Forane® 32

Product
Room Air Conditioning

Forane® 32 is the main component of R-410A refrigerant. Mixed with the R-125 fluid, Forane® 32 is behind the high efficiency of Forane® 410A.

 

In order to offer a lower GWP refrigerant as a replacement for R-410A and to reduce its direct emission impact on global warming, Arkema is promoting Forane® 32 as a stand-alone refrigerant for air conditioning and heat pump applications. Experiences and feedback from OEMs worldwide show that Forane® 32 is an excellent candidate for these applications.

Forane® 32 is a pure component refrigerant with a GWP of 677 according to AR5

 

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

 

Equipment manufacturers reported 30% refrigerant charge reduction. Meaning, the CO2 equivalent refrigerant charge for a 1kg R-410A installation will be:

  • For Forane® 32: 1kg x 70% x 677 = 474 kg equivalent CO2
  • For R-410A: 1kg x 2100 = 2100 kg equivalent CO2

 

Therefore, the use of Forane® 32 instead of R-410A shows a reduction of more than 80% of the direct emission impact on global warming.

 

Effective Forane® 32 GWP is 474

 

Applications

Forane® 32 can be used for cooling (left hand) or heating (right hand) applications, as shown in the graph below.

 

In order to be used for different applications, compressor manufacturers developed special compressor types for R-32 refrigerant. Some compressors are equipped with a special cooling system as liquid or vapor injection, in order to increase the compressor’s envelop to high condensing temperatures.

 

Forane® 32 can be used for all types of air conditioning technologies, including heat pumps and water heaters. You can also find refrigeration equipment using Forane® 32 refrigerant in the market.

 

Benefits

Forane® 32 is a high pressure, fluorinated refrigerant. Using R-32 refrigerant is not only useful for direct emission reduction but also indirect impact on the global warming.

  1. When using Forane® 32, equipment manufacturers reported an increase in system efficiency and seasonal energy efficiency ratio.
  2. Forane® 32 allows the use of the same existing component technologies developed for R-410A installations.
  3. Forane® 32 allows for the use of smaller compressor and heat exchanger versus R-22, which lowers manufacturing equipment cost.
  4. Forane® 32 equipment size is reduced versus R-22 equipment, which allows for easier handling and integration in the buildings.
  5. The GWP of Forane® 32 is 677 according to AR5, and the effective FORANE® 32 GWP is around 474.
  6. As a single component refrigerant Forane(R) 32 has zero glide and is easier to recycle at end of life.
