Abstract: By means of the present invention, a cooling device (9) is realized, that prevents the fresh food compartment (10) to be cooled unnecessarily while the door (12) of the fresh food compartment (10) is open, that prevents formation of frost on the first evaporator (7) even when the user keeps the door (12) of the fresh food compartment (10) open frequently and/or for a long time while the compressor (1) is operating, thus decreasing the requirement of performing a special defrost cycle, furthermore that directs the refrigerant fluid only to the freezing compartment (11) while the door (12) of the fresh food compartment (10) is open during the refrigeration cycle, enabling preferably to maintain additional cooling in the freezing compartment (11), that enables the compressor (1) to be used more effectively, enabling a more effective refrigeration to be performed and hence providing energy saving.
