🔍 Key Concepts

• Discharge head pressure behavior in a reciprocating compressor when heat is not being removed properly vs when refrigerant flow is reduced • Effect of cooling water flow through the condenser on condensing pressure and temperature • How air or non‑condensable gases trapped in a refrigerant condenser typically affect system pressures

💭 Think About

• Think about what happens to discharge pressure if the condenser is not rejecting enough heat to the cooling medium: does pressure go up or down? • Consider how air or non‑condensables in the condenser would affect the condensing temperature and pressure compared to normal operation. • Ask yourself which condition would more likely cause the compressor to move less refrigerant mass per stroke, and how that would show up in head (discharge) pressure readings.

✅ Before You Answer

• Verify whether insufficient condenser cooling tends to cause high or low head pressure in vapor‑compression systems. • Check how air in the condenser usually affects system pressure: does it increase or decrease condensing pressure? • Consider whether leaky suction valves change the effective compression of the gas and how that would influence measured discharge head pressure.
