Embodiment 1

[0044] In this embodiment, the main components are realized by products in the prior art. The difference is that the ground air-conditioning unit has an overall frame structure, and the interior is divided into upper and lower layers. The upper frame is placed on the ground for condensation and heat dissipation, including condensation 12, condensing fan, display panel and some electrical boxes; Wherein the compressor 8 and the electric control box 9 are provided with a partition 7, and between the primary and secondary evaporators and the air blower, and between the air blower and the third and fourth evaporators, a partition 7 is arranged to divide the chambers to prevent cross-winding.

[0045] Because condensation heat dissipation requires an outdoor ventilation environment, the upper part contains multi-stage condensers, condensing fans, electric control boxes for the display operation part, air inlet 3 and part of the air duct, which is the air inlet duct 4 (the air inlet ...

Abstract

The invention provides an airplane ground air conditioning unit, relates to the technical field of air conditioners, and solves the technical problems that an air conditioning unit is large in size and occupies ground space. The airplane ground air conditioning unit comprises a condensation unit arranged on the ground and an evaporation unit arranged under the ground, the evaporation unit communicates with an airplane inner cabin to continuously provide needed fresh air, and the condensation unit is connected with the evaporation unit through a refrigerant pipeline. The whole unit is divided into an upper-layer structure and a lower-layer structure, the evaporation unit and the condensation unit are separated, the upper-layer condensation unit is placed on the ground and used for condensation and heat dissipation, the lower-layer condensation unit is embedded into the underground space and used for supplying air to an inner cavity of an airplane after cooling, the length size of an evaporator is only limited in terms of the width direction, the size of the unit in the width direction is reduced, and the occupied area is greatly reduced; and the evaporation unit on the lower layer is embedded into the underground space, the increased height space can be counteracted, and the ground height space cannot be occupied.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air-cooled aircraft ground air-conditioning unit of an upper and lower layered embedded installation. Background technique [0002] The aircraft ground air conditioning unit is mainly used to provide ventilation air with a certain flow, pressure and temperature for the aircraft when the aircraft is parked on the ground. The unit adopts direct evaporative refrigeration cycle technology, multi-stage heat exchange, through the evaporation of refrigerant in the evaporator coil, the air is cooled and cooled, and the low-temperature air is sent into the aircraft cabin by the blower. [0003] Since the aircraft requires the input of outdoor fresh air, it needs a large enthalpy difference to supply air, and generally needs 3 or more heat exchanges. All heat exchangers, fans, compressors, etc. are placed in the space on the first floor, and the width direction is relatively la...
