Embodiment 1

[0018] The air supply device at the bottom of the rail vehicle air conditioning unit provided in this embodiment has a structure such as figure 1 and figure 2 As shown, it includes a connecting air duct 1, and a transverse "C"-shaped deflector 2 is arranged at the air inlet of the connecting air duct 1, and the "C"-shaped deflector 2 guides the connecting air duct 1 into the The air outlet is divided into an air supply outlet 3 and an air return outlet 4. At the lower end of the connecting air duct 1, there is a guide return air outlet 5 communicating with the return air outlet 3. On the guide return air outlet 5, there is a The cross-section at the bottom of the unit is a rectangular air guide duct 6, which is a gradually expanding air duct made of aluminum plate and connected to the carriage through rivets. Two air outlets 7 communicating with the passenger room, the air outlet structure is as follows image 3 As shown; the "C" shape deflector is also connected with a ro...

Embodiment 2

[0021] The structure of this implementation is the same as that of Embodiment 1, the difference is that the front end of the guide air duct with a rectangular cross section is provided with an air outlet 9 communicating with the passenger compartment of the adjacent train; when the air conditioning unit in the adjacent compartment breaks down, it can The temperature of the compartment is adjusted by providing air-conditioned air to the adjacent compartment through the guide air duct.

Abstract

The invention discloses a bottom air supply device of an air conditioning unit for a railway vehicle, which belongs to the technical field of air-conditioning air supply systems for vehicles. The bottom air supply device comprises a connecting air duct. A transverse C-shaped deflector is arranged at an air inlet of the connecting air duct, and divides the air inlet of the connecting air duct intoan air supply outlet and a return air inlet. A diversion return air inlet communicated with the return air inlet is reserved at the lower end of the connecting air duct. A diversion air duct leading to the bottom of the air conditioning unit is connected to the diversion return air inlet. An air outlet communicated with a passenger room is formed at the bottom end of the diversion air duct. The bottom air supply device of the air conditioning unit for the railway vehicle solves the problem of a dead zone below the conventional air conditioning unit, meets the requirements of passengers on a temperature field and a wind velocity field in the passenger room, improves the distribution of temperature in the passenger room and greatly improves the riding comfort.

Description

technical field [0001] The invention relates to an air supply device at the bottom of an air conditioner unit of a rail vehicle, and belongs to the technical field of air supply systems for vehicle air conditioners. Background technique [0002] At present, for the air-conditioning unit of the rail vehicle with the front air outlet embedded, due to the structural characteristics of the air-conditioning unit itself, such as Figure 4 and 5 As shown, there is only an air suction port 10 below it, and there is no air outlet. The air blown by the air-conditioning unit directly leads to the passenger room behind through the connecting air duct 1. There is a problem of air supply blind area in the passenger room space below the air-conditioning unit. Through airflow simulation and According to the actual vehicle measurement results, only the return air from the lower part of the unit cannot meet the passenger's requirements for the temperature field and wind speed field in the pas...
