Daikin Adopts R-32 for Key HVAC Products in North America

Oct. 30, 2019
R-32 can mitigate effects of direct refrigerant emissions by reducing the equipment refrigerant charge in certain equipment by up to 40 percent.

HVAC manufacturer Daikin’s companies in North America (Goodman Global Group, Daikin North America, Daikin Applied Americas, Daikin America and Daikin U.S. Corp.) announced they are developing ducted and ductless residential, light-commercial and applied products utilizing R-32 refrigerant

In evaluating alternative, low global-warming-potential (GWP) refrigerants for North America, Daikin is focused on reducing greenhouse gas emissions and climate impacts. The company also took a holistic approach to include safety, energy efficiency and cost-effectiveness. Based on comprehensive evaluation and testing, Daikin concluded R-32 is the ideal low-GWP alternative to R-410A for many key residential, light-commercial, and applied products in North America.

Daikin’s choice of R-32 is based on the beneficial attributes of the refrigerant. Compared to R-410A and certain alternative refrigerants, R-32 can mitigate the effects of direct refrigerant emissions by reducing the equipment refrigerant charge in certain equipment by up to 40 percent. The company also found that equipment using R-32 can be more energy-efficient and compact — thereby consuming fewer manufacturing resources — when compared to equipment using R-410A or certain alternative refrigerants.

The manufacturer believes that R-32 — a pure, single-component refrigerant available globally from multiple suppliers — is easier to reuse, reclaim and recycle when compared to other refrigerants that are blends of R-32 and other components.

The choice of R-32 for the North American region is consistent with the wide global acceptance of the refrigerant. In Japan, R-32 is the dominant refrigerant for residential HVAC equipment while in other Asian countries — including China — and in many European countries, the refrigerant has become an increasing popular choice for HVAC equipment. Daikin has estimated that more than 84 million R-32 residential units have been installed by the industry across 70 countries.

Furthermore, in the United States, acceptance of the refrigerant has already begun in some HVAC applications.

To advance the adoption of R-32, Daikin has committed to share its knowledge and expertise. Earlier this year, Daikin announced its patent non-assertion pledge of identified patents to further facilitate the use of the R-32 in HVAC products. The company also provided education and training programs for the refrigerant.

“We know that the net effect of air conditioning on the environment is a combination of the refrigerant used and energy consumed,” said Daikin Applied Americas’ President and CEO Mike Schwartz. “R-32 enables home and building owners to achieve reduced climate impact, superior performance and operational savings. Daikin is in a unique position as a manufacturer of both HVAC equipment and refrigerants. Our approach has always been to use our expertise to choose the right refrigerant for each application. R-32 is the right low-GWP refrigerant choice for many of our residential, light-commercial and applied products in North America.”

Goodman Global’s President and CEO Satoru Akama said: “Daikin’s choice of R-32 demonstrates our strong commitment as a U.S. HVAC manufacturer to minimize environmental impacts of our equipment, including the reduction of greenhouse gas emissions. R-32 brings many benefits, including energy efficiency, resource reduction and overall environmental mitigation. Based on our global experience, we are confident R-32 is the right choice for HVAC manufacturers, contractors, and consumers.”

Daikin’s North American production of R-32 products is the latest step in its efforts to advance technologies that reduce environmental impact and provide consumers superior technology. These efforts will take account of the developments in various North American jurisdictions as they enact appropriate regulations, codes and standards.
