Abstract

A refrigeration control system in combined refrigeration appliances of the type comprising: a refrigerating compartment (R); a freezing compartment (F); a compressor (60); an evaporator (20); a refrigerating compartment fan (40) and a freezing compartment fan (50); and a control means (30) to activate and deactivate the compressor (60) and both the refrigerating compartment fan (40) and the freezing compartment (50) fan as a function of the activation and deactivation temperatures (Tar, Taf, Tdr, Tdf) detected by the refrigerating compartment temperature sensor (Sr) and the freezing compartment temperature sensor (Sf). The control means (30) is operatively associated with the refrigerating compartment fan (40) to selectively and periodically adjust the speed of the latter, so that the temperature of the refrigerating compartment (R) reaches a deactivation value of the refrigerating compartment fan (40) at the same time in which the temperature of the freezing compartment (F) reaches a deactivation value of both the freezing compartment fan (50) and the compressor (60).

9. The refrigeration control system according to claim 1, characterized in that the control means (30) activates the refrigerating compartment fan (40) , even with the compressor (60) being deactivated, when the temperature (Tsr) sensed in the interior of the refrigerating compartment (R) reaches a predetermined temperature limit value higher than the activation temperature (Tar) of the refrigerating compartment fan (40) .

AMENDED SHEET(ARTlCLEIg) 30
predetermined limit value.
11. The refrigeration control system according to claim 1, characterized in that the control means (30) is operationally and selectively conducted by the user to operate in a "vacation mode" , according to which the activation temperatures {Tar, Taf) and the deactivation temperatures (Tdr, Tdf) of both the refrigerating compartment fan (40) and the freezing compartment fan (50) are raised to a less cold condition and the speeds of both the refrigerating compartment fan (40) and the freezing compartment fan
(50) are set to constant and reduced values.
12. The refrigeration control system according to claim 11, character!zed in that the "vacation mode" is maintained by the control means (30) until the occurrence of one of the actions of the user deactivating said mode in an electronic control panel of the refrigeration appliance and of opening any one of the two doors (11, 12) of the cabinet (10) .
13. The refrigeration control system according to claim 1, characterszed in that the control means (30) is operationally and selectively conducted by the user instructing an electronic control panel of the refrigerating appliance to work in a "party mode", according to which the activation (Tar) and deactivation (Tdr) temperatures of the refrigerating compartment fan (40) are reduced to a cooler condition; the activation (Taf) and deactivation (Tdf) temperatures of the freezing compartment fan (50) are kept in the operational condition originally selected by the user for the refrigeration appliance,- the speed of the refrigerating compartment fan (40) is set to a maximum value; and the speed of the freezing compartment fan (50) is maintained in a constant and reduced value. 31
14. The refrigeration control system according to claim 13, characterized in that the "party mode" is maintained by a predetermined period, at the end of which the refrigeration appliance returns to the operating mode prior to the activation of the "party mode" .
