Abstract
A temperature controlled compartment apparatus in the form of a kitchen drawer mounted in an interior compartment that is heated or cooled by one or more thermoelectric heat pump modules in a housing surrounding the drawer. A fan circulates air from the drawer past each thermoelectric heat pump module for either heating or cooling the air for the drawer and another fan or fans circulates external air past each thermoelectric heat pump module for cooling or heating, respectively, that external air. Heating or cooling is selected by selecting the polarity of the DC electric source provided to each thermoelectric heat pump module.
