High-efficiency vehicle-mounted ventilation system

Abstract

The invention provides a high-efficiency vehicle-mounted ventilation system which comprises a wind inlet unit, a wind outlet unit and a control unit, wherein the wind outlet unit comprises an unpowered blower and a pipeline and is installed at the middle rear part of the vehicle roof, and the pipeline is directly connected into a carriage; and the wind inlet unit is a ventilation pipe with a curved head and is positioned at the front part of the vehicle roof, the direction of the pipe head faces the direction of the vehicle head, and a small ventilator which can be independently controlled isarranged at the position of the pipe head. When the vehicle is started, air flow drives the unpowered blower to rotate and simultaneously carry the hot air in the vehicle away, and the ventilation pipe replenishes fresh air into the carriage, thereby forming natural air circulation in the carriage. If necessary, the ventilator can be opened to accelerate the ventilation rate. The invention has theeffects that after the unpowered blower is arranged, the air flow force generated by running of the vehicle drives the unpowered blower to quickly carry the hot air in the vehicle away, thereby performing the action of quick ventilation; and the ventilator can accelerate the ventilation rate and can centrifugally throw away rain water and the like.

Description

technical field [0001] The invention relates to a ventilation system, in particular to a high-efficiency vehicle ventilation system. Background technique [0002] With the progress of human civilization and the development of industry, the development of air-conditioned passenger cars in the past ten years is obvious to all, such as double-decker passenger cars, air-conditioned passenger cars, subway vehicles, and maglev trains. The proportion of express trains has increased significantly. Passenger trains are developing towards high speed and comfort, and passenger air-conditioned trains are increasing year by year. The high speed and comfort of passenger cars put forward higher requirements for the air conditioning and ventilation system of passenger cars. The comfort level of the environment in the passenger car is directly related to the quality of travel life of passengers. The continuous improvement of people's living standards makes people have higher and higher re...

Problems solved by technology

[0004] The ventilation in the current passenger car mainly depends on the air conditioning system, and the function of the air conditioning system generally plays a certain role when the weather is cold or hot. If it is spring and autumn, the air conditioner is generally not turned on, and the ventilation in the car is not very good. it is good
