船用转轮除湿空调系统方案的探讨

Study on the Scheme of a Marine Rotary Desiccant Air-conditioning System

探讨转轮除湿空调系统在船舶上应用的可行性。在分析干燥剂再生温度和除湿效果的基础上,根据船舶余热的品质和船舶空调的特点,构建了一个船用除湿空调系统。该系统采用单个转轮两级除湿的方案,利用船舶余热作为干燥剂的再生热源,采用海水冷却和压缩式制冷机组冷却相结合的冷却方式,以保证送风温度的稳定。根据所确定的系统方案,建立起船用单个转轮两级除湿空调系统的实验台,用于研究模拟海洋环境下该系统的性能。

A system of one rotor two-stage marine desiccant air-conditioning was constructed,with the analysis of the desiccant regeneration temperature and dehumidification effect,and combined with the quality of marine waste heat and the characteristic of marine air-conditioning system.In the system,the wheel was divided into four parts in turn： dehumidification area 1,regeneration area 1,dehumidification area 2 and regeneration area 2,the central angle for each dehumidification area is 135° and for each regeneration area is 45°.The marine rotary desiccant air-conditioning system can make effective use of marine waste heat as driving heat source.Process air is cooled by seawater and compression type refrigerating unit,which can save operation energy consumption and ensure stability of supply air state.An experimental platform of one rotor two-stage marine rotary desiccant air-conditioning system was established according to the proposed system scheme.
