🔍 Key Concepts

• Relationship between condensing (head) pressure and condenser heat rejection • Effect of non‑condensable gases trapped in the condenser on system pressure and temperature • Difference between problems that affect condenser performance vs. those that affect the evaporator or liquid line

💭 Think About

• If the cooling water inlet temperature has not changed, what would make the condenser operate at a higher pressure to reject the same amount of heat? • Which option(s) would directly sit in the condenser space and reduce its effective heat‑transfer/condensing area? • Which choices would mainly affect suction pressure, evaporator performance, or liquid flow, rather than the discharge (head) pressure?

✅ Before You Answer

• Identify which choice would add a gas that does not condense at normal condenser temperatures. • Eliminate any options that would primarily change suction pressure or evaporator performance instead of discharge (head) pressure. • Consider which fault would make the compressor work against a higher condensing pressure even though cooling water temperature is unchanged.
