Polarized Refrigerant oil additives

RE: thread403-93768

I note that some years ago in the thread above, that a notice of intent to use a PROA was posted by a MONO1 (user name). His reasoning for using it was sound and he was going to let us know the overall outcomes of his actions.

If MONO1 is still an active member and can let me know how he went with this matter, it would be greatly appreciated.

Thanks

Further to my previous posting, i have read a great deal about the thoughts of Refrigeration engineers about Polarized Refrigerant Oil Additives., Many thoughts have been to simply write this stuff off as "snake oil". Some of you guys have backed the science behind the theory but doubted that they would work in practise and others (not many) have supported them.
Last month i witnessed the use of 30ml of a product called Permafrost being applied to a 5 year old split system 8KW air-conditioner. The ambient outside temperature was 30 degrees celsius (yes i'm metric). We had an infra red thermal gun aimed at a set point on the vent outlet. The airconditioner had been running for 1 hour and the compressor was running. The permafrost was administered and within 5 minutes the temperature had dropped to minus 2 degrees celsius a temperature difference of 9 degrees.

It was one of the most impressive tests i have ever witnessed. Added to this was the fact that the compressor was distinctly quieter.

Can anyone tell me what possibly could cause such a dynamic change in this split system other than what PROA's are designed to do? I am cynical and skeptical in most things, but i am afraid that seeing is believing and unless someone can tell me what else could possibly have caused the change i mentioned above, then maybe the 70% of PROA skeptics might want to re-think there position.

Am i alone in this matter or are there others out there who have witnessed PROA's in action?
