摘　　要：针对舰船远航时某新型海水淡化装置性能随海水盐度等因素变化而改变的问题,分析了该型海水淡化装置主要影响因素,并对其造水量进行了热力校核计算.实例计算结果表明,某航行海区较设计海区排污系数相对增大近25倍,造水量由原来的2 042 kg/h下降到1 847 kg/h,下降了9.55%.In view of the performance of a new-type sea water desalination unit in a ship varying with the salinity of the seawater when the ship is at sea, this paper analyzes the main factors influencing the performance of the main sea water desalination unit and gives the thermodynamic check calculation of the water production capacity. The results of calculation by using the example show that the blowdown coefficient ε of one navigation sea area relatively increases about 25 times over that of the design sea area and the water production capacity falls down from 2 042 kg/h to 1 847 kg/h, decreases about 9.55%.
