Not like oil and oxygen, but not a recomended fluid for refrigeration systems.
If this is a special condenser that you don't want to replace, then there are specific flushing fluids for this type of job, but you will need to ensure they are fully removed once flushed.
See ebay, amazon and google for products local to you.
If it were me, I would consider blowing through with dry nitrogen and replace the filter-drier a couple of times once the systems has been returned to service.
Why do you think it needs flushed? What do you think is contaminating it?

I flushed mine with brake-kleen...
When I did my Nissan pickup, and my old Bronco. I also cleaned as many other components as I could. I followed the guidance per some aircon website that I used to go to a lot. (forget the name?)
I then blew it everything I could out with compressed air. Make sure you blow it out well and give it a good evacuation to ensure the moisture and non-condensible gasses are well evacuated.
Replace the dryer and install new o-rings/seals/gaskets.

There was a broke line near compressor when I got the car and after replacing it, compressor and orfice tube I could never get the pressure down on the low side, so I have take it completely apart, flushing both the evap and cond along with the lines. Ordering a new pressure switch/them control this week. I flushed both the evapator and cond with mineral spirits and then connected a water hose and flushed with it and blew it out with compressed air, let it dry in sun for the afternoon.

Just looked and specific flushing aerosol stuff is available now. Google "AC Flush Aerosol" and you can find it at walmart (17-20 bucks).
Personally I would just get some generic aerosol brake cleaner for a couple of bucks if I was doing it nowadays, and blow the whole thing out with compressed air.....let it dry well and whatnot.

Never use mineral spirits to flush AC components or compressed air.
Consider a larger condenser if you are switching to r134. New filter dryer and a different orifice tube or expansion valve for 134 conversion.
