SYSTEM AND METHOD FOR TEMPERATURE CONTROL OF REFRIGERATOR WITH CONVERTIBLE COMPARTMENT

Abstract:

A method for controlling an operation of a refrigeration appliance comprises controlling a first cooling routine for a first compartment via a flow of a thermal exchange media to a first evaporator. The method further comprises controlling a heating routine in response to a setpoint temperature being greater than the temperature of the first compartment. The heating routine comprises activating a heating element and a fan in the first compartment over a first interval and deactivating the heating element and the fan over a second interval. The heating routine continues by activating the first interval and the second interval over alternating time periods. In response to the temperature of the first compartment being greater than or equal to a target temperature associated with the setpoint, the method may control the operation of the appliance by returning to the cooling routine.
