bro you have no idea how long ive been looking for a channel where someone actually takes apart an actual auto part and explains in detail how it works
3:27 The little curved piece is the discharge valve retainer. It prevents the discharge valve from being bent in a way that might cause permanent damage. 4:54 A scroll compressor has a fixed scroll and an orbiting scroll. The orbiting scroll is driven by an eccentric with an offset center that is almost exactly offset by half of the root of the involute spiral. Check out 'scroll compressor' on wikipedia, there should be an animation showing orbiting operation. 5:10 The orbiting scroll should NOT rotate like that. Because the scroll was allowed to loosen away from the front casting, the steel balls, which act as a thrust bearing, came loose from the races and their anti-rotation feature was compromised. 5:17 The offset eccentric is actually driven slightly off its center. This forms a compliance mechanism in the event of debris between the scroll walls and also allows the orbiting scroll to press harder against the fixed scroll as rpm is increased. 6:16 Each scroll is given a teflon like tip seal that acts as a sliding seal. The orbiting scroll is anodized so that its surface finish is different from the fixed scroll. This prevents galling due to pure stiction which would be a problem if the two surfaces could co-mingle at a near atomic level. 6:21 Those are not CNC marks. They are wear marks from the wall of the opposing scroll. That worn surface for both scrolls is a stamped steel insert to prevent the wear from tearing up the aluminum. 6:45 The motor is a brushless DC. An inverter creates the phase signals necessary to drive the permanent magnets in the rotor at the correct speed and direction.
Awesome comment! Thanks for adding all that info. For the part you mentioned at 5:17, where is the compliance built in? Looks like a needle roller bearing on the back of the scroll, so I'm guessing the compliance is on the eccentric shaft? How does it work exactly?
Thank you for your videos. I followed right along, the video was paced just right, not to fast, not to complex, not to simple. Amazing what a person can by watching watching youtube. Maybe you aren't there yet, but a simple work bench made from bed rails or whatever and some 2x8s will help save your knees and back when you are my age.
Always remember when you're recharging the AC on a hybrid vehicle use strictly refrigerant only do not have the mix with oil kind. These compressors take a special oil that is made for hybrid compressors. I work on hybrids for many years
@@davidescobedo1317 Some use R1234, others use R134. Look under the hood for the system specs. It should list refrigerant, oil type and weight, and capacity of both.
@@viperstrike3827 if you're talking to me I just picked up and learned it on my own. A lot of youtubing and a lot of Google searches and I just figured it out on my own. I own a small car lot and I sell a lot of hybrids
@@speedkar99 Why doesn't it remain fully electric driven off the battery charged by alternator?? How familiar arebyiu with such things?? I have a project I'd like some words of wisdom on
@@Dan0rioN If the engine is running it would be more efficient to be driven off of the belt system. The compressor has very little efficiency loss between the crankshaft pulley and the AC compressor. To be driven electrically, you start adding in more conversion losses. The engine driven electric "motor generator" (MG) isn't 100% efficient so the conversion of mechanical energy to electrical creates wasted heat energy. Basically, any time you want to convert energy from one form to another you will want to do it in the most direct way possible. Every time you convert energy (electrical, mechanical, fluid, etc.) you will generate heat and lose efficiency. I'm no engineer though! Cheers! -Tim
@@Dan0rioNIt is more efficient if the engine is running because it is directly mechanical driven and if take energy from electrical system while it's running then it take power from alternator instead.
Another interesting vid, it's my first time seeing a scroll compressor like that. From a safety perspective, it may have been good to stress the importance of discharging capacitors before you opened the a/c control module. 600v would be quite the shock.
My first time seeing the scroll like that as well. It was quite a learning experience. And good call on the capacitor....this module sat for a long time so I felt it was safe to touch
4:55 This is a scroll pump. The same principle is used in the vacuum industry to make cheap dry vacuum. It was also used in the late 70ies for the VW Polo G40 or VW Golf G60 that had supercharged engines.
