摘　　要：基于将吸收器中溴化锂溶液的传热与传质过程相互分离的预冷却绝热吸收的溴化锂吸收式制冷循环,建立预冷却绝热吸收过程的热力学模型,对溴化锂溶液采用预冷却双效并联循环进行吸收过程的热力计算,并与传统双效并联循环进行比较,分析了预冷却器特性参数对预冷却绝热吸收过程及溴化锂吸收式制冷机组性能的影响及吸收器运行参数对预冷却绝热吸收过程的影响。The LiBr absorption refrigeration cycle of using pre-cooling adiabatic absorption based on the separating of heat transfer and quality transfer process of LiBr liquid in the absorption vessel were introduced. The thermodynamic model of pre-cooling adiabatic absorption process is found. The absorption process of LiBr liquid using pre-cooling double-effect parllel cycle is calculated and compared with convention double-effect parallel cycle. The affect of pro-cooler characteristic parameter on pre-cooling adiabatic absorption process and LiBr absorption refrigeration system performance is analyzed. The affect of running parameter of.absorption vessel on pre-cooling adiabatic absorption process is analyzed too.
