Abstract

Objective. The purpose of the study is to determine the prospects for using a membrane refrigeration unit for the production of cold as an alternative to absorption. Method. The study was carried out using a numerical experiment and verification of the results obtained on an experimental bench. Result. An analysis was made of the use of a traditional absorption refrigeration machine and a membrane refrigeration machine from the point of view of energy efficiency and the number of working elements. Presented for comparison are methods for calculating the separation process of the “absorbent-refrigerant” mixture based on reverse osmosis processes and a water-ammonia absorption refrigeration unit. Conclusion. The use of separation processes in membrane apparatuses for the production of cold in mixed refrigeration machines, as an alternative to absorption refrigeration machines, will ensure a more stable process for obtaining refrigerant from the mixture, reduce material costs for the production of a refrigeration unit and increase the energy efficiency of a refrigeration unit operating on mixed components.
使用膜制冷装置替代吸收式制冷的前景
目的。本研究的目的是确定使用膜制冷装置制冷的前景,以替代吸收式制冷。方法。通过数值实验和验证实验台获得的结果进行研究。结果。从能源效率和工作元件数量的角度分析了传统吸收式制冷机和膜制冷机的使用情况。为进行比较,提出了基于反渗透过程的 "吸收-制冷剂 "混合物分离过程的计算方法和水-氨吸收制冷机组。结论作为吸收式制冷机的替代品,在混合式制冷机中使用膜设备进行冷生产的分离过程将确保从混合物中获得制冷剂的过程更加稳定,降低制冷设备生产的材料成本,并提高使用混合成分的制冷设备的能源效率。
