Abstract

The adverse effects on the earth's atmosphere due to the use of non-environmentally friendly refrigerants have increased significantly which has resulted in an increase in Ozone Depletion Potential (ODP) and Global Warming Potential (GWP). This phenomenon encourages industries to use natural alternative refrigerants such as ammonia (NH3) and carbon dioxide (CO2). The application of a cascade refrigeration system that uses CO2 refrigerant on the Low- Temperature Circuit (LTC) and NH3 on the High-Temperature Circuit (HTC) becomes an excellent alternative to the application of fish freezing at low temperatures. In this paper, a cascade refrigeration system with CO2 working fluid on the LTC and NH3 on the HTC have been analyzed. Design and operation parameters considered in this study include evaporation temperature, a temperature difference in the cascade heat exchanger, condensation temperature, suction and discharge pressure on the system.