Thanks for the informative and entertaining video I like that you pack in so much into short videos as my attention span is not so great and you keep my attention start to finish... I don’t know if you have done a video on this but maybe a suggestion if you haven’t done a video related to all the fancy pollution gear not so much the newest stuff as you don’t want to be tearing apart new cars but I’m sure there have likely been some weird setups in the recent past. The other thought is maybe turbo or super charged engines once again if not already covered. Thanks for the great vids keep up the good work

@@speedkar99 Fact. 2005 Civic Hybrid (with similar IMA) would disable engine shut-off at stopped with A/C on (unless Eco mode button was on, then engine would cut out and only A/C fan would run. No dual mode compressor to my knowledge).

Hey , i haven't seen a best version than this to explain a hybrid compressor. Awesome. Can you please do some tear down video explanation of Tesla Heat pump
Awesome work! Missed the other compressor video so I am happy to see this. Given the complexity, this feels like a ~700 (RockAuto)/$1500 (stealership) part.
I think either an all electric or all mechanical would be cheaper. Hopefully newer hybrids use all electric. Reduce some complexity. Thanks for sharing! Didn't know they made a scroll type compressor in automotive. More efficient.
Scroll compressors have been in use for a long time for residential and commercial air conditioning. Their technology has even expanded so that they can be used in low temp refrigeration as well.
Oh my. Not only will this compressor be much more expensive, the repair techs will need to be trained in high voltage hybrid automotive repair. What an interesting design.
The significance of HV in hybrids is greatly exaggerated. In the Prius, for example, about the only way you can contact dangerous voltages is to remove the inverter output cover and turn the system on. I rebuilt a Prius battery (19 years old) last month and did it all bare-handed. I wanted to get a feel for how much of the battery voltage I could contact from the fingers of one hand to the fingers of the other without it actually hurting but there was only one step where that was possible and I completed it (removing the bus bars) before I remembered it. Two years ago I retired from the communications/IT field service department of a large electric utility. Working in substations I occasionally made contact with 135V DC from the substation battery in the control house. It made me flinch, but it didn't actually hurt. I made contact with the 54V DC from our communications batteries many dozens of times and rarely noticed unless one contact point was the thin skin underside of my arms - then it was like a pinch. My big DC contact was in a tube type radio in 1967. I made excellent contact hand to hand with 300V plate supply - it felt like I was hit in the back of the head with a 2X4. If it had been 240VAC I would not be here to tell you about it.
I have a 2014 Civic Hybrid whose biggest issue is that if the climate system determines that the A/C clutch needs to be used, it keeps cycling even during heavy accelerations, where it is very noticeable. The system would be much more efficient if the electric A/C was used at that time. Is it possible to reprogram the ECU or HVAC unit for that? (i.e. if the system determines the mechanical A/C is required, but I am accelerating heavily, mechanical A/C is temporarily shut off and the electric A/C takes over until I reach my cruising speed)
My 2002 Prius doesn't have hybrid AC. It just has a thermally-insulated evaporator core that can blow cold air for several minutes when the engine is off.
@@speedkar99 Yes. Runs the engine for about a minute, and then shuts off for another five. With the fan on low, it will even glide in EV mode for a few minutes.
The engine runs continuously if the AC is set to MAX. Needless to say, that plays Hob with the fuel economy. They went to electric compressors from 2004 on. We lived in Flagstaff when we bought our first 2002, but my wife always used MAX when she went to Phoenix to visit family. Later we got a 2010 and it was _much_ better!
On an 03 civic hybrid the compressor went out.. and I just found out my condenser is trash needs to be replaced.. now I'm going to bypass the compressor for now, and route the belt to just the CS, water pump and tensioner. I ordered the condenser and compressor and when they both come in I'll change them out. Question: can I replace the condenser and compressor until I get to a garage and have them evap and recharge the new parts then route the serpentine belt to OEM settings??
Good video Does the electric air-conditioning pump need to be installed horizontal or can you mount it vertical I'm asking due to it having lubrication oil
I had just replaced the compressor on a 2014 civic hybrid, and the A/C still does not work.. I have filled the system with the correct spec of refrigerant, and inspected fuses that may be related to the system.. Not sure where to go from here, may be i’m missing a certain fuse, or relay that the old compressor may have caused to become faulty… any idea what to check?
Thanks. I had heard that hybrids use an electric compressor, but didn't know the details. I didn't know some also have a belt drive. Perhaps some are electric only, which allows them to be mounted anywhere. I wonder why they use a scroll rather than swashplate w/ pistons as in common Sanden & Denso compressors. It does make it smaller and I've heard scrolls are more efficient. Perhaps also less likely to stall the motor when pressure builds up. I heard these compressors are very expensive to replace.
