For a positive displacement compressor, the compressor power is approximately proportional to the compressor speed.
Since the required compressor displacement for HC-600a refrigerant is almost double that of HFC-134a to achieve identical capacity and since the larger bore size increases piston-cylinder clearance and a small displacement compressor increases re-expansion volume, raising volumetric efficiency in small refrigerating-capacity compressors is difficult.
