Recovery & RecyclingCâu 219 / 240
Recovering liquid refrigerant before vapor on a large system is recommended because it:
a.Prevents the cylinder from overfilling
b.Cleans the refrigerant
c.Removes the bulk of the charge much faster
d.Is required before recycling
Giải thích
Pulling liquid first moves the largest portion of the charge quickly, then vapor recovery finishes drawing the system down to the required level. This shortens the job significantly on a big system. It is a technique choice, not a cleaning or a legal recycling prerequisite.
