연료전지 차량의 공조장치{AIR CONDITIONING SYSTEM OF FUEL CELL VEHICLE}TECHNICAL FIELD [0001] The present invention relates to an air conditioning system for a fuel cell vehicle,

본 발명은 연료전지 차량의 공조장치에 관한 것으로서, 보다 상세하게는, 배터리의 전기 소모를 최소화하고서도 차실내를 효과적으로 난방할 수 있는 연료전지 차량의 공조장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air conditioning apparatus for a fuel cell vehicle, and more particularly, to an air conditioning apparatus for a fuel cell vehicle capable of effectively heating a vehicle interior while minimizing battery consumption.

최근 들어, 환경오염을 줄여줄 수 있는 친환경 차량이 다양하게 개발되고 있다. 그 일례로서, 연료전지 차량이 있다.In recent years, various environmentally friendly vehicles capable of reducing environmental pollution have been developed. As an example thereof, there is a fuel cell vehicle.

연료전지 차량은, 수소와 산소의 전기화학적 반응으로 발생된 전기를 에너지원으로 사용하는 차량으로서, 에너지 소비가 매우 적어 차량 유지비가 적게 들고, 배출가스가 없어서 대기오염을 줄여주는 친환경 무공해 차량이다.A fuel cell vehicle is an environmentally friendly, non-polluting vehicle that uses electricity generated by the electrochemical reaction of hydrogen and oxygen as an energy source. It is a low-energy consumption vehicle with a low maintenance cost and low emissions.

이러한 연료전지 차량은, 도 1에 도시된 바와 같이, 수소를 공급하는 수소탱크(1)와, 압축공기를 공급하는 공기압축기(3)와, 수소탱크(1)와 공기압축기(3)에서 공급되는 수소와 산소를 전기화학적으로 반응시켜 전기를 생산하는 연료전지 스택(Stack)(5)과, 연료전지 스택(5)에서 생산된 전기를 저장하는 배터리(7)를 구비한다. 1, the fuel cell vehicle is provided with a hydrogen tank 1 for supplying hydrogen, an air compressor 3 for supplying compressed air, and a hydrogen tank 1 for supplying hydrogen from the hydrogen tank 1 and the air compressor 3, A fuel cell stack 5 for generating electricity by electrochemically reacting hydrogen and oxygen to be supplied to the fuel cell stack 5 and a battery 7 for storing electricity produced in the fuel cell stack 5.

그리고 연료전지 차량은, 동절기 차량의 실내를 난방하기 위한 난방장치를 구비한다. The fuel cell vehicle is provided with a heating device for heating the interior of the winter vehicle.

난방장치의 일례로서, 전기히터(PTC:Positive Temperature Coefficient)히터(10)가 있다. As an example of the heating device, there is an electric heater (PTC: Positive Temperature Coefficient) heater 10.

전기히터(10)는, 배터리(7)의 전원에 의해 작동되는 것으로, 차실내로 공급되는 공기를 가열한다. 이로써, 차실내의 난방성능을 높인다.The electric heater (10) is operated by the power source of the battery (7) and heats the air supplied to the vehicle interior. As a result, the heating performance of the interior of the vehicle is enhanced.

그런데, 이러한 전기히터(10)는, 전기를 추가적으로 소모한다는 단점이 있으며, 이러한 단점 때문에 차량의 연비를 저하시킨다는 문제점이 있다. 특히, 주행에 필요한 배터리(7)의 전기를 과다하게 소모하므로, 차량의 주행거리를 현저하게 단축시키는 결과를 초래한다. However, such an electric heater 10 has a disadvantage in that electricity is additionally consumed, and there is a problem that the fuel efficiency of the vehicle is lowered due to such a disadvantage. Particularly, since the battery 7 consumes too much electric power for driving, the driving distance of the vehicle is remarkably shortened.

시험결과에 의하면, 전기히터(10)의 과다한 전기소모로 인해, 여름철 대비 겨울철의 차량 주행거리가 70∼80% 정도 수준으로 낮아지는 것으로 나타났다.According to the test results, due to excessive electric consumption of the electric heater 10, the driving distance of the vehicle in the winter compared to the summer was reduced to about 70 to 80%.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로서, 그 목적은, 난방성능을 저하시키지 않는 한도내에서 전기히터의 사용을 최소화할 수 있는 연료전지 차량의 공조장치를 제공하는 데 있다.SUMMARY OF THE INVENTION It is an object of the present invention to provide an air conditioner for a fuel cell vehicle that can minimize the use of an electric heater within a limit that does not deteriorate heating performance .

본 발명의 다른 목적은, 난방성능을 저하시키지 않는 한도내에서 전기히터의 사용을 최소화할 수 있게 구성함으로써, 전기 소모를 최소화할 수 있는 연료전지 차량의 공조장치를 제공하는 데 있다.It is another object of the present invention to provide an air conditioner for a fuel cell vehicle which can minimize the consumption of electric power by minimizing the use of the electric heater within a limit not lowering the heating performance.

