Under what condition may recovered refrigerant be reused?

The condition under which recovered refrigerant may be reused is when it is used in the equipment it was removed from. This is because refrigerants may pick up contaminants while in the system, and reusing them in that same system minimizes the risk of introducing contaminants into different equipment or systems that may have stricter purity requirements.

While refrigerants can indeed be recycled or purified to meet specific standards, these actions generally apply to broader contexts rather than simply reusing the refrigerant in the original equipment. The regulations and best practices dictate that when refrigerants are recovered, they should ideally be reused in the same system to mitigate any potential risk of contamination or performance issues that might arise from using refrigerant in systems that may not be compatible with it.

This approach helps in maintaining the efficiency of the HVAC system while adhering to environmental regulations around refrigerant management.
