Question 1

Which of the following processes requires refrigerant to be reprocessed to meet AHRI Standard 700 specifications before it can be resold?

Accepted Answer

Reclaiming

Answer

Reclaiming is the process of reprocessing a refrigerant to new product specifications, which are verified by chemical analysis. According to EPA regulations, reclaimed refrigerant must meet the purity levels specified in AHRI Standard 700 before it can be sold to a new owner.

If a recovered refrigerant changes ownership, it must be reclaimed by an EPA-certified refrigerant reclaimer to ensure it meets the required purity standards before being sold to a new owner.

Question 5

Which piece of equipment is designed to clean refrigerant on-site by removing oil, moisture, and other contaminants so it can be reused in a system owned by the same person?

Accepted Answer

A recycling unit

Answer

Recycling equipment is used to clean refrigerant by extracting it and passing it through devices like filter-driers to reduce contaminants. This allows the refrigerant to be reused in equipment belonging to the same owner.
