Freon, also known as R-22 and HCFC-22, has been shown through repeated studies over the past few decades to be highly damaging to the ozone layer. %%EOF * The U.S. Environmental Protection Agency (EPA) recently released a new list of refrigerants to be delisted. At the most, it is going to cause you a little bit of pain. Contact with any part of your skin could result in frostbite, or at the very least, severe irritation. HCFC 22 -48% CFC 115 -52% : R503 CFC: No; banned under Montreal protocol: Low temperature refrigerant -80 to -100C. A refrigerant is one of the most important components of an air conditioning system. It is also an offence to manufacture or import refrigeration and air conditioning equipment . This means that if you find any R22, it will either have been produced before the phase-out or recovered from old, decommissioned air conditioners. Now, lets discuss what you need to do going forward if your unit is old enough to rely on freon to work correctly. The new delisted refrigerant list includes those used in new and retrofit equipment applications for food refrigeration equipment and vending machines, as well as new remote condensing equipment. xbbbc`b``3 n List of refrigerants Chemical refrigerants are assigned an R number (sometimes the label replaces it with the word Freon) which is determined systematically according to molecular structure. It isnt massively better, but in a widely used product, every little helps, right? Carrier vs. Lennox: Which Central AC Is Better? We'll explain its (important) role in your HVAC system. However, it needs to be operated at a far higher pressure than R22. HOC = Heat Of Combustion, Compounds used as refrigerants may be described using either the appropriate prefix above or with the prefixes "R-" or "Refrigerant." The hope is that having experts refill the air conditioner means that any leaks are spotted and patched up. Clarifications related to the terms used by the EPA to describe the end-use categories of the affected systems, as well as types of equipment that fall outside of the categories and end-uses mentioned in the ruling. R410A is a much more energy-efficient product. As of 2026 r-134a will be banned entirely for new vehicles. You have a couple of methods available to you. As you may well know, in the past, certain refrigerants were being phased out.

R-23 R-422A R-422D R-428A R-434A R-507A R-508A MO89 The overall goal of the Montreal Protocol and its amendments is to phase-out all ozone-depleting refrigerants, which has or will have occurred by 2020, and to eliminate the use of fluorocarbons (HFCs and PFCs) with a GWP of 2,500 or higher. Even then, were still talking about something that is not only destructive to the environment but is also going to eventually be more expensive than it would cost you to purchase a puron-based AC unit. While you shouldnt be mixing R22 with other refrigerants, some people mix them with one of the following: It is never really going to be ideal, but it may be able to help keep your system ticking over in the interim, i.e. 8/.u' 8H$U_7X C A'.=wHCc Canisters must be recyclable. We are bound by a common purpose: To Advance Life Around The World. It isnt as efficient, but the efficiency will sit somewhere between the 5% to 10% mark, so it will not be a significantissue. R410A refrigerant is not currently being phased out. Without it, the air conditioner wouldnt be able to cool down anything. The acceptable alternatives list is evaluated by the EPA and revised as necessary as alternatives become available for specific applications. The Montreal Protocol on Substances that Deplete the Ozone Layer. You may want to weigh the pros and cons of retrofitting an air conditioner against the pros and cons of just buying a new unit altogether. At the very least, they can determine whether or not your AC unit can be retrofitted in this fashion, to begin with. Under SNAP, all flammable refrigerants, except HFC-152a and HFO-1234yf, are listed as unacceptable for use in new and retrofit MVAC systems.

Opteon refrigerants feature zero ozone depletion potential and lower GWP values under AR4/AR5 than the HFCs they are designed to replace. While R-32 is still going to impact the environment, it is said that it only impacts the environment about a third as much as R410A, which certainl does make it a suitable replacement. The ozone layer lies approximately 15-40 kilometers (10-25 miles) above the Earth's surface, in the stratosphere. The ban is obligatory on both windows as well as split ACs containing refrigerants. Official websites use .gov Well, that is if it even works. The heat from the food in the refrigerator is then absorbed by the cool, liquid refrigerant. New and retrofit terms will be clarified regarding their relation to the servicing of existing equipment. The majority opinion is that HFO refrigerants are the future, and for automobile applications 1234YF will be the new go to. Therefore, nothing would happen. HFO-1234yf MVAC systems must adhere to all of the safety requirements of SAE J639 (adopted 2011), including requirements for a flammable refrigerant warning label, high-pressure compressor cutoff switch and pressure relief devices, and unique fittings. As long as you do not have any major leaks, then you should be fine. 0000047392 00000 n Almost thirty years after CFCs were outlawed, there is still a huge illegal trade providing refrigerants to the CFC systems still in place all over the world.
