Given the recent ruling from the EPA, CO2 is probably a foregone conclusion for us where I live in the US, but one of the biggest issues I have with it is that there is so much more complexity required to make it work in hot, humid environments. While I'm not saying that all forms of complexity are bad, Lindbergh's rule still holds. How reliable are these extra devices? How easy are they to fix or replace when they malfunction? How often do they cause other catastrophic failures in the system when they fail?
Valid concerns this is why commercial refrigeration training is going to be more important than ever before. We have many CO2 refrigeration technical training programs at www.refrigerationmentor.com from basic fundamentals to advanced troubleshooting CO2 systems. Thanks for sharing.
Trevor, I have an unrelated question to this video yo ask you. When my 2 ton 8yr old single stage goodman scroll shuts off occasionally, the vanes sometimes sounds like marbles rattling for a split second until the vanves come to a stop. So the question is at the moment the compressor stops at high side operating pressure, why is that high side pressure at shut down making the vanes momentarily sound like marbles happening until it comes to a complete stop. The system cools and I've noticed this occasional sound at shut off for yrs. The condenser coil and filters are clear and both indoor and outdoor fans are working properly. Thank You
From what I am understanding with your question is that when the compressor satisfies and shuts off it make a noise and only at those times. If this is so what it could be is that the Scroll is spinning backwards on shut down. This could potentially be that the anti rotation device has something stuck in it or it has been damaged in someway. The compressor should still work fine but will be annoying during shut downs. Unless you have it inspected properly its hard to tell.
Thanks for getting back to me, so because I can only hear and not see what your saying, is the anti rotation devise something that can be a intermittent not being in the exact position rulet wheel. Because you know from taking 100's apart, is there a discription and drawing some where that shows these subtleties of scrolls, is the anti rotation devise something that is spring loaded to immediately step in at shut down, what can react that fast to prevent the high side pressure from rotating the vanes backwards on shut off occasionally like I described. Thank you Trevor
@@charlessolazzojr6767 there are many different types of anti rotation devices. It all depends on the model of the compressor. You will have to looking up the drawings on OPI at www. climate.emerson.com or contact Copeland they should help.
Thanks for getting back to me with that information to look up questions, and get answers from that contact information, thanks Trevor. I know your putting tons of info out on CO2, but I'm seeing a ton of VRV being pushed on utube in parallel with Co2 systems, you know they are software and algorithm driven systems. There pushing there 10X heat transfer
More design videos Trevor! This was great, thank you.
You are very welcome!
i have been looking for the simple tool that you provided for 3 years you may of just helped save the world
We do what we can. Let us know how it goes.

Hey Trevor. I love the cap you're wearing. Cool!
Thank you da we
Thank you Trevor you are doing a great Job.
I appreciate you Toyin. Thank you for your support.
Definitely some good information.
I think so. I listened to it a 2nd time and its a conversation where you have to take notes because there are so many great points.
Good one 👌
I gained so much knowledge from this session it was awesome.
So can i ask if you are in asia summer all year round, using co2: energy consumption is high?
Great question: It depends on your location as asia is a massive country. If its designed properly no. www.refrigerationmentor.com
Hello Trevor Sir,
Can you please make video on insulation testing for hermetic and semi hermetic compressors?
I think that is something that can be done.

Trevor, I don't know if you seen my follow up question to your reply about my scroll compressor occasionally spinning backwards on shut down.
