As the outdoorcentrifugal fan 34 is driven, the indoor air is sucked into thecase 10 positioned at the outdoor side through the outdoorair suction port 16 formed at both lateral surfaces of thecase 10 thus to be heat-exchanged while passing through theoutdoor heat exchanger 32. The heat-exchanged air is discharged to outdoors through the outdoorair discharge port 18 formed at the rear side of thecase 10. - Herein, since the outdoor
centrifugal fan 34 is applied to theoutdoor unit 30 in the same manner that the indoorcentrifugal fan 24 is applied to theindoor unit 20, an air volume lowering can be prevented even if a flow channel resistance is increased. According to this, a suction space into which the outdoor air is sucked is reduced thereby to reduce the entire size of the compressor. - In case that the condensing
water dispersing unit 70 is applied to the outdoorcentrifugal fan 34, condensing water is generated on the surface of theoutdoor heat exchanger 32 by a temperature difference. The condensing water falls down thus to be collected into the lower portion of thecase 10. Then the condensing water is dispersed to theoutdoor heat exchanger 32 by the condensingwater dispersing unit 70 thereby to lover the temperature of theoutdoor heat exchanger 32. - That is, when the outdoor
centrifugal fan 34 is rotated, thedispersion ring 62 connected to the outdoorcentrifugal fan 34 by the supportingring 64 is together rotated thereby to lift up the condensing water contained in the lower portion of thecase 10 and to disperse to theoutdoor heat exchanger 32. - In the window type air conditioner according to the present invention, the indoor centrifugal fan that the air volume is not lowered even if the flow channel resistance is increased is installed at the outdoor unit. According to this, the suction space inside the case positioned at the outdoor side to which the outdoor air is sucked is reduced thereby to reduce the entire size of the compressor.
- Also, the dispersion ring is installed at the outdoor centrifugal fan thus to disperse condensing water to the outdoor heat exchanger. According to this, the temperature of the outdoor heat exchanger is lowered faster thus to enhance the function of the air conditioner.
- It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
