REFRIGERATION CONTROL SYSTEM IN COMBINED REFRIGERATION APPLIANCES

摘要

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).
