PURPOSE: An air conditioning apparatus is provided to reduce noise caused by the resonance of multiple fans by operating multiple fan motors using sensor values sensed from vibration sensors. CONSTITUTION: An air conditioning apparatus comprises multiple fans(121B,122B,123B,124B), fan motors(121A,122A,123A,124A), vibration sensors(141,142,143,144), and a controller(130). The fans generate an air flow to heat-exchange air with a heat exchanger. The fan motors rotate the fans. The vibration sensors sense vibration generated when the fans are rotated. The controller controls the operation of the fan motors using the results sensed from the vibration sensors. |
