What is the process of removing refrigerant from a unit and storing it in an external container without cleaning it called?

The process of removing refrigerant from a unit and storing it in an external container without cleaning it is known as recovery. During recovery, the refrigerant is extracted from the system and placed into a separate storage vessel. This process is essential when servicing refrigeration or air conditioning systems, as it permits the technician to safely remove refrigerant before repairs or maintenance on the unit.

Recovery differs from other processes like evacuation, which involves creating a vacuum within the system to eliminate air and moisture but not storing the refrigerant. Recycling involves processing the refrigerant to remove contaminants before it can be reused in the same system or another. Reclaiming refers to the process of purifying the refrigerant to industry standards for reuse, which typically involves more extensive treatment methods, thereby ensuring the refrigerant meets the necessary specifications for safe use.

By defining recovery properly, it clarifies its role in ensuring that refrigerants can be stored safely while minimizing environmental impact and adhering to regulatory requirements.
