When a refrigerant is listed as unacceptable, its use is illegal. This means that leaking R410A is hugely dangerous to the environment. However, it is suggested that if you do use an air conditioner that runs on R22, you should probably consider replacing it soon, or at least upgrading it to accept R410A refrigerant. OEMs must keep records of the tests performed for a minimum period of three years demonstrating that CO2 refrigerant levels 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 breathing zone. 2023 HVAC.com a Magenta Technologies LLC Company, All Rights Reserved, Energy tax credits 2023 for home improvement projects, https://www.hvac.com/resources/energy-tax-credits-2023-home-improvements/, What is an air handler? 0000151387 00000 n Read more Read less Read the detailed overview made for the main regulations including the Montreal Protocol , the EU F-gas regulation , and the US SNAP regulation , which was turned down .
