The AC in a prius runs directly off of the HV DC batter pack. Go find a junked prius and loot the AC if you need some DC powered cooling.
No, the Prius air conditioner compressor is AC. The Prius inverter electronics converts the HVDC to the correct AC frequency to run the motor. So you'd need both the compressor and inverter assembly, which also includes the inverters for the motor-generators that move the car. And a 200V DC power supply. And all the right computers to get the inverter assembly to do something useful.
You'd wind up with a whole bunch of a Prius just to get a silly air conditioner.
The Prius also uses an electric air-conditioning compressor motor so that cabin cooling is maintained even when running in electric mode only. A second dc/ac inverter, with circuits located on a second ICU controller circuit board ringed with TO-packaged IGBTs, is deployed to power the electric A/C compressor from the HV battery pack. The A/C inverter IGBT packages are bolted to one face of the substantial heat-sinking enclosure of the ICU.
