← TechnologyWhich consequence results when refrigerant subcooling is lost prior to the compressor's scroll pump in an HVAC system?
A)Suction line flash vaporization rises✓
B)Condenser phase changes significantly speed
C)Compression ratios proportionately diminish
D)Discharge pressure drops substantially too
💡 Explanation
Increased bubbles entering the compressor scroll reduce volumetric efficiency because vapor occupies space meant for liquid; cavitation can result. Therefore, suction line flash vaporization rises, rather than efficient compression, impairing cooling system performance and lifecycle.
