Airflow system and method for temperature control in integrated compartments in a refrigeration appliance

A method, comprising:

• providing a first air flow that is cooled by an evaporator directly positioned in a first compartment of a refrigeration appliance;
• controlling, via an airflow system, a temperature of a second compartment by the further substeps of:
• receiving, via a mainboard, a temperature setting for the second compartment;
• receiving, via the mainboard, a measured temperature detected by a sensor of the second compartment;
• controlling, by the mainboard, a flap of a damper positioned in a first supply duct based on a difference between the temperature setting and the measured temperature;
• directing, by the first supply duct coupled to the first compartment and the second compartment, the first air flow directly from the first compartment to the second compartment;
• directing, by a first return duct coupled to the first compartment and the second compartment, a second air flow from the second compartment to the evaporator;
• providing the temperature as a first temperature;
• controlling, by the airflow system, a second temperature of a third compartment by carrying out further steps of:
• directing, by a second supply duct coupled to the first compartment and the third compartment, a third air flow from the first compartment to the third compartment;
• and
• directing, by a second return duct coupled to the first compartment and the third compartment, a fourth air flow from the third compartment to the evaporator;
• providing the airflow system with at least one inner liner panel;
• the first supply duct, the second supply duct, the first return duct, and the second return duct being configured to be fastened to the at least one inner liner panel;
• and
• the at least one inner liner panel being configured for positioning on a first backside of the first compartment, a second backside of the second compartment, and a third backside of the third compartment.

An airflow system, comprising:

• an evaporator configured to decrease a temperature of air in a first compartment of a refrigeration appliance;
• a first supply duct configured for coupling to the first compartment and a second compartment of the refrigeration appliance and configured to direct a first air flow directly from the first compartment to the second compartment;
• a damper having a flap, said flap configured to be positioned based on a temperature setting of the second compartment;
• a second supply duct configured for coupling to the first compartment and a third compartment of the refrigeration appliance and configured to direct a second air flow from the first compartment to the third compartment;
• a first return duct configured for coupling to the first compartment and the second compartment and configured to direct a third air flow from the second compartment to said evaporator;
• a second return duct configured for coupling to the first compartment and the third compartment and configured to direct a fourth air flow from the third compartment to said evaporator;
• said first supply duct having a first opening formed therein;
• a housing having a first geometry extending into said first opening of said first supply duct, said housing configured to receive the air;
• and
• a fan configured for positioning in said housing and for distributing the first air flow through said first geometry to said damper positioned in said first opening of said first supply duct;
• said flap configured to be in an open position or a closed position;
• the open position corresponding to said damper directing the first air flow to the second compartment via said first supply duct, and the closed position corresponding to said damper obstructing said first supply duct;
• and
• said housing, said fan, and said evaporator being positioned directly in the first compartment.
