The invention relates to an electric aircraft double-evaporator air conditioning system and a control method thereof in the technical field of aircraft temperature control, and the air conditioning system mainly comprises a compressor, a condenser, a condenser fan matched with the condenser, a liquid storage tank, double evaporators, double expansion valves, a plurality of temperature sensors and a plurality of pressure sensors, according to the invention, the state of the refrigerant at the outlet of the evaporator is monitored, and the physical property state of the refrigerant at the outlet of the evaporator is confirmed in combination with the pressure enthalpy characteristic diagram of the refrigerant. And comparing the target set state point, and adjusting the rotating speed of a corresponding evaporator fan or the rotating speed of an expansion valve or a compressor to realize the optimal state of the refrigerant at the outlet of the evaporator, so that the refrigerating effect of the whole system is optimal and the energy consumption is lowest.

    本发明涉及飞行器温度控制技术领域的一种电动飞行器双蒸发器空调系统及其控制方法,空调系统包括系统主要由压缩机、冷凝器及配套的冷凝器风扇、储液罐、双蒸发器、双膨胀阀、若干个温度传感器和压力传感器,以及连接这些设备的管路和附件等组成,本发明通过对蒸发器出口的制冷剂状态的监测,结合制冷剂的压焓特性图,确认蒸发器出口的制冷剂的物性状态。对比目标设定状态点,通过调节对应的蒸发器风扇转速或者膨胀阀或者压缩机转速,来实现蒸发器出口的制冷剂状态处于最佳状态,从而使得整个系统的制冷效果最佳且能耗最低。
