Abstract

The present invention relates to a refrigerating device comprising two compartments and precisely a first compartment used for the storage of fresh food and a second compartment used for the freezing and storing of foods, a refrigerating circuit comprising a compressor (10), a first and a second evaporators arranged in said first and second compartments, respectively, and a condenser, and also comprising a temperature control system (5), having manual regulation possibility, located in said first compartment. The main feature of the refrigerating device according to the present invention is that automatic regulation means are provided, which operate on the basis of the room temperature so assuring the correct operation in both said two compartments.
