摘　　要：为了解决低硫油的粘度与现有的船用柴油差异较大的问题,以4900t沥青船为研究对象,设计一种制冷剂直接与低硫油换热的冷却系统。该系统通过制冷剂直接与低硫油换热,使低硫油的运动粘度增加到2mm^2/s以上,满足现有船用柴油机供油系统的要求。实船运行表明:系统设计合理,性能稳定。In order to solve the problem that the viscosity of low-sulfur oil is different from the existing marine diesel,the 4900t asphalt carrier is taken as the research object,and a cooling system in which the refrigerant directly exchanges heat with low-sulfur oil is designed.The system directly exchanges heat with low sulfur oil through the refrigerant,so that the kinematic viscosity of the low sulfur oil is increased to(2 cSt)or more,which satisfies the existing marine diesel engine oil supply system.The actual ship operation shows that the system design is reasonable and the performance is stable.
