Railway Vehicle Air Conditioners The Railway Vehicle Air Conditioning system is controlled by computers, which controls the room temperature. Temperature sensors are installed in fresh air inlets, air channels, and underneath passenger seats, which transmit temperature to the regulator for processing. One computer regulator controls two air conditioning units, which could be achieved collectively in the pilothouse or separately in each car. This ensures the temperature, relative humidity, air velocity, and cleanliness (mainly refers to the dust and the amount of carbon dioxide in the air) in the passenger compartment maintaining at a specified range, creating a sound environment for passengers. The vehicle A/C system is consisted of five major systems: ventilation system, refrigeration system, heating system, humidification system, and automatic control system. |
