Abstract

A noise control method of an air conditioner is provided to decrease the noise in a cooling operation by differentiating the operation time of a compressor and the blowing fan. A noise control method of an air conditioner differentiates the operation time of a compressor by the increase of the inside temperature from the operation time of a blowing fan. The noise control method of the air conditioner operates the compressor after the predetermined time(5 seconds) when operating the blowing fan. In the noise control method of an air conditioner, the inside temperature goes down and the compressor is turned off and the blowing fan of an inside device drives at lowest rpm, when first operating the air conditioner as an automatic cooling operation. When the inside temperature goes up, the blowing fan of the inside device drives at the predetermined rpm driver set. After checking the time from the moment the blowing fan operates, the compressor turned on after passing at 5 seconds.

본 발명은 공기 조화기의 소음 제어 방법에 관한 것으로서, 더욱 상세하게는 압축기와 송풍팬을 시간차를 두어 구동시킴으로써 냉방 운전시 갑자기 소음이 커져서 사용자가 놀라는 것을 방지하고자 순차적으로 소음을 발생시켜 소비자에게 좀 더 쾌적함을 줄 수 있도록 한 공기 조화기 소음 제어 방법에 관한 것이다. The present invention relates to a noise control method of an air conditioner, and more particularly, by driving the compressor and the blowing fan at a time difference, in order to prevent the user from being surprised by a sudden increase in noise during cooling operation, the user sequentially generates noise to the consumer. The present invention relates to an air conditioner noise control method to provide more comfort.

일반적으로 공기조화기는 실내공기를 쾌적한 상태로 유지하게 하는 장치로서, 흔히 냉방장치 또는 에어컨 등으로 불리워진다. 이와 같은 공기조화기는 일정한 공간 내에서 인간이 활동하기에 알맞은 온도, 습도 및 기류분포 등을 조절하고, 동시에 공기 속의 먼지 등을 제거하는 기능을 갖는다.In general, an air conditioner is a device for keeping indoor air in a comfortable state, and is often called a cooling device or an air conditioner. Such an air conditioner has a function of controlling temperature, humidity, and air flow distribution suitable for human activity in a certain space, and at the same time removing dust in the air.

한편, 쾌적한 실내온도는 인간의 감각에 의한 것으로 그 기준이 각 개인마다 서로 상이하나, 통상 여름철에는 외기와 내기의 기온차가 5~6℃ 정도로 실내온도 25~29℃, 습도 60~70% 정도가 바람직하고, 겨울철에는 실내온도 18~21℃, 습도 55~70% 정도가 바람직하다고 알려져 있다.On the other hand, comfortable indoor temperature is based on human sensation, and the standard is different for each individual, but in summer, the temperature difference between outside and bet is about 5 ~ 6 ℃, and the room temperature is 25 ~ 29 ℃, and humidity is about 60 ~ 70%. Preferably, in winter, it is known that the room temperature is 18 ~ 21 ℃, humidity is about 55 ~ 70%.

이와 같은 공기 조화기의 원리는 통상의 냉동기, 냉장고처럼 액체가 증발할 때 주위에서 열을 빼앗는 열교환 작용의 냉동사이클을 이용하는 것으로, 통상 이 냉동사이클의 냉매로는 저온에서도 증발하기 쉬운 액체가 사용된다.The principle of such an air conditioner is to use a refrigeration cycle having a heat exchange action that takes heat away from the liquid when the liquid evaporates, such as a conventional refrigerator or a refrigerator, and a refrigerant that is easily evaporated even at a low temperature is used as a refrigerant of the refrigeration cycle. .

도 1 은 일반적인 공기조화기의 블럭구성도로서, 실내기(10), 실내 열교환기 (11), 송풍팬(12), 실외기(20), 압축기(21), 실외 열교환기(22), 냉각팬(23), 모세관(24), 마이컴(30), 실내온도센서(31), 자동운전키(32), 온도설정키(33), 풍량설정키(34)로 이루어진다.1 is a block diagram of a general air conditioner, which includes an indoor unit 10, an indoor heat exchanger 11, a blower fan 12, an outdoor unit 20, a compressor 21, an outdoor heat exchanger 22, and a cooling fan. 23, the capillary tube 24, the microcomputer 30, the room temperature sensor 31, the automatic operation key 32, the temperature setting key 33, the air volume setting key 34.