Where is the clutch magnet coil and how is it activated? The two compressor outputs must have some kind of one way or non return valve inside. Great teardown vid btw. Thanks..
Dear Speedkar99, I can't find another way to reach you other than the comments area. I need your help, I'm trying to hook up a camera on the passenger side mirror that turns on only when I push the signal lever up (i.e. activate the right turn signal) but I need to get a constant current that keeps the camera on while the signal is flashing. Any idea how to do it?
Depending on what car it is and the way it is wired, a relay? If it is a CAN Network design give up. From the switch to the indicator will be a wire going to a relay, you could use this to energise a relay, which could be the power for your camera....why you need a camera though? Seems a lot of effort.
@@philpersonal4656 I upgraded my 2007 Sienna LE sound system. Now I have a back up camera, I have an extra Video input that I can use for an extra camera. I can hook it up right now but it's going to be on all time. I just want it to turn on only when needed. I don't want to use a switch, because my hand will be busy with a click on the head unit to switch the display to video input.
@@landshass2849 seems like it could get complicated. Would the head unit auto select the camera channel when camera came on? Otherwise you'd have to change input on radio manually each time camera came on. A relay would be best device for switching on a camera from indicator stalk. Sounds like you need to go to an audio-visual specialist. Also, most people like a reverse camera, why you want it on indication?
You'd need a relay that's wired to the turn signal circuit, but one that stays on for the time in between flashes (something with a capacitor or microcontroller?) Maybe there's a logic gate that can help. Otherwise you can try tapping into the circuit from the turn signal stock side to fire up that relay and power the camera so you don't have to deal with the flashes

Sir, recently, I don't hear fuel pump priming sound when key at ON or engine running in my i20 petrol about 10 days ago. The same happens when fuel level is full or halfway full. However, there's no any problems while driving any car, no pulling power issues, etc. All perfect. Earlier I used to hear fuel pump priming at key on. But this prime sound is not hear recently. Is this normal? Is the fuel prime should always ON or only sometimes when keys at ON? Please kindly help on this.
The electric scroll compressor is smaller and probably lower power than the mechanical side. The separate output ports are necessary probably to prevent backflow in the non active scroll when only one is active - probably has solenoid activated valves on the other mating piece to those output ports.
Interesting vid. Mayb U can answer a question for me. Hi compressor in my 2010 Camry hybrid is making a terrible noise. I told the missus not to use the aircon till I got it looked at. Anyway she continue to use it for next month. Now it won't turn on should I replace it with a second hand compressor or does it just need gassing and maybe oil. Cheers.
thanks you , very informative video, now I know how the compressor works. Just curious how long can the electric run the car aircon if left stationary without starting the car.
It is not 3 phase, it Is an inverter compressor. It is working on frequency. The winding connection similar to 3 phase Ac, but this compressor receives DC voltage as a pulses. I know the new inverter compressors are confusing many people. They use an inverter compressor so will not draw high amps when start to save some of battery energy. If you look to the inverter board, typically you will find 6 Igbts or they could be impeded in one IC and it cooled by heatsink.
I've never seen a compressor like this before. Then again, I've never seen the guts of car compressors. Very impressive and clever. Reminds me of the Wankel engine on steroids!
Great. Can you do Toyota hybrids ac compressor please, it’s only electric and works with 220v , very interesting what’s inside! Thanks in advance. You are great 👍
Very interesting. I would also like to see a Tesla heat pump teardown. Let's say there was a damage to the rotor/stator/scroll wheels, would it be possible to change out those parts? Like CNC-mill a replacement part?
So the output from the electric one is not as cool as the one on mechanical one? Since the electric one is smaller? What about those on Toyota/Lexus hybrids? Thanks.
I watched all the accord transmission vids then thought I should switch the gear position sensor first. The spiderwebs let me know the shaft was not turning so I found the broken shift cable assembly. It ran for 5 minutes fine then rougher and worse till I couldn't get up on ramps. Now the dlc sayes no connection and I lost spark. The plugs are soaked in gas. Please help.
