*Correction* @7:53 Condition 2 Atm is < -10°C which is said correct but displayed wrong.

Excellent video, this is by far the best explanation out there.

This is the best explanation of the octovalve I've come across. Great graphics. Thank you very much.

This is by far the best heat pump explanation that I’ve ever seen. Thanks for creating this series.

This is so brilliantly done! Amazing how such a complicated system has been broken down and explained. Fantastic work.

these series videos are awesome, helps me learn a lot about Tesla thermal management, I just want to express my great gratitude to all the contributor, thank you so much Untangle Club.

thats the best explanation on the internet

No one explained this , but you did this..GREAT JOB THANKS!

ผมเป็นครูช่างยนต์ชาวไทย ผมได้ความรู้ความเข้าใจระบบการจัดการความร้อนของเทสล่าจากคลิปวีดีโอ และจะนำความรู้เหล่านี้ไปสอนนักศึกษาของฉัน ขอบคุณมากๆครับ

Really excellent video dude! You should get a job at Tesla.

Great video and animation. When you see a Munro comparison of Tesla vs Mustang, you really get a sense of how much further ahead are the engineers at Tesla. Why is this true? The answer is that Tesla is a company run by engineers, while other automakers are companies run (into the ground) by accountants, MBAs, and HR twits.

Amazing thank you! No one else has come close to explaining what this hallowed octovalve actually does and I've been searching for months. Thank you KZfaq algorithm for randomly showing me this and thank you Untangle Club for putting so much work into this explanation. (PS. Your English is amazing but your accent is very hard to understand. This isn't a criticism, just something I hope helps you because, as someone learning a foreign language, I appreciate it when people help me out with comments like this)

I was afraid it's gonna be another hype video but damn that was great explanation

Got my octavalve tee shirt from Sandy.

I saw this on reddit Tesla investor club

This is an incredible explanation, so clear, of such a complex system. Thank you!

Best explanation so far found. I was thinking that you will go through all of the 15 cycles.

Still learning a lot, so much information that you have to see it several times. Thanks

Amazing. Liked, subscribed and shared

Amazing video. Thanks, sir!

Putting “No Clickbait” on the teaser image is EXACTLY what a clickbait video would do 😂

nice done!

Great work. 👏👏👏

Excellent video! Thank you for creating thermal management series.

Needs to improve clarity : 1) Having both refrigerant AND coolant is confusing, they should be labelled on the image. 2) Refrigerant should be dotted too in the chiller and LCC. 3) Dead end paths clutter the view, they should render differently (dimmed ?). 4) Flow direction is vital and should be rendered.

Excellent explanation thank you.

Such a complex system explained by you in a detailed and easy manner.. This actually needs a hell lot of efforts... Thanks a lot for efforts..this is just splendid explanation

Keep making such informative video

Great video!

Sir this is a fantastic explanation, thank you for the wonderful explanation

Hi, yes good job. very fine explanation and graphics. Thank you.

Thank you so much! Superinteresting and even if I don't get all the details, I now understand the concept. Excellent job! 👏🏼

Subscribed. Excellent content. Thanks

Finally someone explains this

This is fantastic! Awesome work! Thank you

Wow great explanation. Worth my subscription, and I look forward to more of your work.

Excellent animation. Very clear.

Liked and subscribed. Very clear explanation.

Thanks! Just what I wanted!

Seems that having both cabin cooler+heater on might serve task of reducing water content from the air - effectively in+built dryer so windows do not cover with frost.

Amazing vid - amazing system!

Hi bro, i'm a Chinese Tesla fan and a Chinese KZfaqr. I learned a lot from this video about Tesla heat pump! Super helpful! Can i use this as a material to introduce "How tesla heat pump works" to Chinese audience? I will give you record and tell them this research is from your channel.

Brillant!

Very nicely explained 👍keep it up .

Keep making such videos bro 🙏.. really awesome and amazing ❤️💥

Excellent video.

Amazing video!

