A cold water tank includes a tank body, a cover part connected to the tank body to cover an open top of the tank body, and a cooling unit disposed in the tank body to cool water stored inside the tank body so as to make cold water. The cover part is configured to have an air layer formed therein, thereby minimizing or preventing the occurrence of condensation.

A reversible flow heat exchange system includes a heat exchanger system that includes a canister configured to receive a first fluid from a machine and a heat exchanger disposed within the canister. The reversible flow heat exchange system also includes a cooling system coupled to the heat exchanger and configured to circulate a second fluid between the heat exchanger system and the cooling system and a reversing valve coupled to the heat exchanger and configured to selectively direct a flow of the first fluid in a first direction through the canister and in a second direction through the canister that is opposite the first direction.

Disclosed are a cold-water generating tank for generating cold water by using the ice thermal storage method and a water cooler equipped with same. The disclosed cold-water generating tank may comprise: a tank body which houses, on the inside thereof, an ice storage liquid cooled by means of a cooling unit; a cooling tube provided on the inside of the tank body in order to cool the ice storage liquid housed inside the tank body; and a cold-water generating unit which has a heat exchange tube forming a flow pathway where inflowing water becomes cold water through heat exchange with the ice storage liquid, and has an extension member positioned on the outer circumferential surface of the heat exchange tube in order to widen the area of contact with the ice storage liquid.

A portable drink holder for a drinkable liquid having a first removable reservoir for storing the liquid at a first end of the holder, a second removable reservoir at a second end of the holder for receiving the liquid and a cooling cartridge having at least one passageway for selectively transporting liquid from the first reservoir to the second reservoir. The cooling cartridge includes a cooling medium so that the liquid transitions to a second temperature lower than the first temperature as it flows from the first reservoir to the second reservoir.

A beverage chiller assembly has a bottom vessel portion and a top portion comprising a plurality of extruded tubes arranged in an array. The bottom and top portions fit together to receive and expeditiously chill a beverage, such as an individual portion of hot coffee, to produce ice coffee, or a bottle of white wine, or a serving of another beverage. The tubes are pre-cooled and extend vertically down into the beverage or fluid volume, and are arranged and dimensioned to provide effective, fast and substantially uniform cooling of the intended beverage volume to a specified serving temperature. Embodiments quickly convert hot coffee to iced coffee, or chill white wine to a proper temperature for serving. Specific embodiments may attain a stable final temperature and also function as serving vessels at table.

Exemplary embodiments are generally directed to beverage chillers for chilling a hot beverage so that the hot beverage can be served as a chilled beverage in real time on demand fashion. The beverage chillers include a beverage collection section, a heat exchanger section, and a dispensing section fluidically connected relative to each other. The beverage collection section receives a beverage in a hot state. The heat exchanger section chills the beverage from the hot state to a predetermined chilled temperature. The dispensing section dispenses the beverage at or near the predetermined chilled temperature. Exemplary embodiments are also directed to methods and systems for chilling a hot beverage in real time on demand fashion.

A beverage-making apparatus includes a fermentation tank assembly including a fermentation tank having an opening formed therein and a fermentation tank cover configured to open and close the opening. The beverage-making apparatus also includes a refrigeration cycle apparatus including a compressor, a condenser, an expansion device, and an evaporator. The refrigeration cycle apparatus is configured to circulate a refrigerant therethrough and to control a temperature of the fermentation tank as the evaporator is disposed at the fermentation tank. The beverage-making apparatus further includes a heat insulating wall surrounding both the fermentation tank and the evaporator.

A reversible flow heat exchange system includes a heat exchanger system that includes a canister configured to receive a first fluid from a machine and a heat exchanger disposed within the canister. The reversible flow heat exchange system also includes a cooling system coupled to the heat exchanger and configured to circulate a second fluid between the heat exchanger system and the cooling system and a reversing valve coupled to the heat exchanger and configured to selectively direct a flow of the first fluid in a first direction through the canister and in a second direction through the canister that is opposite the first direction.

A post-mix beverage dispenser having all components within an insulated housing is provided. The beverage dispenser can include an insulated housing with interior compartments that contain all complementary for dispensing a beverage, a carbonated beverage, and ice. The interior compartments can contain a concentrate source, a concentrate pump, an ice bin, an ice dispensing mechanism, a refrigeration system, a diluent pump, and a carbonation system.

A cooling system for rapidly cooling a beverage comprises a cooling channel configured to convey a beverage from upstream to downstream and a nozzle. The cooling channel includes an inner peripheral surface and the nozzle sprays the beverage on the inner peripheral surface such that the beverage is conveyed by gravity along the inner peripheral surface. The beverage cools as the beverage is conveyed by gravity along the inner peripheral surface such that the beverage is cooled by condensation and convection. The nozzle is further configured to reduce the pressure of the beverage such that the beverage cools due to expansion and reduction of pressure. The cooling system can also include a cooling media circulation system, a cooling media refrigeration system, and a post-chill coil.
