Adjustable distribution air duct for rail transit air conditioner and control method thereof

Abstract

The invention relates to an adjustable distribution air flue for a rail transit air conditioner and a control method of the adjustable distribution air flue. The adjustable distribution air flue comprises a distribution air flue body. An air inlet of the distribution air flue body is connected with an air conditioner unit. The two ends of the of the distribution air flue body are provided with a first air outlet and a second air outlet correspondingly. The adjustable distribution air flue has the characteristics that an air regulation structure used for regulating the air outlet volume of the first air outlet and the second air outlet is installed in the distribution air flue body; the air regulation structure comprises a first flow guide plate and a second flow guide plate which guide outlet air to be discharged through the first air outlet and the second air outlet correspondingly; the upper end of the first flow guide plate is connected with the upper end of the second flow guide plate; the lower end of the first flow guide plate is connected with the lower end of the second flow guide plate through a connection plate; a tooth-shaped guide rail is fixed to the connection plate of the air regulation structure; a servo motor is installed on the outer side of the distribution air flue body; a power output shaft of the servo motor is connected with a gear; and the gear meshes with the tooth-shaped guide rail. According to the adjustable distribution air flue for the rail transit air conditioner and the control method of the adjustable distribution air flue, air distribution in a carriage can be optimized, and the noise level in the air flue can also be lowered effectively.

Description

technical field [0001] The invention relates to a distribution air duct and a control method thereof, in particular to an adjustable distribution air duct for a rail transit air conditioner and a control method thereof. Background technique [0002] In the mode of urban rail transit system, light rail transit has been paid more and more attention because of its fast, convenient, low investment, quick effect, and low environmental pollution. Compared with the subway of traditional urban rail transit, light rail transit has the characteristics of humanization, high comfort, low noise, harmonious landscape, energy saving and land saving, and small traffic volume and flexible adaptability to changes in traffic volume. Based on the characteristics of these two types of rail transit, there are certain differences in the supporting air-conditioning equipment. The length of a single subway car is generally 20-24m. The top of the subway car is equipped with an air conditioner at the...

Problems solved by technology

In this way, the air conditioner is generally installed in the middle of the top of the two or three compartments that need to be cooled, but the following technical problems will be encountered in this way: 1. Due to the long distance of the total air supply, it cannot meet the needs of each compartment. According to the requirements of the heat load distribution of the air supply volume, at the same time, because the compartments are relatively isolated from each other, the temperature difference between the compartments is caused, and the comfort of the passengers in different areas is different; 2. When the vehicle is not full, the compartments The number of people is different, the proportion of the air supply volume of the air conditioner to each compartment through the air duct is the same as that of the full occupancy design situation, and because the fresh air volume will be mixed in proportion to the air supply volume and sent to the compartments together in the design, the fresh air volume ratio of each compartment It will also be the same as the case of full occupancy design, so that the air supply volume and fresh air volume of each compartment cannot meet their respective needs, some compartments are excessively supplied with air, wasting the energy consumption of the unit, and the air supply volume of some compartments is small, but cannot meet The demand for cooling and fresh air reduces the comfort of passengers; 3. Due to the large cooling capacity of a single air conditioner, the corresponding total air supply volume is also large, and the air flow noise in the air duct is also relatively large, so the noise control in the air duct is also a need to optimize solved problem
