Air conditioners

Railway roof air-conditioner type UKW.KD.01-5200S/3000G/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 electric locomotive driver’s compartment, at an ambient temperature from -30 to + 50 °C (max. +55 °C), in order to ensure thermal comfort for the crew.

Air-conditioner can be used in two basic variants of operation:

• cooling - where the air supplied from the outside into the driver’s compartment and internal circuit air is cooled;
• heating - where the air as above is heated.

Uniformity of temperature maintained in the driver’s compartment is performed by air-conditioner by the exchange and recirculation of air in the driver’s compartment. The temperature is registered on an ongoing basis by a temperature sensor connected to the electronic control unit mounted on the control panel in the driver’s compartment.
