Abstract

Bei einem Verfahren zum Überwachen eines Kompressionskältekreises mit zumindest einem Verdichter (1), einem Kondensator (2), einer Drossel (3) und einem Verdampfer (4) wird der Druck pH auf der Hochdruckseite zwischen Verdichter (1) und Drossel (3) erfasst wird, die Siedetemperatur T'H auf der Hochdruckseite als Funktion des Druck auf der Hochdruckseite pH und des Kältemittels berechnet wird, die Temperatur TH zwischen Kondensator (2) und Drossel (3) erfasst wird, die Temperaturdifferenz ATH zwischen T'H und TH gebildet wird und in dem Fall, in dem die Temperaturdifferenz ΔTH einen vorgegebenen Grenzwert erstmals unterschreitet ein Fehlerstatus aktiviert wird und in dem Fall, in dem die Temperaturdifferenz ΔTH den vorgegebenen Grenzwert wiederholt mit einer vorgegebenen Anzahl unterschreitet, der Kompressionskältekreis abgeschaltet wird.
