In order to improve the energy balance for air cooling in equipment cabinets, in particular cabinet arrangements in computer centres and server rooms, regulation of the fans for the cooling air circuit is proposed, by means of which precisely the required amount of cooling air can be made available in the induction area to the electronic module units, in particular servers, in the equipment cabinets. According to the invention, at least one leakage air flow is formed between a cold air channel and an exhaust air channel, and is provided with a temperature sensor. The temperature measurement indirectly measures the flow direction and acts as a reference variable for regulating the rotation speed of the fans which, in particular, are arranged in the exhaust air channel. Regulation of the fan rotation speed matches the volume flow of the cooling air circuit to the volume flow actually required by the electronic module units, and therefore reduces the electricity consumption.
