← TechnologyWhich outcome occurs due to heat accumulation in a vapor-compression system?
A)Reduced volumetric efficiency.✓
B)Increased refrigerant subcooling.
C)Higher evaporator pressure.
D)Decreased superheat at compressor
💡 Explanation
Reduced compression occurs because superheating of the refrigerant inside the compressor cylinder increases the gas specific volume; therefore, volumetric efficiency drops and refrigerant flow reduces accordingly, rather than improved cooling or pressure changes occurring directly in response to accumulated heat.
