Abstract
A device for defrosting the finned cooling assembly (17) of a refrigeration system, characterised by comprising: an ellipsoid (2, 26) of transparent polymer materiel housing a light source (6, 32) positioned substantially in correspondences with one of the focal points, and a sensor (12, 30) for the light beam radiated by said source and reflected by the inner surface of the ellipsoid, a plurality of heating and defrosting elements (18) for the finned cooling assembly (17), which are activated by a signal emitted by the sensor (12, 30) when this senses a variation in the luminous intensity of the beam, said variation in luminous intensity of the beam being caused by the formation of frost along the path of the light beam.
