Embodiment Construction
[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0029] The invention discloses an adjustable air supply control method for a train. By adjusting the speed of the air supply fan of the train air conditioning system and the opening of the return air door and the fresh air door, the pressure of the air duct and the temperature of the air supply are always close to the target value, thereby ensuring the comfort of passengers.
[0030] like figure 1 As shown, the train air conditioning system of the present invention includes an inverter air conditioner 1 , an air duct 2 , a damper 3 , a detection device 4 and an air outlet 5 .
[0031] The inverter air conditioner 1 includes an air conditioner unit 11 , a blowe...

Abstract
The invention relates to a train adjustable air supply control method. When an adjustable air supply port is changed, an initial air supply quantity MS is changed, and a present pressure value P of an air way is deviated from a target pressure value P0; the speed of an air supplier is adjusted until the present pressure value P of the air way is near the target pressure value P0; meanwhile, an initial total air quantity MZ is changed to cause synchronous change of an initial new air quantity Mw; when the new air quantity introduction is not changed, an adjustable new air door openness and an adjustable air return door openness are adjusted; and an effective ventilation area Sw' of the adjusted new air door and an effective ventilation area Si' of the adjusted air return door satisfy Sw' / Si'=a% / (b%-a%). The train adjustable air supply control method has the following advantages: under the precondition of guaranteeing invariable new air introduction quantity, the air pressure of the air way is always near reasonable target value, and the air supply temperature of the air way is always located in reasonable target section, so that the passenger comfort is improved.
Description
technical field [0001] The invention belongs to the technical field of train air conditioning, and in particular relates to a train adjustable air supply control method. Background technique [0002] The air-conditioning system is an important part of the vehicle to meet the comfort requirements of passengers in travel life. The air-conditioning system includes air-conditioning units, air supply systems, fresh air systems, return air systems, exhaust systems and air-conditioning control systems. Through the coordinated work of the above parts, the system realizes multiple functions such as air cooling, heating and ventilation inside the vehicle. [0003] The air supply process of the train is mainly composed of the air supply fan of the air supply system, which mixes the returned air from the cabin of the air conditioner unit and the fresh air outside the vehicle, and then sends it to the air duct of the train after being cooled or heated by the air conditioner unit, and the...
