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.Vent the whole cylinder and start over
b.Do not vent regulated refrigerant; separate or purge only true noncondensables per proper procedure and equipment, never releasing refrigerant
c.Release the noncondensables and refrigerant together into a ventilated room
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.
