| Outline of Final Research Achievements |
This study was aimed for the development of the new heat exchanger materials of a seawater water conversion device expected as one of the compound use of the ocean thermal energy conversion that the experiment in the true sea area was started in future. In the study period of three years, I manufactured new proposed test plates made by aluminum alloy and installed into a plate-type heat exchanger and performed the "tolerance evaluation against seawater and ammonia", “heat transfer performance evaluation using seawater and ammonia as a working fluid” and “heat transfer performance evaluation as a condenser of the seawater desalination system”. As a result, it was found that the proposed plate don’t observe the occurrence of the corrosion under the seawater and ammonia environment, then it can use enough under these condition. In addition, the plate show the enough heat transfer performance as a condenser of seawater desalination system.
