A method for operating a refrigeration appliance includes the steps of running a compressor and opening at least one of a first branch and a second branch, where the first branch has a first evaporator, the second branch has a second evaporator, and the first branch and the second branch are connected in parallel at inlets thereof. The method further determines, according to an ambient temperature, whether the first branch is open after the compressor is turned off and determines, based on the ambient temperature, whether the second branch is open after the compressor is turned off.
