Abstract

L'invention concerne les pompes à chaleur. Un élément chauffant à résistances 34 est placé sous l'échangeur de chaleur 10 d'une pompe à chaleur, afin de dégivrer périodiquement cet échangeur. Le cycle de dégivrage est déclenché automatiquement par la détection d'une chute de pression d'air excessive entre les extrémités de l'échangeur, du fait de l'obstruction des passages d'air par le givre. Application aux installations de climatisation.The invention relates to heat pumps. A resistance heating element 34 is placed under the heat exchanger 10 of a heat pump, in order to periodically defrost this exchanger. The defrost cycle is triggered automatically by the detection of an excessive air pressure drop between the ends of the exchanger, due to the obstruction of the air passages by the frost. Application to air conditioning installations.
