<p>The method is essentially characterised in that a sensitive element is arranged on the surface, which sensitive element initially takes on a temperature substantially corresponding to that of the surface, and a first heating phase, up to a temperature greater than the temperature of the surface, then a cooling phase, down to a temperature lower than the temperature of the surface, are caused on this sensitive element, and a comparison is made between the ratio of the duration of the first heating phase (to) to the rise in temperature during the heating ( DELTA T) and the ratio of the duration of the cooling phase (t'1) to the decrease in temperature during the cooling, a significant difference between these two ratios being indicative of a risk of condensation on the surface. The device includes all the elements allowing the method to be implemented. It may, in particular, comprise a Peltier effect module. <IMAGE></p> |