Are you sure that is permanent magnet motor and not a 3 phase AC synchronous motor? That looks more like a squirrel cage rotor, than one with permanent magnets embedded in it. That big capacitor would be the phase shifter. I would love to see the schematic for the boards. It looks like a quality build.
I don't know about the Honda motors, but Toyota uses permanent magnet rotors with 3 phase field windings in the hybrid transaxle. I would expect to see the same technology in the compressor, particularly since the compressor speed could be precisely controlled that way.
Interesting. I was asking myself how does this system work on hybrid vehicles. On Tesla the A/C compressor works completely electrical and are now used as heat pump to give heat in cold countries, by reversing the condenser and evaporator cycles!
Heat instead of head, I presume. A priest, a minister, and a rabbit walk into a bar. The bartender asks the rabbit, "What'll you have?" The rabbit replies, "I don't know. I wouldn't even be here if not for autocorrect."
Minus the heat pump feature, electric car compressors are similar to those used in 2nd gen Prius on up, Ford Hybrids after 2012, and most other modern Hybrids. Most modern Hybrids have a compressor that is powered by electricity only, capable of increasing or decreasing cooling capacity depending on the need.
Stopped wathching ave channel when he mentioned mud huts. Speedkar99 dont know your name but i love your channel, you are excellent at explaining technical stuff, thumbs up for all the effort you put in for every episode.
@@speedkar99 yes volkswagen used the same type of compressor as a supercharger for a number of models in the late 80's and early 90's The Polo(2 and 2F) G40, Golf (2) G60 and Corrado G60 Mainly in Europe. Those superchargers are very delicate and that is the main reason this tech is not used any more. They were not that reliable and very expensive to make and repair. So it is odd but interesting that the same tech is used once again years later for an air con compressor. The name G-lader is because of the shape of the scroll wheel which looks like a G. Lader means charger.
The inside of an aircon or refrigeration system has to be almost clinically clean for it to function correctly. The oil doesn't get contaminated by combustion by-products like in an engine.
@@speedkar99 many Honda equipped with L15 engines, notoriously Honda Freed. The AC compressor jammed and instantaneously break the compressor drive shaft (drive pulley still turning but does not turn the AC compressor internal). I don't know if this model is available in Canada.
hi, where in canada? are you for hire? we're purchasing a van rv conversion, considering mini-split, vs adding electric compressor to run the trucks AC to cool the cab...
As cool as hybrids are, I'm glad I don't have one. That's a lot of extra complication in the A/C system that could go wrong, between that control module, the electric motor, and the compressor itself burning out. Probably a lot more expensive than a conventional compressor to replace. Something that has always been simple is now excessively complicated lol
No it's 3 phase AC...see the end of the video where I took apart the driver that converts DC to the 3 wire AC... There's also 9 coils in there 3 for each phase
Kinda 2 mechines of different type that work alternately need their on auxilaries and utilities for the same job, redundancy. End up more expensive to own a car, which defeat the purpose of hybridizing. 😄
@@aspecreviews It truly is. The first gen had trouble with MG2 burning out because they ran the system on 273V. In 2004 the inverter included a voltage doubler that cut the current in half (and the heat by 3/4). Since then they may well be the most reliable car transmission made. (I have done enough clutches and cursed at enough second gear synchros to toss manuals out of the running. The last one I did had only lasted a year before the new pilot bearing seized. GRRR!)

The engine runs continuously if the AC is set to MAX. Needless to say, that plays Hob with the fuel economy. They went to electric compressors from 2004 on. We lived in Flagstaff when we bought our first 2002, but my wife always used MAX when she went to Phoenix to visit family. Later we got a 2010 and it was _much_ better!
@@flagmichael Had to go in for an emissions test once and MAX AC was the only way to keep the engine running.
On an 03 civic hybrid the compressor went out.. and I just found out my condenser is trash needs to be replaced.. now I'm going to bypass the compressor for now, and route the belt to just the CS, water pump and tensioner. I ordered the condenser and compressor and when they both come in I'll change them out. Question: can I replace the condenser and compressor until I get to a garage and have them evap and recharge the new parts then route the serpentine belt to OEM settings??
Compressor has a lot of balls.
Haha
Good video
Does the electric air-conditioning pump need to be installed horizontal or can you mount it vertical
I'm asking due to it having lubrication oil
Yes it can be mounted how it is in the car. What are you trying to make?
