Rail transit vehicle and air conditioner air supply uniformity self-adaptive adjusting method and system thereof

Abstract

The invention discloses a rail transit vehicle and an air conditioner air supply uniformity self-adaptive adjusting method and system thereof. An air supply duct is of a variable structure, the inclination angle of a partition plate assembly between a first cavity and a second cavity is adjustable, the ventilation quantity of a ventilation assembly is adjustable, and a baffle assembly with ventilation holes is additionally arranged in the first cavity; different passenger capacities correspond to different air supply capacities, the inclination angle of the partition plate assembly and the position of the baffle assembly are adjusted in a self-adaptive mode according to the different air supply capacities, the difference of unit volume air speed airflow at different positions in the first cavity is reduced as much as possible, the ventilation quantity of the ventilation assembly is adjusted in a self-adaptive mode according to the different air supply capacities, the air speed airflow flowing into the second cavity through the ventilation assembly is the same as much as possible, namely the air supply uniformity adjustment of an air supply duct in the length direction is achieved, and the requirement that the air supply uniformity of the air supply duct needs to be kept under the conditions of different passenger capacities and different air supply capacities can be met.

Description

technical field [0001] The invention belongs to the technical field of vehicle air-conditioning control, and in particular relates to a rail transit vehicle and an adaptive adjustment method and system for air-conditioning uniformity of air supply thereof. Background technique [0002] With the rapid development of my country's rail transit field, the thermal comfort of train passenger compartments has attracted more and more attention and attention from passengers and owners. The thermal comfort of the passenger room is closely related to the uniformity of the air supply of the air conditioner. The uniformity of the air supply of the air conditioner largely determines the key indicators such as temperature uniformity, wind speed, and humidity in the passenger room. Therefore, it is important to optimize the uniformity of the air supply of the air conditioner. In terms of application significance, it can greatly improve the passenger's ride experience and intuitive experienc...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a rail transit vehicle and its air-conditioning uniformity self-adaptive adjustment method and system to solve the problem of air duct uniformity under different air supply conditions. The air supply volume of the air supply duct is adaptively adjusted to control the key structure of the first chamber / second chamber in the air supply duct to meet the requirements of the air supply uniformity of the air duct under different air supply volumes of the air conditioner. Improve the adaptability of the uniformity of the air supply of the air conditioner under the condition of passenger capacity, and improve the comfort of the passenger compartment of the vehicle