This system is mad genious

Thank you for the excellent video. It would be a great help and I am sure a lot of work if someone would post a .pdf block diagram. Also, an explanation for the symbols and abbreviations such as PCS. Thank you and stay safe. 🚘🇺🇸

It was an outstanding explanation! I have some questions. Dose PCS in the image mean "Power Covers ion System"? And also dose "R" meaning "Reservoir" or "Receiver"?

Nice and clear explains. It’s better to start with compressor instead of chiller since that is where everything starts. Curious how valve leakage is tackled by 8 port valve. Are 15 modes really necessary? certain modes sound more likely a redundancy like waste heat recovery from battery at ambient below -10C

why do you need a condenser and evaporator in the cabin as different devices? Couldn't you use the same one having both functions depending on the temperature of the coolant?

This is awesome man, holy shit!

grt work keep it up

thanks a lot for your effort, Tesla did made sth new. I have 1 question, 6:21 what is the R stand for (Botton of the chart)?

The 2021 refresh Model 3 has this same system now too. (The Model 3 did not have this at the time this video was made.)

Great video. Really shows the genius behind the system. Those Tesla engineers are the cream-of-the-crop. There is no way old auto companies will gain enough control of their suppliers to allow this level of systems integrated thermal management. You must be vertically integrated to do something like this.

Bloody clever

Really interesting and well explained. But I'm confused why was the chiller able to remove heat from the atm air in condition 1 (atm is > -10C), but wasn't able to do the same in condition 2 (atm is still > -10C)? (EDIT: Its a typo in condition 2 page at 7:58. Should be showing < -10C).

Thank you.

How big would this have to be to heat/cool an apartment or a house?

🤯

Very Awesome. Keep it Up! Oh, and happy rocky road Day! xo

Excellent Videos! One Question: What does the "R" mean between LCC and Radiator?

Mine isn’t working brand new car... can’t cool in Las Vegas heat...

What is the difference between Model Y vs Model 3 from thermal system point of view?

Is it good to have such a mixed and unrepairable system??

what are the working fluids again?

You should have a job creating these for companies

From the Battery Day event they said they want to replace residential gas heating with batteries. I think they may make something like a combined Powerwall 3 backup house battery + HVAC + Hot Water Tank to recycle all the waste cold/hot energy and even the water condensate Elon mentioned on Twitter "Could maybe tap the condensation for water too. Seems odd that HVAC systems make pure, fresh water & just dump it on the ground."

The limit

Will the heat pump cool a bowl of hot curry ?

What did you mean by inactive LCC?

What software does you use to create such type of videos? Great video by the way Gr8 explanation

What is the 'R' and the PCS?

So what you're saying is that Tesla is more advanced than a golf cart ?

What could possible go wrong?

Hey can you put a link in your description where i can get that patent file

i am so confused now : )

Seems like their engineers did some acid and made this way more complicated then ut needed to be.

Good job. I can’t stand the word “heat pump” it’s all just the refrigeration process. A heat pump is just an AC with a 4 way valve. They called it “heat pump” because they needed to advertise the word “heat” in it.

Schade dass es das nicht auf deutsch gibt

Theoretically this looks great but what about real life efficiency. Can we have some discussion on this😊

Well explained... But they could of have made the system less complex. Electronics are not manufactured or designed very well these days with longevity in mind. There are so many ways for this system to break. I think

I thought that electric cars were supposed to be simpler than ICE cars? And this is just the thermal management system!

You're really good, this video is proovatory. But your speech is not in the level keep trying and you will be really good

Google.de

Confusing

It is Octovalve. Not Ottivalvle as you continue to repeat.

Nice try. Get a speech coach.

I laugh at these over engineered over complicated computer /tracking devices on wheels, what mechanic would work on this? you Need Airconditioning experts , high voltage AC/DC electrical engineer, An I.T. expert and god knows who else. It's a joke, a totally disposable car that will never even last long enough to ever be called a classic historic vehicle. This is because they won't be worth replacing the battery. Which you would need electrical fitters and HI voltage AC/DC engineers to do. Till charging times and battery technology changes they are not a viable option for road trips of transportation of goods.
