    摘要： A combination refrigerator-freezer with dividing air-impermeable air-to-air heat exchanger is a system for cooling a refrigerator compartment and a freezer compartment utilizing a single cooling system and without mixing or exchanging air between the refrigerator compartment and the freezer compartment. Cold air is generated by the cooling system and circulated into the freezer compartment and into a freezer airflow compartment where the cold air cools an air-to-air heat exchanger. Warmer air circulating through a refrigerator airflow compartment positioned opposite to the freezer airflow compartment is cooled by the air-to-air heat exchanger and is in turn able to cool the refrigerator compartment. A control unit is utilized to control the temperatures within the refrigerator compartment and the cooling compartment and to ensure that the system is not active while defrosting is in progress. A first defroster and a second defroster are utilized to prevent key components from icing up.
