In this paper, a comparative study of CO2 and water-based brine secondary cooling systems for refrigeration applications is presented. CO2 secondary systems are simple and could prove to be attractive for high temperature (HT) and medium temperature (MT) in industrial and commercial refrigeration applications regardless of climate. Calculations show that CO2 secondary systems give a possibility of energy savings in the range of 10–20% for HT systems and more than 20–30% for MT systems. The design and particular challenges of CO2 systems are discussed. The analysis is illustrated by case studies. Further possibilities to optimized secondary CO2 systems by modulating pressure or applying frequency converters are discussed. The use of secondary CO2 systems in commercial refrigeration installations (supermarket systems) is briefly discussed.
