Commercial Airplanes generally use a device called a Air cycle machine for Heating and Cooling of the Airplane basically this Machine controls the temp of the airflow entering the cabin by a valve the either directing hot air through a cooling turbine or around it. The airflow to the cooling turbine comes from bleed air that is taken off the compressor of the aircrafts engines. Ventilation of the cabin is though a outflow valve that is used in the pressuriztion system of the aircraft, this is what allows you to breath at high altitude with out wearing your oxygen mask. If this system does not work right you get the rubber jungle of masks in the cabin. Also a big% of air in the cabin is recirculated.

HVAC stands for heating, ventilation, and air conditioning. That air you feel on you in airplanes is the HVAC system. Space craft have it too...
Just part of the design...

At high altitudes, the temperature can drop to below freezing. This would make for very uncomfortable airline travel so HVAC regulates the temperature/humidity to a level that is comfortable based on human needs.

Airplanes require heat, ventilation and air conditioning!

The holiday is powered via rockets, that can function without oxygen interior the vacuum of area. maximum planes are powered via jet engines, which require oxygen interior the air to function. the two use Newton's 0.33 regulation to propel their craft.
