PERFORMANCE OF ALTERNATIVE REFRIGERANTS FROM A SYSTEM'S PERSPECTIVE.

Author(s) : SPATZ M. W.

Summary

IN THE PAPER THE RESULTS OF MODELING A REPRESENTATIVE 3-TON AIR-TO-AIR HEAT PUMP RUNNING WITH THE BASELINE REFRIGERANT (R22) AND ZERO ODP ALTERNATIVE REFRIGERANTS ARE PRESENTED. THE MODEL IS VALIDATED USING TEST RESULTS OF THE 3-TON HEAT PUMP. BASELINE SIMULATION RUNS WITH R22 UTILIZE COMPRESSOR MAPS GENERATED FROM COMPRESSOR CALORIMETER TESTS. ALTERNATIVE REFRIGERANT SIMULATION RUNS ARE MADE WITH 2 PURE FLUIDS (R134A AND R152A) ANDAN AZEOTROPIC MIXTURE (60/40 WT %) OF R32 AND R125. THE EXPANSION DEVICE, THE HEAT EXCHANGERS, AND LINE SIZES ARE OPTIMIZED FOR EACH REFRIGERANT. COMPRESSOR LOSSES AND EFFICIENCIES FROM THE BASELINE RUNS ARE USED FOR THE ALTERNATIVE REFRIGERANT RUNS TO SIMULATE AN OPTIMIZED COMPRESSOR FOR THESE REFRIGERANTS. PRE-OPTIMIZED AND POST-OPTIMIZED SYSTEM PERFORMANCE IS PRESENTED TO DEMONSTRATE THE IMPACT OF THIS PROCESS ON THE RANKING OF REPLACEMENT REFRIGERANTS.
