At the same time, the other part is horizontally installed inside the suction part 11a, and the control box may be installed inside the other side of the condenser 20 and 30.

As such, the shape and installation structure of the condenser 20, 30 can be configured in various ways.

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

First, when the air conditioner is operated, the compressor is operated according to the cooling load and some or all of the pair of centrifugal fans 42 and 52 are operated to operate, and the refrigerant is the compressor and the condensers 20 and 30. ), While passing through the electronic expansion valve and the evaporator, while being compressed, condensed, expanded under reduced pressure, and evaporated, the outdoor air is blown to the condensers 20 and 30 to exchange heat with the refrigerant passing through the condensers 20 and 30. On the other hand, while indoor air is blown to the evaporator side, the cooling operation is performed by exchanging heat with the refrigerant passing through the evaporator.

Here, when only one of the pair of centrifugal fans 42 and 52 is operated because the cooling load is relatively small, external air flows into the suction part 11a of the outdoor unit case through the suction area 107a. Next, while passing all around the pair of condenser 20, 30 and the heat exchange action with the refrigerant circulating therein.

Next, the external air passes through the operating centrifugal fan 52 and the fan housing 54 in which the fan is built, and flows into the suction hole 54a of the fan housing and passes through the centrifugal fan 52. It is discharged again to the outside through the discharge hole 54b of the fan housing.

At this time, the rotation direction is adjusted so as to blow air in the opposite direction to the centrifugal fan 42 in which the operating centrifugal fan 52 is stopped, and the fan housing 54 in which the operating centrifugal fan 52 is built-in is stopped. Since it is formed to guide the discharge flow to the opposite direction to the centrifugal fan 42, the blowing air efficiency and heat exchange efficiency by preventing the external air passing through the operating centrifugal fan 52 to flow back to the stationary centrifugal fan 42 side Can be increased.

On the other hand, when the cooling load is relatively large and a pair of centrifugal fans 42 and 52 are both operated, external air flows into the suction part 11a of the outdoor unit case through the suction area 107a, and then a pair While passing through all of the condenser (20,30) of the heat exchange action with the refrigerant circulating therein.

Next, the outside air is raised and passed through a pair of centrifugal fans (42, 52) and each of the fan housings (44, 54) while being divided and flowed by the separator (70), respectively, the suction hole of the fan housing ( Not shown, it is introduced into 54a, passes through the centrifugal fans 52 and 54, and is then discharged to the outside again through the discharge holes 44b and 54b of the fan housing.

At this time, not only the pair of centrifugal fans 42 and 52 are adjusted to rotate in opposite directions, but also the respective fan housings 44 and 54 are formed to guide discharge flows in opposite directions to each other. By blowing the air blown by the 42, 52) it is possible to increase the blowing efficiency and heat exchange efficiency.

On the other hand, when an outdoor unit including a pair of centrifugal fans 42 and 52 and an outdoor unit including a pair of centrifugal fans 242 and 252 are installed in close proximity, the pair of centrifugal fans 42 and 52 are all in one direction. In addition, since a pair of centrifugal fans 242 and 252 adjacent to the outdoor unit are rotated in different directions, the air discharged from each outdoor unit may not interfere with each other, thereby increasing the blowing efficiency and the heat exchange efficiency.

The detachable air conditioner wall recessed outdoor unit according to the present invention configured as described above is provided with a louver frame in an open space of an outer wall of a commercial and / or residential building, and an outdoor unit may be fixed and installed inside the louver frame. A realistic installation structure of the wall-mounted outdoor unit for the conditioner is possible, and furthermore, the wall-mounted outdoor unit for the separate air conditioner and the outdoor unit for the separate air conditioner have a pair of condensers located on both sides inside the outdoor unit case, In addition to the condenser of the shape is installed there is an advantage that can reduce the height of the product because a pair of centrifugal fan is installed above each condenser.
