A refrigeration appliance (100), comprising a housing (102), a first fluid pushing unit, a second fluid pushing unit and a controller (144). The housing (102) defines a refrigerating compartment, and the first fluid pushing unit and the second fluid pushing unit are installed to the housing (102) separately from each other. The controller (144) is in operable communication with the first fluid pushing unit and the second fluid pushing unit, and the controller (144) is configured to initiate a cooling operation, the cooling operation comprising: activating the first fluid pushing unit to create a first fluid flow; gradually increasing the speed stage of the first fluid pushing unit at a first predetermined ramp rate; activating the second fluid pushing unit to create a second fluid flow after activating the first fluid pushing unit; and gradually increasing the speed stage of the second fluid pushing unit.
