CAN YOU USE R-134A IN A R-290 SYSTEM?

  My co-workers Father was a one man show refrigeration man on the Oregon Coast. On cap tube R-22 freezers he would cut 6" off the cap tube and drop in R-12. Compressor amp draw went down, this guy saw the same customers ( many were commercial). He saw many of these units live a long happy life. This was done in the 1970's.

  As a risk taking tinkerer, i have discovers that bbq grade 290 works pretty damn good in a 134a system.

  Thank you for doing this. I was really curious about these two refrigerants being interchangeable. This is very educational and worth watching.

  Liked it without even watching it, trying to change r290 with 134 was my idea for a long time.

  You experiment was well worth it the time to watch, I am not a refrigerant coolant designer but the first thing that came to mind was the word densities, more targeted the density of Gas.  The two gases and their properties are totally different and as Mike H said it, R134A has a finite window for working or not working.  it is like a ham radio operator trying to adjust its HF antenna to talk to Cubans. Anyway so greatful for this channel and youtube as a means to help each other out.   I  found that after 15 years, my copeland compressor went bad and was not because of any body mixing any gases and not purging the old ones out. It went out due to moisture. One of the pipes in the inverter went out and the system kept running for some reason until the low level tripped it off. Then moisture and its age, i believe it had been been there since the 90s overheated and there it went. When I cut it open it had black oil and the compressor on the outside was black as in black ash or dirt and then I learned that mixing R134a and R410a can do that.

  Chris, this is a spot on video....this is exactly the proof that you cant just use any system with any refrigerant....systems are specifically designed for use with certain temps, pressures, and efficiency. I've had moronic ideas early in my education to use the wrong refrigerant when the easy way looks soooo good. Thank you for the real word application and hopefully you've helped another "super tech" from a badd mistake....J
