Description

응축수를 이용한 디젤엔진의 연료 쿨러 보조장치{Fuel cooler auxiliary device for using condensation water in diesel engine}Fuel cooler auxiliary device for using condensation water in diesel engine

본 발명은 디젤엔진의 연료 쿨러 보조장치에 관한 것으로, 보다 상세하게는 냉방장치의 작동시 발생된 저온의 응축수를 이용해 연료를 냉각시켜 줄 수 있도록 된 응축수를 이용한 디젤엔진의 연료 쿨러 보조장치에 관한 것이다.The present invention relates to a fuel cooler auxiliary device for a diesel engine, and more particularly, to a fuel cooler auxiliary device for a diesel engine using condensed water to cool fuel by using low temperature condensate generated during operation of a cooling device. will be.

일반적으로 차량은 여러 가지 기후나 주행 조건에서도 탑승자에게 쾌적한 환경을 유지하고, 동시에 글래스의 흐림이나 서리 등을 방지하여 운전자의 시계를 확보하고 안전 운행에 기여하기 위하여 공조장치가 구비되어 있다.In general, the vehicle is equipped with an air conditioning device to maintain a comfortable environment for the occupant even under various weather conditions and driving conditions, and at the same time to prevent the blurring and frost of the glass to secure the driver's watch and contribute to safe driving.

이러한, 공조장치는 엔진의 동력을 전달받아 구동되는 압축기에 의하여 압축된 냉매와 열교환되어 냉기 상태로 실내에 유입됨으로써 자동차 실내를 냉방하는 냉방장치와, 엔진의 냉각수가 히터 코어를 거쳐 엔진으로 복귀하는 과정에서 냉각수와 열교환되어 온기 상태로 실내에 유입됨으로써 자동차의 실내를 난방하는 난방장치를 포함하게 된다.The air conditioner is a heat exchanger that cools a vehicle interior by heat exchange with a refrigerant compressed by a compressor driven by an engine power and is introduced into a room in a cold state, and the coolant of the engine returns to the engine via a heater core. Heat exchanged with the cooling water in the process is introduced into the room in a warm state to include a heating device for heating the interior of the car.

여기서, 상기 냉방장치는 도 1에 도시된 바와 같이 냉매가 압축기(1)에서 압축되어 응축기(2)를 통해 외기에 의해 냉각·액화된 후 리시버앤드드라이어(3)를거치면서 수분이나 먼지가 제거된 상태로 팽창밸브(4)로 흘러 들어간 다음, 이어 상기 팽창밸브(4)에서 저압의 증발기(5)내로 분무되면서 급격한 팽창을 통해 증발되어 증발기(5)에 형성된 핀을 통해서 주위의 공기로부터 열을 빼앗아 냉각을 하게 된다.Here, the cooling device is a refrigerant is compressed in the compressor (1) as shown in FIG. Flows into the expansion valve (4), and then is sprayed into the low-pressure evaporator (5) in the expansion valve (4) and evaporated through rapid expansion and heat from the surrounding air through the fins formed in the evaporator (5) It takes away and cools down.

이어, 상기 증발기(5)에 의해 열을 빼앗겨 냉각된 공기를 블로어유니트(6)를 이용해 실내에 분출하여 냉방하게 되고, 이때 저압의 가스로 된 냉매는 다시 압축기(1)로 흡입되어 압축되는 과정을 반복적으로 수행하게 된다.Subsequently, the air taken away by the evaporator 5 is cooled by blowing the cooled air into the room using the blower unit 6, and at this time, the refrigerant made of low pressure gas is sucked back into the compressor 1 and compressed. Will be performed repeatedly.

