Here is a RAPM that I use... the NetworkAir PA1000 Air Cooled Self Contained system (AP7003). Believe it or not, Cooling is a major sector of APC. On big systems, like Lieberts, the ACs are more than the UPSes
I bought mine to run on my generator during the Hurricane sagas we had going on a few years ago. During Wilma, this baby managed to cool my bedroom down to about 81.9 degrees at night.
So while its not going to replace your central air, it does work nicely to supplement existing AC systems. At about $300 its a good price point.
