Air-conditioner air duct system used for intercity motor train unit

Abstract

The invention relates to an air conditioner air duct system used for an intercity motor train unit. The air conditioner air duct system used for the intercity motor train unit comprises an air conditioning unit and a waste exhaust unit, wherein the air conditioner unit is arranged at the top of a vehicle, and the waste exhaust unit is arranged at the bottom of the vehicle. An air outlet and an air inlet which are formed in the inner side of an air conditioning unit chamber are respectively communicated with an air supply outlet and an air return inlet located in the vehicle through an air supply duct and an air return duct which are arranged at the top of the vehicle. The air supply outlet located in the vehicle at least comprises an air supply outlet in a passenger chamber carriage, an air supply outlet in a bathroom and an air supply outlet in a driver cab. The air return inlet located in the vehicle at least comprises an air return inlet in the passenger chamber carriage and an air return inlet in the driver cab. The waste exhaust unit is communicated with a waste exhaust air outlet located in the vehicle through a waste exhaust air duct. The waste exhaust air outlet in the vehicle at least comprises a waste exhaust air outlet in the passenger chamber carriage and a waste exhaust air outlet in the bathroom. The air conditioner air duct system for the intercity motor train unit facilitates the reduction of the weight of the air ducts, satisfies higher requirements for vehicle light weight and is beneficial for the equality of air flow distribution in the vehicle. Meanwhile, due to the fact that waste gas is exhausted from the waste exhaust unit at the bottom of the vehicle, the air-tightness requirements of the vehicle are further met.

Description

technical field [0001] The invention relates to an air-conditioning duct system, in particular to an air-conditioning duct system used on an intercity EMU, and belongs to the technical field of rail vehicle air-conditioning manufacturing. Background technique [0002] The intercity EMU is a newly developed model to meet the requirements of the rapid regional economic development and the rise of urban agglomerations in my country. It has the characteristics of large passenger capacity, fast start and stop, etc., and is different from previous models in terms of speed and design structure. Therefore, only by designing and developing a suitable air-conditioning system for the actual situation of intercity trains can the air parameters and air quality in passenger cars meet the requirements and provide passengers with a comfortable travel environment. At present, the domestic train air supply duct system is generally installed at the top of the car. The air supply system adopts t...

AI Technical Summary

Problems solved by technology

This kind of air-conditioning duct system has poor uniformity of wind speed and temperature distribution in the car

Secondly, the high-speed driving of 200km / h intercity vehicles also has high airtightness, and the existing air-conditioning duct system cannot meet the higher requirements for airtightness
