Abstract

The invention relates to a domestic refrigeration device having a thermally insulating internal container (3) with an interior chamber (4, 5) which can be cooled, and having a refrigerant circuit system (17) which is connected by means of refrigerant pipelines (20, 20a, 20b) for the purpose of cooling the interior chamber (4, 5) and comprises a compressor (8), a condenser (19), an evaporator (6, 12) and an expansion valve (18) which is arranged between the condenser (19) and the evaporator (6, 12), wherein the expansion value (18) has an electromotively driven adjusting apparatus (22) for changing a flow cross section (25a, 25b, 25c, 25d) which determines the throughflow rate of the expansion valve (18).
