연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A beverage dispensing apparatus which includes a tank, a liquid inlet and a fluid dispensing system which includes a dispensing fluid conduit having a helical portion at least substantially vertically oriented within the interior volume of the tank. The beverage dispensing apparatus also includes a fluid circulating system that includes at least one fluid circulation conduit having an inlet portion positioned proximate the bottom portion of the tank and at least one outlet. A fluid cycling device is also included in the beverage dispensing apparatus and is configured to move fluid from the bottom portion of the tank to the fluid circulation conduit. The at least one outlet is configured to produce a fluid flow tangential to the orientation of the dispensing fluid conduit configuration. Evaporator coils extend around a perimeter of the tank's exterior sidewall surface and are configured to chill the fluid within the tank.

The beverage dispensing apparatus of claim 1, further comprising at least one fin insert disposed about an inside perimeter of the tank and extending from the at least one upwardly extending sidewall into the interior volume of the tank and extending along at least substantially all of the perimeter sidewall. 3. The beverage dispensing apparatus of claim 1, wherein the dispensing fluid conduit extends from proximate the bottom portion of the tank to about the top surface of the tank and the helical portion is a nonaligned helical portion. 4. The beverage dispensing apparatus of claim 2, further comprising a fluid moving device configured to move fluid within the tank into the inlet of the dispensing fluid conduit and out of the outlet and wherein the at least one fin insert is a single piece fin and includes an inner surface having a plurality of protrusions. 5. The beverage dispensing apparatus of claim 1, wherein the outlet of the fluid circulation conduit is positioned proximate the at least one perimeter sidewall extending upwards from the bottom surface and wherein the helical portion is biased towards the bottom portion of the tank. 6. The beverage dispensing apparatus of claim 1, wherein the fluid cycling device is a fluid pump and the evaporator comprises a series of evaporator coils extending around a perimeter of at least the top portion of the tank sidewall exterior surface. 7. The beverage dispensing apparatus of claim 1, wherein the fluid outlet of the fluid circulation conduit is disposed proximate and along at least a portion of the perimeter sidewall of the tank and wherein the interior volume of the tank is pressurized and configured such that the addition of fluid from the inlet of the fluid dispensing system forces chilled water to be dispensed from the outlet of the fluid dispensing conduit. 8. The beverage dispensing apparatus of claim 1, wherein the fluid outlet of the fluid circulation conduit is curvilinear and is configured to dispense the fluid onto and along an inside surface of the at least one perimeter sidewall forcing a spiraling fluid flow inside of the tank. 9. The beverage dispensing apparatus of claim 1, wherein the fluid is water and the evaporator comprises a series of evaporator coils that are positioned physically engaged to the tank sidewall exterior surface to chill the liquid in the tank. 10. A beverage dispensing apparatus comprising: a tank configured to receive and retain fluid and having a bottom surface, a top surface, and at least one upwardly extending perimeter sidewall extending upwards from the bottom surface defining an interior volume;a liquid inlet configured to deliver fluid from a fluid source to the interior volume of the tank;a fluid dispensing system comprising: a dispensing fluid conduit having a non-linear portion that extends from proximate the bottom of the tank to about the top surface of the tank and at least substantially vertically oriented within the interior volume of the tank and wherein the dispensing fluid conduit has an inlet proximate a bottom portion of the tank and an outlet positioned out of the interior volume of the tank wherein the inlet receives fluid from proximate the bottom of the tank, and wherein the fluid in the tank and the fluid received from the tank through the inlet are the same fluid; anda fluid circulating system comprising: at least one fluid circulation conduit having an inlet portion positioned proximate the bottom portion of the tank and at least one outlet positioned proximate the at least one perimeter sidewall of the tank;a fluid pump in fluid communication with the at least one fluid circulation conduit and configured to move fluid from the bottom portion of the tank to the fluid circulation conduit wherein the at least one outlet is configured to produce a fluid flow tangential to the orientation of the dispensing fluid conduit configuration;evaporator coils extending around a perimeter of the tank, in thermal communication with the tank and configured to chill the fluid within the tank; andat least one fin disposed about an inside perimeter of the tank. 11.
