Abstract
Metodo per valutare la formazione di brina su un usuale evaporatore (102) in un refrigeratore (l), in particolare del tipo a circolazione forzata d'aria, comprende un mobile in cui è realizzato almeno un vano (100) in corrispondenza della quale è posto l'evaporatore (102) ed almeno una ventola (3) atta a generare una circolazione d'aria nel vano (100) suddetto congiuntamente ad un usuale organo convogliatore (106) atto a riportare tale aria da tale vano (100) sull'evaporatore (102) così da raffreddarla nuovamente. Il metodo comprende la valutazione della variazione della portata d'aria che lambisce l'evaporatore (102) ed in funzione di ciò risalire alla quantità di brina presente sull'evaporatore (102) e quindi procedere all'eventuale sbrinamento di quest'ultimo.Method for evaluating the formation of frost on a usual evaporator (102) in a chiller (1), in particular of the forced air circulation type, comprises a cabinet in which at least one compartment (100) is made in correspondence with which it is the evaporator (102) and at least one fan (3) suitable for generating an air circulation in the aforesaid compartment (100) together with a usual conveyor member (106) adapted to return this air from this compartment (100) to the evaporator (102) so as to cool it again. The method includes the evaluation of the variation of the air flow that laps the evaporator (102) and according to this, go back to the quantity of frost present on the evaporator (102) and then proceed with the possible defrosting of the latter.
