Abstract:
Method for controlling the temperature of a refrigeration unit having a refrigerating compartment, a freezing compartment and a common evaporator of a cooling circuit, the method having first and second modes, the method comprising the steps of, in the first mode, and in dependence on the refrigerating compartment temperature, turning the compressor of the cooling circuit ON when cooling is required and OFF when cooling is not required, and in the second mode, in spite of no cooling requirement in the refrigerating compartment, forcing the compressor ON for a predetermined operating time when OFF-time of the compressor has exceeded a threshold value, repeating the forced turning ON of the compressor as often as the OFF-time exceeds the threshold value, and returning to the first mode as soon as the refrigerating compartment requires cooling.
