation and maintenance system diagnoses and predicts the air conditioning system,thereby improving the efficiency of the entire after-sales service team and reducing the company's maintenance labor costs.This research can provide a technical reference for the intelligent research and application of air-conditioning systems for rail transit vehicles.
