Abstract

The invention discloses a layered ventilation system of a subway air conditioner terminal. The layered ventilation system comprises an air conditioner refrigerating unit, an air supply module and an air exhaust module. The air supply module is composed of an air supply main pipe, a plurality of first air supply branch pipes, a plurality of transverse air supply branch pipes and a plurality of second air supply branch pipes. The air-conditioning refrigerating unit is connected with the air supply main pipe; the main air supply pipe is transversely arranged on the upper portion of a subway carriage and provided with a main pipe air supply outlet. The first air supply branch pipe is communicated with the air supply main pipe; one end of the transverse air supply branch pipe is communicated with the bottom of the first air supply branch pipe, the transverse air supply branch pipe is located in the longitudinal middle of the subway carriage, and a branch pipe air supply opening is formed in the transverse air supply branch pipe; the bottom of the second air supply branch pipe is communicated with the other end of the transverse air supply branch pipe; and the top of the second air supply branch pipe communicates with the air supply main pipe. The layered ventilation system has the advantages that the problem that people in the middle and lower portions of a compartment cannot directly breathe in fresh air is solved, and sitting and child passengers can breathe fresh air.

Description

technical field [0001] The invention relates to the technical field of subway car air conditioners, in particular to a layered ventilation system at the end of a subway air conditioner. Background technique [0002] With the rapid development of urbanization in China, the urban population density is increasing rapidly. As an indispensable tool for transportation, subway has the advantages of convenience, high speed and large passenger capacity. At present, the air supply and exhaust system in the subway car generally adopts the form of upward supply and upper row, that is, the air supply duct is arranged on the top of the car, and the fresh air is sent into the car through the air supply port in the form of a louver grille, and at the same time, the dirty air in the car is passed through the top side. The exhaust outlet of the car is discharged outside the car. At present, the market also adopts the structure of setting the air outlet under the seat of the car to discharge t...
