Abstract

Un refrigeratore, quale un frigorifero domestico o similare, in particolare di tipo a circolazione forzata d'aria, comprende un mobile in cui sono realizzati uno o più vani controllati in temperatura, in corrispondenza di una parete di un vano ove è posto un usuale evaporatore essendo previsto un ventilatore o ventola mosso da un usuale motore elettrico connesso almeno ad una linea di alimentazione elettrica atto a consentire la circolazione dell'aria attraverso l'evaporatore stesso e la ventilazione del vano o dei vani attraverso usuali condotti realizzati nel mobile suddetto. Su tale linea sono posti mezzi interruttori comandati da una unità di comando che ne opera la chiusura e apertura in modo da variare le condizioni di funzionamento della ventola, ed in particolare la sua velocità, essendo previsti mezzi rilevatori generanti un segnale relativo alla condizione di funzionamento della ventola atto ad essere confrontato con un segnale di riferimento, detto confronto generando un segnale di controllo che è indirizzato all'unità di comando che in funzione di esso segnale interviene sui mezzi interruttori regolando, le condizioni di funzionamento della ventola ed in particolare la sua velocità.