본 발명의 또 다른 목적은, 전기 소모를 최소화할 수 있게 구성함으로써, 차량의 연비를 향상시킬 수 있는 연료전지 차량의 공조장치를 제공하는 데 있다.It is still another object of the present invention to provide an air conditioning apparatus for a fuel cell vehicle that can improve fuel economy of a vehicle by minimizing electricity consumption.

이러한 목적을 달성하기 위하여 본 발명은, 수소와 산소를 전기화학적으로 반응시켜 전기를 생산하는 연료전지 스택(Stack)과, 상기 연료전지 스택에서 생산된 전기를 저장하는 배터리와, 상기 배터리의 전원에 의해 작동되면서 차실내로 공급되는 공기를 가열하는 전기히터를 포함하는 연료전지 차량의 공조장치에 있어서, 차량의 상태가 절전모드일 시에 상기 전기히터를 강제로 오프(OFF)시키는 콘트롤러와; 상기 전기히터의 오프에 따른 온도 보상을 위해 상기 연료전지 스택 또는 전장품 냉각수를 난방열원으로 이용하여 차실내를 난방하는 난방수단을 더 포함하는 것을 특징으로 한다.To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a fuel cell stack including a fuel cell stack for producing electricity by electrochemically reacting hydrogen and oxygen, a battery for storing electricity produced in the fuel cell stack, A controller for forcibly turning off the electric heater when the vehicle is in a power saving mode; and a controller for controlling the electric heater to be turned off when the vehicle is in a power saving mode. And heating means for heating the interior of the vehicle using the fuel cell stack or the electric component cooling water as a heat source for temperature compensation in accordance with the turning off of the electric heater.

바람직하게는, 상기 콘트롤러는, 상기 배터리의 충전량이 미리 설정된 기준충전량 이하일 경우에, 차량의 상태가 절전모드 인 것으로 판단하여 상기 전기히터를 오프(OFF)시키는 것을 특징으로 한다.Preferably, the controller determines that the vehicle is in the power saving mode and turns off the electric heater when the charged amount of the battery is equal to or less than a preset reference charging amount.

그리고 상기 콘트롤러는, 차량의 속도가 미리 설정된 기준차속 이하일 경우에, 차량의 상태가 절전모드 인 것으로 판단하여 상기 전기히터를 오프(OFF)시키는 것을 특징으로 한다.When the vehicle speed is equal to or lower than a preset reference vehicle speed, the controller determines that the vehicle is in the power saving mode and turns off the electric heater.

본 발명에 따른 연료전지 차량의 공조장치에 의하면, 차량의 상태가 절전모드일 경우에, 전기히터를 강제로 오프시킨 다음, 이를 보상하기 위해 연료전지 스택과 전장품 냉각수를 난방의 열원으로 이용하는 구조이므로, 배터리의 전기소모를 최소화시킬 수 있으면서 난방성능의 저하현상은 최소화시킬 수 있는 효과가 있다.According to the air conditioner of the fuel cell vehicle according to the present invention, when the vehicle is in the power saving mode, the electric heater is forcibly turned off, and then the fuel cell stack and the electric component cooling water are used as heat sources for heating , The power consumption of the battery can be minimized, and the deterioration of the heating performance can be minimized.

또한, "절전모드"를 선택하여 전기히터를 필요에 따라 오프시킬 수 있는 구조이므로, 전기히터에 소모되는 전기를 필요에 따라 차단할 수 있다. 따라서, 전기히터에 의해 소모되는 전기를 최대한 절감할 수 있는 효과가 있다. Further, since the electric heater can be turned off as needed by selecting the "power saving mode ", electricity consumed in the electric heater can be blocked as needed. Therefore, the electricity consumed by the electric heater can be reduced as much as possible.

또한, 전기히터에 의해 소모되는 전기를 최대한 절감할 수 있으므로, 전기소모로 인한 차량의 연비 저하현상을 방지할 수 있는 효과가 있다.Further, since the electric power consumed by the electric heater can be reduced to the utmost, there is an effect that the fuel consumption of the vehicle can be prevented from being lowered due to the electric consumption.

또한, "절전모드"시에 차실내의 온도에 따라 전기히터를 자동으로 온,오프시키는 구조이므로, 차실내의 난방성능을 저하시키지 않는 한도내에서 전기히터의 작동을 최소화할 수 있다. 따라서, 전기 소모를 최소화할 수 있으며, 이로써, 차량의 연비를 향상시킬 수 있는 효과가 있다.In addition, since the structure in which the electric heater is automatically turned on and off according to the temperature of the interior of the vehicle in the "power saving mode ", the operation of the electric heater can be minimized without lowering the heating performance of the interior of the vehicle. Therefore, it is possible to minimize electricity consumption, thereby improving the fuel efficiency of the vehicle.

