【摘 要】Operational Feasibility Analysis of the Improved Ein-stein Refrigeration Cycle System
In the paper,the principle of single pressure absorption-type Einstein refrigeration cycle was introduced. Three iraproved Einstein refrigeration systems ( Ⅰ,Ⅱ,Ⅲ) built in our previous work were compared. The thermodynamic roodels of the three systems were established using mass and energy conservation law. Then their performances were analyzed. The results show that system Ⅱ has the highest COP (0.255 1 ) under the same working conditions. Changing the working conditions cannot very effectively improve the system COP. But the system refrigeration performance can be effectively improved by reasonably matching system components, optimizing pipeline resistance, using heat recov- ery system and efficient bubble pump, and then choosing the best generation temperature. This study is expected to provide important guidance for Einstein refrigeration cycle system performance optimization and industrial applica- tions. Key words : Einstein cycle, single pressure absorption-type refrigeration, improvement, feasibility analysis
