The discharge guide 104 is connected to the partition 72 to guide the air discharged from the blowers 54 and 55 to the discharge unit 160 on the side surface.

Looking at the operation of the present invention configured as described above are as follows.

First, when the first turbo fan 54a and the second turbofan 55a are operated in opposite directions by the control signal generated from the control box 66, the front grill 62 is opened and the indoor air is the front panel ( It is introduced into the cabinet 52 through the intake port 58a of the 58, and the air thus introduced is cooled as it passes through the heat exchanger 56.

The air cooled as described above is guided to the first turbo fan 54a and the second turbofan 55a while suppressing the generation of turbulence by the first orifice 64a and the second orifice 64b.

At this time, the intake air is not mixed with each other by the partition 72 in the process of moving air toward the first and second blowers 54 and 55 through the air guide 64, respectively, the first turbo fan It passes through the 54a and the second turbo fan 55a and is guided to the discharge part 160 side.

Here, the blowers 54 and 55 suck air through the center to discharge air in the circumferential direction, and part of the air discharged in the circumferential direction is guided by the discharge guides 102 and 104 to discharge the air. Is moved to 160.

In particular, the discharge guide 102 formed at the lower side guides the air discharged through the inclined surface 105 formed at the center side of the blower 54, 55 to the discharge unit 160 at the lower side or the side, and the discharge guide formed at the upper side. 104 guides the air discharged from the blowers 54 and 55 to the discharge portion 160 on the side through the surface 52 'formed in connection with the partition 72.

The air guided to the discharge unit 160 is discharged to the room through the discharge port 161 ′ of the discharge grill 161.

Meanwhile, the blowers 54 and 55 may be rotated in the same direction and in different directions by the control signal generated by the control box 66.

For example, when the first turbo fan 54a is rotated counterclockwise and the second turbo fan 55a is rotated clockwise, the air discharged by the turbo fans 54a and 55a is formed on both sides and The air is discharged through the discharge unit 160 positioned below, and in particular, the air discharged through the discharge unit 160 is discharged while forming wind speed and air volume of left / right symmetry.

That is, when the turbo fans 54a and 55a are rotated as described above, stronger wind is discharged through the upper ends of the discharge grills 161 formed on both sides of the cabinet 52, and the lower ends are weaker than the upper ends. The wind is discharged, and the air discharged from the discharge unit 160 provided on each of the left and right sides has left and right symmetry.

In the frame-type air conditioner and its operation method according to the present invention configured as described above, the discharge guide is installed in the cabinet and around the blower, and the air discharged from the blower is guided by the discharge guide and the partition wall installed in the cabinet. By discharging to the left / right symmetry there is an effect of air conditioning the room more uniformly and quickly.

In addition, in the frame air conditioner according to the present invention, the air discharged from the first and second blowers is symmetrically discharged in the left / right and lower directions, and the velocity and the air volume of the discharged air are uniform so that the left / right side of the frame air conditioner is uniform. There is an effect of more uniform air conditioning.

In particular, the frame type air conditioner according to the present invention is not only formed in the air volume and the wind speed of the air discharged from the top / bottom of the left / right discharge grill symmetrically, but also the air volume and the wind speed of the air discharged through the lower discharge grill is also centered on the partition wall Since it is formed symmetrically, there is an effect to more uniformly coordinate the left / right and the lower side of the frame type air conditioner.

In addition, the operation method of the frame-type air conditioner according to the present invention has the effect that the vibration of the cabinet is canceled by the rotation direction rotated left / right symmetry because the first and second blowers are rotated in opposite directions.

In addition, in the frame type air conditioner according to the present invention, since the discharge guide for guiding the air discharged from the blower to the discharge portion is formed, the discharge air in the cabinet is more efficiently flowed to the discharge portion.

In addition, in the frame type air conditioner according to the present invention, since the discharge guide formed on the upper side of the cabinet is integrally formed with the partition wall, it not only prevents the air discharged in the circumferential direction from mixing with the discharge air of the adjacent blower, but also the discharge guided by the partition wall. Air also has the effect of guiding to the discharge section on the side.
