Abstract
PURPOSE: To properly maintain the air-conditioning ability of an air conditioner by a method wherein the rate of change of the indoor temperature with time after the stop of running of the compressor is computed to measure the size of the air- conditioning load amount, and the number of poles of the stator winding of the compressor motor is changed according to said result.
CONSTITUTION: In the cooler, the value preset by an indoor temperature setting unit 10 and the value detected by an indoor temperature detector 8 are compared in a comparator 11, and according to said comparison result, a switch 12 is turned ON/ OFF to start/stop a compressor motor 2. In this case, when the switch 12 is turned off, the reference signal to be inputted to the comparator 11 is changed over to an ON reference signal 10a as well as a timer unit 14 is actuated. Then, after a given period of time has passed, an output is generated to turn on a switch 16, and the output of the temperature detector 8 at that time and an OFF reference signal 10b are inputted to an arithmetic device 15. The output thereof and a preset value 17a are compared 17, and according to said comparison result, a switch 13 is changed over to a two-pole terminal 13a or four-pole terminal 13b to control the number of revolutions of the motor 2.
