ANALYSIS OF THE SINGLE-STAGE REFRIGERATION CYCLE PARAMETERS OPERATING WITH R22/R410A/R32 REFRIGERANTS BY MATLAB/SIMULINK SOFTWARE

Abstract

The paper was presented simulation results of single-stage vapor-compression refrigeration system. Parameters of refrigerant and refrigeration cycle uses R22, R410A and R32 refrigerants based on Matlab/Simulink software. The system was simulated with a cooling capacity of 9000 BTU/h (2,638 kW), evaporation temperature was 5⁰ C and condensation temperature was 40⁰ C. The simulation process has determined the state parameters and the temperature affection which impacted on the single-stage refrigeration system. The simulation results are achieved at the same operating temperature and equivalent cooling capacity to compressor displacement uses R22 refrigerant higher 31%, 37% than R410A/R32 and the Coefficient of Performance (COP) are 5,581 (R22)/5,177 (R410A)/5,396 (R32).
