چکیده

در این مقاله، تاثیر فشار پایین بر خواص ترمو-فیزیکی جریان، بارهای حرارتی و عملکرد سیستم تبرید جذبی آب-آمونیاک تحت دو حالت مختلف بررسی می‌گردد. این حالات عبارتند از بررسی تحت یک دمای ثابت ژنراتور و بررسی تحت دماهای بهینه تعیین شده متناسب با تغییرات فشار پایین. همچنین تغییرات کیفیت اشباع مبرد ورودی-خروجی اواپراتور و ورودی ابزوربر بر حسب فشار پایین مورد توجه قرار می‌گیرد و مقدار بهینه فشار پایین با تمرکز بر حالت مبرد در نقاط مذکور و عملکرد سیستم تعیین می‌گردد. نتایج نشان می‌دهد که فشار پایین بهینه بایستی با تمرکز بر کیفیت مبرد در نقاط مذکور تعیین گردد.
