A refrigerator includes a water tank which stores water, a carbon dioxide cylinder which stores carbon dioxide, a dispenser module which accommodates an external container and supplies the carbon dioxide and the water to the external container, and a controller which supplies the water to the external container and supplies the carbon dioxide to the external container when supplying the water is completed.

A system and method is provided for electronically adjusting the pressure in a beverage container during regular use. The system includes a connector attachable to a tapping connector of the beverage container; a gas pump operably connected to the connector for supplying pressurized gas into the beverage container through the tapping connector; a pressure sensor operably connected to the beverage container for outputting a pressure signal corresponding to an internal pressure within the beverage container; a power supply; and a controller adapted to control the gas pump based on the internal pressure and a set point pressure to maintain the internal pressure at the set point pressure.

Disclosed are various embodiments for dispensing and tracking beverages. An identifier associated with a user can be read by an identification device. Beverage availability information for the user can be determined. The beverage availability information can specify categories of beverages that the user is authorized to dispense. Valves can be selected that correspond to the authorized beverage categories. The valves can be enabled to allow the user to dispense beverages from the authorized beverage categories. The quantity of beverages dispensed can be tracked.

Disclosed is a beverage dispensing cooler. The beverage dispensing cooler includes a first lid, a second lid, a body, an axle, a handle, multiple hoses and at least one sensor. The body includes a chamber, a panel, a base valve, a wall drain, a primary hose, a flow control unit, a power unit and a dispenser gun. The chamber includes multiple cylinders, multiple pressure compartments and a basin configured to collect water from condensation and melted ice. The axle further includes multiple wheels, a rod and multiple bearings connected to the rod and to the multiple wheels. The handle is configured to facilitate engagement of the beverage dispensing cooler with a hand of a user. Further, the beverage dispensing cooler may include at least one sensor configured to generate at least one sensor data corresponding to at least one variable.

Examples disclosed herein relate to conduits, devices, systems and methods, which may include a dispensing device including a valve configured to interact with an inlet stream, the inlet stream having a first pressure, the valve having an outlet area with an outlet stream, the outlet stream having a second pressure; and a solenoid configured to interact with the outlet stream.

A system or method for carbonating a liquid includes receiving, in a sealed container of a carbonator of a drink dispenser system, a predetermined amount of liquid, identifying a predetermined carbonation level associated with a flavoring material, and setting a target pressure of the sealed container based on the predetermined carbonation level. The target pressure is selected from a plurality of different target pressures. The system or method also can include releasing pressurized carbon dioxide from a carbon dioxide source into the sealed container holding the predetermined amount of the liquid therein until an internal pressure of the sealed container is substantially equal to the target pressure. The system or method can also include dispensing, into a drink container, the flavoring material and the liquid from the sealed container of the carbonator.

A dispenser system for providing variable carbonation can include a carbonated water source in communication with a carbonated water valve for controlling flow of carbonated water through the dispenser system; a still water source in communication with a still water valve for controlling flow of still water through the dispenser system; a nozzle in fluid communication with the carbonated water source and still water source; a processing device adapted to modulate the carbonated water and still water valves within a modulate cycle to achieve a ratio of carbonated to non-carbonated water; and a pour mechanism adapted to provide an input to the processing device to dispense the beverage.

Examples disclosed herein relate to conduits, devices, systems and methods, which may include a dispensing device including a valve configured to interact with an inlet stream, the inlet stream having a first pressure, the valve having an outlet area with an outlet stream, the outlet stream having a second pressure; and a solenoid configured to interact with the outlet stream.

A dispensing apparatus is described having a beverage source, containing a carbonated beverage liquid, and a dispensing tap. The dispensing apparatus includes a dispense tube disposing the beverage source in fluid communication with the dispensing tap and an infusion chamber arranged in connection with the dispense tube and configured to infuse an infusing ingredient with the carbonated beverage liquid. The dispensing apparatus includes a sensing unit configured to determine a level of carbon-dioxide in the liquid downstream of the infusion chamber. The dispensing apparatus includes a carbon-dioxide source coupled to the dispense tube via a valve. The dispensing apparatus further includes a control unit configured to operate the valve to allow flow of carbon-dioxide gas based on the determined level of carbon-dioxide in the carbonated beverage liquid, so as to bring the level of carbon-dioxide to a pre-defined level.

A beverage dispenser includes a gas infusion device that receives a base fluid and a gas and dispenses a gas infused liquid, a ratio pump that receives the gas infused liquid and a concentrate from a concentrate source and dispenses a predetermined ratio of the gas infused liquid and the concentrate, and a mixing chamber that mixes the predetermined ratio of the gas infused liquid and the concentrate to form a reconstituted beverage. An insulated enclosure has an interior space in which the ratio pump and the mixing chamber are positioned. A cooling heat exchanger is positioned in the insulated enclosure, and a first refrigeration system circulates a cooling media through the cooling heat exchanger to thereby cool the interior space to a suitable temperature such that the gas infused liquid and the concentrate dispensed from the ratio pump and the mixing chamber are cooled to the suitable temperature.
