[March 8, 2017] - Daikin Industries, Ltd., the world's leading air conditioner and refrigerant manufacturer based in Osaka, Japan, announced today launch of R-407H refrigerant, which has approximately 62%*1 lower global warming potential (GWP) than commonly used R-404A refrigerant today.

Currently, R-404A, a high GWP refrigerant is widely used in refrigeration equipment in supermarket, warehouse, and marine vessel applications. Many international regulations are in place or planned to limit the GWP of gases used in refrigeration systems, for example:

•  Japan's Act on Rational Use and Proper Management of Fluorocarbons set a target date of 2025 to achieve a market volume weighted average GWP less than 1500 for Condensing Unit and Refrigerating Unit*2,

•  the European Union's revised F-gas regulation*3 prohibits refrigerants with GWP 2500 or more for Stationary Refrigeration Equipment,

•  the US Environmental Protection Agency (EPA) has listed R-404A as unacceptable by 2020 for Retail Food Refrigeration and Vending Machines, and 2023 for new cold storage warehouse in their Significant New Alternatives Policy (SNAP) program*4.

With increasing regulation on HFCs, there is greater demand for refrigerants that are safe to use, energy efficient, allow for easy and economical conversion and can comply with the various regulations around the globe.

Daikin has developed a non-ozone depleting, lower GWP, and non-flammable refrigerant R-407H (GWP 1495). Compared to R-404A which is commonly used today, R-407H has a 62% lower GWP, and based on testing conducted by various equipment manufacturers and university, it had shown as equivalent in low temperature, and improvement in medium temperature in efficiency (COP)*5. In addition, R-407H has similar working pressure to R-404A and can be considered as an alternative to achieve an economical retrofit with limited modifications.

Daikin will offer R-407H as a replacement for R-404A refrigeration systems, but also has an extensive development program to bring even lower GWP refrigerants to the cooling and heating industry.

R-407H Refrigerant Classification
R-407H is a non-ozone depleting refrigerant with a GWP of 1495, and has been classified by ASHRAE as same safety group as R-404A, "A1: lower toxicity, no flame propagation refrigerant".

Daikin's Refrigerant Policy
Daikin has a long history of continually reducing the environmental impact of cooling, heating and refrigeration products, as well as having a unique expertise that comes from manufacturing both refrigerants and equipment. This position is a result of the company's corporate philosophy to "Be a Company that Leads in Applying Environmentally Friendly Practices".
Regarding refrigerant choice, Daikin has expertise in using fluorinated (HFC, HFO) as well as non-fluorinated gases (ammonia, carbon dioxide, hydrocarbons), because the company believes in diversity of refrigerant choice to allow the best suited solution to be used in each application.
