What process describes cleaning refrigerant for reuse through distillation and filtering?

The process of cleaning refrigerant for reuse through distillation and filtering is best described as refrigerant recycling. This process involves the collection of used refrigerant, which may contain contaminants, and subjecting it to various methods to remove impurities.

Refrigerant recycling typically includes steps like distillation, where the refrigerant is heated to separate pure refrigerant from contaminants based on differences in boiling points. Additionally, filtering helps capture particulate matter and other unwanted substances. By recycling refrigerant, it can be reused safely in HVAC systems, thereby conserving resources and minimizing environmental impact.

In contrast to recycling, the other terms refer to slightly different processes. Purification generally refers to the overall cleaning process without specifying techniques like distillation. Reclaiming usually implies a higher standard of cleanliness and typically involves returning refrigerant to a specification set by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) or the Environmental Protection Agency (EPA). Restoration may suggest bringing refrigerant back to its original conditions but isn't commonly used in professional terminology related to refrigerants.

Thus, refrigerant recycling is clearly the process that encapsulates the techniques involved in cleaning refrigerant for reuse, which is essential for efficient and responsible management of refrigerants in HVAC applications
