ABSTRACT:
A cooling/warming control system of an air-conditioner comprises a transmitting portion and a receiving portion for radiating ultra-sonic waves from the air-conditioner to a room wall surface and receiving the ultra-sonic pulses reflected therefrom using a number of ultra-sonic wave sensors. A microcomputer calculates the time interval from the moment the radiation of the ultra-sonic pulses are transmitted until the reflecting wave pulses are received, measures the room area or volume and compares the measurement with the previous set area or volume, determines the magnitude of the cooling/warming load and then controls the load operating system connected thereto in order to operate loads in multiple stages according to the room temperature.
