A refrigerated preservation unit, particularly for domestic use, includes an internal compartment provided with an access door and with a refrigeration means. The unit includes an atmosphere control device constituted by a nitrogen generator, a control PLC, an oxygen analyzer, an overpressure/negative pressure valve, and a flexible plenum chamber. These components are all installed in a lower region of the unit, in the compartment normally used to accommodate the compressor and the condenser in traditional domestic refrigerators. The present invention allows to considerably improve the preservation times of food products stored inside home refrigerators when they are preserved loose and/or when the packages that contain them are not hermetically closed. The present invention allows in some cases to even treble the preservation time of the preserved products with a minimal additional energy expenditure of the electrical appliance.
