Description

에어컨 작동 소음 저감 방법 {Slugging noise reducing method}Air conditioning operating noise reduction method {Slugging noise reducing method}

본 발명은 에어컨 작동 소음 저감 방법에 관한 것으로, 좀더 상세하게는 차량의 엔진 시동후 초기에 에어컨을 작동시키면 발생하는 슬러깅 소음(slugging noise)을 저감시키기 위한 에어컨 작동 소음 저감 방법에 관한 것이다.The present invention relates to a method for reducing air conditioning operation noise, and more particularly, to a method for reducing air conditioning operation noise for reducing slugging noise generated when operating the air conditioner at the beginning after engine start of a vehicle.

일반적으로, 일교차가 큰 계절 즉, 봄, 가을에 차량을 장시간 방치하면 에어컨 냉매가 기체에서 액체로 변환되어 차량 엔진의 시동후 초기에 에어컨을 작동시키면 드르륵 하는 소음(slugging noise)이 발생하게 되어, 사용자의 불만을 일으키는 요인이 되고 있다.In general, when the vehicle is left for a long time in a large crossover season, that is, spring and autumn, the air conditioner refrigerant is converted from gas to liquid, and when the air conditioner is operated at the early stage after the engine is started, slitting noise is generated. It is a cause of user dissatisfaction.

즉, 기존 차량의 에어컨 시스템은 엔진이 시동된 상태에서 에어컨 스위치가 “온”되는 경우에만 에어컨을 작동시키도록 되어 있어, 차량 엔진의 시동후 초기에 에어컨을 작동시킴에 따라 발생하는 슬러깅 소음을 감소시키기 위한 대책 방안이 없었다.In other words, the air conditioner system of the existing vehicle is configured to operate the air conditioner only when the air conditioner switch is “on” while the engine is started, thereby suppressing the slugging noise generated by operating the air conditioner after the engine start. There was no countermeasure to reduce it.

이에, 본 발명은 상기한 바와 같은 문제점들을 해소하기 위해 안출된 것으로, 차량의 엔진 시동시에 에어컨 컴프레서를 일정시간 동안 작동시켜서, 차량 엔진의 시동후 초기에 에어컨을 작동시킴에 따라 발생하는 슬러깅 소음을 저감시킬 수 있는 에어컨 작동 소음 저감 방법을 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the problems described above, by operating the air conditioner compressor for a predetermined time at the start of the engine of the vehicle, slugging generated by operating the air conditioner early after the start of the vehicle engine It is an object of the present invention to provide a method for reducing air conditioning operation noise that can reduce noise.

상기한 바와 같은 목적을 달성하기 위한 본 발명에 따른 에어컨 작동 소음 저감 방법은, 엔진 시동시에 소정의 에어컨 컴프레서 구동조건을 만족하는지를 판단하는 단계와, 상기 에어컨 컴프레서 구동조건을 만족하면 에어컨 컴프레서를 소정시간 동안만 구동시키는 단계를 포함하여 구성된 것을 특징으로 한다.According to an aspect of the present invention, there is provided a method for reducing air conditioner operation noise according to the present invention, including determining whether a predetermined air conditioner compressor driving condition is satisfied at engine start-up, and when the air conditioner compressor driving condition is satisfied, It characterized in that it comprises a step of driving only for time.

도 2는 본 발명에 따른 에어컨 작동 소음 저감 방법을 설명하기 위한 타이밍도이다.2 is a timing diagram for explaining a method for reducing air conditioning operation noise according to the present invention.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명에 따른 에어컨 작동 소음 저감 방법을 설명하기 위한 순서도이다.1 is a flowchart illustrating a method for reducing air conditioning operation noise according to the present invention.

상기 도 1에 도시된 바와 같이, 단계(S1)에서는, 차량의 엔진 시동이 걸렸는지를 판단하여, 시동이 걸렸으면 단계(S2)를 수행한다. 즉, 차량에 구비된 컨트롤러가 시동스위치가 “온”되었는지를 판단하는 것이다.As shown in FIG. 1, in step S1, it is determined whether the engine engine is started, and if the engine is started, step S2 is performed. That is, the controller provided in the vehicle determines whether the start switch is “on”.

상기 단계(S2)에서는, 외기 온도가 기준온도, 바람직하게는 13.2도 이상인가를 판단하여 13.2도 이상이면 단계(S3)를 수행하고, 13.2도 보다 작으면 단계(S7)를 수행한다. 즉, 차량에 구비된 외기온도센서에 의해 감지된 외기 온도를 콘트롤러가 입력받아 외기 온도가 13.2도 이상인지를 판단하는 것이다.In step S2, it is determined whether the outside temperature is a reference temperature, preferably 13.2 degrees or more, and if step 13.3 degrees or more, step S3 is performed, and if smaller than 13.2 degrees, step S7 is performed. That is, the controller receives the outside air temperature sensed by the outside air temperature sensor provided in the vehicle and determines whether the outside air temperature is 13.2 degrees or more.

