[@initialrinitialo7370]

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.

[@LMF5000]

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?

[@DortuAirCond_ACmobil]

[@Dan0rioN]

@@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

[@VanwithTim]

@@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

[@jisookim9971]

​@@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.

[@speedkar99]

[@flagmichael]

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.

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.

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.

And when it needs to cool down, does it just run the engine?

@@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.

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.

The electric scroll compressor is smaller and probably lower power than the mechanical side.

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)

[@busterscrugs]

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

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.

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.

Nice video ☺️❤️

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...

[@tommy27usa]

Why the scroll type and not screw or centrifugal? Any reason?

[@speedkar99]

Every compressor has a unique design...I have two other videos on ac compressors ..piston and variable ....it's interesting

[@tommy27usa]

@@speedkar99 all your videos are!

[@olisahopene947]

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.

[@ricolasbest6861]

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.

[@flagmichael]

Since 2004 Toyota has used only electric compressors in their hybrids, and they are sized for the job. Before that it was only mechanical.

[@sassyvisuals2432]

Is it possible to have this hybrid compressor on a normal car ?

[@justsomeone89]

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 !

[@aaronpeople101]

This is very much like an old school Vw g-lader supercharger. Very cool to see this tech still in use.

[@speedkar99]

G-lader?

[@aaronpeople101]

@@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.

[@justsomeone89]

@@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.

Besides robbing the parts-bin at a dealership.....how do you get all these used parts???

[@speedkar99]

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.

Wow... 2 modules AC compressor works mechanically or electrically. 👍🤝 keep learning..

[@speedkar99]

Yep they work in unison

Wasting Car Radiators Heat Instead of Using it for Air-conditioning Vapor cyclic refrigeration methods and systems are either 1. Vapor-compression refrigeration; 2. Vapor-absorption refrigeration (no compressor); or 3. Vapor-adsorption refrigeration (no compressor) In adsorption refrigeration, the refrigerant or adsorbate vapour molecules adsorb onto the surface of a solid instead of dissolving into a liquid. While in an absorption system, an absorber absorbs the refrigerant vapour into a liquid. Adsorption refrigeration also includes a generation process where refrigerant vapour molecules desorb from the solid. A variant of Vapor-absorption refrigeration is the Electrolux Refrigeration is also known as Domestic Eloctolux refrigeration or sometimes known as Three fluid Refrigeration as it uses three fluids for the cooling process which are ammonia, water and hydrogen. Hydrogen gas is used to increase the rate of evaporation and hence rate of cooling. No pump or compressor is used. The absorption cycle is similar to the compression cycle, except for the method of raising the pressure of the refrigerant vapor. In the absorption system, the compressor is replaced by an absorber which dissolves the refrigerant in a suitable liquid, a liquid pump which raises the pressure and a generator which, on heat addition, drives off the refrigerant vapor from the high-pressure liquid. Some work is needed by the liquid pump but, for a given quantity of refrigerant, it is much smaller than needed by the compressor in the vapor compression cycle. In an absorption refrigerator, a suitable combination of refrigerant and absorbent is used. The most common combinations are ammonia (refrigerant) with water (absorbent), and water (refrigerant) with lithium bromide (absorbent). Adsorption refrigeration was invented by Michael Faraday in 1821, even though the basis of artificial modern refrigeration dates back to 1748 with William Cullen experiments. Adsorption refrigeration technology has been extensively researched in recent 30 years because the operation of an adsorption refrigeration system is often noiseless, non-corrosive and environment friendly. In the early years of the twentieth century, the vapor absorption cycle using water-ammonia systems or LiBr-water was popular and widely used, but after the development of the vapor compression cycle it lost much of its importance because of its low coefficient of performance (about one fifth of that of the vapor compression cycle). Absorption refrigerators are a popular alternative to regular compressor refrigerators where electricity is unreliable, costly, or unavailable, where noise from the compressor is problematic, or where surplus heat is available (e.g., from turbine exhausts or industrial processes, or from solar plants), and in recreational vehicles that carry LP gas. It is also used in industrial environments where plentiful waste heat overcomes its inefficiency. So, Why we Waste Car Radiators Heat Instead of Using it for Air-conditioning? The heat energy in car radiators could eliminate the need for compressors and be used in the generator process in Vapor-absorption or Vapor-adsorption systems for car air-conditioning. It is better to utilize cars engines surplus heat using adsorption/ absorption systems low efficiency rather than waste energy into air, and using more energy to run compressors. Not only the World wastes cars’ heat but also consumes huge energy in air-conditioning and refrigeration in too many countries having high solar heat by using compression refrigeration wp.me/p1OEJz-1LZ Surely, you see my point. Do you have a reason for this waste?

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?

Can a bad motor stop the vehicle from starting?

[@catsspat]

Does Honda still do this? Seems unnecessarily complicated. Toyota's modern hybrids just have electric everything (refrigerant compressor, water pump, etc.) and don't have an accessory belt at all. It doesn't matter if the engine is running or not. A/C is always electric.

[@spikester]

The chevy volt did fully electric compressor along with electric brake accumulator & electric power steering in 2011. The only belt it has is for the ICE water pump.

[@speedkar99]

Im not sure if they still do this. But I find it inefficient, and electric everything would be the way for future cars.

[@flagmichael]

@@speedkar99 I'm not sure either, but unless Honda has changed the way their hybrids work (which should change the Integrated Motor Assist designation) I bet it is still done that way. I looked in Rockauto and the 2015 HCH (the last year it was sold in the US, at least) listing shows a compressor that looks just like yours. In 2021 they only have the Insight but no listing for a compressor. Your guess is at least as good as mine.
