Refrigerant reclamation recycles used refrigerant, restoring it to usable form, which helps reduce environmental impact in HVAC systems.

Refrigerant Reclamation is the process of recovering and restoring used refrigerant to meet the standards required for new refrigerant. This process begins with recovery, which is the removal of refrigerant from an HVAC system into a storage container. Here’s a breakdown of key terms defined by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE):

• Recover: Removing refrigerant from a system and storing it externally.
• Recycle: Reducing contaminants in used refrigerants, such as oil and non-condensables, by filtering and drying.
• Reclaim: Processing used refrigerant to meet new-product specifications, ensuring it’s as pure as unused refrigerant.

Importance of Refrigerant Recovery and Reclamation

Proper refrigerant handling is essential for environmental protection, as refrigerants like R-22 and R-410A can significantly impact the ozone layer and contribute to global warming. Recovery and reclamation prevent these refrigerants from being released into the atmosphere.

When is Refrigerant Recovery Necessary?

Refrigerant recovery typically happens in two scenarios:

1. During Repairs: For air conditioning repairs involving refrigerant lines.
2. During Replacement: Recovering refrigerant from older systems when replacing them.

Refrigerant Recovery Process

Only certified HVAC professionals are authorized to perform refrigerant recovery, as it requires specialized recovery equipment. Here’s how the process works:

1. Connection: The technician connects recovery hoses from the unit to a refrigerant recovery machine and then to a recovery cylinder.
2. Recovery: By opening specific valves, refrigerant exits the unit, flows through the recovery machine, and fills the recovery tank.
3. Disposal or Recharge: The technician can either recharge the refrigerant into the repaired system or take it to an HVAC supply location for recycling.

Techniques for Refrigerant Recovery

Technicians choose recovery methods based on factors such as system type and refrigerant volume. Whether it’s for repairs or a new system installation, refrigerant recovery prevents environmental harm, as even a small release of R-410A can have the equivalent impact of releasing a ton of carbon dioxide.

EPA regulations require all HVAC professionals to safely recover, recycle, or recharge refrigerants to protect the environment. Proper handling of refrigerants not only ensures compliance but also reduces the impact of HVAC systems on climate change.
