Abstract

In a refrigerator having a freezer box and a refrigerant circuit, which has a compressor (21) and a first evaporator (33, 63), wherein the first evaporator is arranged downstream of a stop valve (36,67) and a first capillary tube (31, 61), the first evaporator (33, 63) is arranged upstream of a gas valve (68). A method for operating a refrigerant circuit, in a refrigerator having a freezer box, has the following method steps in any sequence: a) operating (81) the compressor; b) operating (82) a stop valve before a first evaporator; c) operating (83) a gas valve after the first evaporator.

Description

technical field [0001] The invention relates to a refrigeration appliance, in particular a domestic refrigeration appliance, with a freezer compartment and a refrigerant circulation system, and to a method for operating such a refrigeration appliance, and in particular to a refrigeration appliance that can be used in the refrigeration appliance The structure of the refrigerator. Background technique [0002] A refrigeration appliance is known from DE 10 2014 211 133 with a first and a second evaporator which are each arranged in parallel with each other in a refrigerant circuit together with an upstream throttling point. in a branch circuit, wherein a check valve is arranged on the output of the second evaporator, and in one configuration, a first throttling point connected upstream of the first evaporator is capable of switch between, wherein the input line to these two throttle points can be shut off. [0003] In such refrigerating appliances with a freezer compartment e...
