← TechnologyWhich outcome occurs when differential vapor pressure is increased within an R-134a refrigeration pump?
A)Compressor efficiency significantly degrades✓
B)Thermal expansion valve remains closed
C)Complete phase change to solid
D)Decreased superheat at the evaporator
💡 Explanation
Inefficient compression results because increased differential vapor pressure forces the refrigerant to condense prematurely entering the pump (known as vapor lock). Therefore, the compressor struggles to maintain flow rather than allowing efficient gaseous compression.
