Recovery & Recycling第 240 / 240 题
Which statement best distinguishes recovery, recycling, and reclamation?
a.All three verify purity by chemical analysis
b.All three require a certified reclaimer
c.All three may be done by anyone
d.Recovery removes and stores, recycling cleans for reuse, and only reclamation verifies AHRI 700 purity by chemical analysis
解析
Recovery merely removes and stores refrigerant; recycling cleans it of oil, moisture, and acid for reuse without a purity test; and reclamation reprocesses it to AHRI 700 purity verified by chemical analysis, and only a certified reclaimer may do it. This layered definition is among the most frequently tested facts on the exam.
