  author={Satya N. Tripathy and Jibanananda Jena and Dillip K. Padhiary and Manmatha K. Roul},
Thermodynamic analysis of a cascade refrigeration system that uses carbon dioxide-ammonia (R744-R717) as refrigerant is presented in this paper to determine the optimum condensing temperature of the cascade condenser at given design parameters, to maximize the COP of the system. The design and operating parameters considered in this study include (1) condensing, sub cooling, evaporating and super heating temperatures in the ammonia (R717) high-temperature circuit, (2) temperature difference in…

Energy and Exergy Analysis of Cascade Refrigeration System Using MC22 and MC134 on HTC, R404A and R502 on LTC

Low temperature storage with a single refrigeration system only stable up to 228 K temperature. The purpose of this study is to develop a low temperature cool storage with cascade refrigeration

Thermo-economic analysis and multi-objective optimization of vapour cascade refrigeration system using different refrigerant combinations

A numerical investigation of energetic, exergetic, economic and environmental performances of a 50-kW cooling capacity cascade refrigeration system using four different refrigerant pairs, namely



Carbon dioxide for use as a refrigerant.

This study documents the actual performance of a large plant operating with R-744 (CO2) refrigerant and compares these results with those found on an alternative system using a more conventional

CO2 Transcritical Cycles for High Temperature Applications

A breadboard CO2 prototype heat pump for stationary applications was designed, constructed, and tested. Test results of the CO2 prototype showed about 12% lower cooling capacity but a similar

NH3/CO2 supermarket refrigeration system with CO2 in the cooling and freezing section: technical, energetic and economical issues.

The first supermarket refrigeration system in the Netherlands with only natural refrigerants became operational in March 2004 and is located in Bunschoten. The NH3/CO2 cascade system has NH3 as

Experimental investigation of the CO{sub 2} refrigeration cycle

Worldwide efforts to reduce the environmentally harmful effects of chlorofluorocarbons revived the study of the CO{sub 2} refrigeration cycle. A laboratory prototype of the CO{sub 2} refrigeration
