Analysis of compression–absorption cascade refrigeration cycles

Applied Thermal Engineering, 2012
Abstract In this study, LiBr–H2O pair was used for the first time for absorption section of compression–absorption cascade refrigeration cycles. These cycles were analyzed theoretically and compared with using different refrigerants in the compression and absorption sections.

Compression–absorption cascade refrigeration system

Applied Thermal Engineering, 2006
This paper describes the study carried out to analyse a refrigeration system in cascade with a compression system at the low temperature stage and an absorption system at the high temperature stage to generate cooling at low temperatures, as well as the possibility of powering it by means of a cogeneration system.

Theory of cascade refrigeration

AIP Conference Proceedings, 2012
The maximum difference between the warm and cold temperature of a refrigeration cycle is limited by properties of the refrigerant and/or losses associated with the transport of the refrigerant. For larger temperature differences, one has to arrange several refrigeration cycles “above” each other, each cycle spanning a certain temperature difference ...

Performance Experiment of Natural Refrigerant Cascaded Refrigeration System

Advanced Materials Research, 2011
In this paper, the performances of natural refrigerant R290/CO2 cascaded refrigeration system using R290 as high temperature cycle refrigerant and CO2 as low temperature cycle refrigerant were investigated experimentally. The test results show that both CO2 compressor and R290 compressor start up stably and present good running performance.

Analysis of Cascade Vapour Refrigeration System with Various Refrigerants

Materials Today: Proceedings, 2019
Abstract In this paper report the performance analysis of different refrigerants couples in cascade refrigeration system. Refrigerants such as R134a/R23, R410A/R23 and R404A/R170 have been successfully analyzed in the superheating and sub cooling range of 10 °C and 5 °C respectively. The variation in condenser temperature was from 30 to 50 °C in high

Refrigerant conversion of auto-refrigerating cascade (ARC) systems

International Journal of Refrigeration, 1997
Abstract This paper describes converting Auto-Refrigerating Cascade (ARC) ultra-low temperature systems from a multicomponent zeotropic working fluid containing CFS to a CFC-free mixture. The differences between azeotropes, mixtures and blends with minimal glides used in conventional refrigeration systems and the steep glide (wide span) zeotropes ...
