摘　　要：淡水资源是本世纪重要但紧缺的战略资源,海水淡化是获取淡水的有效途径。本文提出了压缩式制冷循环的CO_2水合物海水淡化装置。实验选用浓度为25‰的海水,并在4组不同充注压力下进行。实验结果表明:节流装置的损失达到15 kJ/kg,其余部件损失为(3~8)kJ/kg。The fresh water resource is the most important but shortage strategic resource in this century,and the desalination is an efficient way to get fresh water.A new apparatus of CO2hydrate seawater desalination based on refrigeration cycle was proposed.The experiment was carried out under25‰seawater salinity and4kinds of filling pressure.The experimental result shows that,the exergy loss of the throttle device reaches up to about15kJ/kg,and the exergy losses of other components are within(3~8)kJ/kg.
