Document Type and Number:
WIPO Patent Application WO/2021/034136
Kind Code:
A1
Abstract:
A method for controlling a refrigerating system using a non-azeotropic mixed refrigerant is provided. The refrigerating system may include a first evaporator configured to supply cold air to a freezer compartment located upstream and a second evaporator configured to supply cold air to a refrigerating compartment located downstream, based on a flow direction of the non-azeotropic mixed refrigerant. The method may include a first operation comprising operating a compressor, a freezer compartment fan to blow air to the first evaporator, and a refrigerating compartment fan to blow air to the second evaporator; a second operation comprising when the freezer compartment reaches a target temperature or the refrigerating compartment reaches a target temperature, continuously operating the compressor, and stopping the freezer compartment fan or the refrigerating compartment fan corresponding to one of the freezer compartment or the refrigerating compartment that reaches the target temperature; and a third operation comprising when both the freezer compartment and the refrigerating compartment reach the target temperatures, turning off both of the refrigerating compartment fan and the freezer compartment fan and stopping the compressor.
