Multi-compartment refrigeration system

A refrigerator comprising:

• a cabinet having at least a first, a second, and a third compartment of which at least two are maintained at different temperatures;
• a cooling system having
• a single evaporator for cooling the air in the refrigerator;
• a compressor fluidly interconnected with said evaporator for moving refrigerant through said evaporator;
• a latching relay for selectively connecting said compressor to a power supply;
• a first switch for selectively connecting said first fan to a power supply;
• a second switch for selectively connecting said second fan to a power supply;
• and
• control means for receiving user input and operating said latching relay to energize or de-energize said compressor and for firing said first and second switches such that said first and second fans can be selectively operated at said first and second speeds;
• a duct system fluidly connecting the first, second, and third compartments;
• and
• an air flow controller having a blower for forcing air over the evaporator and the air flow controller directing the forced air through the duct system to the first, second, and third compartments as needed to maintain their respective temperatures.

• an air flow controller having a blower for forcing air over the evaporator and the air flow controller directing the forced air through the duct system to the first, second, and third compartments as needed to maintain their respective temperatures;
• said air flow controller comprises a single proportional baffle to proportionally direct the cooled air from the evaporator, through the duct system, to the compartments as needed.

• said air flow controller comprising a proportional baffle to proportionally direct the cooled air from the evaporator, through the duct system to the compartments as needed;
• and
• said blower is positioned at the outflow of the forced air and within the duct system, and the proportional baffle comprises a movable air dam movably mounted to the blower, whereby moving the air dam proportionally splits the forced air outflow where it is directed to the first, second, and third compartments through the duct system.

A refrigerator comprising:

• a cabinet having at least a first, a second, and a third compartment of which at least two are maintained at different temperatures;
• a cooling system having a single evaporator for cooling the air in the refrigerator and said evaporator is operable at a plurality of different pressures;
• a duct system fluidly connecting the first second, and third compartments;
• and
• an air flow controller having a blower for forcing air over the evaporator and the air flow controller directing the forced air through the duct system to the first, second, and third compartments as needed to maintain their respective temperatures.

A refrigerator, comprising:

• at least three separately cooled compartments;
• an evaporator chamber having an outlet;
• an evaporator disposed in said evaporator chamber;
• means for moving air over said evaporator and through said outlet;
• a single baffle means disposed at said outlet for selectively directing independent air flow to said at least three separately cooled compartments .
