Honeywell and Parker partner to release refrigerant for ACs

Honeywell announced in 2019 a partnership with Parker Hannifin- Sporlan Division to distribute R446A. 

This is as momentum builds in the commercialisation of R466A, a non-flammable and lower global-warming-potential (GWP) refrigerant designed to replace R-410A in stationary air conditioning systems.

“We’ve completed material selection and extensive testing to optimise components for R446A applications in our evaluation of this refrigerant,” says Dustin Searcy, marketing manager, Sporlan Division. “These components have been found to optimise efficiency, capacity and reliability of the HVAC system. The benefits of R664A make it an attractive option for R410A replacement.”

Once commercially available, the refrigerant will be the first A1 non-flammable, lower GWP R410A replacement offered for stationary air conditioning systems. All other reduced-GWP alternatives proposed to date as R-410A replacements are flammable, potentially increasing risk to homeowners and contractors. R446A also offers a GWP that is 65% lower than R-410A. (A1 is the preliminary designation for ASHRAE.)

“R446A has undergone rigorous testing to ensure it can meet industry challenges and be compliant with regulations as a safe, energy efficient and environmentally preferable alternative to R410A,” says Chris LaPietra, vice president and general manager, Honeywell Stationary Refrigerants. “Our partnership with Parker demonstrates component readiness with this refrigerant as we transition later this year.”

R446A significantly reduces the need for additional design and eliminates the need to incorporate any sensors typically required for minimising flammability risk.

Early results also indicate this non-flammable, lower GWP alternative to R410A will eliminate the need for specialised contractor training for flammability mitigation – a big advantage for the industry as it struggles to recruit and retain certified contractors.
