The invention discloses a transcritical CO2 air conditioner heat pump system control method for a plateau rail vehicle, and the control method aims at the plateau rail vehicle and comprises the steps that the indoor air volume is adjusted to be matched with a cold load and a heat load which change along with the altitude, and the optimal air volume is found; the fresh air ratio is adjusted to ensure that the oxygen concentration and the carbon dioxide concentration of the compartment are within the safe range, and the minimum fresh air ratio is found; and calculating the optimal exhaust pressure of the carbon dioxide cycle in real time. The system uses refrigerant carbon dioxide and is energy-saving and environment-friendly; the control method aims at meeting the normal functions of the system, reducing energy waste and effectively improving the energy efficiency of the system.

    本发明公开了一种高原轨道车辆的跨临界CO2空调热泵系统控制方法,针对高原轨道车辆,本发明控制方法包括调节室内风量以匹配随着海拔变化的冷负荷与热负荷,并寻找最优风量;调节新风比以确保车厢的氧浓度与二氧化碳浓度处于安全范围,并寻找最小新风比;实时计算二氧化碳循环最优排气压力。系统使用制冷剂二氧化碳,节能环保;控制方法旨在满足系统正常功能的同时,减少能源浪费、有效提升系统能效。
