The invention relates to an anti-condensation refrigerating
system and method for a refrigerator and the refrigerator. The
system comprises a controller, a
humidity sensor, a
solenoid valve, an
evaporator, a compressor, two or more condensers in serial connection, an anti-condensation
pipe and a capillary tube, wherein the
evaporator, the compressor, the condensers, the anti-condensation
pipe and the capillary tube are connected orderly in sequence to form a refrigerating circulation loop. The
solenoid valve comprises an inlet and a plurality of outlets. The inlet of the
solenoid valve communicates with a
refrigerant outlet of the compressor. The multiple outlets of the solenoid valve communicate with a plurality of
refrigerant outlets of the condensers in a one to one correspondence mode. The
humidity sensor is used for collecting a
humidity value of the ambient environment of the refrigerator and sending the collected humidity value to the controller. The controller is used for receiving the humidity value and controlling the inlet and one of the outlets of the solenoid valve to be opened according to the humidity value or controlling all the outlets of the solenoid valve to be closed according to the humidity value. On-off states of the multiple outlets of the solenoid valve are controlled according to the humidity value fed back by the humidity sensor, accordingly, the temperature of an anti-condensation
pipe is adjusted, and the anti-condensation refrigerating
system takes account of anti-condensation and energy saving.