이러한 공기조화기는 사용자가 자동운전키(32), 온도설정키(33), 풍량설정키(34)를 이용하여 원하는 명령을 선택하고, 실내 온도센서(31)는 현재의 실내온도를 검출한다. 마이컴(30)은 상기한 자동운전키(32), 온도설정키(33), 풍량설정키(34)로부터 입력된 사용자의 선택명령과, 실내 온도센서(31)로부터 검출된 실내온도를 각각 입력받고, 이 입력에 따라 압축기(21), 송풍팬(12) 및 냉각팬(23) 등의 구동상태를 제어한다.The air conditioner selects a desired command by the user using the automatic operation key 32, the temperature setting key 33, and the air volume setting key 34, and the room temperature sensor 31 detects the current room temperature. The microcomputer 30 inputs the user's selection command input from the above-described automatic operation key 32, the temperature setting key 33, and the air volume setting key 34, and the indoor temperature detected from the indoor temperature sensor 31, respectively. The drive state of the compressor 21, the blower fan 12, the cooling fan 23, etc. is controlled according to this input.

여기서, 마이컴(30)에 의하여 압축기(21)가 동작하면, 이 압축기(21)에서는 상온의 냉매를 고온, 고압으로 압축하고, 이 압축된 냉매는 실외 열교환기(22)로 유입되고 냉각팬(23)으로부터 송풍되는 실외공기와 열교환되어 냉매가 가지고 있는 열을 외부로 방출한다. Here, when the compressor 21 is operated by the microcomputer 30, the compressor 21 compresses the refrigerant at room temperature to high temperature and high pressure, and the compressed refrigerant is introduced into the outdoor heat exchanger 22 and the cooling fan ( Heat exchanged with outdoor air blown from 23) releases heat of refrigerant to the outside.

이와 같이, 실외 열교환기(22)를 거쳐 열교환된 저온, 고압의 액냉매는 모세관(24)을 거치면서 감압되어 저온, 저압의 상태로 실내 열교환기(11)에 유입된다. 이 실내 열교환기(11)에서의 냉매는 송풍팬(12)으로부터 송풍되는 실내공기와 열교환되고 실내공기가 가지고 있는 열을 흡수하여 상온으로 변환된다. 따라서 실내에는 냉매에 의해 열을 빼앗긴 차가운 바람이 송풍되므로 실내가 냉방되는 것이다.As such, the low-temperature and high-pressure liquid refrigerant heat-exchanged through the outdoor heat exchanger 22 is decompressed while passing through the capillary tube 24, and is introduced into the indoor heat exchanger 11 in a low-temperature and low-pressure state. The refrigerant in the indoor heat exchanger (11) exchanges heat with the indoor air blown from the blower fan (12), absorbs the heat of the indoor air, and converts it to room temperature. Therefore, the room is cooled because the cold wind is deprived of heat by the refrigerant is blown.

여기서, 사용자가 자동운전키(32) 밍 온도설정키(33)를 통해 소정의 목표온도를 설정하여 자동운전을 시킬 경우, 마이컴(30)은 압축기(21)를 적절히 온/오프시켜 실 내온도가 상기한 목표온도의 범위 내에서 조절되도록 한다.Here, when the user sets the predetermined target temperature through the automatic operation key 32 and the dimming temperature setting key 33 to perform automatic operation, the microcomputer 30 properly turns on / off the compressor 21 to allow room temperature. Is adjusted within the range of the target temperature.

도 2 는 종래의 공기 조화기의 구동과정을 나타낸 순서도이다.2 is a flowchart illustrating a driving process of a conventional air conditioner.

도시된 바와 같이, 종래의 공기 조화기의 구동과정은 최초 사용자가 공기 조화기가 온(S10)시킨 후, 풍량설정키(34)나 온도설정키(33), 및 자동운전키(32)를 통해 풍량을 포함한 희망 온도와 풍향 등을 설정(S12)하면, 설정된 풍량으로 희망온도까지 냉난방이 실행(S14)된다.As shown, the driving process of the conventional air conditioner is the first user after the air conditioner is turned on (S10), through the air volume setting key 34 or the temperature setting key 33, and the automatic operation key 32 If the desired temperature, the wind direction, and the like including the air volume are set (S12), cooling and heating are performed to the desired temperature at the set air volume (S14).

이와 같이 냉난방이 완료되면, 특히 풍량은 최약풍으로 변경(S16)되는데, 이와 같이 최약풍으로 변경되는 것은 희망온도에 도달하여 더 이상의 냉난방이 필요없으므로 소음이 적은 최약풍으로 변경되는 것이다. When the air conditioning is completed in this way, in particular, the amount of air is changed to the weakest wind (S16). Thus, the weakest wind is changed to the weakest wind because it reaches the desired temperature and requires no further air conditioning.

이후, 실내온도센서(31)가 실내온도 변화를 계속 체크하여 실내온도 변화에 따른 냉난방이 필요한 지를 확인(S18)하여 냉난방이 필요하지 않으면 풍량을 최약풍으로 계속 유지하고, 냉난방이 필요하면 사용자가 기 설정한 풍량으로 냉난방을 실행한다.Thereafter, the indoor temperature sensor 31 continuously checks the indoor temperature change and checks whether air conditioning is required according to the indoor temperature change (S18). If the air conditioning is not required, the air temperature is kept in the weakest wind. Perform air conditioning and heating at the preset air volume.

