Control method of dual-system refrigerator

Abstract

The invention relates to a control method of a dual-system refrigerator. The refrigerator comprises a refrigerator body and a refrigeration composite pipe, a refrigeration chamber, a refrigeration cooling chamber, a freezing chamber and a freezing cooling chamber are defined in the refrigerator body, a refrigeration evaporator and a freezing evaporator are respectively arranged in the refrigeration cooling chamber and the freezing cooling chamber, and the refrigeration composite pipe comprises a refrigeration main pipe section and a refrigeration bypass pipe section. The refrigeration main pipe section extends out of the box body from the refrigeration cooling chamber, the refrigeration bypass pipe section extends out of the box body from a joint part on the refrigeration main pipe section, and a first fan is arranged in the refrigeration bypass pipe section. The control method comprises the steps that in the operation process of the refrigerator, whether a refrigeration evaporator is in a refrigeration state in which a refrigerant flows or not is judged; and if the refrigeration evaporator is in the non-refrigeration state except the refrigeration state, the first fan is controlled to rotate reversely, so that ambient air outside the box body flows to the refrigeration cooling chamber through the refrigeration main pipe section and the refrigeration bypass pipe section, and the ambient air is used for defrosting the refrigeration evaporator.

Description

technical field [0001] The invention relates to refrigeration and freezing technology, in particular to a control method of a dual-system refrigerator. Background technique [0002] For dual-system refrigerators, the refrigerating evaporator and freezing evaporator used to provide cooling capacity for the refrigerating chamber and freezing chamber respectively are independent of each other, and the defrosting of the refrigerating evaporator and freezing evaporator are also independent of each other, all using one The defrosting heater is used for defrosting, and the defrosting efficiency is limited to a certain extent, and the energy consumption of the defrosting heater is also relatively high. Contents of the invention [0003] An object of the present invention is to overcome at least one defect of the prior art, and provide a method for controlling a dual-system refrigerator with high defrosting efficiency and low energy consumption. [0004] A further object of the pr...
