big time help needed!!!100voltcomp used as 115volt on 220volt :D

[quintus]

please help me out guys!!!
ok this is the ideea: i wanna use this comp http://www.xtremesystems.org/forums/showthread.php?t=164995&highlight=100v to cool another stage with a mix of r23 and r170(i realy hate oil separators:D)
so here are the foto's:

1 is the ''transformer'' i wanna use thisto power the 100vcompressor and fan on 115V what do u think?otherwise 105 is fine i guess
2 is the fan white yellow and black?:eek:
3 ...
4 is the compresor with it's blue red and grey

thank you!

Usually, I am quite good at electrics, but I am not yet sure, which cable belongs to which unit. Please post some additional photos:

1. Which cable belongs to which device.

2. Which capacitors are present and which value (µF) do they have.

You will have no problem running this compressor and fan on 220V.

Where do you come from and which voltage do you really have? 220? 230? 240?

Regards,

Philipp

hi,

first picture: as u can see i have my hand on the ''transformer'' the wires in my hand are from the compresor(blue, red and gray)

second picture is the fan in my hand and i show off the ''molex'' of the fan, colours are: yellow black and white

third picture is the electrolytic capacitor wich belongs to the compressor it is 80microF see the attached picture!

last picture is the top of the compressor u can see there the safty dingie to the right and more to the right u can see the ends of the wires in my hand: red blue and gray

thx

PS: i think i should have 220v but here is going ~ a lot, at work i have around ~190volt at home 240volt so lets say 220 ;)

[PhilippF]

Isnt there another capacitor for the fan with 8µF around somewhere?

[godmod]

For 230V operation you would at least need a capacitor that is rated for 400V.

[quintus]

hei,
maybe u dont understand but the transformer will give 115volt to the compressor and to the fan, i will not use them directly on 220volt!
the fan did not have a capacitor!:)

[godmod]

Yes would be better to do so!
I kind of said this also in response to what Phillip said, that you can run it directly on 220V. ... I don't understand this, cause according to P = U² * R the current draw would be way too high for the windings :shrug:

;) i will run it thru the transformer :D

[quintus]

@PhilippF: u are right there is 1 next to the big 80microF i didnt realize it sorry!
some1 did the testing today and something is wrong(sucking much to much energy, intensity of the light from the bulb is going downnnnnnn) so i guess this toy goes in the trash:)! maybe the transformer maybe the compressor dunno for sure if u guys wanna see the way has been wired, just to check let me know:)

thread ready to be deleted :D

thx guys

Of course you cant run a compressor rated at 100v to 220v. PhillippF was probably trying to say something else, maybe he can clarify :)


quintus, the 80uF capacitor is the starting capacitor.

From what i see in the first picture you got the yellow wire-common, red wire-start, blue wire-run. You need to verify this with an ohmmeter. Between Common and Start you should have the smallest resistance r, between Common and Run you should have a bigger resistance, between Run and Start you should have R+r added together (this way you can also check if the compressor is any god ;) if you haven't done it already).

The thing that connects yellow wire and brown wire must be a thermal protection terminal. Leave the connection like that.

Connect blueW to N, Connect brownW to L, Connect redW to capacitorPin1, Connect capacitorPin2 to relayPin1, Connect relayPin2 to N. Thats it...

Now you wonder what is that relay. That is something you need to disconnect the starting winding from the circuit. You need to get one or you cant use the compressor.

Ok, for the 220V thing:

The whole unit has to be run through the transformer. You connect Mains to 0 and to 220V on the transformer and your unit to 0 and 105V on the transformer.

I am sorry, but from the information given, I cannot tell you for sure how the rest of the wires are connected to the capacitors, fan motor and compressor.

Are you sure the 80uF capacitor is a starting cap? For a compressor of that size, 80uF is about right for a run cap. Starting caps are on the order of a few hundred uF. Also, run caps generally have metal cases while start caps generally have plastic cases.

I agree.

Im with Marru on that that 80uf cap. I think an 80uf capacitor falls in the range of starting capacitor.Most rotary compressors have run capacitors that fall within the range of 20uf to 45uf.

Star882 - The size of a compressor don't mean anything when it comes to a capacitor. Heatpumps all have run capacitors that are normally around 25uf and there compressors can be up to 5Tons (household heatpump).

[star882]

It depends on the voltage as well. At higher voltages, the needed uF value of the capacitor decreases.

If that picture of the capacitor was as it was installed, I think it connected directly as the colors of the wires attached match the colors of the wires from the compressor.

But please post pictures of all other parts so I can make sure.

ok, the unit is all trashed and the snakes(cables) are all around so i will come back tomorow with 2 pics, 1 of the way i wired the fan(yes is working,i still dunno if the cables are in the right way :D) and second the wiring of the compressor.
yes there are 2 releys but it got so so so many ''pins'' where i can insert the wires that bleah, me and electronics total noob:D

If there are relays than that capacitor may just be a start-assist capacitor thats is only engaged when the compressor starts.

[star882]

What do the relays look like? They could just be control relays.