또한, 배터리의 충전량에 따라 전기히터를 자동으로 온,오프시키는 구조이므로, 배터리의 충전량을 저감시키지 않고서도 차실내를 효과적으로 난방할 수 있는 효과가 있다. In addition, since the structure is such that the electric heater is automatically turned on and off according to the charged amount of the battery, there is an effect that the vehicle interior can be effectively heated without reducing the amount of charged battery.

또한, 배터리의 충전량을 저감시키지 않고서도 차실내를 효과적으로 난방할 수 있으므로, 배터리의 충전량 저감에 따른 차량의 연비 저하현상을 방지할 수 있는 효과가 있다.In addition, since the interior of the vehicle can be effectively heated without reducing the amount of charge of the battery, it is possible to prevent the phenomenon in which the fuel consumption of the vehicle is lowered due to the reduction of the charged amount of the battery.

도 2는 본 발명에 따른 연료전지 차량의 공조장치를 나타내는 도면이다.2 is a view showing an air conditioning system of a fuel cell vehicle according to the present invention.

먼저, 본 발명의 특징부를 살펴보기에 앞서, 도 2를 참조하여 연료전지 차량에 대해 간략하게 살펴본다.First, a fuel cell vehicle will be briefly described with reference to FIG. 2 before examining the features of the present invention.

연료전지 차량은, 수소를 공급하는 수소탱크(1)와, 압축공기를 공급하는 공기압축기(3)와, 수소탱크(1)와 공기압축기(3)에서 공급되는 수소와 산소를 전기화학적으로 반응시켜 전기를 생산하는 연료전지 스택(5)과, 연료전지 스택(5)에서 생산된 전기를 저장하는 배터리(7)를 구비한다.The fuel cell vehicle includes a hydrogen tank 1 for supplying hydrogen, an air compressor 3 for supplying compressed air, and a fuel cell 3 for electrochemically reacting hydrogen and oxygen supplied from the hydrogen tank 1 and the air compressor 3 A fuel cell stack 5 for producing electricity, and a battery 7 for storing electricity produced in the fuel cell stack 5.

그리고 연료전지 차량은, 동절기에 차량의 실내를 난방하기 위한 전기히터(10)를 더 구비한다.The fuel cell vehicle further includes an electric heater 10 for heating the interior of the vehicle during the winter season.

전기히터(10)는, 배터리(7)의 전원에 의해 작동되며, 차실내로 공급되는 공기를 가열한다. 이로써, 차실내의 난방성능을 높인다.The electric heater (10) is operated by the power source of the battery (7) and heats the air supplied to the car interior. As a result, the heating performance of the interior of the vehicle is enhanced.

다음으로, 본 발명에 따른 연료전지 차량의 공조장치의 특징부를 도 2를 참조하여 상세하게 살펴보면 다음과 같다.Next, the characteristics of the air conditioning system of the fuel cell vehicle according to the present invention will be described in detail with reference to FIG.

먼저, 본 발명의 공조장치는, 연료전지 스택(5)의 냉각수를 이용한 난방장치(12)를 더 구비한다.First, the air conditioner of the present invention further includes a heating device 12 using cooling water of the fuel cell stack 5.

난방장치(12)는, 연료전지 스택(5)을 냉각시킨 고온의 냉각수를 도입하여 순환시키는 히터코어(14)와, 히터코어(14)에 공기를 불어넣는 송풍기(16)와, 히터코어(14)로부터 송풍되는 열기를 차량의 실내로 공급하는 덕트(18)로 구성된다.The heating device 12 includes a heater core 14 for introducing and circulating high temperature cooling water that has cooled the fuel cell stack 5, a blower 16 for blowing air into the heater core 14, And a duct 18 for supplying the air blown from the outdoor unit 14 to the room of the vehicle.

이러한 난방장치(12)는, 도 3에 도시된 바와 같이, 최대 65℃의 온도를 유지하는 연료전지 스택(5)의 냉각수를 도입한 후, 도입된 냉각수의 열을 방출시키고, 방출된 열기를 차량의 실내로 공급함으로써, 차량의 실내를 난방한다.3, the heating device 12, after introducing the cooling water of the fuel cell stack 5 maintaining a temperature of up to 65 DEG C, discharges the heat of the introduced cooling water, And supplies it to the interior of the vehicle, thereby heating the interior of the vehicle.

경우에 따라, 난방방치(10)는, 차량에 설치되는 각종 전장품을 냉각시키기 위한 냉각수도 도입하여 난방의 열원으로 사용할 수도 있다. 여기서, 연료전지 스택(5)과 전장품의 냉각수를 이용한 난방은 차량의 상태(절전모드 또는 정상모드)에 관계없이 차실내를 난방하도록 구성된다.As the case may be, the heating / cooling system 10 may also use cooling water for cooling various electric components installed in the vehicle, and may be used as a heat source for heating. Here, the heating using the cooling water of the fuel cell stack 5 and the electrical components is configured to heat the vehicle interior regardless of the state of the vehicle (the power saving mode or the normal mode).

