The invention discloses a control method of a split type railway vehicle air conditioning unit, and belongs to the technical field of railway vehicle air conditioners. The control method comprises the following steps: A, setting a set temperature in a carriage, and controlling the air conditioning unit to operate in a ventilation mode or a refrigeration mode by a control system according to an outdoor temperature and the temperature in the carriage; and B, when the air conditioning unit operates in the refrigeration mode, monitoring the temperature TIGBT of an IGBT in a frequency conversion unit in real time, and adjusting the operating frequency range of the frequency conversion unit according to the TIGBT. The method has the advantages that 1, the frequency conversion unit can work at a better working temperature, and the comfort degree of passengers in the carraige is guaranteed; and 2, a guide plate is additionally arranged for the frequency conversion unit, so that airflow passing through radiating fins of a frequency converter and radiating fins of a power factor correction device is more uniform and rapider, and the temperature control of the IGBT is facilitated.

    本发明公开了一种分体式轨道车辆空调机组的控制方法,属于轨道车辆空调技术领域,包括以下步骤:步骤A、设置车厢内的设定温度,控制系统根据室外温度和车厢内温度控制空调机组运行在通风模式或制冷模式;步骤B、当空调机组运行在制冷模式时,实时监测变频单元内IGBT的温度TIGBT并根据TIGBT调整变频单元的运行频率范围。本发明的有益效果是:1、本发明的方法可以使得变频单元工作在更好的工作温度下,保证车厢内乘客的舒适度;2、为变频单元增加了导流板使经过变频器散热翅片和功率因数校正装置散热翅片的气流更均匀、流速更大,更利于IGBT的温度控制。
