Refrigeration system for refrigerator, refrigerator and refrigerator control method

Abstract

The invention provides a refrigerating system used for a refrigerator. The refrigerating system used for the refrigerator comprises a compressor, a condenser, a switching unit and a controller, wherein the inlet of the condenser is connected with the outlet of the compressor, the switching unit comprises an inlet, a first outlet and a second outlet, the inlet of the switching unit is connected with the outlet of the condenser, the first outlet of the switching unit is connected with the inlet of the compressor through a first variable temperature evaporator and a refrigeration evaporator in sequence, the second outlet of the switching unit is connected with the inlet of the compressor through a second variable temperature evaporator, the first variable temperature evaporator and the refrigeration evaporator in sequence, the controller is used for controlling the switching unit to be switched to the first outlet when a set temperature of a variable temperature chamber is higher than or equal to a preset temperature so that refrigeration of the variable temperature chamber can be achieved through the first variable temperature evaporator, and the controller is also used for controlling the switching unit to be switched to the second outlet when the set temperature of the variable temperature chamber is lower than the preset temperature so that refrigeration of the variable temperature chamber can be achieved through the first variable temperature evaporator and the second variable temperature evaporator. The refrigerating system used for the refrigerator has the advantages that the temperature difference refrigerating capacity of the variable temperature chamber of the refrigerator can be improved, and wide-range temperature change of the variable temperature chamber of the refrigerator is achieved. The invention further provides the refrigerator and a control method of the refrigerator.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration system for a refrigerator, a refrigerator and a control method for the refrigerator. Background technique [0002] At present, the cooling capacity of direct cooling refrigerator products is about 17 degrees, that is, -7°C-10°C. With the improvement of people's living standards, users have higher and higher requirements for food storage. Therefore, the current The cooling capacity of some refrigerators with variable temperature and room temperature difference can no longer meet the needs of users. Contents of the invention [0003] The present invention aims to solve at least one of the above-mentioned technical problems. [0004] Therefore, an object of the present invention is to provide a refrigeration system for a refrigerator, which can improve the cooling capacity of the variable temperature room temperature difference of the refrigerator,...
