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).
Claims
1. A refrigeration control system in combined refrigeration appliances of the type comprising: a refrigerating compartment (R) provided with at least one refrigerating compartment temperature sensor (Sr) ; a freezing compartment (F) provided with a freezing compartment temperature sensor (Sf) ; a compressor
(60) ; an evaporator (20) ; a refrigerating compartment fan (40) and a. freezing compartment fan (50) to produce respective forced air flows through the evaporator (20) and through the refrigerating compartment (R) and the freezing compartment (F) , respectively,- and a control means (30) to activate and deactivate the compressor (60) and the refrigerating compartment fan (40) and freezing compartment fan (50) 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) , character!zed in that 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) detected by the refrigerating compartment temperature sensor (Sr) reaches a deactivation value of the refrigerating compartment fan (40) at the same time in which the temperature of the freezing compartment (F) detected by the freezing compartment temperature sensor (Sf) reaches a deactivation value of both the freezing compartment fan (50) and the compressor (60) , said selective and periodic adjustment of the speed of the refrigerating compartment fan (40) occurring whenever the ratio between the cooling detected in the refrigerating compartment (R) and measured from the
AIVIENDED SHEET(ARTlCLEIg) activation temperature and the maximum cooling defined between the activation (Tar) and deactivation (Tdr) temperatures of the refrigerating compartment fan (40) differs by an absolute value higher than a determined balance value from the ratio between the cooling in the freezing compartment (F) measured from the activation temperature and the maximum cooling defined between the activation (Taf) and deactivation (Tdf) temperatures of the freezing compartment fan (50) .

7. The refrigeration control system according to claim i, characterized in that the control means (30) compares the cooling ratios of both the refrigerating compartment (R) and the freezing compartment (F) at each period of about one to five minutes, in order to detect the need for adjusting the speed of the refrigerating compartment fan (40) .

10. The refrigeration control system according to claim 9, characterized in that the control means (30) reduces the deactivation temperature (Tdr) of the refrigerating compartment (R) during at least one operating cycle of the latter, whenever it is activated for at least two consecutive times, with the temperature of the refrigerating compartment (R) being situated between the activation temperature (Tar) of the refrigerating compartment fan (40) and the
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" .
