PROBLEM TO BE SOLVED: To automatically correct setting of rotational frequency tables even when a person involved in installation work wrongly selects the rotational frequency table during installation of a duct type air conditioner, and operate a motor at a rotational frequency corresponding to air conditioning load such as the piping state of a duct.SOLUTION: This control device for a fluid delivery device includes: a power element controlling energizing of the motor; a temperature detection means for detecting the temperature of the power element; an air quantity instruction means for instructing air quantity of a centrifugal air blower; a first storage part 711 storing the plurality of rotational frequency tables corresponding to the air conditioning load; a normal operation rotational frequency table storage part 714 for storing the rotational frequency table selected beforehand from the first storage part 711 to control the motor. Based on the temperature of the power element, it is determined whether the rotational frequency table stored in the normal operation rotational frequency table storage part 714 is suitable for the air conditioning load, and when the rotational frequency table is not suitable, the rotational frequency table is changed to another rotational frequency table. |
