To provide a self-cleaning method for air conditioning indoor and outdoor units.SOLUTION: A self-cleaning method for air conditioning indoor and outdoor units includes: adjusting the number of rotations of an indoor unit fan and/or an operation speed of a compressor to condense the surface of an evaporator of the indoor unit; performing a step for defrosting/drying the evaporator of the indoor unit and a condensation/frosting step for a condenser of an outdoor unit by adjusting the indoor unit fan and/or the compressor, and a four-way valve so as to form frost on the surface of the evaporator of the indoor unit; adjusting the number of rotations of the indoor unit fan so as to defrost/dry the surface of the evaporator of the indoor unit; adjusting the number of rotations of the outdoor unit fan so as to condense the surface of the condenser of the outdoor unit; adjusting the number of rotations of the outdoor unit fan so as to form frost on the surface of the condenser of the outdoor unit; and defrosting the surface of the condenser of the outdoor unit. By this invention, self-cleaning of the indoor unit and drying/bacteriostasis of the indoor unit, and self-cleaning of the outdoor unit can be achieved, and air-conditioning performance is improved, thereby helping to secure the health of a user.SELECTED DRAWING: Figure 1 【課題】本発明は、空調室内機・室外機の自己清浄方法を提供する。【解決手段】室内機の蒸発器表面を結露させるように、室内機のファンの回転数及び／又はコンプレッサの作動速度を調節することと、室内機の蒸発器表面を着霜させるように、室内機のファン、及び／又はコンプレッサ、四方弁を調節することで、室内機の蒸発器の除霜・乾燥工程及び室外機の凝縮器の結露・着霜工程を行うことと、室内機の蒸発器表面を除霜・乾燥させるように、室内機のファンの回転数を調節することと、室外機の凝縮器表面を結露させるように、室外機のファンの回転数を調節することと、室外機の凝縮器表面を着霜させるように、室外機のファンの回転数を調節することと、室外機の凝縮器表面を除霜させることと、を含む。本発明によれば、室内機の自己清浄と乾燥・静菌並びに室外機の自己清浄を実現でき、空調性能の向上が図られ、利用者の健康を確保することに役立っている。【選択図】図１
