🔍 Key Concepts

• Refrigerant recovery cylinders: maximum safe fill (percentage of rated capacity) and why this limit exists • The purpose of a vent / vapor return hose between the chiller and the recovery drum in a liquid-pump ("push‑pull") arrangement • What parts of the chiller are protected from tube freeze‑up when liquid refrigerant is moved quickly to a drum

💭 Think About

• Look at where each hose is connected in the illustration. Which direction is liquid moving, and which path is for vapor or venting? • Ask yourself: in this setup, would any liquid or vapor still remain in the chiller after this step of the process, or would you still need an additional recovery step to meet legal requirements? • Consider safety: which statements would violate standard refrigerant‑handling practices for cylinder filling or for venting/isolating hoses?

✅ Before You Answer

• Verify the normal maximum fill percentage allowed for a refrigerant recovery drum and whether it is ever permissible to exceed it. • Decide whether a vent hose in a push‑pull recovery needs to be open or closed for refrigerant to flow properly and avoid over‑pressurizing the chiller or drum. • Determine whether this arrangement mainly helps with fast liquid removal from the chiller, with meeting final legal recovery levels, or with preventing tube freeze‑up.

Concerning the arrangement of equipment and associated hoses shown in the illustration, what statement is true? Illustration RA-0058

When recovering refrigerant from the centrifugal chiller using this method, it is permissible to exceed 90% of the weight capacity of the refrigerant drum.

When recovering refrigerant from the centrifugal chiller using this method, it is possible to achieve the recovery levels required by law without any further recovery.

When recovering refrigerant from the centrifugal chiller using this method, the vent hose connection should be closed.

When recovering refrigerant from the centrifugal chiller using this method, it minimizes the risk of chiller tube freeze-up.
