An electrical room housing electrical and electronic apparatus for operating and controlling electrical motors of an industrial equipment is disclosed. The electrical room includes a cooling device with a first heat exchanger which is arranged with a first set of channels through which is conducted a first flow of air drawn from inside the electrical room. Warm air from inside the electrical room is circulated through the first heat exchanger of the cooling device and returned to the electrical room in a closed loop, and the air temperature in the electrical room is controlled dependent on a setpoint of between 24-40° C. A method for controlling the cooling device to cool the electrical room and one or more computer programs arranged for controlling the cooling device are also described.
