Understanding Refrigerant Management Processes

What does the process of "recovery" involve in the context of refrigerants?

• Cleaning refrigerant for reuse in equipment of the same owner.

• Removing refrigerant from a system and storing it in an approved container.

• Processing refrigerant to a level equal to new product specifications.

• Adding odorants to refrigerants for safety.

Which of the following is true about recycled refrigerant?

• It can be sold to any owner.

• It must meet AHRI 700 Standards before use.

• It is cleaned using oil separation and filter-driers.

• It is processed to a level equal to new product specifications.

What is the purpose of reclaiming refrigerant?

• To remove refrigerant from a system and store it.

• To clean refrigerant for reuse without meeting all reclamation requirements.

• To process refrigerant to a level equal to new product specifications.

• To add odorants to refrigerants for safety.

What is required for refrigerant recovery and/or recycling equipment manufactured after November 15, 1993?

• It must be able to add odorants to refrigerants.

• It must be certified and labeled by an EPA-approved equipment testing organization.

• It must be able to process refrigerant to a level equal to new product specifications.

• It must be able to clean refrigerant using oil separation and filter-driers.

Which type of recovery device uses components in the appliance to capture refrigerant?

• Self-contained (active)

• System-dependent (passive)

• Reclaiming device

• Recycling device

Why should long and small diameter hoses be avoided during refrigerant recovery?

• They increase the risk of refrigerant contamination.

• They cause excessive pressure drop and increase recovery time.

• They are not compatible with EPA-approved equipment.

• They can only be used with self-contained recovery devices.

What should a technician do if servicing systems that use different types of refrigerants?

• Use the same recovery cylinder for all refrigerants.

• Mix refrigerants in the same container.

• Have a separate recovery cylinder for each type of refrigerant.

• Only recover refrigerants that meet AHRI 700 Standards.

What is the most effective method to determine the general area of a small refrigerant leak?

• Using soap bubbles.

• Pressurizing the system with dry-nitrogen.

• Using an electronic or ultrasonic leak detector.

• Adding odorants to the refrigerant.

What is the purpose of dehydrating a refrigeration system?

• To add moisture to the system.

• To remove water and water vapor.

• To increase the system's pressure.

• To add odorants to the refrigerant.

What indicates that dehydration of a refrigeration system is complete?

• The vacuum gauge shows a pressure of 1000 microns.

• The system holds a vacuum of 500 microns or less.

• The pressure steadily rises after evacuation.

• The system is pressurized with dry-nitrogen.