Great work
Thanks
I had just replaced the compressor on a 2014 civic hybrid, and the A/C still does not work.. I have filled the system with the correct spec of refrigerant, and inspected fuses that may be related to the system.. Not sure where to go from here, may be i’m missing a certain fuse, or relay that the old compressor may have caused to become faulty… any idea what to check?
Extremely enlightening
Thank you
Glad you appreciate my work
Thanks. I had heard that hybrids use an electric compressor, but didn't know the details. I didn't know some also have a belt drive. Perhaps some are electric only, which allows them to be mounted anywhere. I wonder why they use a scroll rather than swashplate w/ pistons as in common Sanden & Denso compressors. It does make it smaller and I've heard scrolls are more efficient. Perhaps also less likely to stall the motor when pressure builds up. I heard these compressors are very expensive to replace.
Where is the clutch magnet coil and how is it activated? The two compressor outputs must have some kind of one way or non return valve inside. Great teardown vid btw. Thanks..
Dear Speedkar99, I can't find another way to reach you other than the comments area. I need your help, I'm trying to hook up a camera on the passenger side mirror that turns on only when I push the signal lever up (i.e. activate the right turn signal) but I need to get a constant current that keeps the camera on while the signal is flashing. Any idea how to do it?
Depending on what car it is and the way it is wired, a relay? If it is a CAN Network design give up. From the switch to the indicator will be a wire going to a relay, you could use this to energise a relay, which could be the power for your camera....why you need a camera though? Seems a lot of effort.
@@philpersonal4656 I upgraded my 2007 Sienna LE sound system. Now I have a back up camera, I have an extra Video input that I can use for an extra camera. I can hook it up right now but it's going to be on all time. I just want it to turn on only when needed. I don't want to use a switch, because my hand will be busy with a click on the head unit to switch the display to video input.
@@landshass2849 seems like it could get complicated. Would the head unit auto select the camera channel when camera came on? Otherwise you'd have to change input on radio manually each time camera came on. A relay would be best device for switching on a camera from indicator stalk. Sounds like you need to go to an audio-visual specialist. Also, most people like a reverse camera, why you want it on indication?
You'd need a relay that's wired to the turn signal circuit, but one that stays on for the time in between flashes (something with a capacitor or microcontroller?) Maybe there's a logic gate that can help.
Otherwise you can try tapping into the circuit from the turn signal stock side to fire up that relay and power the camera so you don't have to deal with the flashes
@@speedkar99 thanks, I appreciate the reply. I'll update you with the results.
So could you power your truck cabin AC through the factory vents with a 240v AC power source?
Say Bro, I love the toothbrush pointers!!!
Please keep up the good work, and explanation!!!
And I got old pants, from my brother, if you ever need any rags!!!
Sure send the rags over lol haha
@@speedkar99 Sounds like your very good missus has put a stop to you using her wardrobe after using her favourite nightshirt! She's a saint, lucky you're not sleeping on the couch at best or in your cardboard studio at worst. Best wishes from UK, stay safe
Very good description.
Sir, recently, I don't hear fuel pump priming sound when key at ON or engine running in my i20 petrol about 10 days ago. The same happens when fuel level is full or halfway full. However, there's no any problems while driving any car, no pulling power issues, etc. All perfect.
Earlier I used to hear fuel pump priming at key on. But this prime sound is not hear recently. Is this normal? Is the fuel prime should always ON or only sometimes when keys at ON? Please kindly help on this.
The electric scroll compressor is smaller and probably lower power than the mechanical side. The separate output ports are necessary probably to prevent backflow in the non active scroll when only one is active - probably has solenoid activated valves on the other mating piece to those output ports.
That long thin U-bent shape piece I took off the ports I bet was the valve to prevent back flow
Interesting vid. Mayb U can answer a question for me. Hi compressor in my 2010 Camry hybrid is making a terrible noise. I told the missus not to use the aircon till I got it looked at. Anyway she continue to use it for next month. Now it won't turn on should I replace it with a second hand compressor or does it just need gassing and maybe oil. Cheers.
Now I understand, this seems totally feasible to upgrade mod the older Civic hybrids. In Florida that would be huge especially for me!
thanks you , very informative video, now I know how the compressor works. Just curious how long can the electric run the car aircon if left stationary without starting the car.
thanks how fast does it spin?