참고로, 최근의 연료전지 차량은, 배터리 효율의 상승과 주변 많은 전장품으로 인해, 연료전지 스택(5)의 냉각수가 65℃정도의 온도로 상승된다. 따라서, 연료전지 스택(5)의 냉각수를 난방 열원으로 충분히 사용할 수 있으며, 이로써, 차실내를 효율좋게 난방할 수 있다.For reference, in recent fuel cell vehicles, the cooling water of the fuel cell stack 5 is raised to a temperature of about 65 占 폚 due to an increase in battery efficiency and many surrounding electrical components. Therefore, the cooling water of the fuel cell stack 5 can be sufficiently used as a heat source for heating, thereby heating the interior of the vehicle efficiently.

다시, 도 2를 참조하면, 본 발명의 연료전지 차량의 공조장치는, 차실내가 현재 난방모드인가를 감지하는 난방 감지수단(20)을 구비한다.Referring again to FIG. 2, the air conditioning system of the fuel cell vehicle of the present invention includes a heating sensing means 20 for sensing whether the interior of the vehicle is currently in a heating mode.

난방 감지수단(20)은, 차실내의 온도를 조절하기 위한 온도조절 스위치(도시하지 않음)로 구성된다. The heating sensing means 20 is constituted by a temperature control switch (not shown) for controlling the temperature of the passenger compartment.

온도조절스위치는, 차실내의 "세부 온도 설정값"을 조절하는 스위치로서, 사용자(운전자)가 차실내의 난방을 위해 특정온도 이상의 "세부 온도 설정값", 예를 들면, 27℃이상의 "세부 온도 설정값"을 설정하는 것을 감지한다. 따라서, 차실내가 현재 난방중인가를 간접적으로 감지하고, 감지된 "난방모드신호"를 후술하는 콘트롤러(50)에 입력시킨다.The temperature control switch is a switch for controlling the "detailed temperature set value" of the vehicle interior. The temperature control switch is a switch for allowing the user (driver) to set the "detailed temperature set value" Temperature setting value " Accordingly, it indirectly detects whether the interior of the vehicle is currently heating, and inputs the detected "heating mode signal" to the controller 50 described later.

한편, 난방 감지수단(20)의 다른 예로서, 온도조절도어 액츄에이터(22)의 인가전압을 감지하는 인가전압감지센서(도시하지 않음)가 있다.As another example of the heating sensing means 20, there is an applied voltage sensing sensor (not shown) for sensing the applied voltage of the temperature-controlled door actuator 22.

도어액츄에이터 인가전압감지센서는, 냉,난방단수에 따라 변화되는 온도조절도어 액츄에이터(22)의 인가전압을 감지하는 센서로서, 온도조절도어 액츄에이터(22)의 인가전압을 감지함으로써 차실내가 난방중인가를 간접적으로 감지하는 역할을 한다.The door actuator applied voltage detection sensor senses the voltage applied to the temperature control door actuator 22 which changes according to the number of cooling and heating stages and detects the voltage applied to the temperature control door actuator 22, It indirectly detects authorization.

즉, 온도조절도어 액츄에이터(22)는, 도 4에 도시된 바와 같이, 냉방단수가 높아짐에 따라 인가전압이 점차 작아지고, 난방단수가 높아짐에 따라 인가전압이 점차 커지게 된다. 따라서, 온도조절도어 액츄에이터(22)의 인가전압을 감지하면, 차실내가 현재 난방중인가를 감지할 수 있게 된다.That is, as shown in FIG. 4, as the number of cooling stages increases, the temperature of the temperature control door actuator 22 gradually decreases as the applied voltage gradually increases. As the number of heating stages increases, the applied voltage gradually increases. Accordingly, when the voltage applied to the temperature control door actuator 22 is sensed, it is possible to detect whether the interior of the vehicle is currently heated.

바람직하게는, 도어액츄에이터 인가전압감지센서가, 난방단수가 높을 경우의 인가전압을 감지하도록 구성되는 것이 좋다. 예를 들면, 온도조절도어 액츄에이터(22)의 인가전압이 3.05Ｖ이상일 경우를 감지하도록 구성되는 것이 좋다.Preferably, the door actuator applied voltage detecting sensor is configured to detect the applied voltage when the heating stage is high. For example, it is preferable to detect when the voltage applied to the temperature control door actuator 22 is 3.05 V or higher.

다시, 도 2를 참조하면, 본 발명의 공조장치는, 전기히터(10)를 "정상모드" 또는 "절전모드"로 선택할 수 있는 모드선택스위치(30)를 구비한다.Referring again to Fig. 2, the air conditioner of the present invention includes a mode selection switch 30 capable of selecting the electric heater 10 as a "normal mode" or a "power saving mode".

