Wholesale Environment Friendly refrigerant gas R32 for Replacing R410A

R32, better known as difluoromethane, is an organic gas, much like R410A. With an ODP of 0, the two gases are also equally harmless to the ozone layer.

Still, R32 has a GWP of 675, which is significantly lower than those of R22 and R410A. That makes it a seemingly better alternative.

R32 performs well in terms of pressure drop and heat transfer. It’s a grade A2 gas, which means it is mildly flammable.

In spite of that, R32 has been successfully used for many years now, most notably in China, India, and Japan.

In order to mitigate the risk related to its flammability, experts recommend using heat transfer equipment that has a low refrigerant charge.

Interestingly enough, R32 is a component found in other refrigerants. For example, by combining it with R125 and R143a, we can create refrigerants R407A and R407B.
