R32 refrigerant is categorised as a A2L refrigerant. (A) meaning non-toxic, (2) meaning flammable and (L) meaning its flammability is low. Being classed as flammable can put a lot of people off from switching to an air conditioning system that use R32. But, its flammability is so low it only achieves ignition in highly controlled, laboratory conditions and even this is a slow low yielding reaction with combustion ceasing when the source of ignition is removed. In a real-life situation where you would be faced with a leak on a R32 system and you applied a naked flame, the reaction would be a small flame that would extinguish once the ignition source was removed.
As R410 has already began its faze out with its price fluctuating massively in the market, R32 is not just superior in its costing but its efficiency too. With a GWP of 675 compared to 2088 of R410A it has the advantage of appearing eco-friendlier compared to its predecessor. As for efficiency, R32 has 10% higher cooling capacity per unit of mass, meaning less refrigerant is required to achieve the same results as R410A
It recommended that you should seek to receive addition training with this refrigerant, even for the most experienced engineer. This not only helps to understand the risks but also the benefits. As always, a good product knowledge will help ease a client’s concerns and guide them to settle on a product best suited for their needs.
