Recovery & Recycling第 214 / 240 题
Recycling refrigerant, as opposed to reclaiming it, means the refrigerant is:
a.Destroyed by incineration
b.Cleaned for reuse on-site
c.Chemically analyzed to AHRI 700
d.Vented after filtering
解析
Recycling reduces a refrigerant's oil, moisture, and acidity using an oil separator and filter-driers so it can be reused, typically on-site or at a local shop, without a chemical purity analysis. Reclamation goes further, verifying AHRI 700 purity by chemical analysis. Recycled refrigerant generally stays with the same owner.
