Yes and no. If you can design the system to work with ambient temperatures with direct cooling from, at most, dry ice through blowers, then you don't have to "waste" space on additional AC units, which is extra weight and extra cost - although AC units seem to be fine for the drivers, sitting in the pits or the paddock...
It also means it is one less thing that can fail during the race. You don't want half your pit crew disappearing, because they double up as IT support, because the AC in the data container is on the fritz and you aren't getting telemetry and can't communicate with the driver.