그러나, 이와 같은 냉방장치의 냉동 사이클이 순환될 때 팽창되는 냉매를 이용해 주위로부터 열을 빼앗는 증발기(5)는 그 기능상 차가운 응축수(10℃ 이하)가 반드시 생성되는 바, 이 응축수는 냉방장치의 작동시 악취와 차량의 실내 공기 오염을 발생시키는 문제가 있어 별도의 배출수단(10)을 이용해 외부로 배출시켜주게 된다.However, the evaporator 5 which draws heat from the surroundings by using a refrigerant that expands when the refrigeration cycle of the air conditioner is circulated is functionally produced with cold condensate (10 ° C. or lower). There is a problem that causes the bad smell and indoor air pollution of the vehicle is discharged to the outside using a separate discharge means (10).

여기서, 상기 배출수단(10)은 도 2에 도시된 바와 같이 냉기와 온기가 흐르는 통로를 형성하는 덕트라인(8)상에서 히터코어(7)와 블로워유니트(6)사이로 위치된 증발기(5)쪽에 연결되어 응축수를 뽑아 낸다.Here, the discharge means 10 is located on the side of the evaporator 5 located between the heater core 7 and the blower unit 6 on the duct line 8 forming a passage through which cold and warm air flow, as shown in FIG. Connected to drain condensate.

즉, 상기 배출수단(10)은 도 3에 도시된 바와 같이 응축수를 모으도록 증발기(5)에 연결되어 덕트라인(8)밖으로 배출된 드레인라인(11)과, 이 드레인라인(11)에 끼워져 응축수를 차량 외부로 배출하는 드레인호스(12) 및 상기 드레인라인(11)이 인출된 덕트라인(8)부위를 감싸면서 누수를 차단하는 스폰지(Sponge)재질로 이루어진 기밀부재(13)로 이루어진다.That is, the discharge means 10 is connected to the evaporator 5 to collect the condensate as shown in Figure 3 drain line 11 is discharged out of the duct line 8, and the drain line 11 is fitted A drain hose 12 for discharging the condensate to the outside of the vehicle and the airtight member 13 made of a sponge (Sponge) material to block leakage while surrounding the portion of the duct line 8 with which the drain line 11 is drawn out.

그러나, 디젤 엔진의 경우 고압의 연료펌프를 사용해 연료를 공급하는 특성상 특정 조건 예를 들면, 저속·고 부하 조건에서는 연료온도가 급 상승해 이를 낮추기 위해 통상 연료쿨러라는 별도의 장치를 사용하게 되는데, 이와 같이 연료의 온도를 낮추기 위해 차량의 냉방장치 가동시 반드시 발생되는 10℃ 이하의 차가운 응축수를 외부로 버리고 연료쿨러 만을 사용하게 되면 전체적인 효율성 측면에서 바람직하지 못한 단점이 있게 된다.However, in the case of diesel engines, a fuel pump is used to supply fuel using a high-pressure fuel pump. For example, in a low speed and high load condition, a fuel temperature rises rapidly and a separate device called a fuel cooler is usually used. As such, if the cold condensate of 10 ° C. or less generated necessarily when operating the air conditioner of the vehicle is lowered to the outside and using only the fuel cooler, there is an undesirable disadvantage in terms of overall efficiency.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 외부로 버려지는 차가운 응축수를 연료쿨러쪽으로 보내 연료쿨러의 성능을 향상시킴은 물론 전체적인 효율성을 향상함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-mentioned problems, and has an object of improving the overall efficiency as well as improving the performance of the fuel cooler by sending cold condensed water discarded to the fuel cooler.

상기와 같은 목적을 달성하기 위한 본 발명은, 차실내의 냉방을 위해 냉매를 이용해 작동되는 냉방장치의 증발기에서 발생된 응축수를 덕트라인으로부터 배출시키는 배출수단과, 이 배출수단을 통해 덕트라인밖으로 배출된 응축수를 연료쿨러로 분사시켜 연료 온도를 저하시키는 공급수단 및 이 공급수단을 연료온도에 따라 구동시키는 콘트롤러로 이루어진 것을 특징으로 한다.The present invention for achieving the above object, the discharge means for discharging the condensed water generated in the evaporator of the cooling device operated by the refrigerant for cooling in the cabin from the duct line, and discharged out of the duct line through the discharge means And a supply means for injecting the condensed water into the fuel cooler to lower the fuel temperature and a controller for driving the supply means according to the fuel temperature.

