Best channel on youtube for explanations!

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

[@microcolonel]

Beautiful. Congratulations to the engineers and researchers at Danfoss on getting this to market.

[@CheiithooCat]

Best hvac channel ever.... thanks

[@DWAYNE2ism]

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.

[@FractureLimit47]

Best engineer channel Helped me a lot with the hvac systems.

[@paulgaras2606]

Every time I watch a video on this channel I feel like an expert.

[@santhoshsanthu18]

Berry helpful video. Please upload a video about transducers

[@thefamilycat86]

Very good explaination!

[@asisiphogobingca8000]

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.

[@azhariboerhan3402]

Thank you for the Ejector information. Can it working at tropical regions ?

[@palamidi13]

excellent video!

[@mirzanahida1181]

Besttttttttt explanation ever!!!!!!Paul be my teacher

[@tylerhvacrtekk4247]

Your channel is literally HVACR porn. Absolutely love it! 👍keep up the great work!

[@shashankambiga6106]

Plz explain about pressure transdusers

[@balajichandrasekaran6312]

@5:57 i am confused with % flow?

[@micahcoons7632]

I was thinking the same thing

[@mikefreedom5612]

He has a mistake of %

[@1freebird326]

It should be 40% to the parallel compressor in the last diagram.

[@sparc5]

Why is this only used for commercial refrigeration and not home air conditioners?

[@randomrefrigeration4564]

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

[@RSBot2jar]

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.

[@kdote7038]

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.

[@RSBot2jar]

@@kdote7038 I was talking about the discharge line. Still got no answer to this day.

[@kaustubhsawantdesai7586]

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)...

[@EngineeringMindset]

please see our other videos

[@jamesortolano3983]

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?

[@alexandriap.3285]

Uh... the title currently reads "priciple"; did you mean "principle"?

[@alexandriap.3285]

Good video, tho! ^.^

[@TheManolis1984]

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.

[@cl8ff]

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.

[@3PhaseAC]

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.

[@EngineeringMindset]

From the one side angle you can't tell the thickness of a each gear and if they're touching or not.

[@3PhaseAC]

@@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.

[@ICANanimations]

wait wait, I thought CO2 made things warmer... 🤔

[@miamisasquatch]

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...

[@HamguyBacon]

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