Simulation and performance optimization of finned tube gas cooler for transcritical CO2 refrigeration system in Indian context.
Author(s) : GUPTA D. K., DASGUPTA M. S.
Type of article: Article, IJR article
Summary
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 for the performance analysis at various design and operating conditions. A combination of input parameters is employed anticipating that it will enhance heat transfer, reduce the approach temperature and eventually improve the COP of refrigeration system. As the paper reiterates the success of CO2 as refrigerant, it emphasizes upon operating parameters that are based on local environmental conditions for best possible performance of overall system including fan power consumption. Thus the paper help to formulate design guidelines for optimized performance of gas cooler at different ambient temperatures.
