Abstract

Il frigorifero comprende almeno due scomparti (1, 2), uno (1) a temperatura minore e l'altro (2) a temperatura maggiore, ed un circuito frigorigeno (8) includente un evaporatore (7) posto in scambio termico con lo scomparto (1) a temperatura minore, un condensatore (10) e un compressore (9) periodicamente disattivabile quando la temperatura all'interno dello scomparto (1) a temperatura minore scende al di sotto di un valore minimo predeterminato. Un ventilatore (16) determina una circolazione forzata di aria attraverso detto evaporatore (7) e all'interno dei suddetti scomparti (1, 2), sono previsti mezzi valvolari (22) che in occasione delle disattivazioni del compressore (9) vengono posti in posizione tale da chiudere lo scomparto (1) a temperatura minore nei confronti di detta circolazione forzata di aria e convogliare tutta l'aria suddetta nello scomparto (2) a temperatura maggiore.(Fig. 1).
