The invention relates to airport ground equipment, in particular to a low-noise aircraft ground air-conditioning car, comprising a car frame and a carriage body, wherein the carriage body is internally provided with a Roots fan, a muffler, a compressor unit, evaporators, an axial flow fan, an electric heater and a condenser; and one side surface of the carriage body is provided with an access door, and the other side surface thereof is provided with an electrical heater and an operating box. The low-noise aircraft ground air-conditioning car is characterized in that the carriage body is internally provided with a bulkhead plate and is divided into a front compartment and a rear compartment; the front compartment is internally provided with the Roots fan, the muffler, the compressor unit,a front evaporator, a rear evaporator and the electrical heater; the rear compartment is provided with the axial flow fan and the condenser; the inner surface of the front compartment is provided with a skeleton which is a frame formed by mutual fixing of a bracket and cross arms and the inner side of the skeleton is provided with a muffling plate which is provided with through holes; the inner surface of the muffling plate is provided with glass wire cloth; the muffling plate respectively forms a cavity with the carriage body and the bulkhead plate by the skeleton; the cavities are filled with asbestos; the bottom of the front compartment is provided with a bottom plate; and the asbestos is filled between the bottom plate and the car frame. The low-noise aircraft ground air-conditioning car has the advantages of reasonable structure and low noise and the like.
Description
technical field [0001] The invention relates to airport ground equipment, in particular to a low-noise aircraft ground air-conditioning vehicle. Background technique [0002] As we all know, the aircraft ground air-conditioning vehicle will produce a lot of noise during the working process, which includes the frame and the box body, the box body is fixed on the frame, the box body is surrounded by ordinary cold-rolled steel plates, and the box body is a closed In the shelter, there are Roots blower, muffler, compressor unit, evaporator, axial flow fan and condenser in the cabin. The front evaporator is located on one side of the cabin. The air outlet of the rear evaporator is connected to the air inlet of the rear evaporator through the air duct, the inlet muffler and the Roots blower, and the air outlet of the rear evaporator is connected to the air pipe through the electric heater. Outside the box, there is a compressor unit on one side of the rear evaporator, a condenser...
