Abstract
A drawer refrigeration unit provides two distinct zones of cooling in a single cabinet for two pull-out drawers. The refrigeration system includes an evaporator, a compressor and a condenser. The single evaporator system is aided by a damperless air circulation system to maintain the temperature zones at a temperature differential that is at least 10 degrees Fahrenheit. The present invention can thus be used as a combination refrigerator and freezer drawer unit using only one evaporator in a cross-ventilated cabinet.
