Which risk increases when reciprocating HVAC compressor inlet valve fails to fully close?

💡 Explanation

When the suction valve fails to close fully, hot compressed refrigerant backflows into the cylinder during intake stroke, carrying waste heat and increasing discharge superheat because cylinder isnt properly insulated. Therefore overheating of the discharge line results, rather than refrigerant overflow, dilution floodback, or increased motor torque requiring proper functioning components to provide needed effect.