모드선택스위치(30)는, 운전석 전면의 인스트루패널(Instrument Panel)(도시하지 않음)에 설치되는 버튼식 스위치(Button Type Switch) 또는 로터리식 스위치(Rotary Type Switch)로 구성된다.The mode selection switch 30 is constituted by a button type switch or a rotary type switch installed in an instrument panel (not shown) on the front of the driver's seat.

이러한 모드선택스위치(30)는, 사용자가 조작함에 따라 전기히터(10)의 모드상태를 "정상모드" 또는 "절전모드"로 선택할 수 있게 한다.The mode selection switch 30 allows the mode of the electric heater 10 to be selected as the "normal mode" or the "power saving mode"

그리고 본 발명의 공조장치는, 배터리(7)의 충전량을 감지하는 배터리 충전량 감지수단(40)을 구비한다.The air conditioner of the present invention includes a battery charging amount sensing means (40) for sensing a charging amount of the battery (7).

배터리 충전량 감지수단(40)은, 배터리 충전량 감지센서로 구성되며, 배터리(7)의 충전량을 감지하여 후술하는 콘트롤러(50)에 입력시킨다.The battery charging amount detecting means 40 is constituted by a battery charging amount detecting sensor and detects the charged amount of the battery 7 and inputs the charged amount to the controller 50 to be described later.

다시, 도 2를 참조하면, 본 발명의 공조장치는, 콘트롤러(50)를 구비한다.Referring again to FIG. 2, the air conditioning apparatus of the present invention includes a controller 50.

콘트롤러(50)는, 마이크로 프로세서를 내장하고 있는 것으로, 난방 감지수단(20)으로부터 "난방모드신호"가 입력된 상태에서, 모드선택스위치(30)로부터 "절전모드"신호가 입력되면, 사용자(운전자)가 전기 소모량을 줄이고 싶어서 "절전모드"로 선택한 것으로 판단하여 상기 전기히터(10)를 오프(OFF)시킨다.When the "power save mode" signal is input from the mode selection switch 30 while the "heating mode signal" is input from the heating sensing means 20, the controller 50 incorporates a microprocessor. The driver is determined to select the "power save mode" because he / she wants to reduce the amount of electricity consumed, and turns off the electric heater 10 (OFF).

따라서, 전기히터(10)의 작동에 필요한 전기를 차단한다. 이로써, 전기히터(10)의 작동에 따른 전기소모를 방지한다. 그 결과, 전기소모로 인한 차량의 연비 저하현상을 방지할 수 있다.Thus, electricity required for the operation of the electric heater 10 is cut off. As a result, the electric consumption of the electric heater (10) is prevented. As a result, it is possible to prevent a phenomenon in which the fuel consumption of the vehicle is lowered due to electricity consumption.

반대로, 콘트롤러(50)는, 난방 감지수단(20)으로부터 "난방모드신호"가 입력된 상태에서, 모드선택스위치(30)로부터 "정상모드"신호가 입력되면, 전기히터(10)를 온(ON)시킨다. 따라서, 전기히터(10)로 하여금 차실내로 공급되는 공기를 가열할 수 있게 한다. 이로써, 차실내의 난방이 정상적으로 이루어질 수 있게 한다.Conversely, when the "normal mode" signal is input from the mode selection switch 30 while the "heating mode signal" is input from the heating sensing means 20, the controller 50 turns on the electric heater 10 ON). Thus, the electric heater 10 can heat the air supplied to the passenger compartment. Thus, heating of the interior of the vehicle can be normally performed.

한편, 콘트롤러(50)는, "정상모드"일 경우라도, 배터리 충전량 감지수단(40)에서 입력된 배터리(7)의 충전량이 미리 설정된 "기준충전량"이하이면, "절전모드"로 자동 전환시키도록 구성된다. 따라서, 전기히터(10)를 강제적으로 오프(OFF)시키도록 구성된다. On the other hand, even when the controller 50 is in the "normal mode ", when the charged amount of the battery 7 inputted from the battery charging amount detecting means 40 is equal to or smaller than the preset" reference charging amount & . Therefore, the electric heater 10 is forcibly turned off.

이렇게 구성한 이유는, 배터리(7)의 충전량이 "기준충전량"이하로 줄어들 경우, 차량의 상태가 절전모드인 것을 의미하므로, 전기히터(10)에 의한 전기 소비를 제한하기 위함이며, 이로써, 배터리(7)의 충전량이 과도하게 저하되지 않게 하기 위함이다. 그 결과, 배터리(7)의 충전량 저하로 인한 차량의 주행성능 저하현상을 미연에 방지한다. The reason for this configuration is to limit the electric consumption by the electric heater 10 because the state of the vehicle means that the vehicle is in the power saving mode when the charged amount of the battery 7 is reduced to the "reference charging amount & (7) is not excessively lowered. As a result, the running performance of the vehicle is prevented from deteriorating due to a decrease in the charged amount of the battery 7.

