Physics-based model shows drop-in low-GWP refrigerants cause performance penalties in scroll compressors
A new mechanistic scroll compressor model, validated with R290 and R454C, demonstrates that using these low-GWP refrigerants as drop-in replacements in an R410A-designed unit can lead to significant performance penalties due to vapour density mismatch. The framework, published in Applied Thermal Engineering, provides a basis for refrigerant-specific compressor redesign.
