Chapter Review

Reclaiming Refrigerant

Reclaiming refrigerant reprocesses the material to virgin purity. For sources of

reclaimed refrigerant or to send refrigerant for reclamation, contact the EPA,

the independent industry organizations, or your state’s Department of Ecology.

Chapter Review • Common refrigerants have varying properties and operating pressures. • New laws

require that we standardize our refrigerant processing

methods throughout the industry. This includes the processes

that handle refrigerant, including

recovering

and

recycling

,

which are the most economic and environmentally friendly ways

of handling the refrigerant.

Recovery/recycle

processes deal directly with the refrigerant.

During

recovery

the refrigerant is removed from the AC system.

During

recycling

it is restored to reusable condition by removing

moisture, acidity, and particulate matter.

• The

flushing

procedure removes contaminants from the AC sys-

tem hoses, evaporator, and condenser. The

evacuation

process

removes air and moisture from the AC system. This is necessary

before adding new or recycled refrigerant. The process of adding

refrigerant is called

charging

.

Reclaiming

a refrigerant means processing the refrigerant so

that it meets standards for new refrigerant.
