Refrigerant recovery and recycling
The need to adopt refrigerant conservation has led the industry to
develop a specific terminology which is used in this section.
According ISO 11650 standard, these definitions are:
• Recovery means to remove refrigerant in any condition from a system
and store it in an external container. Practical aspects of recovery
procedures, and examples of refrigerant recovery operations in
refrigeration equipment and systems how this might be done.
• Recycling means to extract refrigerant from an appliance and
clean it using oil separation and single or multiple passes through
filter-driers which reduce moisture, acidity, and particulate matter.
Recycling normally takes place at the field job site.
