Abstract

The invention discloses a refrigerating and defrosting control method for a dual-system refrigerating refrigerator. A refrigerating chamber, a freezing chamber and a dual-system refrigerating system are arranged in the dual-system refrigerating refrigerator. The refrigerating and defrosting control method comprises the steps that when a compressor meets a starting condition, whether the refrigerating chamber or the freezing chamber is in a defrosting state at the current moment or not is judged, and if yes, the defrosting state is started; and if not, whether the refrigerating chamber or the freezing chamber is in the refrigerating state at the current moment or not is judged. According to the refrigerating and defrosting control method, when the refrigerating chamber is defrosted, a refrigerating evaporator is defrosted in the mode that a refrigerating fan drives the air in the refrigerating chamber to exchange heat with the refrigerating evaporator, so that the defrosting function of the refrigerating chamber in a non-heating mode is achieved, the input cost of a refrigerating and defrosting heating pipe can be reduced, and on the other hand, the refrigerating chamber is not provided with a defrosting heating pipe to consume defrosting power, so that the overall energy consumption of a refrigerator can be greatly reduced, and meanwhile, the temperature fluctuation range of the refrigerating chamber can be reduced.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a method for controlling refrigeration and defrosting of a dual-system refrigeration refrigerator. Background technique [0002] Dual-system refrigeration refrigerator refers to a refrigerator with one compressor and two evaporators in the refrigerator refrigeration system. The refrigeration evaporator is placed in the refrigerator compartment, and the freezing evaporator is placed in the freezer compartment. In the refrigerator room and the freezer room, the circulating fan drives the indoor air to exchange heat with the respective evaporators to achieve room cooling. Compared with the single-system refrigerator, the air in the dual-system refrigerator can circulate independently in each room to prevent The food smells between the refrigerator and the freezer, and at the same time, the temperature control of each room is more precise. [0003] When the air-coo...
