Rail train and air conditioning control system thereof

Abstract

The invention discloses an air conditioning control system of a rail train. The air conditioning control system is characterized in that the air conditioning control system comprises an environment temperature detecting unit, an environment temperature judging unit, a controller central processing unit, a low-temperature vehicle maintenance signal input unit, and an environment temperature jump judging unit; the controller central processing unit is used for controlling the air conditioning control system to be shifted into an equipment heating operation mode when the judging result of the environment temperature judging unit is the high-cold environment condition; and the controller central processing unit controls an air conditioning system to enter into a low-temperature vehicle maintenance mode, and when an anti-freezing judging unit is activated, the controller central processing unit starts an air conditioning system anti-freezing mode preferentially. According to the air conditioning control system, equipment of the air conditioning system can be protected, the batched equipment failure of the air conditioning system at the high-cold zone in winter is avoided, it is ensuredthat the temperature in a compartment containing the end zone can meet the comfort requirement under the high-cold environment operation condition, and frosting of the end zone or a door of the trainis effectively prevented. The invention further discloses the rail train comprising the air conditioning control system.

Description

technical field [0001] The invention relates to the field of rail trains, in particular to an air-conditioning control system for rail trains. In addition, the present invention also relates to a rail train comprising the above-mentioned air-conditioning control system. Background technique [0002] With the continuous development of the railway industry, high-speed EMUs have run through the north and south of the river. However, due to the large difference in climate between the north and the south, for the EMU to cross different climate zones at high speed in a short period of time, it is necessary to do a good job in various adaptive designs and controls. Especially for the air-conditioning system, not only the temperature difference between the north and the south is large, but also special protection measures are required for the maintenance and maintenance of the equipment in winter in the north. In winter in the north, the ambient temperature is extremely low when t...

Problems solved by technology

For low-temperature operating conditions, ordinary vehicles only have antifreeze start-up measures for electrified storage outside the low-temperature warehouse, but do not include control system countermeasures for operation, inspection, and maintenance in low-temperature environments.
