Abstract

A self-contained beverage chilling apparatus including a refrigerant cooling system comprising a refrigerant reservoir in a fluid communication with a cold plate, a refrigerator accumulator, a compressor and a refrigerant condenser mounted within a housing unit. The housing unit further included beverage inlet means in fluid communication with the cooling system cold plate, and beverage dispenser means in fluid communication with the cold plate wherein the beverage to be dispensed is chilled to a desired temperature as it passes through the cold plate to the beverage dispensing means.

1 . A beverage dispensing cooling system for dispensing chilled beverages comprising:
 a refrigerant condenser;   a cold plate;   a reservoir;   an accumulator;   a compressor; and   a defrost valve positioned within a bypass line positioned between the compressor and the cold plate, wherein said cooling system is filled with a critical charge of refrigerant and further wherein said cooling system operates with the refrigerant circulating through the system and wherein said defrost valve is opened at a predetermined pressure to allow refrigerant from the compressor to flow to and thaw the cold plate; and, a pressure regulator to control the pressure of the refrigerant as it exits the cold plate.   
     
     
         2 . The beverage dispensing cooling system of claim  5  further including means for controlling said pressure regulator and said defrost valve. 
     
     
         3 . A beverage dispensing cooling system for dispensing chilled beverages comprising:
 a refrigerant condenser;   a cold plate;   an accumulator;   a compressor;   a reservoir; and   a pressure control unit controlling refrigerant flow.
