After recovering liquid refrigerant from a centrifugal chiller, what is the next step?

The correct next step after recovering liquid refrigerant from a centrifugal chiller is to recover vapor. This step is essential to ensure that all refrigerant, both in liquid and gaseous form, is safely and completely removed from the chiller system before any maintenance or repair work is undertaken. Without recovering the vapor, there could still be residual refrigerant present in the system, which can pose safety risks, contribute to environmental harm, and violate regulatory requirements regarding refrigerant handling.

By fully recovering vapor, you ensure the system is clear and safe to work on, preventing any potential hazards associated with refrigerant exposure. This step is critical in adhering to best practices in refrigerant management and in compliance with environmental regulations.
