Embodiment Construction

[0029] figure 1 A refrigeration appliance according to a first embodiment of the invention is schematically shown. The refrigerating appliance is a combination appliance and comprises a plurality of temperature zones 1 , 2 , 3 , 4 , typically in the form of compartments in a housing 5 , each closed by a door and separated from one another by thermally insulating walls.

[0030] Each temperature zone 1 , 2 , 3 , 4 has an evaporator 6 , 7 , 8 or 9 which is connected in the refrigerant circuit to a compressor 10 and a liquefier 11 . At least two evaporators, here evaporators 6, 7, 8, are connected in series along a branch 13 of the refrigerant line 12; A branch 14 of the road 13 feeds a further evaporator, here the evaporator 9 .

[0031]Each evaporator 6, 7, 8, 9 and liquefier 11 is respectively combined with a fan 25 for increasing the heat exchange capacity.

[0032] The temperature zones 1, 2, 3, 4 can be divided in a known manner into storage compartments and receiving ev...

Abstract

A refrigeration appliance provided by the invention comprises at least a first and a second temperature zone (1, 2) and a refrigerant circuit that includes a compressor (10), a first evaporator (6) for cooling the first temperature zone (1) and a second evaporator (7) for cooling the second temperature zone (2). The first evaporator (6) is serially connected downstream of the second evaporator (7)in the refrigerant circuit, and a controllable throttle point (21) is arranged upstream of the first evaporator (6) and downstream of the second evaporator (7) in the refrigerant circuit. A compressor controller (29) is designed to control the rotational speed of the compressor (10) on the basis of the temperature in the first temperature zone (1).

Description

technical field [0001] The invention relates to a refrigeration appliance with several temperature zones, in particular a domestic refrigeration appliance, and to a method for operating such a refrigeration appliance. Background technique [0002] A refrigeration appliance with a first and a second temperature zone is known from DE 10 2013 226 341 A1, in which refrigeration appliance the refrigerant circuit comprises a compressor, a first evaporator for cooling the first temperature zone and a second An evaporator is connected in series and serves to cool the second evaporator of the second temperature zone, and a controllable expansion valve is connected in front of each evaporator in the refrigerant circuit. [0003] In this known refrigerating appliance, if there is an unmet cooling demand in a temperature zone, the throttling is increased on the controllable expansion valve placed in front of the evaporator in this temperature zone, so that the evaporation involved The ...
