In this paper, the CO2 booster supermarket’s refrigeration systems are analyzed. The analysis has included a standard booster (CB1), a booster with parallel compression (CB2), four configurations of the booster with dedicated mechanical subcooling (CB3), and an R404A multiplex direct expansion refrigeration system. The thermodynamic analysis of the different configurations of the CO2 refrigeration systems are described in this paper. The CB3 system has four different configurations in this investigation that uses refrigerants like R134a, R290, R1234ze, and R1234yf. From the investigation, the following parameters are compared for all investigated systems: COP, total power input, optimal gas cooler pressure, and flash gas mass flow rate. The performance and power input of all investigated systems are compared with an R404A multiplex DX refrigeration system for supermarkets in warm climates. Finally, the results from this investigation are concluded in brief.