Are there already fully electric ac motor on internal combustion cars.
Id think by now most compressors would be fully electric.
5:00 Your A/C compressor is basically a rotary engine.
Not quite
No. Your home fridge compressor is basically a piston engine though.
Hey my man, do you have another video about a power steering pump replacement on a Lexus es330 or camry?
Not quite, i filmed one last year but the video kinda messed up, lost some content and never posted it lol
@@speedkar99 oh man, I need your skills homie! Lol. I can do it, but man the clearance is awful ha, I know you have the finesse with these.
It is not 3 phase, it Is an inverter compressor. It is working on frequency. The winding connection similar to 3 phase Ac, but this compressor receives DC voltage as a pulses. I know the new inverter compressors are confusing many people. They use an inverter compressor so will not draw high amps when start to save some of battery energy. If you look to the inverter board, typically you will find 6 Igbts or they could be impeded in one IC and it cooled by heatsink.
my AC runs and cools for a few minutes and stops but the compressor keeps spinning, what can be responsible for this.
thanks for ur response.
I've never seen a compressor like this before. Then again, I've never seen the guts of car compressors.
Very impressive and clever. Reminds me of the Wankel engine on steroids!
Thanks, and yep it was my first time seeing inside the compressor as well
Great. Can you do Toyota hybrids ac compressor please, it’s only electric and works with 220v , very interesting what’s inside! Thanks in advance. You are great 👍
Sure, send one over !
Why the scroll type and not screw or centrifugal? Any reason?
Every compressor has a unique design...I have two other videos on ac compressors ..piston and variable ....it's interesting
@@speedkar99 all your videos are!
now whose sleeping shirt it is again please?? 🤣🤣🤣 awesome video btw
Very interesting. I would also like to see a Tesla heat pump teardown. Let's say there was a damage to the rotor/stator/scroll wheels, would it be possible to change out those parts? Like CNC-mill a replacement part?
So the output from the electric one is not as cool as the one on mechanical one? Since the electric one is smaller? What about those on Toyota/Lexus hybrids? Thanks.
Since 2004 Toyota has used only electric compressors in their hybrids, and they are sized for the job. Before that it was only mechanical.
I watched all the accord transmission vids then thought I should switch the gear position sensor first. The spiderwebs let me know the shaft was not turning so I found the broken shift cable assembly. It ran for 5 minutes fine then rougher and worse till I couldn't get up on ramps. Now the dlc sayes no connection and I lost spark. The plugs are soaked in gas. Please help.
2nd o2 sensor was the only code. I pulled the fuses checking them (ok) so no codes to get
If im not mistaken that same design is used on the g60 engines supercharger
Good to know
Are you sure that is permanent magnet motor and not a 3 phase AC synchronous motor?
That looks more like a squirrel cage rotor, than one with permanent magnets embedded in it.
That big capacitor would be the phase shifter. I would love to see the schematic for the boards. It looks like a quality build.
Correct...
I'd be interested in knowing too, the 3 phase wire may have thrown me off
I don't know about the Honda motors, but Toyota uses permanent magnet rotors with 3 phase field windings in the hybrid transaxle. I would expect to see the same technology in the compressor, particularly since the compressor speed could be precisely controlled that way.
Interesting. I was asking myself how does this system work on hybrid vehicles. On Tesla the A/C compressor works completely electrical and are now used as heat pump to give heat in cold countries, by reversing the condenser and evaporator cycles!
Heat instead of head, I presume.
A priest, a minister, and a rabbit walk into a bar. The bartender asks the rabbit, "What'll you have?" The rabbit replies, "I don't know. I wouldn't even be here if not for autocorrect."
Minus the heat pump feature, electric car compressors are similar to those used in 2nd gen Prius on up, Ford Hybrids after 2012, and most other modern Hybrids. Most modern Hybrids have a compressor that is powered by electricity only, capable of increasing or decreasing cooling capacity depending on the need.
You are master tecnician bro
Stopped wathching ave channel when he mentioned mud huts. Speedkar99 dont know your name but i love your channel, you are excellent at explaining technical stuff, thumbs up for all the effort you put in for every episode.