상기 단계(S3)에서는 배터리전압이 기준전압, 바람직하게는 10V 이상인지를 판단하여, 10V 이상이면 단계(S4)를 수행하고, 10V 보다 낮으면 단계(S7)를 수행한다. 즉, 차량에 구비된 전압센서에 의해 감지된 배터리 전압을 컨트롤러가 입력받아 배터리 전압이 10V 이상인지를 판단하는 것이다.In step S3, it is determined whether the battery voltage is a reference voltage, preferably 10V or more, and if step 10V or more, step S4 is performed, and if step 10 is lower than step 10, step S7 is performed. That is, the controller receives the battery voltage sensed by the voltage sensor provided in the vehicle to determine whether the battery voltage is 10V or more.

상기 단계(S4)에서는 에어컨 스위치가 “오프”되었는지를 판단하여 에어컨 스위치가 “오프”되었으면 단계(S5)를 수행하고, 에어컨 스위치가 “온”되었으면 단계(S7)를 수행한다. 즉, 차량에 구비된 컨트롤러가 에어컨 스위치가 “오프”되었는지를 판단하는 것이다.In the step S4, it is determined whether the air conditioner switch is "off", and if the air conditioner switch is "off", step S5 is performed, and if the air conditioner switch is "on", step S7 is performed. That is, the controller provided in the vehicle determines whether the air conditioner switch is “off”.

상기 단계(S5)에서는 냉각수온도와 외기온도의 차이값이 기준차온도, 바람직하게는 10.5도 이하인지를 판단하여, 10.5도 이하이면 단계(S6)를 수행하고, 10.5도 보다 크면 단계(S7)를 수행한다. 즉, 차량에 구비된 냉각수온센서와 외기온도센서에 의해 감지된 냉각수 온도 및 외기 온도를 컨트롤러가 입력받아 냉각수 온도와 외기 온도의 차이가 10.5도 이하인지를 판단하는 것이다.In step S5, it is determined whether the difference between the coolant temperature and the outside temperature is a reference difference temperature, preferably 10.5 degrees or less, and if step 10.5 degrees or less, step S6 is performed, and if greater than 10.5 degrees, step S7 Perform That is, the controller receives the coolant temperature and the outside temperature detected by the coolant temperature sensor and the outside temperature sensor provided in the vehicle to determine whether the difference between the coolant temperature and the outside temperature is 10.5 degrees or less.

상기 단계(S6)에서는 에어컨 컴프레서를 소정시간, 바람직하게는 0.3초 동안만 구동시키고, 상기 단계(S7)에서는 에어컨 컴프레서를 작동시키지 않는다. 즉, 차량에 구비된 콘트롤러가 자체에 구비된 타이머를 사용하여 0.3초 동안만 에어컨 구동 릴레이를 “온”시킴으로써 에어컨 컴프레서를 0.3초 동안 구동시키는 것이다.In step S6, the air conditioner compressor is driven only for a predetermined time, preferably 0.3 seconds, and in step S7, the air conditioner compressor is not operated. That is, the controller provided in the vehicle drives the air conditioner compressor for 0.3 second by "turning on" the air conditioner driving relay for only 0.3 second using the timer provided in the vehicle.

상기한 바와 같은 본 발명에 따른 에어컨 작동 소음 저감 방법은, 도 2에 도시된 바와 같이, 시동스위치가 “온”되는 시점에서, 외기 온도가 기준 온도(13.2도) 이상이고, 배터리 전압이 기준 전압(10V) 이상이며, 에어컨 스위치가 “오프”되어 있고, 냉각수 온도와 외기 온도의 차가 기준차온도(10도) 이하이면 0.3초 동안 에어컨 컴프레서를 구동시키는 것이다.In the air conditioner operating noise reduction method according to the present invention as described above, as shown in Figure 2, when the start switch is "on", the outside temperature is above the reference temperature (13.2 degrees), the battery voltage is the reference voltage If the air conditioner switch is “off” and the difference between the coolant temperature and the outside temperature is less than the reference difference temperature (10 degrees), the air conditioner compressor is driven for 0.3 seconds.

이상에서 설명한 바와 같이 본 발명에 따르면, 차량의 엔진 시동시에 에어컨 컴프레서를 일정시간 동안 작동시켜서, 차량 엔진의 시동후 초기에 에어컨을 작동시킴에 따라 발생하는 슬러깅 소음을 저감시킬 수 있다.As described above, according to the present invention, by operating the air conditioner compressor for a predetermined time when starting the engine of the vehicle, it is possible to reduce the slugging noise generated by operating the air conditioner early after the start of the vehicle engine.
