Problems solved by technology
The rail passenger car has a high degree of airtightness, and the comfort of the environment inside the car and the air quality are completely dependent on the guarantee of the air-conditioning system. Due to the high speed of the rail passenger car, the strong external wind resistance causes drastic changes in the airflow field outside the vehicle, resulting in the air conditioning of the train. The discharge resistance of condensed water in the refrigeration cycle of the unit is very large. In addition, the ventilators of the air-conditioning unit are all high-static pressure fans. water consequences

Embodiment Construction
[0009] figure 1 It is a schematic diagram of the structure of the anti-suckback condensate pipe of the air conditioning unit of the present invention. As shown in the figure, an anti-suckback rubber hose 2 is set at the outlet of the condensate water pipe 1, and a water outlet fine channel 21 is opened on the anti-suckback rubber hose 2. The anti-suckback rubber hose 2 described above is made of silicon rubber material.
[0010] The working principle of the anti-suckback condensate pipe is: when the sum of the static pressure of the air-conditioning unit fan and the water pressure in the condensate pipe is greater than the wind pressure of the external environment, the outlet of the anti-suckback hose is open, and the condensate can be quickly discharged; when the air-conditioning unit When the sum of the static pressure of the fan and the water pressure in the condensate pipe is less than the wind pressure of the external environment, the outlet of the anti-suckback hose will...

The invention relates to a rail train air conditioning unit with an anti-inverse-suction condensate pipe. An outlet of the condensate pipe of the air conditioning unit is sleeved with an anti-inverse-suction rubber hose. A water outlet fine channel is formed in the anti-inverse-suction rubber hose. The air conditioning unit is arranged on a high-speed passenger train. When the train runs at a high speed, the condensate water inverse suction phenomenon of the condensate pipe of the air conditioning unit is avoided, and the problems that waterlogging exists in the air conditioning unit, the reliability of soaked parts is affected, and supplied air contains water due to the fact that condensate water cannot be discharged are effectively solved.
Description
technical field [0001] The invention relates to an air-conditioning unit for rail trains with anti-suction condensed water pipes. Background technique [0002] With the development of society and the advancement of science and technology, rail transit (railway trains, subways, etc.) plays an increasingly important role in today's transportation. After the sixth major railway speed increase in my country, railway passenger transport has entered the high-speed era of more than 250km / h, and the design speed has been increased to 400km / h. The rail passenger car has a high degree of airtightness, and the comfort of the environment inside the car and the air quality are completely dependent on the guarantee of the air-conditioning system. Due to the high speed of the rail passenger car, the strong external wind resistance causes drastic changes in the airflow field outside the vehicle, resulting in the air conditioning of the train. The discharge resistance of condensed water in ...
