船用溶液除湿蒸发冷却新空调系统

摘要

构建了一种新型的利用船舶余热的船用溶液除湿蒸发冷却空调系统.根据实船的设计参数对该系统的节能效果进行研究分析,计算结果表明,与传统的一次回风船用空调系统比较,溶液除湿蒸发冷却空调系统在船舶上应用的节能效果可达51.8％.溶液除湿蒸发冷却空调系统应用在船舶上可采用船舶余热驱动处理船舶空调的湿负荷,充分适应船舶空调夏季工况湿负荷大的特点；同时,利用充足的海水冷源和节能环保的蒸发冷却技术对空气进行热、湿调节,从而获取良好的室内空气质量,实现显著节能.%A new type of marine liquid-desiccant evaporative cooling air-conditioning system utilizing ship's residual heat is constructed and its energy-saving effectiveness is analyzed according to the design parameters of a ship installation. It is indicated by calculation that this marine liquid-desiccant evaporative cooling air-conditioning system can reduce energy consumption by 51. 8% , compared with the ordinary marine air-conditioning system with primary return air. The marine liquid-desiccant evaporative cooling air-conditioning system is suitable for the large latent load condition of marine air-conditioning in summer season. This system also can fully utilize abundant sea water as cooling source and energy saving environment-friendly evaporative cooling technology for adjusting heat and humidity of the air to achieve a good indoor air quality while saving a large amount of energy.
