Abstract

Bei einer Wärmepumpe (1) mit Luft als Wärmequelle ist eine Vorrichtung zur Kältemittelkreisumkehr (6) vorhanden, um den Verdampfer (15) abzutauen. Mit einem Abtaudruckwächter (19) zwischen dem Expansionsventil (14) und der Vorrichtung zur Kältemittelkreisumkehr (6) wird das Ende des Abtauvorgangs erkannt. Bei einem Verfahren zum Betrieb einer Wärmepumpe mit Luft wird der istwert eines Signals eines Drucksensors, der zwischen der Vorrichtung (6) und dem Expansionsventil (14) geschaltet ist, mit einem Wert verglichen und bei Überschreitung des Wertes das Ende des Abtauvorgangs eingeleitet.
