ABSTRACT:
An improvement in open front refrigerated cabinets for food product storage and displaying in which transparent barrier doors and an air defrost system are provided for improving the energy efficiency. Barrier doors and an air defrost system can be retrofitted onto an open front refrigerated display case in order to permit operation of the cabinet with lower energy consumption. The air defrost system selectively creates a gap between the barrier doors and the associated access opening in order to provide for through-flow of ambient air during a defrost cycle. Open front cabinets having either single or multiple circulated air bands can be improved with this invention. The method of retrofitting such cabinets and the method of operations thereof is also included.
