Method and equipment for the thermal conditioning of cabinets containing electronic assemblies, in which a logic control unit (12), determines the choice of one out of three cooling conditions, based on the temperature conditions outside the cabinet (1) to be air-conditioned: a closed circuit mechanical cooling of the air drawn from the cabinets, if the outside is higher than a first threshold; an open circuit free ventilation cooling, if the outside temperature is lower than a second threshold; mixed cooling, in which external air is mixed with the internal one, if the temperature is included between the two thresholds. <IMAGE> |
