Question 3

What is the primary difference between refrigerant 'recovery' and refrigerant 'recycling'?

Accepted Answer

Recovery removes refrigerant; recycling cleans it for reuse on-site

Answer

Recovery means removing refrigerant from a system into an external container, while recycling means cleaning that refrigerant for reuse without meeting ARI 700 purity standards.

Question 4

Which organization sets the purity standard (ARI 700) that reclaimed refrigerant must meet before it can be resold?

Accepted Answer

Air-Conditioning, Heating, and Refrigeration Institute (AHRI)

Answer

AHRI Standard 700 specifies the purity levels that reclaimed refrigerant must meet to be sold as virgin-equivalent product.

Question 5

When recovering refrigerant from a system with a non-operating compressor, which recovery method is most appropriate?

Accepted Answer

Push-pull recovery method

Answer

The push-pull method is most effective for inoperative systems because it simultaneously pushes liquid and pulls vapor without relying on the system's own compressor.