여기서, 콘트롤러(50)에 내장된 "기준충전량"은, 만충전(滿充電) 대비 80% 정도로 설정되는 것이 바람직하다. 이는, 배터리의 충전량이 만충전 대비 80%이하로 줄어들 경우, 차량의 주행성능이 저하될 우려가 있기 때문이다. Here, the "reference charge amount" built in the controller 50 is preferably set to about 80% of full charge. This is because, when the charged amount of the battery is reduced to 80% or less of the full charge, the running performance of the vehicle may be deteriorated.

한편, 콘트롤러(50)는, 배터리(7)의 충전량이 "기준충전량"을 초과할 경우, 차량의 상태가 정상모드이므로, "정상모드"로 복귀하면서 전기히터(10)를 재작동시킨다. 따라서, 차실내로 공급되는 공기의 온도가 다시 높아지면서 차실내를 다시 난방한다.On the other hand, when the charged amount of the battery 7 exceeds the "reference charged amount ", the controller 50 restarts the electric heater 10 while returning to the" normal mode " Therefore, the temperature of the air supplied to the inside of the car rises again, and the inside of the car is heated again.

다시, 도 2를 참조하면, 본 발명의 공조장치는, 차량의 주행속도를 감지하는 차속감지수단(60)을 더 구비한다.Referring again to FIG. 2, the air conditioner of the present invention further includes vehicle speed sensing means 60 for sensing the traveling speed of the vehicle.

차속감지수단(60)은, 차속센서로 구성되며, 차량의 주행속도를 감지하여 콘트롤러(50)에 입력시킨다.The vehicle speed sensing means 60 is constituted by a vehicle speed sensor and senses the traveling speed of the vehicle and inputs it to the controller 50. [

한편, 콘트롤러(50)는, "정상모드"시에 전기히터(10)를 온(ON)시키되, 차속감지수단(60)에서 입력된 차속이 미리 설정된 "기준차속"이하이면, 예를 들어, 10㎞/h 이면, "정상모드"에서 "절전모드"로 자동 전환시키도록 구성된다. 따라서, 전기히터(10)를 강제적으로 오프(OFF)시키도록 구성된다. On the other hand, the controller 50 turns on the electric heater 10 in the "normal mode ", and if the vehicle speed inputted from the vehicle speed sensing means 60 is less than the predetermined" reference vehicle speed & 10 km / h, it is configured to automatically switch from the "normal mode" to the "power saving mode ". Therefore, the electric heater 10 is forcibly turned off.

이렇게 구성한 이유는, 차량의 주행속도가 10㎞/h이하일 경우, 차량의 상태가 절전모드인 것을 의미하므로, 전기히터(10)에 의한 전기 소비를 제한하여 배터리(7)의 전기 소모량을 최소한으로 줄이기 위함이다.The reason for this configuration is that when the traveling speed of the vehicle is 10 km / h or less, the state of the vehicle means that the vehicle is in the power saving mode, so that the electric consumption by the electric heater 10 is limited, To reduce it.

한편, 콘트롤러(50)는, 차량의 주행속도가 "기준차속"을 초과할 경우, 차량의 상태가 정상모드이므로, "정상모드"로 복귀하면서 전기히터(10)를 재작동시킨다. 따라서, 차실내로 공급되는 공기의 온도가 다시 높아지면서 차실내를 난방한다.On the other hand, when the running speed of the vehicle exceeds the "reference vehicle speed ", the controller 50 restarts the electric heater 10 while returning to the" normal mode " Therefore, the temperature of the air supplied to the car interior is raised again, and the car interior is heated.

바람직하게는, 상기 콘트롤러(50)는, 차량의 주행속도가 "기준차속"을 초과할 경우에 전기히터(10)를 재작동시키되, 차량의 주행속도가 "기준차속"보다 높은 "제 2기준차속", 예를 들면, 20㎞/h를 초과할 경우, "정상모드"로 복귀하면서 전기히터(10)를 재작동시키는 것이 좋다.Preferably, the controller 50 reactivates the electric heater 10 when the running speed of the vehicle exceeds the "reference vehicle speed ", while the running speed of the vehicle is higher than the" Vehicle speed ", for example, 20 km / h, it is preferable to restart the electric heater 10 while returning to the" normal mode ".

다시, 도 2를 참조하면, 본 발명의 공조장치는, 차량의 실내의 온도를 감지하는 실내온도 감지수단(70)을 더 구비한다.Referring again to FIG. 2, the air conditioner of the present invention further includes room temperature sensing means 70 for sensing the temperature of the interior of the vehicle.

