Abstract

L'invenzione si riferisce, in generale, a sistemi elettronici di controllo per condizionatori d'aria, pompe di calore e apparecchiatura di refrigerazione. In particolare, l'invenzione riguarda un apparato e un metodo impieganti un complesso digitale per il controllo del flusso di refrigerante attraverso il sistema di refrigerazione, allo scopo di ottimizzare l'efficienza e di estendere la durata di esercizio dei vari componenti. L'invenzione si caratterizza, in particolare, per l'impiego di un sistema di controllo basato su di un microprocessore e per l'utilizzo di una valvola a controllo numerico.(Fig. 2).
