Altronics have a kit for a 3 phase converter, you would still need to get 240v to it, your efficiency would be pretty poor. When my alternator died I measured the current draw from the battery with the aircon fans running, 27 amps, we drove 200km home in 40C without aircon. With the full 70 amps & 12 volts minus 1/3 for fans, if you had 80% efficiency in your inverter & converter you would be down to around 400w available at the compressor at full alternator load. That wont cool much, and you would have to turn everything else electrical off. Or you could run a cooling suit and a thermo electric fridge.