실내온도 감지수단(70)은, 차실내에 설치되는 온도센서로 구성되며, 차량의 실내온도를 감지하여 콘트롤러(50)에 입력시킨다.The room temperature sensing means 70 is constituted by a temperature sensor installed in the interior of the vehicle, and detects the room temperature of the vehicle and inputs the sensed temperature to the controller 50.

한편, 콘트롤러(50)는, "절전모드"시에 전기히터(10)를 오프(OFF)시키되, 실내온도 감지수단(70)에서 입력된 차실내의 온도가 미리 설정된 "기준온도"이하로 떨어지면, "절전모드"에서 "정상모드"로 자동 전환시키도록 구성된다. 따라서, 전기히터(10)를 다시 온(ON)시키도록 구성된다.On the other hand, the controller 50 turns off the electric heater 10 at the time of the "power saving mode", and when the temperature of the vehicle interior inputted from the indoor temperature detecting means 70 falls below a predetermined "reference temperature" , And is automatically switched from the "power saving mode" to the "normal mode". Therefore, it is configured to turn on the electric heater 10 again.

이렇게 구성한 이유는, 차실내의 온도가 "기준온도"이하로 떨어지면, 차실내의 온도가 너무 낮아지기 때문이며, 이로써, 차량의 탑승객이 한기(寒氣)를 느낄 수 있기 때문이다. 따라서, 차량의 탑승객이 한기를 느끼기 전에 전기히터(10)를 다시 작동시킴으로써, 차실내를 항상 따뜻하게 유지시키기 위함이다.The reason for this configuration is that, when the temperature of the vehicle interior falls below the "reference temperature ", the temperature of the vehicle interior becomes too low, Therefore, the electric heater 10 is operated again before the passenger of the vehicle feels cold, so as to always keep the interior of the vehicle warm.

여기서, 콘트롤러(50)에 내장된 "기준온도"는, 온도조절스위치(도시하지 않음)에 의해 설정된 "세부 온도 설정값"보다 약 2℃낮은 온도로 설정되는 것이 바람직하다. 이는, 대부분의 탑승객들이, 차량의 실내온도가 정상적일 때보다 약 2℃정도 낮아졌을 때에 한기를 느끼기 때문이다.Here, it is preferable that the "reference temperature" built in the controller 50 is set to a temperature about 2 [deg.] C lower than the "detailed temperature set value" set by the temperature control switch (not shown). This is because most passengers feel a chill when the indoor temperature of the vehicle is lowered by about 2 ° C than when it is normal.

다음으로, 이와 같은 구성을 갖는 공조장치의 제어방법을 도 2와 도 5를 참고하여 설명한다.Next, a control method of the air conditioner having such a configuration will be described with reference to FIGS. 2 and 5. FIG.

먼저, 도 5를 참조하면, 차량의 시동이 온(ON)된 상태에서(S101), 블로어(16)가 온(ON)되었는지를 판단한다(S103).First, referring to FIG. 5, it is determined whether the blower 16 is turned on (S103) when the vehicle is turned on (S101).

판단 결과, 블로어(16)가 온 되었으면, 차실내가 난방모드 인가를 판단한다(S105).As a result of the determination, if the blower 16 is turned on, it is determined whether the vehicle interior is in the heating mode (S105).

판단 결과, 난방모드이면, 모드선택스위치(30)가 "절전모드"로 선택되었는지를 판단한다(S107).As a result of the determination, if the mode is the heating mode, it is determined whether the mode selection switch 30 is selected as the "power saving mode" (S107).

판단 결과, "절전모드"가 선택되었으면, "절전모드"로 진입한다(S109). 그러면, 전기히터(10)가 오프(OFF)되고, 연료전지 스택(5)과 전장품의 냉각수를 이용한 차실내 난방만 작동된다. 이로써, 배터리(7)의 전기소모가 방지된다. 그 결과, 차량의 연비가 향상된다.As a result of the determination, if the "power saving mode" is selected, the power saving mode is entered (S109). Then, the electric heater 10 is turned off, and only the vehicle interior heating using the cooling water of the fuel cell stack 5 and electrical equipment is operated. Thereby, the battery 7 is prevented from consuming electricity. As a result, the fuel economy of the vehicle is improved.

한편, "절전모드"가 선택되지 않았으면, 배터리(7)의 충전잔량이 만충전 대비 80% 이하인지를 판단한다(S111). On the other hand, if the "power saving mode" is not selected, it is determined whether the remaining charge of the battery 7 is 80% or less of the full charge (S111).

판단 결과, 배터리(7)의 충전잔량이 80% 이하이면, "절전모드"로 진입한다(S109). 따라서, 전기히터(10)가 오프(OFF)되면서 배터리(7)의 전기소모가 방지된다. As a result of the determination, if the remaining charge amount of the battery 7 is 80% or less, the power-saving mode is entered (S109). Thus, the electric heater 10 is turned off, and the electric power consumption of the battery 7 is prevented.

