PURPOSE:To provide an air current velocity adjusting device of a condenser fan capable of effectually preventing sleeping from being arrested owing to noise from the condenser fan at night in summer. CONSTITUTION:There are provided a condenser temperature sensor 14 for detecting the temperature of a condenser 3, a controller 16 for adjusting the number of revolutions of a condenser fan 11 with predetermined standard characteristics based upon an output of the condenser temperature sensor 14, and an outside air temperature sensor 14 for detecting the outside air temperature. The controller 16 controls the number of revolutions of the condenser fan 11 based upon an output of the outside air temperature sensor 17 with characteristics which ensures low noise compared with standard characteristics, in the case of the outside air temperature corresponding to the one at night in summer.
