Why Does the Space Station Need an Air Conditioner

In space, heating and cooling occur only by way of radiation � objects are warmed by solar rays warm and cool off by emitting infrared energy.

Without thermal controls, the Space Stations Sun-facing side would heat to 250 degrees F (121 C), while thermometers on the dark side would plunge to minus 250 degrees F (-157 C).
