Performance of CO2 Trans-Critical Refrigeration System with Work Recovery Turbine in Indian Context

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 are many modifications in the basic cycles are possible to improve the performance and to adopt the conditions as per requirements and applications. In this paper, a simulation based study has been carried out to analyze the performance of modified CO2 trans-critical refrigeration system with work recovery turbine. The paper emphasizes upon design and operating parameters based on local environmental conditions for the best possible performance.
