[ 1 ] - بهینه‌سازی ترمواکونومیک و تحلیل اکسرژی چرخه‌ی تبرید تراکمی بخار
در کار حاضر روش ترمواکونومیک به‌منظور بهینه‌سازی چرخه‌ی تبرید تراکمی بخار مورد استفاده قرار گرفته است. میزان بار برودتی و دمای داخل و خارج، به‌عنوان قیدها لحاظ شده‌اند. در این تحلیل دو پارامتر بهینه‌سازی در نظر گرفته شده است. اولین پارامتر، اختلاف بین دمای چگالش و محیط خارج است که فشار چگالش را تعیین می‌کند. تعیین اختلاف بین دمای تبخیر و محیط داخل به عنوان دومین پارامتر، تعیین کننده‌ی فشار تبخ...
[ 2 ] - The Mathematical Method and Thermodynamic Approaches to Design Multi-Component Refrigeration used in Cryogenic Process Part II: Optimal Arrangement
A refrigeration cycle is a chain of various pieces of equipment including compressors, condensers, evaporators, and expansion devices each of which takes on a particular thermodynamic process duty in the cycle that eventually results in the production of the required refrigeration. The results of optimized mixed refrigerant cycles (MRCs) in Part I show that the configuration of MRC is an eff...
[ 3 ] - Optimal Synthesis of a Cascade Refrigeration System of LNG Through MINLP Model for Pure Refrigerant Cycles
 liquefied natural gas (LNG) is the most economical way of transporting natural gas (NG) over long distances. Liquefaction of NG by using vapor compression refrigeration system requires high operating and capital cost. Due to lack of systematic design methods for multistage refrigeration cycles, the conventional approaches of determining optimal cycle configuration are mostly based on trial-an...
[ 4 ] - Mathematical Method and Thermodynamic Approaches to Design Multi-Component Refrigeration Used in Cryogenic Process Part I: Optimal Operating Conditions
Abstract: Minimizing the work consumed in refrigeration system is the most effective measure to reduce the cost of products in sub-ambient chemical processes. The introduction of mixed working fluids into refrigeration system in place of pure working fluids is a recent advancement applied in the field. Due to the lack of systematic design method for Mixed Refrigerant Cycle (MRC), conventional a...
[ 5 ] - Optimal Synthesis of Cascade Refrigeration in Liquefied Natural Gas Cycles by Pinch-Exergy
Iran’s vast common natural gas resources and the necessity to extract and export it as Liquefied Natural Gas (LNG) to distances more than 3000Km opens a lucrative field for researchers to optimize LNG cycles. In this article heat integration in cryogenic cycles by determining interacycle partition temperature and optimizing refrigeration features like Subcooler, Presaturator, aftercooler, reboi...
