A cooling system for a beverage comprises an enclosure for housing a beverage container, a cold plate through which the beverage flows, and a refrigeration system that controllably cools the enclosure and the cold plate in a differential manner. In preferred embodiments, preference is given during normal operation to cooling the cold plate, and only cooling the enclosure when the cold plate is determined to be at or below a desired temperature. In some embodiments a special defrost cycle warms the cold plate while continuing to cool the enclosure. Controls can be mechanical, electronic or any combination of the two, and preferably utilizes information from both pressure and temperature sensors.

1. A cooling system for a beverage disposed in a container, comprising: an enclosure having a cavity sized and dimension to house the container; a cold plate; and a refrigeration system fluidly coupled to each of the cavity and the cold plate; and wherein the refrigeration system is configured to cool either the cavity or the cold plate from time to time, but not the cavity and the cold simultaneously. 2. The cooling system of claim 1, further comprising a circuit that cooperates with the refrigeration system to preferentially cool the cold plate relative to the cavity. 3. The cooling system of claim 1, wherein the refrigeration system is configured to simultaneously cool the cavity and the cold plate at other time. 4. The cooling system of claim 1, having a defrost mode in which a valve shunts a hot gas to the cold plate. 5. The cooling system of claim 4, wherein the refrigeration system includes a fan that cooperates with a condenser to cool a refrigerant, and further comprising a circuit configured to cause heating of the refrigerant by lowering a speed of the fan. 6. The cooling system of claim 4, further comprising a sensor configured to sense at least one of a pressure and a temperature of the hot gas, and a circuit that cooperates with the sensor to trigger opening of the valve. 7. The cooling system of claim 4, further comprising a sensor configured to sense at least one of a pressure and a temperature of the hot gas, and a circuit that cooperates with the sensor to trigger both opening and closing of the valve. 8. The cooling system of claim 4, further a circuit that uses a timer to at least partially control operation of the defrost mode. 9. The cooling system of claim 1, having a defrost mode that uses a resistance heater to provide heat to the cold plate. 10. The cooling system of claim 1, further comprising an electronic circuit configured to operate the cooling system in (a) a box mode in which the refrigeration system operates to cool the cavity, (b) a cold plate mode in which the refrigeration system operates to cool the cold plate, and (c) a cold plate defrost mode, in which the refrigeration system operates to defrost the cold plate. 11. The cooling system of claim 10, wherein the electronic circuit is further configured to operate the cooling system in (d) a box defrost mode, in which the refrigeration system operates to defrost the cavity. 12. The cooling system of claim 1, wherein the cold plate is physically coupled to the enclosure by a coupling other than a fluid line. 13. The cooling system of claim 1, wherein the cold plate is spaced apart from the enclosure by at least 0.1 meter. 14. The cooling system of claim 1, wherein the enclosure has a wall having an insulation R-value of at least 3. 15. The cooling system of claim 1, further comprising a door switch, and a circuit that cooperates with the door switch to turn off refrigeration to the cavity, but not to the cold plate. 16. The cooling system of claim 1, wherein the cavity is at least 0.03 M3. 17. The cooling system of claim 1, wherein the cavity is between 0.01 M3 and 0.02 M3, inclusive. 18. The cooling system of claim 1, further comprising a mechanical controller configured to operate the cooling system in (a) a box mode in which the refrigeration system operates to cool the cavity, (b) a cold plate mode in which the refrigeration system operates to cool the cold plate, and (c) a cold plate defrost mode, in which the refrigeration system operates to defrost the cold plate. 19. The cooling system of claim 18, wherein the mechanical controller is further configured to operate the cooling system in (d) a box defrost mode, in which the refrigeration system operates to defrost the cavity.
