Hey Guys,

I'm doing some research with regards to R290 and I've noticed that it helps increase the efficiency of AC systems. I'm trying to find articles or information with regards to this. Does anyone know where I could possibly find information about better efficiency performance of R290?

Thanks in advance.

They claim 10% savings.
In a practical system, R290 is better than R410a or R22.

I actually have a system that's running a R290 based mix in a R410a compressor (the "Davuluri Treatment"). The compressor runs much quieter and draws much less power than it did with R410a, but it's not a direct comparison since many other parts of the system were changed.
