I don't know where you are posting from, but I believe hvac-talk.com, and most of the people who post here are from North America, where I believe R290 (propane) is illegal to use as a refrigerant in an air conditioning system.

i know that but i'm from PETRA company in Jordan and i want to get a compressor for testing purposes
There are lots of small capacity R290/R600 compressors currently available for the residential and light commercial refrigeration market, but not much for A/C....as yet.
Here's a summary of the Chilventa trade show from October 2012, highlighting all the latest products for R290. Note the larger capacity R290 compressors from Danfoss, Bitzer, Dorin, etc.
With the tight restrictions on use of HC refrigerants here in the USA, I doubt we'll ever see much activity beyond small refrigeration applications, but the rest of the planet appears to be quite active.

Wonder when propane became "illegal to use as a refrigerant"?I have an old trade magazines that shows the first centrifugal chiller made by Carrier using propane as a refrigerant.
Propane is still in use in the USA as a refrigerant mostly in the low temp market.
That's interesting. Are you sure it wasn't an absorber, using the propane as fuel to heat it?
Reading old trade magazines made me realize that we have not invented a thing in a very long time, its the other way around, we have lost great inventions, mostly because lawyers and the greed of the big corporations.
