Anti-condensation refrigerating system and method for refrigerator and refrigerator

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of refrigerator refrigeration, in particular to a refrigerator anti-condensation refrigeration system and method, and a refrigerator. Background technique [0002] Since the indoor temperature of the refrigerator is usually much lower than the ambient temperature where the refrigerator is placed, condensation often occurs at the contact between the refrigerator door and the door frame, causing adverse effects on users. In order to solve the condensation generated at the contact between the refrigerator door and the door frame, an anti-condensation device is usually provided in the interlayer of the door frame, and the anti-condensation device generally adopts an anti-condensation tube. Taking a conventional direct-cooling refrigerator as an example, during cooling, the refrigerant passes through the first condenser, the anti-condensation tube, the second condenser, and the dry filter in turn from the compres...

Problems solved by technology

However, for users in the Yangtze River Basin and coastal areas, due to high humidity, especially in the rainy season, the maximum humidity is as high as 90%. The temperature cannot be adjusted higher, and the problem of condensation will still occur

[0004] In order to solve the problem of anti-condensation in refrigerators under high humidity environment, some products may use figure 2 The improved refrigerating system shown is that the pipelines of the first condenser and the anti-condensation pipe are exchanged in sequence, and the refrigerant passes through the anti-condensation pipe, the first condenser, the second condenser, the drying The filter can increase the temperature of the anti-condensation pipe to solve the problem of condensation, but at the same time, due to the high temperature of the anti-condensation pipe, it cannot be adjusted under the normal humidity environment, which will increase the heat load of the refrigerator, which will increase the power consumption of the refrigerator
