ABSTRACT:

This invention relates to a defrosting device, in particular for refrigeration systems.
In refrigeration units, the finned assembly is defrosted by the use of heating elements in contact with the assembly itself. Said heating elements are in the form of electrical resistance elements, which are powered at predetermined time intervals for a constant period. If excessive heating occurs, a safety thermostat ensures that the items contained in the refrigeration unit remain preserved, by deactivating the heating elements.
This known defrosting system has the drawback of non-optimum defrosting of the finned because the powering of the heating elements is not correlated with the effective presence of frost. This can result in:
activation of the heating elements even if frost is not present on the finned assembly, with consequent energy consumption and increase in the temperature of the environment, resulting in damage to the food,
inefficient heat transfer by the refrigeration assembly due to the presence of frost because of delay in operation of the heating elements.
This drawback is eliminated according to the invention by a device for defrosting the finned cooling assembly of a refrigeration system as described in claim
