PURPOSE:To reduce a temperature difference in a room and improve the comfortable property as well as the efficiency of cooling and heating operations, by a method wherein the transmitter of a remote controller and the main body of an air-conditioning machine are provided with first and second temperature sensors and the driving speed of an airflow direction controlling plate is controlled based on the difference between detected indoor temperatures. CONSTITUTION:Indoor temperatures T1, T2 around the transmitter 5 of a remote controller and an indoor machine 6 are detected by first and second temperature sensors 7, 14. An infrared ray signal 11, corresponding to an indoor temperature T1, is transmitted to an infrared ray receiving circuit 12 while a temperature data pick-up circuit 13 outputs temperature data to a temperature difference operating circuit 16 based on the receiving signal of the infrared ray receiving circuit 12. The temperature data, corresponding to the other indoor temperature T2 and detected by the second temperature sensor 14, is inputted into a temperature difference operating circuit 16. The temperature difference operating circuit 16 operates the temperature difference and controls the pulse width Pw of a pulse oscillating circuit 17. A motor driving circuit 21 outputs a driving signal, having the pulse width Pw, to a stepping motor 20. According to this constitution, the driving speed of an airflow direction control plate 18 is slow when the temperature difference DELTAT is small but is quick as the temperature difference DELTAT is increased sequentially whereby the indoor temperature difference between the vicinity of the transmitter 5 of the remote controller and the vicinity of an indoor machine 6 may be eliminated.
