Abstract

Die vorliegende Erfindung betrifft ein Kühl- und/oder Gefriergerät mit wenigstens einem gekühlten Kompartiment und mit wenigstens einem Kältemittelkreislauf, der wenigstens einen Kompressor und wenigstens einen Verdampfer zur Kühlung des genannten Kompartimentes sowie wenigstens eine in Strömungsrichtung des Kältemittels stromaufwärts des Verdampfers angeordnete Kapillare aufweist, wobei der Kältemittelkreislauf ein stromaufwärts der Kapillare angeordnetes Ventil aufweist, das mit der Kapillare derart in Verbindung steht, wobei die Kapillare je nach Ventilstellung mit Kältemittel durchströmt wird, und wobei wenigstens eine Steuer- oder Regelungseinheit vorgesehen ist, die mit dem Ventil in Verbindung steht und die derart ausgeführt ist, dass sie die Ventilstellung in Abhängigkeit von dem in dem Kompartiment herrschenden Kältebedarf einstellt.

Figure imgaf001
The present invention relates to a refrigerator and / or freezer with at least one refrigerated compartment and at least one refrigerant circuit having at least one compressor and at least one evaporator for cooling said compartment and at least one upstream of the evaporator in the flow direction of the capillary arranged capillary the refrigerant circuit has a valve arranged upstream of the capillary, which communicates with the capillary in such a way, with the capillary being flowed through depending on the valve position with refrigerant, and wherein at least one control or regulating unit is provided, which communicates with the valve and the is designed such that it adjusts the valve position in response to the cooling demand prevailing in the compartment.
