Abstract

Die Erfindung betrifft eine Abtaueinrichtung für meh­ rere Kälteanlagen mit jeweils einem Kältemittelkreis, der einen Verdichter, einen Kondensator und einen Ver­ dampfer aufweist. Um ein einfaches Abtauen zu erzielen, ist jeder Verdampfer mit einer zusätzlichen Berohrung oder einem kleinflächigen Verflüssiger versehen, wobei jeweils die Berohrung oder der Verflüssiger für den Verdampfer eines Kältemittelkreislaufs mit der Hochdruckseite eines Verdichters eines weiteren Kältemittelkreislaufs ventilge­ steuert verbindbar ist. The invention relates to a defrost device for meh Other refrigeration systems with one refrigerant circuit each a compressor, a condenser and a ver has steamer. To achieve easy defrosting is any vaporizer with additional tubing or a small-area condenser, where each the pipe or the condenser for the evaporator of a refrigerant circuit with the high pressure side of one Compressor of another refrigerant circuit valve controls is connectable.
