概要:
抄録:
Experimental study is carried out to measure heat transfer coefficient of ammonia-water mixture on a horizontal heated surface, which is one of the nonazeotropic binary mixtures. The nonazeotropic binary mixtures have variable boiling and dew points, depending on the mixture components and concentrations. It is expected to have a higher coefficient of performance as a result of decreasing the thermodynamically irreversible loss, when there is a relevant concentration. Therefore, ammonia-water mixture is used as working fluid in small temperature difference power generation cycles and absorption refrigeration cycles. However, few experiments were carried out in the world for measuring heat transfer coefficient for ammonia-water mixture. Heat transfer coefficient was measured and compared with existing correlations prediction and a revised correlation can be proposed.
