Type II — High-Pressure第 142 / 240 题
During recovery from a Type II system, a technician sees noncondensable gases (air) collected in the recovery cylinder. What is the correct handling under Section 608?
a.Release the noncondensables and refrigerant together into a ventilated room
b.Purge only noncondensables, never refrigerant
c.Vent the whole cylinder and start over
d.Add the mixture back into the customer's system as is
解析
Regulated refrigerant must never be vented, so a technician cannot simply release the cylinder contents. Only genuine noncondensables may be purged, and only using proper recovery/recycling equipment and procedures that do not release refrigerant. Reusing a mixture contaminated with air can damage the system and reduce performance.
