HVAC Equipment For Handling GWP Refrigerants

There are several types of equipment that can recover low-GWP refrigerants, including recovery machines, vacuum pumps, and refrigerant analyzers. 

Recovery Machines are used to remove refrigerant from a system and store it in a tank for later disposal or reuse. Vacuum Pumps are used to evacuate air and moisture from a refrigeration system before charging it with refrigerant. Refrigerant analyzers are used to determine the purity of the refrigerant and detect any contaminants that may be present. 

It’s important to note that different types of low-GWP refrigerants may require different types of equipment for recovery. For example, hydrocarbons such as propane and isobutane require specialized equipment due to their flammability. It’s recommended to consult with a qualified technician or manufacturer to determine the appropriate equipment for a specific low-GWP refrigerant.

Refrigerant can be recycled. The process of recycling refrigerant involves removing the used refrigerant from the HVAC system and filtering it to remove impurities. Once filtered, the refrigerant is checked for purity to ensure that it meets the necessary standards.

There are several types of equipment available for recycling refrigerant, including recovery machines, vacuum pumps, and refrigerant analyzers. 

Reclaimed refrigerant needs to be AHRI certified to ensure that it meets the necessary purity standards and is safe for reuse in another MVAC system. The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) Standard 700 establishes the minimum requirements for the purity of recovered and reclaimed refrigerants.



The Environmental Protection Agency (EPA) requires that recovered refrigerant be sent to an EPA-certified reclamation facility to be purified according to AHRI Standard 700 before it can be resold for reuse in another MVAC system.

It’s important to note that different types of refrigerants may have different purity requirements. It’s recommended to consult with a qualified technician or manufacturer to determine the appropriate purity standards for a specific type of refrigerant.

What is HVAC Refrigerant Testing?

Image
HVAC refrigerant testing is a process used to evaluate the condition and purity of refrigerants that have been recovered in Heating, Ventilation, & Air Conditioning Industry. The purpose of refrigerant testing is to ensure that the refrigerant is free of moisture, acid, and particulate matter, which can damage HVAC equipment and compromise the system’s performance. Regular refrigerant testing is essential to ensure the safe and efficient operation of commercial and industrial HVAC systems. Contaminated or degraded refrigerants can lead to system failures, reduced performance, and increased energy consumption. For every 1% of contamination of the refrigerant the system loses 2% efficiency. Testing can also help identify leaks in the system, which can be a source of refrigerant loss and environmental damage. There are several companies that offer a quick turnaround service on refrigerant analysis, helping you to lower your maintenance costs and increase the lifetime of your system

A2L Refrigerant in Focus at ACCA "Next Level"

Image
REFRIGERATION A2L Refrigerant in Focus at ACCA "Next Level" Nov. 4, 2023 Experts described the points to consider regarding the HFC phasedown, the importance of refrigerant reclamation and an understanding of "mildly flammable" A2L refrigerant. Terry McIver Air Conditioning Contractors of America (ACCA) presented the “NEXT LEVEL” 2023 conference in Indianapolis October 16-17. Among the presentations to be featured in coming editions of Contracting Business and on ContractingBusiness.com was a panel discussion on the ramifications of the switch to mildly flammable, A2L refrigerants, as HFC refrigerants continue to be phased down over the remainder of this decade. Panelists were Don Gillis, technical trainer for A2L refrigerants, The Chemours Company; Kate Houghton, vice president, sales and marketing for Hudson Technologies; and John Maiorana, sales and product support manager, Arkema. What will A2L-friendly Equipment Look Like? Don Gillis “I don’t see a big change c
