摘　　要：针对某双燃料船舶燃气供应系统项目,提出了采用天然气汽化加热器载热剂乙二醇传递的冷能再利用,并设计了船舶空调系统节能方案。基于PROII过程,对天然气汽化系统原理设计进行了热力学分析,依据超大型油轮双燃料主机液化天然气供气系统的燃料供液量,计算出可利用冷能的总量为2 000 kW。优化后的空调系统可以满足船舶空调房间的冷负荷。通过定量的经济性分析,该系统可降低船舶空调系统能耗,实现节能减排。In a dual fuel ship gas supply system project,we put forward with natural gas evaporation heater heating agent glycol which can transfer cold recycling,and designed a set of air conditioning system solutions,based on the PROII thermodynamics.Analysis was carried out on the principle of system design,according to the VLCC combined dual fuel host LNG supply system for fluid volume,amount of cold energy can be used is 2000 kW.It is fully fit the airconditioning cooling load.Through economic analysis and calculation,the comprehensive energy efficiency of ships can be reduced to meet the requirements of energy conservation and emission reduction.
