摘要:: 为在船舶中应用余热吸附式的研究成果，选择“SITC TAISHAN”号散货船，通过船舶主机在额定工况下的能量衡算，应用当前氨-活性炭吸附式制冷系统COP的经验值，分析了该轮中央空调系统和伙食冷库采用废气锅炉蒸汽驱动的氨-活性炭吸附式制冷系统的可行性.并且，根据氨在SAC-02活性炭上的吸附平衡数据和活性炭吸附床的循环吸附特性，结合“SITC TAISHAN”轮空调机间的结构特点，规划了由废气锅炉蒸汽驱动的9床循环氨-活性炭吸附制冷系统方案，并对系统的关键部件及运行控制方案设计提出了相应措施.该研究将有助于推进船舶余热吸附式制冷技术的应用

Abstract:: Analysis of the feasibility of applying adsorption refrigeration on board ships was carried out in this paper.A bulk carrier-M/V “SITC TAISHAN” was selected and analysis of energy balance of the main engine of the ship was carried out at its nominal working condition.Based on the coefficient of performance (COP) currently obtained in activated carbon-ammonia adsorption refrigeration system,the feasibility of applying the adsorption refrigeration on board the ship was evaluated by the amount of waste heat contained within the exhaust gas.Secondly,activated carbon SAC-02 was selected and the adsorption isotherms of ammonia on the activated carbon were volumetrically measured and used to design the adsorption towers for ammonia-activated carbon adsorption refrigeration system.A new kind of adsorbent bed was developed,and an ammonia-activated carbon adsorption refrigeration system which was powered by the waste heat from the steam of the exhaust gas was finally designed in terms of the practical structure of the ship.The research carried out in this work is beneficial to the practical application of adsorption refrigeration system on a ship.