반대로, 배터리(7)의 충전잔량이 80%를 초과하면, 차량의 현재 주행속도가 "기준차속"이하인지를 다시 판단한다(S113).Conversely, if the remaining charge of the battery 7 exceeds 80%, it is again determined whether the current running speed of the vehicle is equal to or less than the "reference speed" (S113).

판단 결과, "기준차속"이하이면, "절전모드"로 진입한다(S109). 따라서, 전기히터(10)가 오프(OFF)되면서 배터리(7)의 전기소모가 방지된다. As a result of the determination, if it is equal to or less than the "reference vehicle speed ", the process enters the power saving mode (S109). Thus, the electric heater 10 is turned off, and the electric power consumption of the battery 7 is prevented.

반대로, "기준차속"을 초과하면, "정상모드"로 진입한다(S115). 따라서, 전기히터(10) 및, 연료전지 스택(5)과 전장품의 냉각수를 이용한 차실내 난방은 동시에 작동된다. 따라서, 차실내를 효율좋게 난방한다.Conversely, if the reference vehicle speed is exceeded, the vehicle enters the "normal mode" (S115). Therefore, the vehicle interior heating using the electric heater 10 and the cooling water of the fuel cell stack 5 and the electrical components is simultaneously operated. Therefore, the car interior is efficiently heated.

이와 같은 구성을 갖는 본 발명에 의하면, 차량의 상태가 절전모드일 경우에, 전기히터(10)를 강제로 오프(OFF)시킨 다음, 이를 보상하기 위해 연료전지 스택(30)과 전장품 냉각수를 난방의 열원으로 이용하는 구조이므로, 배터리(7)의 전기소모를 최소화시킬 수 있으면서 난방성능의 저하현상은 최소화시킬 수 있다.According to the present invention having such a configuration, when the vehicle is in the power saving mode, the electric heater 10 is forcibly turned off, and then the fuel cell stack 30 and the electric component cooling water are heated The electricity consumption of the battery 7 can be minimized, and the phenomenon of deterioration of the heating performance can be minimized.

또한, "절전모드"를 선택하여 전기히터(10)를 필요에 따라 오프시킬 수 있는 구조이므로, 전기히터(10)에 소모되는 전기를 필요에 따라 차단할 수 있다. 따라서, 전기히터(10)에 의해 소모되는 전기를 최대한 절감할 수 있다.In addition, since the electric heater 10 can be turned off as needed by selecting the "power saving mode", the electricity consumed by the electric heater 10 can be cut off if necessary. Therefore, electricity consumed by the electric heater 10 can be saved as much as possible.

또한, 전기히터(10)에 의해 소모되는 전기를 최대한 절감할 수 있으므로, 전기소모로 인한 차량의 연비 저하현상을 방지할 수 있다.In addition, since the electricity consumed by the electric heater 10 can be reduced to the utmost, it is possible to prevent the fuel consumption of the vehicle from being lowered due to the consumption of electric power.

또한, "절전모드"시에 차실내의 온도에 따라 전기히터(10)를 자동으로 온,오프시키는 구조이므로, 차실내의 난방성능을 저하시키지 않는 한도내에서 전기히터(10)의 작동을 최소화할 수 있다. 따라서, 전기 소모를 최소화할 수 있으며, 이로써, 차량의 연비를 향상시킬 수 있다.In addition, since the structure is such that the electric heater 10 is automatically turned on and off in accordance with the temperature of the vehicle room in the "power saving mode", the operation of the electric heater 10 is minimized within a range that does not lower the heating performance of the vehicle interior can do. Therefore, the electric consumption can be minimized, and the fuel consumption of the vehicle can be improved.

또한, 배터리(7)의 충전량에 따라 전기히터(10)를 자동으로 온,오프시키는 구조이므로, 배터리(7)의 충전량을 저감시키지 않고서도 차실내를 효과적으로 난방할 수 있다.Further, since the electric heater 10 is automatically turned on and off according to the charged amount of the battery 7, the interior of the vehicle can be efficiently heated without reducing the amount of charged battery 7.

또한, 배터리(7)의 충전량을 저감시키지 않고서도 차실내를 효과적으로 난방할 수 있으므로, 배터리(7)의 충전량 저감에 따른 차량의 연비 저하현상을 방지할 수 있다.In addition, the vehicle compartment can be effectively heated without reducing the amount of charge of the battery 7, so that the phenomenon in which the fuel consumption of the vehicle 7 is lowered due to the reduction of the charged amount of the battery 7 can be prevented.

이상에서는 본 발명의 바람직한 실시예를 예시적으로 설명하였으나, 본 발명의 범위는 이와 같은 특정 실시예에만 한정되는 것은 아니며, 특허청구범위에 기재된 범주내에서 적절하게 변경 가능한 것이다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
