換不良の判断が一定回数連続した場合には運転を
停止するようにしてなる空気調和機の制御装置。 In an air conditioner that uses a rotary four-way switching valve to switch between cooling and heating modes, the outlet temperature at the time of mode switching and the elapsed time after the compressor restarts operation after switching the mode. If a difference of more than a predetermined value is not observed between the two outlet temperatures, it is determined that the switching is defective and the rotary four-way switching valve is re-driven. A control device for an air conditioner that compares temperatures and stops operation if a switching failure is determined a certain number of times in a row.
