Problems solved by technology

[0013] a. Limited by the water source, the unit is a forced air-cooled air conditioner with a large volume and a weight of 5 to 8 tons. The selected chassis has a large carrying capacity, which increases the cost of the unit
[0014] b. Due to the large size of the unit, it occupies a certain area of ​​the aircraft stop and will cause unsafe factors to the aircraft and other supply vehicles
[0015] c. If the unit has its own generator set, it will cause a lot of noise on the apron, and the exhaust gas emitted by the generator set will cause environmental pollution at the airport, which will affect the normal take-off and landing of the aircraft in severe cases
[0016] d. If the unit does not have its own generator set, it needs an external power supply. According to the parking position of the aircraft, the cables required are long, and the cables are extremely inconvenient to retract and unwind, and cause certain obstacles and unsafe factors to passing vehicles.
[0017] e. The energy consumption of the unit is high, the air supply hose is long, the temperature rises 5-7°C, the noise is loud, and the condensed water discharge is inconvenient, causing environmental pollution on the apron

Embodiment Construction

[0049] The invention consists of two parts: 1. Air-conditioning unit (ADM) for energy-saving and environmental protection on the ground of aircraft with dual cold sources; 2. Underground passage system (GSS).

[0050] 1. The dual-cooling source aircraft ground energy-saving and environmental protection air-conditioning system (ADW) uses the cold water (a certain concentration of ethylene glycol-water solution or NaCl-water solution) of the central air conditioner in the airport terminal to adjust the air through the water-through heat exchanger and evaporator. Temperature, the air conditioning unit that provides comfortable, fresh air to the aircraft.

[0051]The unit is composed of a multi-stage water-cooled air treatment system with cold water provided by the central air conditioner as the heat exchange medium and a vapor compression air treatment system with refrigerant as the heat exchange medium. The two systems include the following components:

[0052] 1-air supply hos...

Abstract

The invention relates to a dual cold sources airplane ground energy-conserving and environment-protective air-conditioning system, which solves the problems of high energy consumption, parking apron occupation and high operating cost in prior airplane ground air-conditioning unit. The system consists of a first air processing system and a second air processing system in compression refrigeration type; wherein, the first air processing system takes water supplied by a central air conditioner as heat transferring medium; the second air processing system in compression refrigeration type takes refrigerant as heat transferring medium. In the first processing system, a water-through heat exchanger (7) is injected with water from the central air conditioner of airport lounges by a pump (8) to carry out heat exchange with air from airport lounges or gallery bridge channel; the cooled air is transmitted into an engine room parked in the airport driven by a centrifugal fan (6) through a evaporator, an air outlet hood (1) and a underground passage; water after heat exchange by the water-through heat exchanger (7) is directly or through a double pipes heat exchanger to discharge into a water-storing system of the central air conditioner in airport lounges. The first processing system and the second processing system are located in the airport lounges. An underground passage system comprises an air supply duct with an insulating layer (22) buried under landing field outdoor, one end of the air supply duct is connected with the air supply tube (1), and the other end thereof is connected with a tube (23).

Description

Technical field: [0001] The present invention relates to aviation ground equipment, in particular to air conditioning systems used by aircraft on the ground. Background technique: [0002] Now major airports use bridge-mounted, fixed or mobile air-conditioning systems for the air treatment inside the ground aircraft. The bridge-mounted air-conditioning system is hoisted under the boarding bridge, and the unit and air supply hose move with the boarding bridge. The fixed air-conditioning system is installed next to the fixed column of the boarding bridge, and the mobile air-conditioning system can be moved to the parking position of the aircraft. [0003] 1. Defects in the bridge-mounted air-conditioning system and its installation method: [0004] a. Because the unit is hung under the boarding bridge, limited by the water source, it cannot be made into a water-cooled unit, but can only be a forced air-cooled air conditioner. The weight of the unit with different cooling cap...
