In this paper, the performance characteristics of R404 indirect refrigeration system using R744 as a secondary refrigerant were investigated experimentally to obtain optimum design data for system. First, constant experimental conditions, COP R404A refrigerants decreases with respect increases in condensation temperature and difference cooler. And, slightly decreasing mass flowrate R744.
