If you’ve recently started researching a new air conditioner for your South Florida home, you may have run across “R410A” – a newer form of refrigerant increasingly being used in high end air conditioning equipment. What is R410A and why is it different from the existing refrigerant most air conditioners have?
R-410A is a composite of diflouromethane and pentafluoromethane. This mixture of R-32 and R-125 creates a new compound designed to be used in commercial and residential air conditioning devices. Sometimes referred to as Puron, Genetron and EcoFluor, R-410A is a more environmentally friendly approach to cooling than the existing coolant most air conditioners use – R-22.
To date, R-22 has been the refrigerant of choice for millions of devices. However, because R-22 will no longer be permitted in new devices starting in 2020, R-410A is growing in popularity rapidly and will soon become the standard refrigerant option in new devices.
Despite being very similar in chemical composition to other refrigerants like Freon and R-22, R-410A does not contribute to ozone depletion, a major step forward for air conditioning. However, it has as very similar global warming impact – producing nearly 1725% more damage than carbon dioxide. One of the factors that negates this high global warming risk is the fact that R-410A is being used in a more efficient manner than past refrigerants.
You cannot simply replace the R-22 in your South Florida air conditioning system with R-410A. Because it requires higher pressure, the devices that run with R-410A must be built specifically for this refrigerant. As a result, many manufacturers are starting the transition to the new refrigerant now, in anticipation of the 2020 phase out date for R-22. If you are preparing to buy a new unit, keep this in mind.
