Abstract
A refrigeration appliance includes first and second temperature zones and a refrigerant circuit having first and second parallel branches. The first branch has a controllable first restriction point and a first heat exchanger for setting a temperature of the first temperature zone, and the second branch has a second restriction point and a second heat exchanger for setting a temperature of the second temperature zone. A branching point, at which the refrigerant circuit splits into the two branches, is configured as a separator for separating gas and liquid and the second branch is connected to a liquid outlet of the separator.
