Abstract

PURPOSE:To prevent dew condensation at a wall surface of a room opposing to a side surface of a main body of the unit by a method wherein air blowing ports arranged at both side surfaces of a casing of the main body of the unit is clogged by a blind cap in response to a hanging position of the main body of the unit. CONSTITUTION:In case that a blowing port 4 at the right side surface is placed near a wall surface 35 of an interior 34 and a main body 1 of the unit is hung and fixed, a blank cap 17 for the blowing port 5 at the left side surface is removed while the blank cap 17 for the blowing port 4 at the right side surface is closed, the cold air is blown at the front surface blowing port 3 and the left side blowing port 5. Also in this case, the interior air passed from the blowing grills 10 and 10 through the filter 13 into the nozzle port 7 is blown to the entire circumference by a turbo fan 6. However, since the blowing port 4 at the right side surface is closed by the blank cap 17, the blowing pressure is increased, the cold air is blown from the two blowing ports 3 and 5 at a high speed, a reaching distance of the cold air is extended and the room 34 is substantially uniformly cooled every nook and corner in it.

(When being blown out from the 5+, the drain water that is generated in the heat exchanger (8) and drips is pushed into the drain pan (9) by the discharge pressure of the turbo fan (6) and is immediately transferred to the unit. It will be discharged outside without a break (1).

In addition, if the unit body (1) is suspended and fixed with the air outlet (4) on the right side close to the wall surface C351 of the indoor room 04 as shown in the plan view shown in FIG. As shown in Figure 5 (B), if you leave the air outlet (4) on the right side blocked with the blind cover (lη) and remove the blind cover αη from the air outlet (5) on the left side, the air will look like the solid line arrow shown in Figure 5 (B). Cold air is blown out from two sides: the front air outlet (3) and the left side air outlet (5).At this time, the filter α is also
The indoor air that passes through the nozzle port (7) and is sucked into the nozzle port (7) is discharged in the circumferential direction by the turbo fan (6), but the right side air outlet (4) is blocked by the blind cover αη. As a result, the discharge pressure increases and cold air is blown out at a high speed from the air outlets (31f5) on the two sides, and the reach of the cold air is longer than in the case of Fig. 5 (a), reaching almost every corner of the room (3i) evenly. - The air conditioner is cooled to -.

In addition, the blind cover a7) is made of foamed Sunarol resin that has heat insulating properties, so there is no risk of cooling and condensation around the right side air outlet (4). ) so it is not visible and does not spoil the aesthetic appearance.

In addition, when the unit main body (1) is suspended and fixed in a long and narrow room (toward) as shown in the plan view shown in Fig. 5 (c), both side air outlets (41 (51) are closed with blind lids (17). If you leave the stems in place and leave them at ℃, cold air will be blown out from the front air outlet (3) at a higher speed as shown by the solid line arrow in the same figure, extending the reach even further, reaching almost evenly to the back of the room (branch). It is cooled to

A small amount of cold air is blown out from the front of 5).

In this way, by appropriately changing the size of the blind cover Q according to the hanging position of the unit body (1) and adjusting the opening area of the air outlet (43 (51)), the room is cooled approximately evenly.

(G) Effects of the Invention According to the present invention, air is blown out from the sides of the unit body by blocking the blind lids that are girder air outlets provided on both sides of the casing of the unit body depending on the hanging position of the unit body. It is possible to solve the conventional problems in which cold air is biased toward the walls of the room or the walls are cooled and dew forms on the walls.

In addition, by blocking the air outlet with the blind lid, the velocity of the air blown from at least the front air outlet increases and the reach of the blown air is extended, so that the room can be cooled uniformly.

Moreover, since the blind lid and the air outlet are covered by the air outlet grill and cannot be seen, the appearance is not spoiled, and the blind lid can prevent damage to the wind direction changing blades provided on the air outlet grill during transportation. .

In particular, by molding the foamed sterol resin with a blind lid, there is no risk of condensation adhering to the air outlet on the same day that it is blocked, and the blind lid can be easily attached by simply pushing it into the air outlet. can.
