The refrigerant that the refrigerator uses is R12, R22, R32, and R410. So, just using r134a will be favorable. … Is it legal to sell R-12 refrigerant? Yes, you can still sell R-12 and other CFC refrigerants. Although these refrigerants can no longer be manufactured, it is perfectly legal to sell to an EPA certified buyer. R22 and R410A refrigerants with higher GWP values have more direct GHG emissions, and refrigerant leakage during the recovery phase is the most important source of emissions. R32, R161 and R290 refrigerants, which are used as alternatives in the future, have relatively good performance in terms of GHG emissions. This approach can save some money, if the indoor components are still in good shape and you can find the R-22 outdoor replacement parts along with the R-22 refrigerant. Many people have decided to do this and many contractors support this approach. We think this repair will continue to be a viable, low cost repair option, at least through 2016 Systems with a low-GWP refrigerant can therefore have a larger charge than those with a higher GWP. R410A is a 50/50 mixture of R125 and R32. However, R410A has a GWP of 2088, compared to just 675 for R32. Daikin’s approach is to replace R410A with R32, along with a number of other companies. 42671 posts · Joined 2008. #6 · May 27, 2009. I find that R410A often uses either the same size vapot line, or sometimes a smaller vapor line. While R410A (1250FPM) on vertical risers does have a higher min vapor velocity for oil return then R22 (1000FPM). If the compressor is below the evap, it is not a concern. It has a higher cooling capacity than R22, allowing for more efficient and effective cooling. R407C is another popular R22 alternative that has similar thermodynamic properties to R22 and can be used in many existing systems with minimal modifications. Other refrigerants such as R32, R438A, and R422D have also been developed as alternatives to R22. In this video, we're explaining what is 410A refrigerant , how it's different and why it's becoming the R22 refrigerant replacement. You'll also learn how to MHAQUm.

can i replace r22 with r32
