Therefore, the outdoor unit chambers 100 and 102 are adjacent to each other. According to the most remarkable characteristic of the present invention, discharge directions of heat-exchanged waste air discharged from the outdoor unit chambers 100 and 102 are distant directions from the most adjacent outdoor units (arrow X directions of Fig. 3 ).
  • heat-exchanged waste air discharged from one outdoor unit is rarely re-sucked to a suction unit of the outdoor unit, a suction unit of an adjacent outdoor unit, or a suction unit of an outdoor unit on the upper floor. That is, when fresh outdoor air is not sucked through the suction unit but high temperature waste air discharged from the outdoor unit or other outdoor units is re-sucked through the suction unit, heat exchange efficiency of the air-cooled condenser is inevitably reduced, which can be solved by the present invention.
  • FIG. 4 illustrates one preferable example of the detailed means for achieving the above objects.

  • the outdoor unit discharges heat-exchanged waste air in the distant direction from the most adjacent outdoor unit, by using a centrifugal cooling fan (more preferably, sirocco cooling fan) having a relatively high discharge air volume, preferably over 6m/s. Even when a high-storied building wind or contrary wind blows in the arrow Z directions, waste air discharged from the outdoor unit is hardly re-sucked to the outdoor unit itself or the adjacent outdoor unit.
  • a centrifugal cooling fan more preferably, sirocco cooling fan
  • Fig. 5 illustrates one example of the installation structure of the outdoor units in accordance with the present invention.
  • an outdoor unit 10a of A must be installed more adjacently to a partition between A and B, but is shown more distant from the partition for convenience's sake.
  • the discharge direction of the sirocco cooling fan 40a of A is opposite to the discharge direction of the sirocco cooling fan 40b of B.
  • a rotation direction of a sirocco cooling fan motor of A must be opposite to a rotation direction of a sirocco cooling fan motor of B.
  • the sirocco cooling fan having its orifices face the up/down direction was used as the centrifugal cooling fan.
  • the centrifugal cooling fan even if different shapes of fans are used, if air guide units for inducing discharged air in the distant directions from the most adjacent outdoor units are installed, the discharge directions of heat-exchanged waste air from the most adjacent outdoor units can be maintained opposite to each other merely by controlling the directions of the air guide units.
  • the louver blades of the discharge unit can be formed in the longitudinal direction. That is, when heat-exchanged waste air is discharged, it can be induced by the louver blades in the distant direction from the most adjacent outdoor unit.
  • an open direction of the louver blades of A is opposite to an open direction of the louver blades of B.
  • the outdoor unit where the suction area is formed in the lower portion and the discharge area is formed in the upper portion has been explained.
  • the same principle can also be applied to an outdoor unit where a suction area is formed in the upper portion and a discharge area is formed in the lower portion.
  • Fig. 6 illustrates an outdoor unit where a suction area and a discharge area are formed in the left and right sides.
  • discharge directions of heat-exchanged waste air are X directions, namely distant directions f rom the most adjacent outdoor u nits
  • a nd suction directions of fresh outdoor air are Y directions. Accordingly, waste air discharged from each outdoor unit is hardly re-sucked to suction units of the outdoor units themselves, the adjacent outdoor units on the same floor, or the adjacent outdoor units on different floors.
  • a centrifugal cooling fan preferably a sirocco cooling fan is u sed a s a cooling fan.
  • FIG. 6 can obtain the same effects as the outdoor unit where the discharge area and the suction area are installed in the up/down direction. Still referring to Fig. 6 , when the suction unit of one outdoor unit chamber is adjacent to the suction unit of the most adjacent outdoor unit chamber, the above effects can be maximized.
  • orifices of the sirocco cooling fan In order to omit a special air guide unit for controlling discharge directions, orifices of the sirocco cooling fan must face top and bottom surface units of an outdoor unit casing. However, in this case, the orifices do not face the suction area but are vertical to the suction area side.
  • the sirocco cooling fan was used as one example of the centrifugal cooling fan.
  • a turbo fan which is another example of the centrifugal cooling fan is used, the same principle can be applied. That is, waste air can be discharged in the distant directions from the adjacent outdoor units, by installing turbo fans having their orifices face the up/down direction in the adjacent outdoor units, and maintaining rotation directions of the turbo fans opposite to each other.
  • centrifugal cooling fan having its orifices face the up/down direction has been exemplified.
  • waste air can also be discharged in the distant direction from the most adjacent outdoor unit, by using a centrifugal cooling fan having its orifices face both side units, and installing an appropriate shape of air guide unit.
  • waste air can be discharged in the distant direction from the most adjacent outdoor unit, by using a different shape of fan such as an axial fan instead of using the centrifugal cooling fan, and installing an appropriate shape of air guide unit.
  • the air guide unit is installed between the cooling fan and the louver frame so that it cannot be externally shown for better appearance.
  • the outdoor unit structure can minimize reduction of heat exchange efficiency between the adjacent outdoor units in the apartment building in which the plurality of front suction/discharge type outdoor units for the air conditioner are installed. As a result, interferences are minimized between the front suction/discharge type outdoor units installed in each house of the high-rise apartment building or commercial building.
