アルミ製プレート式熱交換器におけるアンモニア沸騰熱伝達特性

抄録

The ammonia boiling heat transfer characteristics on the plate evaporator installing proposed aluminum plates for Ocean Thermal Energy Conversion were clarified. The proposed two aluminum plates have heat transfer surface which are anodic acid coated in chevron shape, and the chevron angles are 45° and 60°. For comparison, the titanium plates is also used. In this study, the measurement of the overall and the ammonia boiling heat transfer ammonia under the ammonia and hot water heat transferring on the plate evaporator are performed. As a result, the effect of heat transfer performance on the mass flux of the ammonia and hot water, and hot water temperature are clarified.
