Since R22 was a common refrigerant used in air conditioners, any decommissioned air conditions will likely have R22 recovered from them. The major one being that it does not have those o-zone layer-depleting chemicals. 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. 0000008920 00000 n Each manufacturer, including Koura and their Klea.

For this reason, the material has been gradually eliminated from the production process involved in creating new HVAC units. 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. If successful, your unit will become environmentally friendly and more efficient over the long term. If you do this, then it should be perfectly fine to load up with R410A. (2025 model year.)

As freon (also known as R-22) has been phased out during 2020, many homeowners are now asking themselves: Do you need to replace your home AC refrigerant? There, you are not even allowed to repair systems using R22 now. Some people do, but it is never going to be recommended. This field is for validation purposes and should be left unchanged. HFCs are intentionally-made fluorinated greenhouse gases used in the same applications where ozone-depleting substances have been used, including motor vehicle air conditioning. :68B6I"?uKF48R`r58j}s-Bjp :DOt=dDCq9gq?X{Z1VX#15-Tns)5o# U endstream endobj 324 0 obj <>stream In the United States, the U.S. Environmental Protection Agency (EPA) issued regulations under the Clean Air Act to phase out the One of the constant themes throughout the history of the HVAC industry is the search for a better refrigerant.
