Recovery & RecyclingCâu 232 / 240
Why is identifying the refrigerant before recovery especially important today?
a.Because all refrigerants are now identical
b.Because it lowers recovery pressure
c.Because it changes the cylinder color
d.Because contaminated or mixed charges can ruin equipment and cannot be reclaimed
Giải thích
With many refrigerants in the field and counterfeit or mixed charges circulating, identifying refrigerant first protects your recovery machine and cylinder from contamination and preserves the refrigerant's value for reclamation. A mixed batch usually cannot be reclaimed and must be destroyed. A refrigerant identifier is a small investment against a costly mistake.
