A refrigeration appliance with multiple storage compartments has a refrigerant circuit with a first expansion valve, a first heat exchanger, a second expansion valve, and a second heat exchanger connected in series between pressure and suction connections of a compressor. Each heat exchanger is associated with at least one storage compartment in order to control its temperature. A control unit controls the compressor rotational speed and positions of the expansion valves. The control unit has a continuously linear regulator for each storage compartment with a P-component for estimating a required temperature control output using a difference between actual and target temperatures. A model computing unit ascertains a target evaporation temperature for a first storage compartment controlled by the first heat exchanger, and for a second storage compartment controlled by the second heat exchanger. The heat exchangers are operated by selecting the compressor rotational speed and the valve positions of the expansion valves.

Refrigeration appliance with compartment which can be used in a variable manner

A refrigeration device has a first storage chamber, a second storage chamber and a refrigerant circuit, in which a first controllable throttle point, a first heat exchanger for controlling the temperature of the first storage chamber, a second controllable throttle point and a second heat exchanger for cooling the second storage chamber are connected in series between a pressure connection and a suction connection. A hot line section, located upstream of the second heat exchanger, and a cold line section, located downstream of the second heat exchanger, are routed in thermal contact with respect to one another in order to form an internal heat exchanger. The first heat exchanger is connected to the pressure connection bypassing the hot line section.

Refrigeration device comprising multiple storage chambers

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.
