← TechnologyWhich risk increases when the condenser of a residential heat pump is significantly undersized for the specified refrigerant?
A)Compressor overheating and eventual failure✓
B)Reduced evaporator superheat temperature stability
C)Increased expansion valve efficiency fluctuation
D)Refrigerant subcooling performance improvement decreases
💡 Explanation
Compressor overheating increases because volumetric efficiency decreases as refrigerant discharge pressure rises in "vapor-compression" refrigeration, therefore leading to higher motor current and heat. Lower discharge pressure allows improved efficiency cooling rather than compressor stress.
