본 발명은 차량 냉방장치의 쿨링팬 제어방법에 관한 것으로, 더 자세하게는 아이들(idle)시에 실내온도 및 냉매압력에 따라 쿨링팬의 용량을 제어할 수 있도록 한 것에 관한 것이다.The present invention relates to a method for controlling a cooling fan of a vehicle cooling apparatus, and more particularly, to controlling the capacity of a cooling fan according to an indoor temperature and a refrigerant pressure during an idle.
차량 실내는 태양, 대기, 도로 또는 엔진 등과 같이 외부 및 내부에서 가해 지는 여러 가지 열에 의해 실내좌석이나 계기류 등이 뜨거워지며, 이렇게 차내 공기가 더워지게 되면 차량 냉방장치(에어컨)를 가동하게 된다.The interior of the vehicle is heated by various heat applied from the outside and the inside, such as the sun, the atmosphere, the road, or the engine, and the interior seats and instruments are heated. Thus, when the air in the vehicle becomes hot, the vehicle air conditioner (air conditioner) is operated.
차량 냉방장치는 냉매를 압축-응축-팽창-증발시키는 과정을 반복하는 것으로, 증발과정에서 실내의 열을 빼앗음으로써 실내 온도를 낮추게 된다.The vehicle air conditioner repeats a process of compressing, condensing, expanding, and evaporating a refrigerant, thereby lowering a room temperature by depriving heat of a room during evaporation.
상기 차량의 냉방장치를 구성하는 주요부품으로는 냉매를 증발시키는 기능을 하는 증발기(Evaporator), 압축하는 압축기(Compressor) 그리고 응축하는 응축기(Condenser)와 이를 연결하는 파이프와 호스(Pipe & Hose) 등이 있다.The main components of the vehicle cooling system include an evaporator that functions to evaporate refrigerant, a compressor that compresses, and a condenser that condenses, and pipes and hoses that connect them. There is this.
본 발명은 상기 차량 냉방장치의 쿨링팬(Cooling)을 효과적으로 제어할 수 있도록 하는 제어방법에 관계하는 것으로, 종래에는 쿨링팬의 작동소음을 저감하기 위해 엔진 아이들시에 냉매압력이나 실내온도와 관계없이 쿨링팬의 용량을 주행시의 용량(예를 들면 90%)에 비해 훨씬 낮은 용량(예를 들면70%)으로 저감하였기 때문에 차량 냉방장치의 성능 저하 및 연비 저하를 유발하게 되는 문제가 있었다.The present invention relates to a control method for effectively controlling the cooling fan (Cooling) of the vehicle air conditioner, conventionally, regardless of the refrigerant pressure or room temperature during engine idle to reduce the operating noise of the cooling fan. Since the capacity of the cooling fan is reduced to a much lower capacity (for example, 70%) than the capacity at the time of driving (for example, 90%), there is a problem that the performance of the vehicle air conditioner is lowered and fuel economy is lowered.
즉, 도 1에는 두 차량에 대한 정지 및 주행 테스트에 따른 평균 패널 벤트 온도 그래프가 도시되어 있는 바, 위쪽의 차량의 아래쪽 차량의 비해 벤트 온도가 높음을 볼 수 있으며, 이는 위쪽 차량의 경우 아이들시 팬속도가 저감되어 콘덴싱 용량이 감소되었기 때문이다.That is, Figure 1 shows the average panel vent temperature graph according to the stopping and driving test for the two vehicles, it can be seen that the vent temperature is higher than the lower vehicle of the upper vehicle, which is idle when the upper vehicle This is because the fan speed is reduced and the condensing capacity is reduced.
그리고 도 2에는 도 1의 아래쪽 차량의 정지 및 주행 테스트에 따른 쿨링팬 전압제어 그래프가 도시되어 있고, 도 3에는 동 차량의 후레쉬 모드 테스트 그래프가 도시되어 있는 바, 아래쪽 차량은 아이들시 쿨링팬 속도가 감소되었고, 아이들시 콘덴싱 용량을 증가하기 위해서는 쿨링팬의 용량을 높여야 함을 의미한다.2 shows a cooling fan voltage control graph according to the stopping and driving test of the lower vehicle of FIG. 1, and a flash mode test graph of the vehicle is shown in FIG. 3. Is reduced, it means that the cooling fan capacity must be increased in order to increase the condensing capacity when idle.
본 발명은 상기와 같은 종래의 실정을 감안하여 안출한 것이며, 그 목적이 엔진 아이들시에 냉매압력이나 실내온도에 따라 쿨링팬의 용량을 제어함으로써 차량 냉방장치의 성능향상 및 연비 향상을 도모할 수 있도록 하는 차량 냉방장치의 쿨링팬 제어방법을 제공하는 데에 있는 것이다.The present invention has been devised in view of the above-described conventional situation, and its purpose is to improve the performance and fuel efficiency of a vehicle cooling apparatus by controlling the capacity of a cooling fan according to refrigerant pressure or room temperature during engine idle. It is to provide a cooling fan control method of a vehicle cooling system.
