What is true concerning the accumulation of air and other non-condensable gases in a refrigeration system?

🔍 Key Concepts

• Behavior of non-condensable gases in a closed refrigeration system • Where gases that cannot condense at operating condenser temperature/pressure will migrate and accumulate • Effect of non-condensables on condenser pressure, temperature, and heat transfer efficiency

💭 Think About

• In a refrigeration system, ask yourself: where does the hottest, highest-pressure vapor go, and what happens to gases that do NOT change phase there? • Think about which component is designed to hold liquid refrigerant versus reject heat from hot vapor—where would unwanted gases interfere the most? • Consider which option would most likely raise head pressure and reduce the ability of the system to reject heat to seawater/air.

✅ Before You Answer

• Identify which component (from the choices) is primarily a heat-rejection/condensing surface for hot vapor. • Recall that non-condensable gases do not turn to liquid at normal operating conditions—so they will stay in the vapor space of which component? • Ask: which effect listed in the choices is directly linked to trapped vapor and higher condenser pressure, rather than a liquid-side or lubrication-side problem?
