A refrigeration system having a container with at least two different temperature cooling zones separated by a divider. The divider has a wall and a partition spaced apart from each other. The partition has a heat transfer plate with a sheet with a heat transfer substance attached thereto. The refrigeration system may be cooled by a variable capacity compressor system having refrigeration and hot-gas defrost modes. The system is defrosted by circulation of gas therethrough. A controller may be engaged to and selectably operate the compressor system.

Refrigeration system and components thereof

An improved ice chest and cold plate apparatus for use in beverage dispensers. The ice chest and cold plate apparatus includes an ice storage container having an open top, a bottom, and four sidewalls. A cold plate heat exchanger is affixed to the outer surface of the bottom of the ice storage container with a thermally conductive adhesive. The cold plate includes a plurality of cooling circuits comprising tubular coils extending in a serpentine path and die-cast in aluminum to form an aluminum block. The improved ice chest and cold plate apparatus is simpler, less expensive and easier to manufacture than prior art ice chests with cold plates.
