Abstract

PURPOSE: To improve comfortableness and reliability of the air conditioner, by connecting a sensor for detecting the temperature in the room and a sensor for detecting the temperature of air diffused into the room to a control unit, and controlling the revolutional speed of a motor in a stepless manner in each of the speed ranges of the motor.
CONSTITUTION: The sensor 8 for detecting the temperature of air in the room and the sensor 9 for detecting the temperature of air diffused into the room are connected to a control unit 10. Speed ranges for a motor 2 coupled to a fan are determined from the mode of operation and the temperatures detected by the above two sensors 8, 9, so as to control the revolutional speed of motor 2 in a stepless manner in each of the speed ranges of motor 2. With such an arrangement, it is enabled to prevent blowing of cool wind at the time of starting heating operation and during defrosting operation and to change the revolutional speed of fan 2 smoothly during its operation. Thus, operation of the air conditioner can be made more comfortable and reliable.
