  • Environmental effect of R22 vs R410A
    I was always very skeptical that R410A is any better for the environment than R22. In no particular order, here’s a few reasons why: 1. R410A has a significantly higher global warming potential than R22 does. It’s about 15% higher, not accounting for reason number 2. 2. Higher pressures mean more leaks. R410A operates at much higher pressures than R22, which means more chance of leaks. 3. More material required per unit. Since R410A runs at a higher pressure, AC units must be built with heavier duty components, which use more material to build. This may sound insignificant, but a couple extra pounds of copper per AC unit adds up. 4. Lower efficiency. I found a few studies showing that R410A often has worse performance than R22, especially in very high ambient temperatures. More energy consumption means more global warming. 5. Fractionation. R410A has the potential to fractionate, which would mean that the fractionated refrigerant would need to be destroyed rather than recycled. So which refrigerant do you think is better for the environment and why? Do you think I have a valid argument here?... Read more »
  • What exactly is a “nonflammable” refrigerant?
    So I got bored yesterday, so I decided to do my own flammability test of R134A refrigerant. Yes I know about the dangerous fumes produced. What I did is I set up my butane torch to stay lit, and I sprayed a small amount of R134A vapor on the flame. I was expecting it to blow the flame out, but to my surprise, the stuff burned! It didn’t support combustion, but it burned pretty well when the torch was held to it. So how could that be “non flammable”? I did some research, and I found on a few MSDS sheets that it can burn, but only under certain conditions, like high oxygen concentration or pressures above atmospheric pressure. So what exactly is the definition of a “non flammable” refrigerant? Does that just mean it won’t support combustion? And after seeing how well R134A burns even though classified as not flammable, it’s a bit scary to think about a “mildly flammable” refrigerant, like R1234YF. Not because I’m afraid of flammable refrigerants, but because it is labeled as “mildly flammable” when it is probably actually “highly flammable”.... Read more »
