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.

The disclosure relates to an open-loop cooling system installed on a refrigerated barge for removing heat from an external heat exchanger in communication with a closed-loop internal cooling system. The system includes an open loop with a pump drawing water from the environment and forcing the water across the outer surface of the heat exchanger to augment existing heat removal due to contact with and flow of water across the heat exchanger due to the motion of the barge. Water is forced across the side faces and inner faces of the cooler to increase hea...

1. A refrigerated inland waterway barge, comprising: an outer hull;a liquid water-based closed-loop cooling system disposed within the outer hull of the refrigerated inland waterway barge;a heat exchanger in fluid communication with the closed-loop cooling system, wherein the heat exchanger is disposed in a recessed section of the outer hull and outside of the outer hull of the refrigerated inland waterway barge with a gap between the outer hull and an inner face of the heat exchanger; andan open-loop cooling system in fluid communication with the heat exchanger, the open-loop cooling system comprising: a first piping line between an inlet in the outer hull and an outlet in the recessed section of the refrigerated inland waterway barge, wherein the outlet is positioned at least partially aligned with the gap; anda pump disposed along the first piping line. 2. The open-loop cooling system of claim 1, further comprising: a constriction segment disposed between the first piping line and the outlet. 3. The refrigerated barge of claim 1, wherein the recessed section includes forward, aft, port, starboard, and back walls, and wherein the outlet is disposed in the forward wall. 4. The open-loop cooling system of claim 1, further comprising: a second piping line bypassing the pump and disposed between the inlet and the outlet. 5. The open-loop cooling system of claim 4, further comprising: a valve on the first piping line;a valve on the second piping line; anda controller configured to actuate the valves on the first and second piping lines to switch a water flow in the first piping line ON/OFF. 6. The open-loop cooling system of claim 5, wherein the controller is configured to switch the water flow in the first piping line ON/OFF based on at least one of: a speed of the refrigerated barge, a temperature of a cargo stored on the refrigerated barge, and a temperature difference between a temperature of a fluid in the closed-loop cooling system and a temperature of water surrounding the outer hull. 7. The refrigerated barge 1, wherein the heat exchanger is a grid cooler. 8. A refrigerated inland waterway barge, comprising: an outer hull of the refrigerated inland waterway barge;an inner hull of the refrigerated inland waterway barge;a liquid water-based closed-loop cooling system disposed within the inner hull;a heat exchanger in fluid communication with the closed-loop cooling system and immersed in an ambient water environment, wherein the heat exchanger is disposed between the outer hull and the inner hull with a gap between the inner hull and an inner face of the heat exchanger; andan open-loop cooling system in fluid communication with the heat exchanger, the open-loop cooling system comprising: a first piping line between an inlet in the outer hull and an outlet in the outer hull positioned at least partially aligned with the gap; anda pump disposed along the piping,wherein the outer hull has a plurality of slits to allow the exit of water entering through the inlet. 9. The open-loop cooling system of claim 8, further comprising: a constriction segment disposed between the piping and the outlet. 10. The refrigerated barge of claim 8, wherein the recessed section includes forward, aft, port, starboard, and back walls, and wherein the outlet is disposed in the forward wall. 11. The open-loop cooling system of claim 8, further comprising: a second piping line bypassing the pump and disposed between the inlet and the outlet. 12. The open-loop cooling system of claim 11, further comprising: a valve on the first piping line;a valve on the second piping line; anda controller configured to actuate the valves on the first and second piping lines to switch a water flow in the first piping line ON/OFF. 13. The open-loop cooling system of claim 12, wherein the controller is configured to switch the water flow in the first piping line ON/OFF based on at least one of: a speed of the refrigerated barge, a temperature of a cargo stored on the refrigerated barge, and a temperature difference between a temperature of a fluid in the closed-loop cooling system and a temperature of water surrounding the outer hull. 14. The refrigerated barge 8, wherein the heat exchanger is a grid cooler. 15. A method of cooling a refrigerated inland waterway barge, the method comprising: supplying a flow of water from an ambient water environment to a side of a heat exchanger immersed in the ambient water environment and facing an inner hull of a refrigerated inland waterway barge, wherein the heat exchanger is in fluid communication with a liquid water-based closed-loop cooling system and disposed between the inner hull and an outer hull of the refrigerated inland waterway barge, wherein the heat exchanger is mounted with a gap between the inner hull and the heat exchanger to allow for the passage of water, wherein at least part of the flow of water is into the gap. 16. The method of claim 15, further comprising: constricting the flow of the water to increase a velocity of the water across the heat exchanger. 17. The method of claim 15, wherein supplying the water comprises: pumping the water. 18. The method of claim 15, wherein supplying the flow of water comprises: pumping the water; or, alternatively, allowing a natural flow of the water; andswitching between pumping the water and allowing the natural flow of water based on predetermined criteria. 19. The method of claim 18, wherein the switching comprises opening/closing a valve dedicated to pumping the water and closing/opening a valve dedicated to allowing the natural flow of the water. 20. The method of claim 15, wherein the heat exchanger is a grid cooler. 21. A method of cooling a refrigerated inland waterway barge, the method comprising: supplying a flow of water from an ambient water environment to an inner side of a heat exchanger in fluid communication with a liquid water-based closed-loop cooling system and disposed in a recessed section of an outer hull and outside of the outer hull of the refrigerated inland waterway barge, wherein the heat exchanger is mounted with a gap between the recessed section and the heat exchanger to allow for the passage of water, wherein at least part of the flow of water is into the gap. 22. The method of claim 21, further comprising: constricting the flow of the water to increase a velocity of the water across the heat exchanger. 23. The method of claim 21, wherein supplying the water comprises: pumping the water. 24. The method of claim 21, wherein supplying the flow of water comprises: pumping the water; or, alternatively, allowing a natural flow of the water; andswitching between pumping the water and allowing the natural flow of water based on predetermined criteria. 25. The method of claim 24, wherein the switching comprises opening/closing a valve dedicated to pumping the water and closing/opening a valve dedicated to allowing the natural flow of the water. 26. The method of claim 21, wherein the heat exchanger is a grid cooler.
