In this study, the performance of an alumina nanofluid cooled double pipe gas cooler for trans-critical CO2 refrigeration cycle is theoretically compared to that of water cooled gas cooler. Equal pumping power comparison ...

Carbon Dioxide (CO2) refrigeration system in trans-critical cycle, requires modification to improve the overall performance. This modification become more prominent when it will be used in tropical regions like India. There ...

This paper analyzes trans-critical CO2 refrigeration system in typical Indian conditions and the challenges associated with it. A mathematical model for air cooled finned tube gas cooler is developed, validated and used ...
