The refrigeration and air conditioning industry is still in movement with a target to reduce the environmental impact. At the end of the 80’s we have been reducing emissions of ozone depleting gases like CFC’s, today we are banning all substances that contribute to an impact on the climate change and global warming.
Therefore there is worldwide growing interest in finding next-generation of refrigerants that does not harm the ozone layer nor contribute to global warming.
Producers of refrigerants developed a new class of mildly flammable refrigerant classified A2L with a result that they provide low Global Warming Potential and zero Ozone Depleting Potential.
Actually, there are several air-conditioning manufactoring companies announcing the introduction of air conditioning units running on the low GWP HFC refrigerant R32, designed to replace R410A in certain segments of the smaller and medium AC units.
What is important to know that R32 is a single component, zero ODP gas with a GWP of around 650.
Characteristics: R32 is difluoromethane (methylene fluoride) and it is an HFC type of refrigerant. R32 has been used for many years as a component of both R407C and R410A. It is flammable on its own, but not when mixed with the other components of these blends.
