Abstract

Bei einem Verfahren zum Abtauen von Verdampfern (4) in Wärmepumpen- und Kältemaschinenanlagen wird der vom Verdichter (1) zum Verflüssiger (2) und über Drosselven­ til (3) und Verdampfer (4) zurück zum Verdichter (1) führende Arbeitsmittelkreislauf (5) geändert und das Arbeitsmittel vom Verdichter (1) unter Umgehung des Verflüssigers (2) dem Verdampfer (4) zugeleitet. Während des Normalbetrie­ bes werden das Arbeitsmittel als Wärmequelle für einen Wärmespeicher (8) und während des Abtaubetriebes der Wärmespeicher (8) als Wärmequelle für das Arbeitsmittel genützt.
Um mit geringem Aufwand den Wirkungsgrad des Abtauvorganges zu verbessern, dient die Abwärme des den Verflüssiger (2) verlassenden Arbeitsmittelkondensats zum Laden des Wärmespeichers (8) und beim Abtauen wird mit der gespeicherten Wärme das durch Wärmeabgabe im Verdampfer (4) verflüssigte und im Drosselventil (3) entspannte Arbeitsmittel verdampft.
