Abstract: A method and apparatus for dispensing large numbers of wine servings at uniform temperatures is disclosed which includes a source (14) of wine at room temperature connected to a refrigeration unit (16). A wine dispensing valve (18) is connected to the refrigeration unit (16) for dispensing wine. A wine metering and mixing valve (A) is connected between a delivery line (20) and a dispensing line (22) to bypass a metered amount of room temperature wine from the delivery line to the dispensing line and thus raise the temperature of the wine to a desired wine serving temperature prior to serving.

Abstract: An apparatus for charging a refrigeration system with a predetermined amount of refrigerant by weight. The apparatus includes a cylinder which is mounted on top of a strain gauge scale that is first filled from a source of refrigrant and then automatically discharged to fill a refrigeration system with a predetermined amount of refrigerant. The system includes solenoid operated valves which are automatically operated for loading the cylinder and charging the refrigeration system. A vacuum pump is also included in the circuit for placing the refrigeration system under a predetermined vacuum prior to the charging operation.

Abstract: A refrigeration system for cooling a beverage as the beverage is drawn from a container filled with water which has an evaporator coil carried adjacent the wall thereof which extends from adjacent the top of the container to the bottom of the container. When a refrigerant is circulated through the evaporator coil, an ice bank is built up on the inner wall of the container. A beverage dispensing coil is centrally located with the container and is connected between a faucet and the container from which the beverage is to be drawn. A helical support coil extends from adjacent the top of the container to the bottom and encircles the beverage dispensing coil. A temperature sensor is threaded inside the helical copper support coil so that any time the ice bank builds up closely adjacent thereto, it will turn off the compressor. A motor driven power paddle is used for circulating the water within the container.
