Abstract: In cooling systems, besides the refrigerant preferences, the probability of leakage due to dynamic conditions increases energy consumption and emissions directly or indirectly. In this study, thermodynamics and environmental performances of transport refrigeration systems using different and alternative refrigerants were examined. Leakage effects of refrigerants on the environment were investigated in terms of energy consumption and emission loads based on the coefficient of performance, exergy efficiency and improvement potentials. R152A stands out between the refrigerants taken as a reference with aspects of cooling capacity, environmental effects and refrigerant charge amount.

Keywords: transport refrigeration; coefficient of performance; COP; exergy analysis; leakage rate; CO2 emission.
