分析比较了吸收 喷射复合制冷循环系统和双效吸收式制冷循环系统在热力性能和流程方面的差异 ,提出了两系统的热经济学模型 ,并分别对余热型和直燃型冷水机组进行了计算 .通过计算结果的比较 ,指出余热型三压吸收 喷射复合制冷系统比双效吸收式制冷系统经济 .当采用直燃型冷水机组时 (相对价格比 β >β1) ,发现两系统在热经济性方面具有可比性
The difference of thermal performance and flow between absorption and injection combined refrigeration cycle system and double-effect absorption refrigeration cycle system is analyzed and compared. The thermal economics model of two systems is proposed and the heat-recovery and direct-fired chillers are respectively calculated By comparing the calculation results, it is pointed out that the waste heat-type three-pressure absorption combined injection refrigeration system is more economical than the double-effect absorption refrigeration system.When the direct combustion type chiller is used (relative price ratio β> β1) Comparable
