風は吹き出せない。Conventional structure and its problems Traditionally, ceiling-mounted air conditioners (hereinafter referred to as air conditioners) have an air intake section in the center and discharge sections on the left and right sides of the air conditioner. If the height of the product is lowered by placing the containers on almost the same horizontal plane, air can only blow in two directions: left and right.

点が生じてくる。However, in the case of an air conditioner, when considering restrictions on installation locations and equalization of indoor temperature distribution, it is not sufficient to blow air in two directions as described above. Therefore,
For this purpose, it is conceivable to form blow-off portions in four directions on the decorative panel to provide blow-off in four directions. However, the single-suction sirocco fan has a characteristic in the blowout flow from its impeller, and the casing is set so that the blowout flow direction is circumferential with respect to the rotation direction. There is. Correspondingly, when a heat exchanger is arranged to obtain a four-directional blowout flow, it is necessary to make the blowout flow hit the heat exchanger as perpendicularly as possible. This is because if the fan's airflow is blown directly onto the heat exchanger at an angle, the pressure loss will increase, the loss of the fan motor will increase, abnormal wind noise will occur, and the efficiency of the heat exchanger will also decrease. A disadvantage arises in that it is reduced.

空調機を得んとするものである。OBJECTS OF THE INVENTION The present invention addresses these facts and provides an efficient air flow through a heat exchanger by using single-suction sirocco fans and optimizing the arrangement of the short-form exchanger. ,
It is an object of the present invention to provide an air conditioner that efficiently blows out air-conditioned air from blow-off parts in four directions of a main body.

くする等の効果がある。Effects of the Invention As is clear from the above explanation, in the ceiling-mounted air conditioner according to the present invention, the long side of the L-shaped heat exchanger disposed around the fan is adjacent to the guide, and the short side is opposite. Therefore, all of them are arranged perpendicular to the tangential direction of the rotation direction of the fan, making it possible to blow out air-conditioned air in four directions. Also, only in this arrangement, when using a sirocco fan, it is possible to blow air vertically onto the heat exchanger, which improves the efficiency of the heat exchanger. This has the effect of improving the efficiency of the fan motor by reducing pressure loss, and eliminating abnormal noise caused by blowing air obliquely onto the heat exchanger.
