🔍 Key Concepts

• behavior of refrigerants when charged into a system under deep vacuum • how moisture and non‑condensable gases can enter or affect a refrigeration system • what components like purge units, rupture disks, and secondary refrigerants are designed to protect or control

💭 Think About

• Think about what happens inside the system when you introduce a liquid refrigerant into a space that is at a very low (deep) vacuum. What does this do to pressure and temperature? • Which of the listed options describes a situation that would be especially risky or undesirable if air or moisture were to be drawn in while charging? • Consider the normal purpose of a purge unit, a rupture disk, and a secondary refrigerant—under what conditions would each typically be activated or affected?

✅ Before You Answer

• Verify which option is directly related to air and moisture infiltration versus over‑pressure protection or low‑temperature effects. • Check which component (purge unit, rupture disk, secondary refrigerant) is normally intended as a safety/maintenance device, not the primary concern when charging under vacuum. • Ask yourself: under a deep vacuum, is the system more at risk of drawing something in from outside or forcing something out due to high internal pressure?
