摘要:The invention refers to an arrangement at a refrigerator cabinet (10) having anabsorption refrigerating apparatus (16,18) operated by a heating cartridge (40) from atleast one electric current source or by a gas burner (38). The arrangement shows acontrol apparatus (74) which automatically starts the gas burner (38) when the supply ofcurrent to the heating cartridge (40) ceases. The refrigerating apparatus (18) is withexception of its evaporator (16) enclosed in a heat insulated chamber (20) through whichsurrounding air circulates for cooling of the refrigerating apparatus (18). In order toprevent the refrigerant in the refrigerating apparatus from freezing to plugs at lowtemperature of the surrounding air, which plugs put the refrigerating apparatus out offunction, means (86) are arranged to limit the air circulation through the chamber (20) anda temperature sensing means (80) is located in the chamber for breaking the current tothe heating cartridge (40) at a certain low temperature in the chamber (20) so that thegas burner (38) is put into operation.
