any specs pls!!! comes from an old 110volt unit(got an 220 to 110 for it, i live in europe) air con ''Beaver'' :D got also some specs on the split unit in japaneze or some asian laguage, u know those tatoose on the back of chicks that she saids means love but it truly mean .ss l.ck.r or c..ck s.ck.r :D
will need help with the wirring too, will be back with the pics
thx

What is the model # of the unit this compressor came from? I searched a little bit and it sucks because when you search mitsubishi 99% of what you get are something to do with cars. (go figure...)

Hand us the japanese language part. Some of us might be able to decipher... (not me probably, I can read some very basic ones).

Is this particularly old? Because I cannot find it on the Mitsu.. Electric site.
Edit: Duh, it must be... its R22

Well I tried, but I could not find anything.

It looks like the Displacement of the compressor is 13cc. R22 @ that displacement cant be bad?

I'm not so sure that is displacement.
19k btu is ~35ccm.
it's kinda tricky to calculate that on rotarys.

here u go guys, thx for your time. i plan an cascade and i was thinking to use this comp(damn money:shrug:)

35ccm u say? somebody can confirm this pls!!!???
or is it (cry) only 13cc
thx

Rotarys typically don't have big displacement for amount of work it can perform. 13cc would be right considering all other values are in metric.
Considering amperage usage for 100v (not 115v we use typically in US), and displacement value, it seems to be 1/2 hp rotary compressor. (oh probably with EER of something like 6-7.... it is that old after all)

damn! i find it a bit on the small side, so i got to use an nl11f(with r23) damn!
thank you guys!

I found this:
RM5510G ÓÕÌÐ. 8.330BTU R22 220V ROTARY
So, this seems to be the 220V version (without the "JVE" at the end of the model number).
Edit: 8330BTU would be approximately 13ccm.

thx guys 1 more thing before i post pics with the wirring:
because i'm kind of confuse with the power termal and electrical, can i use say an sc21 danfoss with r23 cooled by this compresor or he is not strong enought? then i go for nl11 is that ok? im ~~~~~~ ccm~~~ btu ~~~dizy
what do u mean by:
(oh probably with EER of something like 6-7.... it is that old after all)

Power terminals are all same... don't you have starting device with the compressor? As for strong enough or not, it all depends on where you want condensing temperature to be at. Since the compressor rating probably is for A/C most likely, under lower temperature you most likely are trying to use it for you will have to reduce power capacity of the compressor. On the other hand I believe SC21 is low/med temp refrigeration compressor which probably has a lot more capacity than this one does for given temp (or pressure ratio, etc).
My first guess is, this might not be bad combination but you will have to set evaporating temp of first stage to be able to handle 2nd stage dump of heat as well as correct condensing temp and volume for 2nd stage. It's up to anyone's guess right now :)
Maybe looking at my mini cascade thread might give you some idea as r-116 and r-23 are similar in many perspective (one is lower pressure tad heavier while the other is higher pressure and tad lighter).
As for EER, it is energy efficiency rating. Just something of power consumpotion vs output at rated evap/condensing temp.
