Abstract

A method for controlling operation of an air conditioner is provided to control blowoff force or wind direction of an indoor unit in accordance with the external air temperature to reduce a vertical temperature difference of a room due to the external air temperature. An operation mode selected by a user and operation information are inputted to a control unit(S200). The control unit judges whether operation is on(S202). If so, the control unit starts operation of an indoor unit according to the selected operation mode(S204). The external air temperature of a room is inputted to the control unit(S206). The control unit compares the inputted external air temperature with a preliminarily set first reference temperature(S208). If the external air temperature is lower than the first reference temperature, the control unit increases wind velocity of an indoor fan or angles of blades(S210). If the external air temperature is not lower than the first reference temperature, the external air temperature is compared with a preliminarily set second reference temperature(S212). If the external air temperature is higher than the second reference temperature, the control unit decreases wind velocity or angles of the blades(S214).

By adjusting the air volume or the wind direction of the indoor unit (10).

즉, 동절기 등에 외기온도가 낮을수록 건물 외벽이나 창을 타고 내려오는 찬 공기의 온도가 낮아지고 바닥에 깔리는 찬 공기의 유동이 많아짐에 따라 실내공간의 외주부에 수직온도차가 크게 발생하는 경우 실내기(10)의 풍량을 늘리고 풍향범위를 넓게 조절함으로서 외주부 근처 실내공간의 수직온도차를 줄이도록 제어한다.That is, the lower the outside air temperature in winter, the lower the temperature of the cold air coming down the building walls or windows, and the more the cold air spreads on the floor, the greater the vertical temperature difference in the outer periphery of the indoor space. By increasing the wind volume and widening the wind direction range, it controls to reduce the vertical temperature difference of the indoor space near the outer circumference.

이하, 상기와 같이 구성된 공기조화기의 운전제어방법의 동작과정 및 작용효과를 설명한다.Hereinafter, an operation process and an effect of the operation control method of the air conditioner configured as described above will be described.

도 4는 본 발명에 의한 천장형 공기조화기의 운전제어방법의 동작 흐름도로서, 하나의 실외기(미도시)에 연결된 복수의 실내기(10)가 천장에 매립되는 형태로 실내공간의 다양한 위치에 설치되는 멀티 공기조화기에서 실내기(10)가 실내공간의 외주부(외벽 근처)에 설치된 경우를 예로 들어 설명한다.4 is a flowchart illustrating an operation control method of a ceiling type air conditioner according to the present invention, in which a plurality of indoor units 10 connected to one outdoor unit (not shown) are embedded in a ceiling, and installed at various positions of an indoor space. In the multi-air conditioner, the indoor unit 10 will be described as an example in which the indoor unit 10 is installed on the outer periphery (near the outer wall) of the indoor space.

먼저, 사용자가 선택하는 운전모드(예를 들어, 난방운전)와 설정온도, 설정풍량, 설정풍향 등의 운전정보가 입력부(100)를 통해 제어부(130)에 입력된다(S200).First, operation information selected by a user (for example, heating operation), operation temperature, such as a set temperature, a set wind volume, and a set wind direction, is input to the controller 130 through the input unit 100 (S200).

따라서, 제어부(130)는 운전 온인가를 판단하여(S202), 운전 온이면 선택된 난방운전모드에 따라 실내기(10)의 난방운전을 개시한다(S204).Therefore, the controller 130 determines whether the operation is on (S202), and when the operation is on, starts the heating operation of the indoor unit 10 according to the selected heating operation mode (S204).

실내기(10)의 난방운전이 개시되면, 두 개의 실내팬(24)이 설정풍량에 따라 회전하면서 흡입구(16)를 통해 실내공기가 실내기(10)내로 흡입되고, 흡입구(16)를 통해 흡입되는 실내공기의 온도와 설정온도를 비교하여 실내온도와 설정온도의 차에 따라 압축기(142)의 운전주파수를 제어하여 압축기(142)를 구동시킴으로서 난방 운전을 수행한다.When the heating operation of the indoor unit 10 starts, the indoor air is sucked into the indoor unit 10 through the suction port 16 while the two indoor fans 24 are rotated according to the set air volume, and the suction is carried out through the suction port 16. The heating operation is performed by comparing the temperature of the indoor air with the set temperature and controlling the operating frequency of the compressor 142 according to the difference between the room temperature and the set temperature to drive the compressor 142.

이때, 난방운전 중인 실내기(10)가 설치된 실내공간의 외기온도(To) 즉, 건물의 외벽온도를 외기온도감지부(120)에서 감지하여 제어부(130)에 입력한다(S206).At this time, the outside temperature (To) of the indoor space in which the indoor unit 10 is being heated, that is, the outside wall temperature of the building is sensed by the outside temperature sensing unit 120 and input to the control unit 130 (S206).

