An installation process for air-conditioning outlet duct of rail vehicle

Abstract

The invention provides an installation process for an air conditioning outtake of a railway vehicle. The process comprises the following steps that: an installation seat, which horizontally extends into a passenger room, is welded on an upright column of a sidewall; a first limiting component and a second limiting component are fixed on the two sides of the outtake to form an outtake module; the outtake module is integrally mounted on the vehicle; the outtake module is placed on the installation seat and fixed by bolts; an outtake branch is in compression joint with an air inlet of the outtake, and the joint part is sealed by a sealing rubber strip; the outer end of an internally installed roof of the vehicle is inserted into a slot of the second limiting component; and the upper ends of internally installed side wallboards are overlapped on a bending part of the second limiting component. According to the process provided by the invention, the side roof, the side wallboards and the outtake are organically combined and reasonably connected, so that the space in the passenger room can be maximized, and the ride comfort of passengers is improved. The installation process provided by the invention has the characteristics that the installation time on the vehicle is short, the installation quality is high, and the maintenance is facilitated.

Description

technical field [0001] The invention relates to an installation process for an air outlet duct of an air conditioner of a rail vehicle, and belongs to the technical field of rail vehicles. Background technique [0002] With the vigorous development of rail transit in recent years, the user's requirements for ride comfort have gradually increased, which has brought a lot of challenges to the design of passenger cars. [0003] Existing passenger car air conditioners mostly use the air supply mode on the roof side, and the wind is sent from the main air duct to the secondary air duct, and then enters the interior of the passenger compartment. The secondary air duct of the air conditioner is hoisted under the roof frame, occupying a large space in the car, affecting the appearance of the car and ride comfort, and the air supply outlet is close to the middle of the vehicle, so the uniformity of the air supply air flow is not good, and there are dead air supply angles. Moreover, ...

AI Technical Summary

Problems solved by technology

The secondary air duct of the air conditioner is hoisted under the roof frame, occupying a large space inside the car, which affects the appearance of the car and ride comfort, and the air supply outlet is close to the middle of the vehicle, so the uniformity of the air supply air flow is not good, and there are dead air supply angles

Moreover, the existing air duct needs to be assembled and installed on the vehicle, the installation period is long, time-consuming and laborious, and the installation technical requirements of the team workers are high
