@KOOL2011 More precisely it A/C for the mass amounts of electronics that are on board the aircraft. Instead of using the aircrafts own power supply, they just have a portable A/C unit on a truck and the hoses attach to the ports underneath the aircraft in order for the computer equipment to remain at a low operational temperature. During flight obviously, they use the outside air temperature at high altitudes to keep the equipment cool.
