What does the term recovery refer to in refrigeration?

The term "recovery" in refrigeration specifically refers to the process of removing and storing refrigerant from an appliance. This process is critical in ensuring that refrigerants are managed properly during the servicing or disposal of refrigeration systems. Recovery is done to avoid releasing these substances into the atmosphere, which can be harmful to the environment and is often regulated by law.

This procedure typically involves using equipment designed to safely capture refrigerant, ensuring no leakage and that the substance is contained for proper recycling or disposal. The importance of recovery lies in adhering to environmental regulations and promoting responsible refrigerant management.

In this context, the other options hint toward different practices or methods related to refrigeration systems but do not accurately define recovery. For instance, recycling old appliances for parts pertains to decommissioning units, maintaining temperature relates to the operational aspect of systems, and replacing lost refrigerant deals with managing refrigerant levels, rather than the initial process of removal.