본 발명은 상기의 목적을 달성하기 위하여 아이들시 냉매의 압력이 일정수준이하이면 팬소음의 저감을 위하여 쿨링팬의 용량을 작게 하고, 아이들시 냉매의 압력이 일정수준이상이거나 실내온도가 일정온도이상이면 에어컨 성능 및 연비향상을 위해 쿨링팬 용량을 크게 하는 등 아이들시 냉매의 압력 및 실내온도에 따라 쿨링팬의 용량을 제어하는 것을 특징으로 하며, 이하 그 구체적인 기술내용을 첨부도면에 의거하여 더욱 자세히 설명하면 다음과 같다.In order to achieve the above object, the present invention provides a low cooling fan capacity for reducing fan noise when the refrigerant pressure is lower than a predetermined level, and the refrigerant pressure is higher than or equal to a certain level or the indoor temperature is higher than or equal to a certain temperature. The cooling fan's capacity is controlled according to the refrigerant's pressure and room temperature during idle, such as increasing the cooling fan's capacity to improve air conditioner performance and fuel efficiency.The following detailed technical details will be given based on the accompanying drawings. The explanation is as follows.
도 1에는 본 발명의 작동흐름도가 도시되어 있는 바, 본 발명의 차량 냉방장치의 쿨링팬 제어방법은 차속이 OKPH인지를 판단하는 단계; 차속이 0KPH이면 에어컨 냉매압력과 실내온도를 확인하는 단계; 냉매압력이 설정압력이상이거나 실내온도가 설정온도이상이면 쿨링팬을 최대용량(예를 들면 90%)으로 작동시키는 단계; 냉매압력이 설정압력이하이면 쿨링팬을 저감용량(예를 들면 70%)으로 작동시키는 단계;로 이루어진 것이다.Figure 1 shows the operating flow chart of the present invention, the cooling fan control method of the vehicle cooling apparatus of the present invention comprises the steps of determining whether the vehicle speed is OKPH; Checking the air condition refrigerant pressure and room temperature if the vehicle speed is 0 KPH; Operating the cooling fan at a maximum capacity (eg, 90%) if the refrigerant pressure is above the set pressure or the room temperature is above the set temperature; If the refrigerant pressure is less than the set pressure to operate the cooling fan at a reduced capacity (for example 70%).
본 발명에 있어서 차속이 0KHP일 때에 쿨링팬의 용량을 결정하는 냉매의 설 정압력은 250psi로 할 수 있으며, 설정온도는 30℃로 할 수 있는 바, 본 발명에 있어서 설정압력 및 설정온도는 예측 가능한 범위내에서 변경될 수 있음은 물론이다.In the present invention, when the vehicle speed is 0KHP, the set pressure of the refrigerant for determining the capacity of the cooling fan may be 250 psi, and the set temperature may be 30 ° C. In the present invention, the set pressure and the set temperature are predicted. Of course, it can be changed within the possible range.
한편 본 발명에 있어서 차속이 0KPH 이상인 경우에 쿨링팬은 기존과 마찬가지로 블로바이수온과 에어컨압력, 차속정보로 구성되는 별도의 쿨링팬 로직 테이블에 의해 작동된다.Meanwhile, in the present invention, when the vehicle speed is 0 KPH or more, the cooling fan is operated by a separate cooling fan logic table composed of blow-by water temperature, air conditioner pressure, and vehicle speed information as in the past.
상기와 같이 구성된 본 발명에 있어서는 차속이 0KHP인 경우라도 냉매의 압력이 설정압력보다 높을 때, 그리고 실내온도가 설정온도보다 높을 때에 쿨링팬의 용량을 크게 함으로써 냉각 성능과 차량 연비를 향상시킬 수 있게 되며, 차속이 0KHP이고 냉매의 압력이 설정압력보다 낮을 때는 쿨링팬의 용량을 작게 하여 쿨링팬 작동소음을 저감할 수 있게 된다.In the present invention configured as described above, even when the vehicle speed is 0KHP, when the refrigerant pressure is higher than the set pressure and when the indoor temperature is higher than the set temperature, the cooling fan capacity is increased to improve cooling performance and vehicle fuel economy. When the vehicle speed is 0KHP and the pressure of the refrigerant is lower than the set pressure, the cooling fan operation noise can be reduced by reducing the capacity of the cooling fan.
이상에서 설명한 바와 같이 본 발명은 아이들시 냉매의 압력 및 실내온도에 따라 쿨링팬의 용량을 제어하는 것으로, 본 발명에 의하면 아이들시에도 냉각 성능 및 연비가 저하되지 않도록 할 수 있게 되어 차량 냉방장치의 기능성 및 상품성을 크게 향상시킬 수 있게 되는 등의 효과를 얻을 수 있게 된다.As described above, the present invention controls the capacity of the cooling fan according to the pressure and the room temperature of the refrigerant during idling. According to the present invention, it is possible to prevent the cooling performance and fuel economy from being lowered even during idling. The effect of being able to greatly improve the functionality and the merchandise can be obtained.
