🔍 Key Concepts

• Non-condensable gases in a refrigeration system and why they are a problem • Difference between moisture, oil, and refrigerant in the system • Normal purpose of a purge unit on larger refrigeration/AC plants

💭 Think About

• Which of the options describes something that cannot change from gas to liquid in the condenser and would build up at the top of the system? • Think about what component is usually fitted with a purge connection: is it placed where oil collects, where water collects, or where unwanted gases collect? • If you perform purging too often, which of these four things would you risk losing from the system, and which is specifically what the purge is designed to target?

✅ Before You Answer

• Be clear on what non-condensable means: a gas that will not liquefy at the system’s normal condensing pressure/temperature • Recall that moisture is usually removed by dryers/filters, not by the purge system • Confirm that reducing the amount of refrigerant in the system is not a normal goal of routine maintenance, but an indication of a leak or charging adjustment
