Rail train and air-conditioning unit complete equipment thereof

Abstract

The invention discloses air-conditioning unit complete equipment of a rail train. The air-conditioning unit complete equipment is of an integrated structure and comprises a body, a mounting seat, a grating air opening and a mixed air box; an air-conditioning unit is mounted in an air-conditioning unit mounting opening in the top of the rail train through the mounting seat in embedded and sunken modes, the mounting seat and the body are provided with a sealing component therebetween and connected through connecting pieces, and the top surface of the air-conditioning unit is lower than or flushwith the top of a train body; grating type pressure wave protection devices are arranged on the two sides of the air-conditioning unit. The structure is good in manufacturability, work efficiency canbe conveniently improved, leakage points are reduced, system reliability is guaranteed, and meanwhile the mounting strength and rigidity requirements are met and airtightness is guaranteed. When pressure fluctuation occurs outside the rail train, a controller can quickly respond to drive the sealing component to seal a vent opening, pressure in the train is prevented from being affected by pressure fluctuation outside the train, and thus comfort is improved, resistance is reduced and airtightness is enhanced. The invention further discloses the rail train comprising the air-conditioning unit.

Description

technical field [0001] The invention relates to the field of rail trains, in particular to a unitary air conditioner assembly equipment for rail trains. In addition, the present invention also relates to a rail train comprising the above-mentioned unit air conditioner assembly equipment. Background technique [0002] In order to improve ride comfort, rail vehicles are generally equipped with an air-conditioning system, whose function is to provide warm air (winter) and cold air (summer) for the compartment to meet comfort requirements. For high-speed EMUs, a pressure wave protection device should also be provided to avoid sudden pressure fluctuations inside the carriages when high-speed vehicles enter the tunnel, affecting comfort. In the existing rail trains, the air-conditioning units are mostly top-mounted or semi-embedded structures, and the top protrudes from the car body structure. When the vehicle runs at high speed, the running resistance of the train is increased, ...

AI Technical Summary

Problems solved by technology

For high-speed EMUs, a pressure wave protection device should also be provided to avoid sudden pressure fluctuations inside the compartment when the high-speed vehicle enters the tunnel, affecting comfort

In existing rail trains, air-conditioning units are mostly top-mounted or semi-embedded structures, and the top protrudes from the car body structure. When the vehicle runs at high speed, the running resistance of the train is increased, and the sealing between the car body and the air-conditioning unit is poor, which is inconvenient. Installation positioning, there is a large installation error

When the vehicle speed increases and passes through the tunnel, pressure fluctuations will occur outside the vehicle, which will enter the interior of the vehicle through the vent of the air conditioning unit, affecting comfort
