Patent ID: 7895851

Claim:
A method for controlling the humidity inside a refrigerator, the refrigerator comprising at least a cavity and a refrigeration circuit including a fan inside the cavity for allowing a forced air circulation inside the cavity, an evaporator and a compressor, the method comprising: measuring, directly or indirectly, a relative humidity level inside the cavity; measuring, directly or indirectly, a temperature of the evaporator; and feeding the relative humidity level and evaporator temperature to a control algorithm capable of driving the refrigeration circuit in order to maintain an average level of relative humidity substantially constant and corresponding to a set value, wherein the humidity is controlled inside the refrigerator cavity by acting on the compressor and the fan so that a cooling cycle is provided which is composed of three main phases: a cooling storage phase in which the fan is off and the compressor is on; a cooling distribution phase in which the fan is on with the compressor on until the evaporator has reached a first predetermined temperature; and a warming phase in which the compressor is off, the evaporator has reached a second predetermined temperature higher than the first predetermined temperature and the fan is on or off according to the relative humidity level inside the cavity compared to the set value.
