Abstract

The invention discloses a variable frequency high-precision aircraft ground air conditioning unit and a control method of the aircraft ground air conditioning unit. The aircraft ground air conditioning unit comprises a frame structure, an air conditioning air supply system, a first refrigerating system, a second refrigerating system, a third variable frequency refrigerating system, a fourth variable frequency refrigerating system, a heating system and an automatic control system, wherein the frame structure comprises an air conditioning box, and a first axial flow fan, a second axial flow fan and a third axial flow fan which are arranged on the air conditioning box; all the systems are arranged in the frame structure; and the first axial flow fan, the second axial flow fan, the third axial flow fan, the air conditioning air supply system, all the refrigerating systems and the heating system are respectively connected with the automatic control system. The variable frequency high-precision aircraft ground air conditioning unit is reasonable in design, high in efficiency, energy-saving, high in adjustment accuracy, high in intelligence degree, compact in structure, small in volume, light in weight, high in safety performance and stable and reliable in running, saves the energy, reduces the environmental pollution, and is high in outlet air temperature adjustment accuracy.

Description

technical field [0001] The invention relates to the field of aircraft ground air-conditioning equipment, in particular to a frequency conversion high-precision aircraft ground air-conditioning unit and a control method thereof. Background technique [0002] At present, in the general aircraft ground air conditioning unit, the fresh air is directly evaporative cooling or electric heater heating treatment of multiple (stage) refrigeration systems of the unit, and the cold air or hot air is sent through the aircraft air conditioner through the insulated delivery hose and quick connector. The air outlet is sent into the aircraft cabin and cockpit to provide processed cooling air with a certain flow rate, temperature and pressure for the aircraft parked at the airport. [0003] However, due to the fixed-frequency refrigeration system and non-high-precision control method used in this type of aircraft ground air-conditioning unit, the energy consumption is large during part-load o...
