原始语种摘要: Cascade refrigeration systems work with two or more cycles in serial and can obtain internal temperatures below -80°C, necessary to several activities in medicine and scientific research. The main objective of this paper is to present a thermodynamic analysis of three stages vapour compression cascade refrigeration system with the use of HFO refrigerants in the high temperature cycle and HFO and HFC refrigerants in intermediate (medium temperature cycle and HFC refrigerants & hydrocarbon fluids in the low temperature cycle. The energy and exergy analysis for three stages cascade vapour compression refrigeration systems were carried out for two different conditions (i) temperature 103oC and (ii) 95oC and thermodynamic model based on the law of conservation of mass, on the first and second...
