Re: R410A I apologize for the confusion. R134A is not a drop in replacement for R22. R410A isn't either. R407C is as close as it gets. Many manufacturers using R22 redesigned and then switched to R134A to avoid higher costs. My window unit runs R134A (8 years old). My central air runs R134A (6 years old).
HFO-1234yf (a flammable substance) will be replacing R134A in new automotive and other mobile A/C systems. Europe first, then North America. The systems are under much higher pressure. |

 Comp output Pressure (Red is 1234yf - click for full size)
The real wild one is R-744 (CO2). It runs at pressures between 5 to 10 times higher than R134. -- Striving for Parfection. |

It runs at pressures between 5 to 10 times higher than R134. That's good! Shouldn't cause any more leaks into the atmosphere. Sounds like a sound well thought out plan.  |
