Further restrictions on class 3 flammable refrigerants include confirmation of a ban on their use as a retrofit refrigerants in residential and light commercial AC and heat pumps unitary split. This is because it is far better at being able to pull the heat out of the air. R-22 has been proven repeatedly to be a significant cause of damage to the ozone layer. 0000047669 00000 n If you own an air conditioner manufactured before 2010, you may notice that it uses a refrigerant known as R22. 0000033592 00000 n 0000134472 00000 n It would have evaporated long before it hits your mouth. Check which refrigerant your equipment uses. The HFO refrigerant R1234yf, designed as a replacement for R134a in car air conditioning systems, is extended for use in newly manufactured medium-duty passenger vehicles, heavy-duty pickup trucks, and complete HD vans. However, it needs to be operated at a far higher pressure than R22. If you purchase an air conditioner nowadays, it is likely to use a refrigerant known as R410A. (2025 model year.) 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. HVACR refrigerants that have been delisted include: Retrofitted supermarket systems: R-404A, R-407B, R-421B, R-422A, R- 422C, R-422D, R-428A, R-434A, and R-507A as of July 20, 2016 New supermarket systems: HFC- 227ea, R-404A, R-407B, R-421B, R- 422A, R-422C, R-422D, R-428A, R- 434A, and R-507A as of January 1, 2017 While R410A can be dangerous, it does not impact the ozone layer in the same way R22 does. The good news is that the answers to these questions are pretty straightforward. The refrigerant accomplishes this by cycling between being a gas and a liquid. The gases affected are the higher Global Warming Potential (GWP) HFCs and the higher GWP blends, originally designed as interim retrofit gases. Servicing of existing vehicles using HFC-134a with HFC-134a will not be impacted and will continue to be allowed. This includes all hydrocarbon refrigerants. Acceptable, subject to use conditions, for new vehicles only (June 6, 2012, 77 FR 33315), Operates at 5 to 10 times higher pressure than other MVAC systems, Under development by several foreign automobile manufacturers, Exempt from the Section 608 venting prohibition, meaning it is legal to knowingly release this refrigerant to the environment; however, CO. Engineering strategies and/or mitigation devices shall be incorporated such that in the event of refrigerant leaks the resulting CO2 concentrations do not exceed the STEL of 30,000 ppm averaged over 15 minutes in the passenger free space and the ceiling limit of 40,000 ppm in the passenger breathing zone.
