An air conditioner including an indoor unit housing; an indoor heat exchanger configured to exchange heat with air flowing into the indoor unit housing; a compressor configured to compress a refrigerant for a cooling operation or a heating operation performed by the air conditioner; a four-way valve configured to switch a circulation direction of the refrigerant based on whether the air conditioner is to perform the cooling operation or the heating operation; a first blower fan located in the indoor unit housing and configured to blow heat-exchanged air out of the indoor unit housing; a second blower fan located in the indoor unit housing at a higher position than the first blower fan and configured to blow heat-exchanged air out of the indoor unit housing; and a processor electrically connected to the compressor, the four-way valve, the first blower fan, and the second blower fan, and configured to, during the heating operation, adjust a rotational speed of the first blower fan to be higher than a rotational speed of the second blower fan.

Air conditioner and controlling method thereof

An air conditioner including a sensor kit. The air conditioner includes: a cabinet including a first side having a first through hole and a second side having a second through hole; a pipe formed to pass through the first through hole; a sensor kit provided on the second side; and a controller to be electrically connected to the sensor kit, wherein the sensor kit includes: a sensor configured to sense a pollution level of outside air; and a cover formed to cover the second through hole on the second side, and fixing the sensor.

Air conditioner

The present disclosure is to reduce a blowing resistance while securing a mechanical strength of a fan guard. An outdoor unitincludes a housingin which an air discharge port X is formed on an upper wall, a blowing fandisposed inside the housingto correspond to the air discharge port X, and a fan guardconfigured to cover the blowing fan, wherein the fan guardincludes a plurality of annular ribsdisposed to be spaced apart from each other in a radial direction of the blowing fan, and radial ribsconfigured to connect a plurality of the annular ribs, and wherein the radial ribsare formed such that free endsthereof are bent in the same direction in a cross section orthogonal to a stretching direction and a pair of opposing piece portionsincluding each of the free endsare in surface contact with each other.

Outdoor unit, air conditioner, fan guard, and method of manufacturing fan guard

An air conditioner is disclosed. The disclosed air conditioner can comprise: a housing having an inflow port and a discharge port; a partition disposed inside the housing so as to divide the inside of the housing into a first space at the inflow port side and a second space at the discharge port side, and having at least one opening for allowing the first space and the second space to communicate; at least one blower unit disposed in the first space, and including a duct, which passes through the opening so as to protrude toward the second space and discharges the air of the first space to the second space; and a heat exchanger disposed in the second space.

A double suction fan includes first and second rings spaced at a predetermined distance apart from and in parallel to each other, an intermediate plate disposed between the first and second rings and including a shaft hole, a plurality of first blades disposed between the first ring and the intermediate plate, a plurality of second blades disposed between the second ring and the intermediate plate, and first and second rotating hubs disposed on both side surfaces of the intermediate plate, wherein each of the first and second rotating hubs is formed of a plurality of hub plates which are disposed perpendicular to the intermediate plate around the shaft hole, and wherein the plurality of hub plates are formed to evenly distribute air introduced through the first and second rings in a longitudinal direction of the plurality of first and second blades when the intermediate plate rotates.

Double suction fan and air conditioner having the same

An air conditioner system is disclosed. The air conditioner system includes: a compressor; a four-way valve configured to provide a refrigerant circulation path depending on an operation mode of the air conditioner system; a blocking valve disposed between the compressor and the four-way valve; a circulation line configured to provide a path for introducing a refrigerant discharged from the compressor back into the compressor, when the blocking valve is in a closed state; and a controller configured to control the blocking valve based on a pressure of the refrigerant discharged from the compressor.
