An air conditioner includes a housing having a suction port and a discharge port, a main fan configured to draw air into the housing through the suction port and discharge air from the housing through the discharge port, an auxiliary fan configured to draw, into the housing, air discharged by the main fan and a controller configured to control a rotational speed of the auxiliary fan to change a direction in which air is discharged from the housing.

Air conditioner and method of controlling the same

Disclosed is an air conditioner to prevent deterioration of cooling or heating performance caused by re-introduction of cooling or heating air into a heat exchanger. The air conditioner includes a housing including an air discharge plate having a plurality of holes and an outlet, a heat exchanger located inside the housing, a blower fan configured to blow air heat-exchanged with the heat exchanger toward the air discharge plate or the outlet, a blade rotating between a guide position to guide a direction of air blown from the blower fan and discharged through the outlet and a closing position to close the outlet, wherein the blade includes a first blade and a second blade spaced apart from the first blade and configured to guide air blown from the blower fan toward the air discharge plate when the first blade is located at the closing position.

Air conditioner

An air conditioner (AC) indoor unit includes a housing having an inlet and an outlet; a heat exchanger arranged inside the housing; a blower fan for sucking in air at the inlet to be subject to heat exchange with the heat exchanger, and discharging the heat-exchanged air out of the outlet; and an air flow control device for controlling an air flow discharged from the outlet by sucking in air around the outlet. The AC indoor unit may control the direction of a discharged air flow without a conventional blade structure, thereby increasing an amount of discharged air, reducing circulation noise, and enabling design differentiation.

A transceiver arrangement for a smart antenna system of a mobile communication base station is disclosed. A receiving apparatus comprises N array antennas, N AFEUs for down-converting each of signals which are received from the N array antennas into N different frequencies, respectively, N:1 power combiner for combining the converted N signals into one signal, a wideband transceiver for down-converting the combined signal into a base frequency band, a wide band analog-to-digital converter for converting the down-converted signal into a digital signal, N digital filters for dividing the digital signal into N different digital signals and L beam forming modules for receiving one by one the N digital signals divided by each of N digital dividing means and for forming adaptive beam, wherein L is the number of subscribers. A transmitting apparatus comprises L beam forming modules for L subscribers, N signal adders for adding N different signals provided by each of the beam forming modules, N digital modulators for up-converting the signal added by each of the signal adders into different frequencies, respectively, a digital signal combiner for combining signals modulated in the frequency by the N digital modulators into a digital signal, a wide band digital-to-analog converter for converting the digital signal combined by the digital signal combiner into a analog signal, a wide-band transceiver for up-converting in the frequency the analog signal converted by the wide band digital-to-analog converter, a 1:N power divider for dividing a output signal of the wide-band transceiver to N signals, equally, N antenna front-end units (AFEUs), each of AFEUS for converting one of the N signals divided by the 1:N power divider into a transmission frequency, and N array antennas for transmitting a signal from each of the antenna front-end units (AFEUs).
