Abstract

Abstract An air conditioner includes a housing to be mounted on a wall surface in the interior of a room, an air inlet provided at an upper part of the housing, an air outlet provided at a lower part of the housing, an air passage provided in said housing so as to connect the air inlet and said air outlet to each other, a heat exchanging means and an air blowing device disposed in said air passage, and a wind direction plate provided inside an opening of the air outlet in order to change the direction of blowing of thermoregulated air out of the air outlet. An air quantity adjusting plate is provided at an end of the opening of said air outlet in order to change the area of the opening of the air outlet, whereby a sufficient air quantity is obtained regardless of the direction of ventilation of thermoregulated air to thereby perform room air-conditioning efficiently.
