In order to improve the performance of the air conditioner and reduce the faults of the air conditioner, the air conditioning system needs to be cleaned regularly, and a pressure air source and a pressure water source are matched for cleaning the air conditioning system of an airplane. In the current cleaning work of the air conditioning system of the aircraft by the aviation service, the pressure air source uses APU bleed air (APU is Auxiliary Power Unit abbreviation for auxiliary power device of the aircraft, APU bleed air high pressure can meet the high pressure requirement of cleaning the air conditioning system of the aircraft); the pressure water source is provided by a water tank of the hair washing vehicle and the water tank is pressurized by a nitrogen bottle on the hair washing vehicle (the hair washing vehicle is special equipment for cleaning an internal duct of an engine by a navigation department). The cleaning mode for the aircraft air conditioning system used at present needs to be matched and combined by using a plurality of related cleaning devices such as bottled nitrogen, shampoo vehicles, external air conditioning pipelines and the like with higher cost, and is inconvenient to use, low in efficiency and high in cost.

The water is added into the airplane water tank, so that the airplane water tank can provide drinking water for passengers, and the airplane water tank needs to be disinfected regularly in order to prevent microorganisms from breeding in the airplane water tank. In general, the work of cleaning the water tank of the airplane needs to use an airport water truck to boost pressure and add water to the water tank of the airplane (the airport water truck is equipment special for adding water to a drinking water tank on the airplane in the airport), but the use frequency of the airport water truck is high under normal conditions, and the dispatching is troublesome, so that the work of cleaning the water tank of the airplane is very inconvenient to develop and the efficiency is low.

1) In the cleaning process of the air conditioning system, nitrogen is used for pressurizing the water tank of the shampoo car, and the cost is high.

2) When the air conditioning system is cleaned, a plurality of related devices are required to be combined for use, so that the air conditioning system is inconvenient to use and low in efficiency.

3) When the aircraft water tank is cleaned, the airport waterwheel needs to be borrowed and adjusted, the time needs to be coordinated and scheduled, the time is wasted, and the work cannot be completed in time.
