With each passing day, more laws around the world are prohibiting the venting of refrigerants during service/alteration/removal work.
Refrigerant recovery can take place at any one of three stages during the lifecycle of air conditioning equipment:
• During servicing, when a partial or complete refrigerant charge is removed from the system;
• When the system is converted to run with a new refrigerant; and
• Before the equipment is scrapped and disposed.
Of the three stages, conversion is rare in a system’s lifetime; the system can still operate even after a refrigerant becomes obsolete. The large refrigerant charges and climbing refrigerant costs have been the most positive incentives for recovery.
