Great video learn a lot. Here in the Caribbean I always worry about the critical temperature point of refrigerants and their ability to change phase. In high ambient applications.
Can you create a video on package ac about 16TR or more bigger capacity....its designing also working. Package ac connected with duct system(Air cooled system) and closed water system(water cooled system)...
I was wondering about the following; I have my compressor going from, let's say, 35 bar to 100 bar. Is the CO2 leaving the compressor instantly a supercritical fluid? If you would look at the P-T diagram, then you would say yes, but it's kinda weird to wrap your head around.
Are you getting you “‘100 bar leaving the compressor’” from the liquid line or discharge line? I am no co2 technician. Just a curious traditional refrigeration technician.
Cost CO2 systems are extremely expensive due to the high pressures all copper has to be thicker walled and the valves extra heavy duty So cost would be your answer
So 4,6 injectors are available are the all feeding the receive?3 other ports are not discussed they feed the evaporator s? Very impressed with this liquid inertia inertia system. New to me I feel I can comprend if I just had more time with, nd found out about three remaining ports . Thanks so much to danfloss😉,nd your video. Can you elaborate some more?
Great video as always. I only have one objection. At the beginning you mention that CO2 is non-toxic, however at 10% concentration it can be lethal (one of the reasons that using a CO2 fire extinguisher in confined spaces is not a good idea) while OSHA's guidelines say that 3% is the maximum concentration in workspaces. How are systems using CO2 protected against potential leaks. Is there a a safety requirement for CO2 detectors or ventilation where CO2 systems are present? It does have great potential though as a refrigerant.
technically speaking, most refrigerants in use these days are non toxic(they can contribute to global warming if released into the atmosphere) . however, they are heavier than air. so they could collect on along the floor of a basement. thus displacing the oxygen. a person would suffocate without oxygen.
So I like your videos and what you do, but i have one small problem that an engineer should spot. The gears in your logo will not turn sice you have 3 gears touching... I don't know if that's on purpose or if it's a special functional gear set that I haven't seen.
GWP of 1 is defined as the Global Warming Potential of C02, it's not great, but considering current refrigerants in use exceed a GWP of 1400 (1400x worse than C02) it's a MUCH better solution... and less killy than Ammonia when it accidentally gets released...

Current HVAC Intern here. Great videos! Really helping me to understand all the basics. You should do a video about zoning!

Beautiful. Congratulations to the engineers and researchers at Danfoss on getting this to market.
Best hvac channel ever.... thanks
Best engineer channel
Helped me a lot with the hvac systems.
Berry helpful video.
Please upload a video about transducers
Every time I watch a video on this channel I feel like an expert.
Your channel is literally HVACR porn. Absolutely love it! 👍keep up the great work!
Plz explain about pressure transdusers
Very good explaination!
Besttttttttt explanation ever!!!!!!Paul be my teacher
excellent video!
@5:57 i am confused with % flow?
I was thinking the same thing
He has a mistake of %
Very informative, thank you. Do you have a video that you can refer me to with a de-superheater unit on the system. Thank you in advance.
It should be 40% to the parallel compressor in the last diagram.
Thank you for the Ejector information. Can it working at tropical regions ?

@@kdote7038 I was talking about the discharge line. Still got no answer to this day.
Why is this only used for commercial refrigeration and not home air conditioners?

Uh... the title currently reads "priciple"; did you mean "principle"?
Good video, tho! ^.^

From the one side angle you can't tell the thickness of a each gear and if they're touching or not.
@@EngineeringMindset ahh i was trying to blow up the image, but I couldn't see the teeth of each gear. I'm glad you wrote me back.
wait wait, I thought CO2 made things warmer... 🤔

@@miamisasquatch the lie and scam that co2 causes climate change can be rebuked by basic 4th grade science of the carbon cycle.
