Abstract
A beverage dispensing apparatus is characterized by a beverage dispenser and a refrigeration system for chilling beverage to be dispensed by the beverage dispenser. The refrigeration system has a compressor coupled to an evaporator for chilling the beverage, and a controller determines the amount of chilling that must be provided by the refrigeration system to chill the beverage and adjusts cut-in and cut-out beverage temperature set-points for the compressor accordingly. Advantageously, the cut-in and cut-out set-points are adjusted to beverage temperature values such that the chilling capacity of the refrigeration system is made to closely match to the amount of chilling required by the beverage, and also such that on/off cycles of the refrigeration system are decreased.
