Control method of modularized airplane ground air conditioning unit

The invention discloses a control method of a modularized airplane ground air conditioning unit. According to the control method of the modularized airplane ground air conditioning unit, automatic control over the operation state of each refrigerating module is achieved by presetting an inlet fresh air temperature in a controller and comparing with an actually received fresh air temperature, accurate temperature adjustment is conducted, and meanwhile, a heater, a high pressure fan and an axial flow fan of the air conditioning unit can be controlled to operate automatically, and hot air exhausted by the axial flow fan cannot enter a fresh air inlet, and the energy consumption is reduced. 本发明公开了种模块化飞机地面空调机组的控制方法，该方法通过在控制器中预设进口新风温度，并将实际接收的新风温度进行比较，实现自动控制各个制冷模块的运行状态，进行精确调温，同时能够控制该空调机组的加热器、高压风机和轴流风机的自动运行，且轴流风机排出的热风不会进入新风进口，节省了能耗。
