Abstract

According to the present invention, the air conditioner enables a more comfortable air conditioning without being affected by the rotational noise generated when the blowing fan is rotated by variably controlling the driven fan fan speed according to the ambient noise during the operation of the air conditioner. The present invention relates to a blower fan control method and method, the present invention relates to a sound control unit for collecting the noise of the surrounding environment in a blower control device of the air conditioner for controlling the blowing amount of the indoor unit while determining whether the silent operation during air conditioning And a sound pressure level setting unit for setting the predetermined reference sound pressure, and a sound pressure determination unit for comparing and determining the noise input from the sound source sound collection unit with the reference sound set by the sound pressure level setting unit.

Claims (8)

A blower fan control apparatus for an air conditioner that controls the amount of air blower of an indoor unit during air conditioning, wherein the blower controller collects ambient environmental noise and compares the collected noise with a predetermined predetermined noise to set a noise level. Air conditioning, characterized in that consisting of a sensor 11 and a microcomputer (5) for setting and controlling the number of revolutions of the blower fan as a controlled signal for controlling the noise signal input from the noise detector (11) Blower fan control device. 2. The sound detector according to claim 1, wherein the noise detector (11) includes a sound source sound collector (8) for collecting noise in an ambient environment, a sound pressure level setting unit (9) for setting the predetermined reference sound pressure, and the sound source sound collector And a sound pressure determining unit (10) configured to compare the noise inputted from (8) with the reference noise set by the sound pressure level setting unit (9). A blowing fan control method of an air conditioner that controls the air volume of an indoor unit during air conditioning, wherein the noise of the surrounding environment is collected, the location of the collected noise is judged, and arbitrarily selected from the set air volume according to the determined noise location. Blow fan speed setting step 350 to set the rotation speed of the blowing fan by adding or subtracting the set air volume, and in the state to set the rotation speed of the blowing fan according to the noise in the blowing fan speed setting step 350 If the set air flow rate is the same as the blow fan fan speed, the set air flow step 360 of setting the air flow rate to the set maximum allowable rotation speed, and the user set air flow in the set air flow step 360, the standard fan speed If it is not the same as that of the silent operation while determining whether the silent operation, the blowing fan control unit 315 for controlling the air volume of the blowing fan by the user set air flow rate Air blowing fan control method of the air conditioner according to Gong. A blowing fan control method of an air conditioner which controls the air volume of an indoor unit during air conditioning, wherein the noise of the surrounding environment is collected and the place of the noise of the collected noise is determined and the set air volume is determined according to the determined noise place. Blowing fan speed setting step 350 to set the rotation speed of the blowing fan by adding or subtracting the arbitrarily set amount of air, and the rotation speed of the blowing fan is set according to the noise in the blowing fan speed setting step 350 and the user's setting Air flow fan If it is equal to the standard rotation speed, the set air flow step 360 to set the air flow rate to the set maximum allowable rotation speed, and if the user set wind volume in the set air flow step 360 is not equal to the standard fan speed, Quiet operation setting step (370) for setting the silent operation while determining whether the silent operation, and blower fan for controlling the air volume of the blower fan with the set air volume in the state of setting the silent operation according to the noise in the silent operation setting step (370) Blowing fan control method of an air conditioner, characterized in that the control stage 315 made. 5. The method of claim 4, wherein the setting fan speed step 350 determines the noise of the surrounding environment according to the large noise place, the normal noise place, and the small noise place to add or subtract the rotation speed of the blower fan according to the determined noise. Blowing fan control method of an air conditioner, characterized in that. 5. The method of claim 4, wherein the setting of the blowing fan rotational speed (350) increases the rotational speed of the blowing fan as the noise of the surrounding environment increases. The method of claim 4, wherein the silent operation setting step 370 is to set the predetermined amount of air according to the determined state while determining whether the ambient noise is a large noise place, a normal noise place, or a small noise place. Blowing fan control method of an air conditioner characterized in that. The blower fan control of the air conditioner according to claim 4, wherein the static air blowing fan control step 370 is configured to subtract any amount of air so that the set air volume is set smaller as the noise of the surrounding environment becomes smaller.
