← TechnologyWhich cooling outcome occurs when refrigerant mass becomes critically low in a heat pump system?
A)Compressor overheating and potential seizure✓
B)Evaporator coil experiences heavy frosting
C)Increased thermal efficiency and decreased power draw
D)Uniformly distributed cooling capacity enhancement
💡 Explanation
Compressor overheating can result due to insufficient refrigerant. Oil transports through the refrigerant's mass via convection. Therefore, reduced mass weakens the oil-cooling action; rather than uniform cooling or efficiency enhancement, the compressor overheats, risking seizure.
