Abstract
A method for determining the level of efficiency of a ventilation system of an electrical enclosure intended to house one or more electrical devices, the method including a learning step including a step for determining a profile of the power dissipated via the Joule effect by each electrical device, an evaluation step for evaluating the level of efficiency of the ventilation system, including a step for determining the average air flow rate of a fan from a profile of the temperature of the air outside the enclosure obtained over an evaluation period, a profile of the temperature of the air at the outlet of the enclosure, and the dissipated power profile determined during the learning step, a step for comparing the average air flow rate with one or more threshold values in order to determine the level of efficiency of the ventilation system.
