Marine Liquid-Desiccant Evaporative-cooling Air-conditioning System and Its Performance Analysis

分析了海洋环境、船舶运行的特点,从能量利用的角度出发,构建一种新型的船用溶液除湿蒸发冷却空调系统,并根据ISO7547标准的设计参数,对该系统在不同新风比下的性能进行理论分析.分析结果表明,该系统能够满足送风要求,且当新风比大于40%时,与传统的船用一次回风空调系统相比,节能潜力大于60%.该系统能够充分利用船舶空调湿负荷大、船舶余热多以及海水冷源充足的特点,实现船舶空调的节能.

A novel marine liquid-desiccant evaporative-cooling air-conditioning （A/C） system was con- strutted according to the characteristics of marine environment and shipping from energy utilization point of view. The performance of the marine liquid-desiccant evaporative-cooling A/C system was theoretical analyzed with different fresh air ratios under design conditions of the standard IS07547. It was found that the liquid- desiccant evaporative-cooling A/C system can satisfy the requirements of supply air and compared with the tra- ditional marine A/C system with primary return air the liquid-desiccant evaporative-cooling A/C system can save more than 60% energy consumption when fresh air ratio was larger than 40%. Therefore it can be con- eluded that the marine liquid-desiccant evaporative-cooling A/C system can take full advantages of large latent load of marine air-conditioning, abundant residual heat of ship and unlimited seawater to realize significant energy-saving.
