Which outcome occurs when reciprocating compressor valves overheat?

💡 Explanation

Reduced volumetric efficiency occurs because excessive heat induces greater refrigerant density changes inside the cylinder; therefore, it limits suction effectiveness rather than increasing oil viscosity. Valves face more pressure and temperature extremes rather than less cooling.
