What distinguishes reclaiming refrigerant from recycling it?
- AReclaiming returns the refrigerant to the same appliance it was removed from
- BReclaiming reprocesses refrigerant to a specification verified by chemical analysis
- CReclaiming removes the refrigerant from the appliance and stores it in a cylinder
- DReclaiming cleans the refrigerant by oil separation and passes through a filter-drier
Show answer and rationale
Correct: B. Reclaiming means reprocessing to new-product purity, confirmed by chemical analysis against the AHRI 700 standard. It cannot be done on a job site, which is the practical consequence the exam is testing.
- C — That describes recovery, which is simply removing refrigerant and storing it externally.
- D — That describes recycling, a field-level clean-up that does not meet the reclaim specification.
- A — Where the refrigerant ends up does not define the term; the purity standard reached does.