Wait a VW G-Lader as a ac compressor? What's that called? G35 R134a ?
Funny that they are re-using that old tech for this purpose !
This is very much like an old school Vw g-lader supercharger. Very cool to see this tech still in use.
G-lader?
@@speedkar99 look into it. Vw used this technology in a supercharger in some of their cars back in the day. Namely in the Corrado G60.
@@speedkar99 yes volkswagen used the same type of compressor as a supercharger for a number of models in the late 80's and early 90's
The Polo(2 and 2F) G40, Golf (2) G60 and Corrado G60
Mainly in Europe.
Those superchargers are very delicate and that is the main reason this tech is not used any more. They were not that reliable and very expensive to make and repair.
So it is odd but interesting that the same tech is used once again years later for an air con compressor.
The name G-lader is because of the shape of the scroll wheel which looks like a G. Lader means charger.
Crazy a/c compressor 🔰✊🏼🆗
Sure is interesting!
amazing content
I'm surprised at how clean it looks on the inside.
It has to be, if there are any contaminants then it's not good for the AC components
The inside of an aircon or refrigeration system has to be almost clinically clean for it to function correctly. The oil doesn't get contaminated by combustion by-products like in an engine.
Many Honda over here equipped with scroll type AC compressor tends to be unreliable compared to traditional piston style AC compressor.
Which cars?
@@speedkar99 many Honda equipped with L15 engines, notoriously Honda Freed. The AC compressor jammed and instantaneously break the compressor drive shaft (drive pulley still turning but does not turn the AC compressor internal).
I don't know if this model is available in Canada.
hi, where in canada? are you for hire? we're purchasing a van rv conversion, considering mini-split, vs adding electric compressor to run the trucks AC to cool the cab...
What is the difference between this air conditioning compressor vs the one Toyota uses in its latest hybrids ?
Nice video ☺️❤️
So now I'm confused I just found a channel says speedkar 100, what's up with that?
That's my second channel with other random videos, and some behind the scenes stuff, check it out.
Is the mechanical side controlled by the driver too?
As cool as hybrids are, I'm glad I don't have one. That's a lot of extra complication in the A/C system that could go wrong, between that control module, the electric motor, and the compressor itself burning out. Probably a lot more expensive than a conventional compressor to replace. Something that has always been simple is now excessively complicated lol
@ 6:46
This is Not 3 phase electric Motor.
This is BLDC Motor..
Yep, 3 phase motors don't have permanent magnets like a BLDC.
No it's 3 phase AC...see the end of the video where I took apart the driver that converts DC to the 3 wire AC...
There's also 9 coils in there 3 for each phase
So it looks like it would still work?
Except after when you use that butch snap-ring remover!
Wow... 2 modules AC compressor works mechanically or electrically. 👍🤝 keep learning..
Yep they work in unison
Is it possible to have this hybrid compressor on a normal car ?
Besides robbing the parts-bin at a dealership.....how do you get all these used parts???
I buy an old car and part it out. Sell the parts I don't need and keep the interesting parts for videos like this.
Can I still drive my hybrid car I have an Acura ilx hybrid but the ac compressor is bad can I still drive until I can buy a new one?
Interesting video! Keep up!!
...My wife's old sleeping shirt 🤣 ...
...Special snapping removal tool 😂 ...
Thanks!
Gotta use what tools are by my hand
Fantastic !
Feel like im watching a cat burglar explain how to crack a safe in great detail.. gloves & all 🤓👍🏽new sub
Man, that's a lot of parts, just for one component.
Hybrids overcomplicate things
Kinda 2 mechines of different type that work alternately need their on auxilaries and utilities for the same job, redundancy. End up more expensive to own a car, which defeat the purpose of hybridizing. 😄
regular hybrids are simpler cuz the transmission's just a planetary gearset and two motors
@@speedkar99 My Prius eCVT is just a planetary gearset and two electric motors. Basically indestructible.
@@aspecreviews It truly is. The first gen had trouble with MG2 burning out because they ran the system on 273V. In 2004 the inverter included a voltage doubler that cut the current in half (and the heat by 3/4). Since then they may well be the most reliable car transmission made. (I have done enough clutches and cursed at enough second gear synchros to toss manuals out of the running. The last one I did had only lasted a year before the new pilot bearing seized. GRRR!)