특히, 자동 냉장 운전에 압축기(21)가 오프일 때는 실내기의 송풍팬(12) rpm이 최약풍으로 운전하고 실내온도의 상승으로 인한 압축기(21) 온시 실내 송풍팬(12)을 설정풍량으로 변경하여 냉방한다. 이때, 공기 조화기에 따른 소음 발생 시간을 나타내는 그래프를 나타낸 도 3 에 도시된 바와 같이, 실내 송풍팬(12) rpm 상승에 의한 소음증가와 냉매유음에 의한 소음이 동시에 발생하여 불쾌감을 준다는 문제점이 있었다.In particular, when the compressor 21 is turned off during automatic refrigerating operation, the blowing fan 12 rpm of the indoor unit is operated at the weakest wind, and the indoor blowing fan 12 is changed to the set air volume when the compressor 21 is turned on due to the increase in the indoor temperature. Cool by At this time, as shown in Figure 3 showing a graph showing the noise generation time according to the air conditioner, there is a problem that the noise caused by the increase in the noise caused by the cooling of the cooling fan 12 at the same time the air blowing fan 12 has a problem that gives a discomfort. .

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 압축기와 송풍팬을 시간차를 두어 구동시킴으로써 냉방 운전시 감성적인 소음을 저감할 수 있도록 한 공기 조화기 소음 제어 방법을 제공하는 데 그 목적이 있다. An object of the present invention is to provide an air conditioner noise control method capable of reducing emotional noise during cooling operation by driving a compressor and a blowing fan at a time difference. .

전술한 목적을 달성하기 위해 안출된 본 발명의 구성은 다음과 같다. 본 발명은 공기 조화기의 자동 냉방 운전에서의 소음 제어 방법에 있어서, 압축기의 오프시 실내온도의 상승으로 인한 상기 압축기의 구동 시점을 송풍팬의 구동 시점과 다르게 구동시키는 것을 특징으로 한다.The configuration of the present invention devised to achieve the above object is as follows. The present invention is characterized in that the noise control method in the automatic cooling operation of the air conditioner, the driving time of the compressor due to the increase in the room temperature when the compressor is off is driven differently from the driving time of the blowing fan.

여기서, 송풍팬 구동 후 소정 시간이 경과한 후에 상기 압축기를 구동시키는 것을 특징으로 하고, 상기한 소정 시간은 5초인 것을 특징으로 한다.The compressor may be driven after a predetermined time elapses after driving the blower fan, and the predetermined time may be 5 seconds.

이하에서는 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

도 4 는 본 발명에 따른 공기 조화기의 소음 제어 방법을 나타낸 순서도이고, 도 5 는 본 발명에 따른 공기 조화기의 소음 발생 시간을 나타낸 그래프이다.4 is a flowchart illustrating a noise control method of an air conditioner according to the present invention, and FIG. 5 is a graph showing a noise generation time of the air conditioner according to the present invention.

참고로, 본 발명의 실시예에서 종래의 기술과 동일한 부분에 대해서는 동일한 도면부호를 부여하고, 그 상세한 설명은 생략한다.For reference, in the embodiments of the present invention, the same reference numerals are given to the same parts as in the prior art, and detailed description thereof will be omitted.

본 발명에 따른 공기 조화기의 소음 저감 방법은 도 4 에 도시된 바와 같이, 최초 자동냉방운전으로 구동(S10)시키는 경우, 실내 온도가 낮아져 압축기(21)가 오프(S20)되면, 이와 함게 실내기의 송풍팬(12) rpm이 최약풍으로 운전(S30)하게 된다.The noise reduction method of the air conditioner according to the present invention, as shown in Figure 4, when the first drive in the automatic cooling operation (S10), the room temperature is lowered and the compressor 21 is turned off (S20), together with the indoor unit The blowing fan 12 rpm is driven in the weakest wind (S30).

이후, 실내 온도가 다시 상승(S40)하면, 실내기의 송풍팬(12) rpm을 사용자가 기 설정한 설정풍량으로 변경하여 구동(S50)시키고, 이 송풍팬(12)이 구동한 시점부터 시간을 체크(S60)하여 소정 시간(t) 바람직하게는 최소 5초 이상 경과(S70)하면, 압축기(21)를 온(S80)시킨다.Thereafter, when the room temperature rises again (S40), the air blowing fan 12 rpm of the indoor unit is changed to a preset air volume set by the user to drive (S50), and the time from the time when the air blowing fan 12 is driven is increased. When it checks (S60) and passes the predetermined time (t), preferably minimum 5 seconds or more (S70), the compressor 21 is turned on (S80).
