🔍 Key Concepts

• Flow path of refrigerant vapor and air/non‑condensable gases into and out of the carbon filter tank in the schematic • What happens in step (3) and step (4) as written beside the carbon filter tank • The purpose of an activated carbon filter in a purge recovery system (what it is meant to retain vs what it lets pass/vent)

💭 Think About

• Trace the mixture that leaves the purge chamber: when it enters the carbon filter tank, which component (refrigerant or air/non‑condensables) does the note say is absorbed and which one is later vented? • Look at the pressure changes: as the tank pressure rises, what is building up inside—refrigerant or air? When the vent opens at 10 psig, what does the label say is being purged? • Ask yourself: for an efficient recovery unit, which substance do we want to keep and return to the chiller, and which substance do we want to discharge overboard or to atmosphere?

✅ Before You Answer

• Read the text for step (3) next to the carbon filter tank and match the word absorbs with the correct substance. • Read the text for step (4) and see which substances are identified as being purged/vented from the tank. • Confirm that the correct choice states that the carbon pellets have an affinity for the same substance that is said to be absorbed in step (3), and not for the substance that is vented in step (4).
