In order to lower the interior temperature, air conditioners utilize chemicals that absorb the heat when they are converted from liquid to gas. By evaporating and condensing the chemicals repeatedly, A/C is able to cool the down atmosphere and make it bearable. When the thermostat detects that the interior temperature is at the ideal level base on user input, it will temporarily deactivate the A/C unit. The thermostat will immediately reactivate the air conditioner when the temperature of the vehicle interior rises above the desired level.
