Air duct system for cab of tram

Abstract

The invention discloses an air duct system for a cab of a tram. The system comprises an air blower set, an air supply pipeline system, a diffuser system and an exhaust system, wherein the air supply pipeline system is connected to the air blower set; the air supply pipeline system comprises a top air supply pipeline, a first side air supply pipeline and a second side air supply pipeline, the top air supply pipeline is arranged on a movable door plate located on the top wall of the cab, and the first side air supply pipeline and the second side air supply pipeline are symmetrically arranged ontwo sides of the top air supply pipeline and separately extend to the lower side of a driver console; the diffuser system is connected to the air supply pipeline system; and the exhaust system is usedfor exhausting the cab. In this way, according to the air duct system for the cab of the tram, the air duct system with an optimized cab space arrangement structure is reasonably utilized, so that the uniform environment temperature of the cab is ensured, and the comfort of the cab is improved; and meanwhile, electric devices are not added, the space occupation rate of the cab is not influenced,the energy consumption is reduced, and the later operation cost is saved.

Description

technical field [0001] The invention relates to the technical field of tram ventilation systems, in particular to an air duct system for a cab of a tram. Background technique [0002] The air duct system is to let the air flow in the specified direction, and then send it to the designated area after filtering, cooling / heating treatment, so that the air in the car can circulate, take away the heat (summer) / cooling (winter) in the car, and provide The function of fresh air and exhaust gas. [0003] The existing tram vehicle arrangement module is composed of multiple carriages and driver's cabs with independent spaces, and the air duct system connects each carriage and the driver's cab. However, since the driver's cab has a large front window, the solar radiation heat transmitted to the driver's cab through the large glass front window per unit time is relatively large and easily forms a "heat curtain", which forms a sharp contrast with the temperature at the dark position of ...

AI Technical Summary

Problems solved by technology

However, installing an independent air-conditioning unit and a foot heater in the driver's cab not only takes up space in the driver's cab, but also increases the number of electrical components in the driver's cab, consumes a lot of energy, increases the operating costs in the later stage, and still has the defect of uneven ambient temperature in the driver's cab
