在冷库制冷工艺设计中,如何提高制冷循环的经济性,节约能源,是人们所关注的问题,对制冷循环的经济性习惯上常采用制冷系数ε即ε=(80)/(A1)来评价,近年来在制冷技术中越来越多地采用(火用)分析法来评价制冷循环的经济性。从每一循环的(火用)损找出薄弱环节,为提高循环的经济性提出改进措施。本文就以氨制冷循环系统采用如下节能方案后对循环经济性的影响进行(火用)分析。
In the design of cold storage refrigeration process, how to improve the economy of the refrigeration cycle and save energy is a problem that people are concerned about. The refrigeration cycle is often evaluated by the refrigeration coefficient ε = (80) / (A1) In recent years, the exergy analysis has been increasingly used in refrigeration technology to evaluate the economics of refrigeration cycles. From the (exergy) loss of each cycle to identify the weak links, to improve the economy of the circular proposed improvements. In this paper, the following exergy analysis of the impact of circular economy on the ammonia refrigeration cycle system using the following energy-saving solutions.
