🔍 Key Concepts

• Difference between non-condensable gases and moisture (water) in a refrigerant system • How a dehydrator / filter-drier works in refrigeration systems • The normal function of oil separators and condensers

💭 Think About

• Which component in a refrigeration or recycling system is specifically designed to remove water (moisture) from the refrigerant? • Do non‑condensable gases being vented from the top of a cylinder necessarily remove dissolved or entrained water from the refrigerant? Why or why not? • What is the usual purpose of a condenser and an oil separator in a refrigeration system—are they intended to remove moisture, or something else?

✅ Before You Answer

• Identify which choice describes a device whose primary function is to absorb or trap moisture from refrigerant. • Confirm that the option you choose is a standard, textbook method for drying refrigerant in recovery/recycling equipment. • Eliminate any option that mainly deals with removing gases, oil, or heat rather than specifically removing water.
