What type of equipment captures refrigerant into a non-pressurized container?

• A. Active recovery equipment
• B. System dependent or passive recovery equipment
• C. Refrigerant compressors
• D. Vacuum pumps

Answer: (B)

For capturing refrigerant into a non-pressurized container, system dependent or passive recovery equipment is the correct choice because this method involves using the existing pressure within the refrigeration system to help move the refrigerant into a recovery cylinder. This type of equipment does not require an external power source to remove the refrigerant; instead, it relies on the system's own pressure, making it ideal for non-pressurized storage.

This method is valuable when the refrigerant is not in a high-pressure condition, allowing it to flow into the recovery container naturally. Passive recovery is generally simpler and safer, as it does not involve active mechanical systems that might introduce complications or additional risks during the recovery process.

Active recovery equipment, on the other hand, mechanically pulls refrigerant from the system into the recovery container by using a pump, which is not how a non-pressurized collection is achieved. Refrigerant compressors and vacuum pumps serve different purposes in refrigerant systems; compressors are used to circulate and pressurize refrigerant, while vacuum pumps are employed to remove air and moisture from the system but not to capture refrigerant into a non-pressurized state.
