R-32, A REPLACEMENT FOR R410A

What is the replacement for R-410A?

A lower GWP replacement for R-410A is Forane® R-32. Forane® 32 is a stand-alone third generation refrigerant for new residential and light commercial air conditioning systems, heat pumps and other HVAC applications.

Slightly flammable (A2L according to the ASHRAE 34), Forane® R-32 can be used in new equipment designed specifically for mildly flammable refrigerants as a suitable replacement for R-410A equipment. Its low density allows for option to use a smaller refrigerant charge. Consequently, there is a double advantage of Forane® R-32 versus other high-density solutions.

Unlike blended refrigerants, R-32 is a zero ozone depleting single component refrigerant: Difluoromethane. Using R-32 refrigerant is not only useful for direct emission reduction but also indirect impact on global warming. When using Forane® 32, equipment manufacturers reported an increase in system efficiency and seasonal energy efficiency ratio when compared to R-410A.
 

• Forane® 32 allows the use of the same existing component technologies developed for R-410A installations.
• Forane® 32 allows for the use of smaller compressor and heat exchanger versus R-22, which lowers manufacturing equipment cost.
• Forane® 32 equipment size is reduced versus R-22 equipment, which allows for easier handling and integration in the buildings.
• The GWP of Forane® 32 is 677 according to AR5, and the effective FORANE® 32 GWP is around 474.
• As a single component refrigerant Forane(R) 32 has zero glide and is easier to recycle at end of life.
