Q

If increasing the cooling water flow to a refrigeration condenser fails to lower the condenser pressure, the probable cause may be due to what condition?

🔍 Key Concepts

• Condenser pressure and how it relates to heat rejection in a refrigeration system • Effect of cooling water flow on a properly operating condenser • How non‑condensable gases or refrigerant charge issues influence condenser pressure

💭 Think About

• Ask yourself: if you increase cooling water flow and pressure does NOT drop, what does that say about the condenser’s ability to transfer heat? • Which option would cause the condenser pressure to stay high even if the condenser surfaces are being well cooled? • Which choices mainly affect the low‑side (evaporator/expansion valve) rather than the high‑side (condenser/receiver) of the system?

✅ Before You Answer

• Identify which components/conditions directly affect high‑side pressure (condenser and receiver) versus low‑side pressure. • Check which option would result in reduced effective condensing surface or a medium that cannot be condensed, keeping pressure high. • Eliminate any choices that mainly cause low suction pressure or poor evaporator performance rather than high condenser pressure.
