Rail car air-conditioner UKW.KD.05-25000S/15000G/3x400V~
Rail car air-conditioner type UKW.KD.05-25000S/15000G/3x400V~ is intended to achieve in the shortest possible time and automatically maintain temperature in the range from 17 °C to 27 °C inside the rail car compartments, at an ambient temperature from -30 to + 50 °C (max. + 55 °C), in order to ensure thermal comfort for the passengers and the crew.
Air-conditioner can be used in two basic variants of operation:
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 registered on an ongoing basis by a temperature sensor connected to the electronic control unit mounted on the control panel of the rail car.