이하 본 발명의 작동을 첨부된 도면을 참조로 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 냉방장치의 작동에 따라 압축기(1)와, 응축기(2), 리시버앤드드라이어(3), 팽창밸브(4) 및 증발기(5)사이를 순환하는 과정에서 열을 빼앗아 주변 공기를 냉각하는 냉매의 작용에 의해 상기 증발기(5)부위에 생성된 차가운 응축수(10℃ 이하)가 배출수단(10)을 통해 공급수단(20)쪽으로 모은 후, 엔진으로 공급되는 연료의 온도를 모니터링(Monitoring)하는 콘트롤러(23)를 통해 연료쿨러(30)쪽으로 공급되어 연료의 온도를 저하시켜주게 된다.According to the present invention, in the process of circulating between the compressor (1), the condenser (2), the receiver and dryer (3), the expansion valve (4) and the evaporator (5) according to the operation of the air conditioner to cool the ambient air Cooling condensate (10 ° C or less) generated in the evaporator (5) by the action of the refrigerant is collected through the discharge means 10 toward the supply means 20, and monitoring the temperature of the fuel supplied to the engine (Monitoring ) Is supplied to the fuel cooler 30 through the controller 23 to lower the temperature of the fuel.

즉, 상기 공급수단(20)은 냉방장치의 작동시 증발기(5)부위에서 발생된 응축수를 배출수단(10)의 드레인라인(11)에 끼워진 드레인호스(12)를 통해 보관용기(21)에 모아 저장한 후, 저장된 응축수를 콘트롤러(23)의 제어신호를 통해 연료쿨러(30)쪽으로 보내게 된다.That is, the supply means 20 is the condensed water generated in the evaporator 5 during the operation of the cooling device to the storage container 21 through the drain hose 12 fitted in the drain line 11 of the discharge means (10). After collecting and storing, the stored condensate is sent to the fuel cooler 30 through the control signal of the controller 23.

이때, 상기 콘트롤러(23)는 엔진으로 공급되는 연료온도를 모니터링해 즉, 도 5에 도시된 바와 같이 연료온도가 70℃ 이상인지 여부를 판단해 만약, 70℃ 이상인 경우 상기 보관용기(21)에 구비된 펌프(22)로 제어신호를 보내 70℃ 이하로 될 때까지 펌프(22)를 구동시키게 된다.At this time, the controller 23 monitors the fuel temperature supplied to the engine, that is, as shown in FIG. 5 to determine whether the fuel temperature is 70 ℃ or more, if the 70 ℃ or more in the storage container 21 By sending a control signal to the provided pump 22 to drive the pump 22 until it is 70 ℃ or less.

At this time, when the amount of condensed water collected in the storage container 21 increases, It is discharged to the outside by the external discharge line 21 ′ provided at the top to maintain a proper level at all times.

이상 설명한 바와 같이 본 발명에 의하면, 냉방장치의 증발기에서 발생된 10℃ 이하의 차가운 응축수를 증발기에 연결된 배출수단을 통해 응축수를 공급받아 저장한 후 연료온도에 따라 연료를 냉각하는 연료쿨러쪽으로 분사시키게 되고 이로 인해 연료쿨러의 성능과 전체적인 효율성 및 차량 성능등을 향상할 수 있는 효과가 있게 된다.As described above, according to the present invention, cold condensate water of 10 ° C. or less generated by the evaporator of the air conditioner is supplied to the fuel cooler for cooling the fuel according to the fuel temperature after storing the condensed water through the discharge means connected to the evaporator. This has the effect of improving the performance of the fuel cooler, overall efficiency and vehicle performance.