이에 따라, 상기 제어부(130)는 입력된 외기온도(To)을 미리 정해진 기준온도(T1;외기온도가 낮을 때의 기준온도)와 비교하여(S208), 외기온도(To)가 기준온도(T1)보다 작으면 외기온도(To)가 낮다고 판단하여 실내팬(24)의 풍속을 높이거나 또는 블레이드(20)의 각도를 크게 조절한다(S210).Accordingly, the controller 130 compares the input outside air temperature To with a predetermined reference temperature T1 (reference temperature when the outside air temperature is low) (S208), whereby the outside air temperature To is the reference temperature T1. If it is less than the outside temperature (To) is determined to be low to increase the wind speed of the indoor fan 24 or to adjust the angle of the blade 20 large (S210).

이와 같이, 실내팬(24)의 풍속을 높이거나 또는 블레이드(20)의 각도를 크게 조절함에 따라 실내기(10)에서 토출되는 더운 공기의 풍량을 늘리고 풍향범위를 넓게 함으로서 건물 외벽이나 창을 타고 내려오는 찬 공기의 유동을 적게 하여 외주부 근처 실내공간의 수직온도차를 줄일 수 있게 된다.As such, by increasing the wind speed of the indoor fan 24 or by greatly controlling the angle of the blade 20, the air flow rate of the hot air discharged from the indoor unit 10 is increased and the wind direction range is widened to lower the building exterior wall or window. It is possible to reduce the vertical temperature difference of the indoor space near the outer circumference by reducing the flow of cold air coming.

한편, 상기 외기온도(To)가 기준온도(T1)보다 작지 않으면 외기온도(To)를 미리 정해진 기준온도(T2;외기온도가 높을 때의 기준온도)와 비교하여(S212), 상기 외기온도(To)가 기준값(T2)보다 크면 외기온도(To)가 높다고 판단하여 실내팬(24)의 풍속을 낮추거나 또는 블레이드(20)의 각도를 작게 조절한다(S214).On the other hand, if the outside temperature (To) is not less than the reference temperature (T1) by comparing the outside temperature (To) with a predetermined reference temperature (T2; reference temperature when the outside temperature is high) (S212), the outside temperature ( If To is greater than the reference value T2, it is determined that the outside temperature To is high, and thus the wind speed of the indoor fan 24 is reduced or the angle of the blade 20 is adjusted to be small (S214).

이와 같이, 실내팬(24)의 풍속을 낮추거나 또는 블레이드(20)의 각도를 작게 조절함에 따라 실내기(10)에서 토출되는 더운 공기의 풍량을 적게 함으로서 에너지소비를 줄이고, 또한 실내기(10)에서 토출되는 더운 공기의 풍향범위를 상대적으로 좁게 함으로서 원하는 실내공간의 난방효율을 높일 수 있게 된다.As such, by lowering the wind speed of the indoor fan 24 or by adjusting the angle of the blade 20 small, the amount of hot air discharged from the indoor unit 10 is reduced to reduce energy consumption, and also in the indoor unit 10. By relatively narrowing the wind direction range of the discharged hot air it is possible to increase the heating efficiency of the desired indoor space.

이후, 입력부(100)를 통해 공기조화기의 운전정지명령이 입력되면(S216) 천 장형 공기조화기의 모든 동작을 종료한다.Thereafter, when the operation stop command of the air conditioner is input through the input unit 100 (S216), all operations of the ceiling type air conditioner are terminated.

한편, 본 발명의 실시예에서는 두 개의 토출구(18)가 형성된 실내기(10)를 예로 들어 설명하였으나, 본 발명은 이에 한정되지 않고 토출구(18)가 하나 이상 형성된 어떠한 실내기(10)에서도 본 발명과 동일한 목적 및 효과를 달성할 수 있음은 물론이다.Meanwhile, in the exemplary embodiment of the present invention, the indoor unit 10 in which two discharge ports 18 are formed has been described as an example, but the present invention is not limited thereto, and the present invention may be applied to any indoor unit 10 in which one or more discharge ports 18 are formed. Of course, the same purpose and effect can be achieved.

상기의 설명에서와 같이, 본 발명에 의한 공기조화기의 운전제어방법에 의하면, 실내기가 실내공간의 외주부에 설치된 경우 외기온도에 따라 실내기의 풍량 또는 풍향을 조절하여 외기온도로 인한 실내공간의 수직온도차를 줄임으로서 재실자의 쾌적도를 향상시킬 수 있다는 효과가 있다.As described above, according to the operation control method of the air conditioner according to the present invention, when the indoor unit is installed on the outer periphery of the indoor space, the vertical temperature difference of the indoor space due to the outdoor air temperature by adjusting the air volume or the wind direction of the indoor unit according to the outdoor air temperature By reducing the effect of improving the comfort of the occupants can be effective.
