Abstract: An air conditioner includes a case provided with openings, a heat exchanger disposed in the case, one or more fans disposed in the case, and a variation unit that is movably disposed around the fans to vary air inlet and outlet directions.

Abstract: A method of diagnosing an air conditioner and mobile terminal equipment for performing the method are provided. The method of diagnosing the air conditioner using mobile terminal equipment includes beginning diagnosis of the air conditioner, displaying a diagnostic result of the air conditioner on a screen, and displaying a countermeasure for the diagnostic result.

Abstract: An axial flow fan and an air conditioner including the axial flow fan, where the axial flow fan includes a plurality of blades. The blades include corrugated parts on ends thereof. The corrugated parts include at least one of convex portions or the concave portions.

Abstract: An air conditioning system is provided. The air conditioning system allows coolant to selectively flow through a series of bypass pipes and valves connecting an outlet of a compressor and an outlet of an expansion member. The series of bypass pipes and valves allow a defrosting function to be performed without performing a reverse cycle.

Abstract: A fan includes a hub and a plurality of blades formed on the hub with a rake angle. In an axial direction of the hub, no part of a trailing edge of any of the blades is disposed past an air outlet end of the hub at more than a distance approximately equal to 25% of a diameter of the hub.

Abstract: Provided is an indoor unit of an air conditioner. The structures of the indoor unit, such as the relationship between an inlet and an outlet, the shape of a rear guide, and the relationship between the outlet and a vane, are improved. Therefore, the airflow of the indoor unit is stable, and the noise level of the indoor unit is low.

Abstract: Provided are an axial flow fan and an air conditioner outdoor unit including the axial flow fan. The axial flow fan includes a hub and blades disposed on an outer surface of the hub. Each of the blades satisfies that a shortest distance measured from an imaginary line (L2) passing through a center of the hub to a front end of an outer edge of the blade is greater than a shortest distance measured from the imaginary line (L2) to a rear end of the outer edge of the blade. The front end of the outer edge of the blade is a leading end in a rotation direction of the blade, and the rear end of the outer edge of the blade is a trailing end in the rotation direction of the blade. Owing to the shape of the blade, noise can be reduced while increasing the flowrate of air.

Abstract: A cross-flow fan that variably maintains a distance between a blade and a fluid flow guide by varying a height of an outer edge and an air conditioner having the cross-flow fan are provided. Therefore, a noise and a peak value of a spectrum between the blade and the outer edge can be reduced.
