あった。Conventional heating operation using a wall-mounted air conditioner for heating and cooling has the disadvantage that warm air accumulates in the upper part of the room, leaving the living space and feet of the room cold even if the heating capacity or airflow speed is improved. Was. In order to overcome this drawback, a floor-standing air conditioner with air conditioning/heating and moon-shaped air conditioners was developed, and a floor-standing air conditioner with two air outlets, one above the other, was also developed. The upper and lower component power type of the floor-standing air conditioning/heating and moon-shaped air conditioner is performed using one blower, and when blowing air into the upper and lower sections, a part of the blower casing is opened or a duct is installed from the upper air outlet. Since the structure is such that a part of the blown air is guided to the lower outlet and blown out, the temperature of the blown air, the amount of air, and the speed of the air are insufficient, and a sufficient temperature distribution effect cannot be obtained.

の改善を図ることができなかった。Additionally, a structure is known in which a wall-mounted cooling-only air conditioner is provided with two air outlets at the top and bottom, and one blower is provided at each air outlet to manually control various operating modes. However, since it is a wall-mounted type and is designed exclusively for cooling, it has not been possible to improve the indoor air temperature distribution and the feeling of heating, which are the above-mentioned drawbacks during heating operation.
