Abstract
A vapor cycle refrigeration system includes a thermoelectric device (TED) as a sub-cooler to sub-cool liquid refrigerant exiting a condenser to increase cooling capacity of an evaporator and pull down temperature within a refrigerated compartment quickly. The TED sub-cooler is turned off after initial temperature pull down and is not operated during steady state operation for maintenance of the compartment temperature.
