Abstract

Die vorliegende Erfindung betrifft ein Kühl- und/oder Gefriergerät mit wenigstens einem Kältemittelkreislauf mit zwei oder mehr als zwei parallel verschalteten Verdampfern (30;40;50), die vorzugsweise unterschiedliche Kompartimente des Kühl- und/oder Gefriergerätes kühlen, mit wenigstens einem Verdichter (70), mittels dessen Kältemittel zu den Verdampfern gefördert wird, sowie mit wenigstens einer in mehrere Stellungen bewegbaren Steuereinrichtung (20), die in Strömungsrichtung des Kältemittels stromaufwärts der Verdampfer (30;40;50) angeordnet und derart ausgeführt ist, dass sie das Kältemittel auf die Verdampfer verteilt, wobei die von den Verdampfern abführenden Leitungen des Kältemittelkreislaufes miteinander kommunizieren und keine Absperrmittel aufweisen.

Figure imgaf001
The present invention relates to a refrigerator and / or freezer having at least one refrigerant circuit with two or more than two parallel connected evaporators (30; 40; 50), which preferably cool different compartments of the refrigerator and / or freezer, with at least one compressor ( 70), by means of which refrigerant is conveyed to the evaporators, and with at least one control device (20) which can be moved in a plurality of positions, which is arranged upstream of the evaporator (30; 40; 50) in the flow direction of the refrigerant and is designed such that it carries the refrigerant distributed to the evaporator, wherein the laxatives from the evaporator lines of the refrigerant circuit communicate with each other and have no shut-off.
