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-back-sucking condensate pipe. The exit of the condensate pipe of the air-conditioning unit is sleeved with an anti-back-suckingrubber hose, and a water outlet thin channel is formed in the anti-back-sucking rubber pipe. The rail train air-conditioning unit with the anti-back-sucking condensate pipe is arranged at high-speedtrains, the phenomenon of condensate water back-sucking of the condensate pipe of the air-conditioning unit does not happen when trains run at high speed, the problems that water is stored in the air-conditioning unit, the reliability is affected when assembly units touch water and air is supplied with water can be effectively prevented.
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 ...
