Abstract

Attempts to reduce the negative impact on the environment have led, among other things, to the use of so-called natural refrigerants. One of which is SO2. At food processing enterprises, this refrigerant is used in two main cycles - cascade and transcritical. Along with the negative impact on the environment, it is also necessary to take into account the increase in the efficiency of refrigeration plants, which is especially important for transcritical cycles. The purpose of the study was to develop a method for calculating and analyzing the transcritical cycle of SO2 with parallel compression and an ejector. The calculation of the transcritical cycle is based on the fundamental laws of thermodynamics, the analysis method is based on the entropy-statistical method of thermodynamic analysis. Cycle calculation includes analysis of compression loss by system components. Description of operation of transcritical cycle of SO2 with parallel compression and ejector with two temperature levels is given, procedure of calculation and analysis of losses in elements of refrigerating unit operating according to transcritical cycle of SO2 with parallel compression and ejector is given. The use of this method allows you to identify the elements and processes with the greatest losses and take further measures to improve the efficiency of the refrigeration system.
采用并联压缩和喷射器的跨临界循环 CO2 的计算和分析程序
为了减少对环境的负面影响,人们开始使用所谓的天然制冷剂。二氧化硫就是其中之一。在食品加工企业中,这种制冷剂主要用于两个循环--级联循环和跨临界循环。除了对环境的负面影响外,还必须考虑提高制冷设备的效率,这对跨临界循环尤为重要。这项研究的目的是开发一种计算和分析具有平行压缩和喷射器的二氧化硫跨临界循环的方法。跨临界循环的计算基于热力学基本定律,分析方法基于热力学分析的熵统计法。循环计算包括系统组件压缩损失分析。文中描述了具有并联压缩和喷射器的二氧化硫跨临界循环在两个温度等级下的运行情况,并给出了按照具有并联压缩和喷射器的二氧化硫跨临界循环运行的制冷装置元件损耗的计算和分析程序。使用这种方法可以确定损失最大的元件和过程,并采取进一步措施提高制冷系统的效率。
