摘要： 介绍了天津石化蒸汽双效吸收式制冷站的设计概况。针对不同季节制冷负荷的差异，采用不同的制冷方式。冷冻水系统采用闭式循环，蒸汽系统设置了减温减压装置。对凝结水回收器进行了改进，使之同时满足凝结水回收和减温水供给的需要。试运行期间，出现了水泵电机过载的问题，分析为实际工作状态点偏离设计状态点所至，比较了3种不同处理方案，即采用增大局部阻力、变频和叶轮切削后增加局部阻力的方法加以修正。另外还出现蒸汽关断阀不能正常动作的情况，原因是阀门执行机构工作特性与制冷机工作原理不匹配，更换执行装置后动作正常。合理应用蒸汽双

Abstract: A presentation is given on the design of a lithium bromide absorption refrigeration plant in Tianjin Petrol-chemical Company. As the cooling load differs greatly between seasons, two methods of refrigerating for each season are introduced. Close circulation in chilled water system is used. Device for reducing the temperature and pressure of the steam system is installed. By improving the equipment for condensation water recycling, it is made providing both condensation water recycling and water distributing for reducing temperature of steam. During test run, overload happened in the motor of the circulating pump, the reason for that is the running state point departure with the design state point, comparing the three ways of tackling the problem: (1) increase partial resistance, (2) frequency conversion, (3) impeller cutting, then adopted the former for regulating. Also, the valve for shut off the steam in emergency did not act properly, owing to the property of the executing machine did not match with the working principle of the chiller, replaced the executing machine and it run normally. Using lithium bromide absorption refrigerating properly may optimize the  synthetical efficiency for energy utilization.
