Rail car air-conditioner type
UKW.KB.01-35000SGW/3x400V~ is intended to achieve in the shortest possible time and automatically maintain temperature in the range from 20 °C to 27 °C inside the rail car compartments, at an ambient temperature from -30 to + 50 °C (max. + 55 °C), and recirculation and exchange of the air, combined with its filtration, in order to ensure thermal comfort for the passengers and the crew. Air conditioner is a reusable device, mounted under the rail car, connected to the ventilation system of the rail car and control unit.
Air-conditioner can be used in two basic variants of operation:
- cooling - where the air supplied from the outside into the rail car compartments and internal circuit air is cooled;
- heating - where the air as above is heated.
Uniformity of temperature maintained in the rail car compartments is performed by air-conditioner by the exchange and recirculation of air in the rail car compartments. The temperature is regulated in each compartment individually by switching on or off of the heaters located at the windows. The outgoing temperature from the air conditioner and in each compartment individually is controlled on an ongoing basis by a temperature sensors.
System runs in automatic cycle based on the parameters set by the user in the driver on the control panel of rail car. Air-conditioner is powered by 3x400V ~ of the electrical installation of rail car by the
fuse box and relays.
Rail car air-conditioner is used in rail passenger rail cars e.g. Z2B and 144A.
