Air conditioner for high-speed magnetic levitation train

Abstract

The invention discloses an air conditioner for a high-speed magnetic levitation train, which comprises an indoor unit and an outdoor unit. The indoor unit comprises an indoor unit case body, a mixing cavity, an air supply cavity, a mixing cavity temperature sensor, an air supply cavity temperature sensor and a carriage temperature sensor; the mixing cavity and the air supply cavity are formed in the indoor unit case body; a fresh air duct is formed in the mixing cavity and is connected with a fresh air valve; an air supply fan, a filter, an evaporator and an exhaust fan are arranged on the indoor unit case body; one side of the evaporator is fixedly connected with an electric heater; the outdoor unit comprises a compressor, a condenser, a liquid storage and a drier-filter; one side of the condenser is provided with a condensate fan; an electrical control cabinet is arranged on the side wall of the indoor unit case body; and an air conditioner control system is arranged in the electrical control cabinet. The air conditioner for the high-speed magnetic levitation train has a compact structure, is novel and reasonable in design and convenient and rapid to use and operate, has high working reliability, a stable operating state, strong refrigerating capacity and strong adaptability, saves cost, has strong practicality and is convenient to popularize and use.

Description

technical field [0001] The invention relates to the technical field of air-conditioning devices, in particular to an air-conditioning device for high-speed maglev trains. Background technique [0002] The localization process of maglev trains is underway. In the early stage, the maglev air conditioners in the Hongqiao-Pudong section will be mass-produced in the Shanghai-Hangzhou line maglev air-conditioning project in the later stage. At the same time, with the rapid development of my country's high-speed railways, the localization of air-conditioning devices for maglev trains is imminent. However, due to the high purchase cost of air-conditioning devices for German trains, and the sharp drop in heat exchange capacity when the trains are running at high speeds, the effect of air-conditioning devices has deteriorated. , can not meet the thermal load requirements in hot summer conditions, the temperature inside the car will rise, and cannot meet the comfort requirements in the ...

At the same time, with the rapid development of my country's high-speed railways, the localization of air-conditioning devices for maglev trains is imminent. However, due to the high purchase cost of air-conditioning devices for German trains, and the sharp drop in heat exchange capacity when the trains are running at high speeds, the effect of air-conditioning devices has deteriorated. , cannot meet the heat load requirements in hot summer conditions, the temperature inside the car will rise, and cannot meet the comfort requirements in the car

In addition, the maglev trains imported from Germany will generate pressure waves when two high-speed maglev trains traveling head-on merge or when the trains quickly enter the tunnel, which will make it difficult to adjust the fresh air and fail to achieve a good cooling effect, resulting in working in midsummer relatively low passenger room temperature
