Personal AC suit
Climate that lasts a shift.
A hooded cooling suit for personnel who work 6 to 8 hours in heat. Chilled air at the head, a closed liquid loop on the torso, and a belt pack that holds the day.

Runtime is pack watt-hours × 0.91, divided by compressor, pump, and control load. The compressor scales with the gap between ambient and comfort, then with workload, hood drag, and intensity.
The suit
Hood. Loop. Pack.
Personal AC is only useful if it lasts the shift and stays on the body. RIME splits the load: climate at the head, liquid on the torso, power on the belt.
