Beschreibung
Zusammenfassung:	Disclosed is a fault diagnostic method for a heat exchanger in which ambient air temperature and heat exchanger temperature are measured. Also disclosed is the use of a single temperature sensor, in combination with a microprocessor, to measure temperature emitted from a heat exchanger and ambient air temperature surrounding the heat exchanger. L'invention concerne un procédé de diagnostic de défaillance pour un échangeur de chaleur, consistant à mesurer la température de l'air ambiant et la température de l'échangeur de chaleur. L'invention concerne également l'utilisation d'un capteur de température unique, en combinaison avec un microprocesseur, pour mesurer la température émise à partir d'un échangeur de chaleur et la température de l'air ambiant entourant l'échangeur de chaleur.
