Refrigeration system for a beverage dispenser

摘要

In a post-mix beverage dispenser a heat conducting plate assembly couples the bottom wall of a carbonator tank to the side walls of beverage concentrate storage tanks for the bi-directional transfer of heat therebetween. The cold temperature of the carbonator tank including an ice bank therein chills the concentrate to help achieve a suitable serving temperature of a finished drink. The higher temperature of the concentrate helps warm the bottom area of the carbonator tank in the region of an outlet opening to preclude freezing of carbonated water in the outlet opening.
