The purpose is to make it possible.

특히, 공조장치의 난방장치는 엔진에서 나오는 고온의 냉각수가 히터코어를 지나 다시 엔진으로 환원되는 과정에서 히터코어를 통과하는 공기를 히터코어 내부를 흐르는 고온의 냉각수와 열교환시켜 공기의 온도를 상승시키고, 이 고온의 공기를 차량 실내에 공급함으로써 실내를 난방하는 것이다.In particular, the heating device of the air conditioning unit heats the air passing through the heater core with the high temperature cooling water flowing inside the heater core while the high temperature cooling water from the engine passes through the heater core and back to the engine to increase the temperature of the air. In this case, the room is heated by supplying the high temperature air to the vehicle interior.

그런데, 하이브리드 또는 전기자동차의 경우에는 이 같은 엔진의 냉각수를 사용할 수 없기 때문에, 엔진의 냉각수를 이용한 히터코어 대신 고전압의 PTC 히터를 사용하고 있다.However, in the case of a hybrid or electric vehicle, since the cooling water of such an engine cannot be used, a high voltage PTC heater is used instead of the heater core using the cooling water of the engine.

Calculate the temperature of the, and adjust the opening degree of the temp door 19 accordingly to supply the air of the optimum temperature to the vehicle interior.

그러나, 종래의 차량용 공조장치(10)는 난방 모드 후 난방 모드가 정지되더라도 고전압 PTC 히터(18)의 특성상 PTC 히터(18)의 온도가 쉽게 내려가지 않는다.However, in the vehicle air conditioner 10 of the related art, even if the heating mode is stopped after the heating mode, the temperature of the PTC heater 18 is not easily lowered due to the characteristics of the high voltage PTC heater 18.

이때, 차량용 공조장치(10)를 작동시키게 되면, 템프도어(19)는 난방 모드의 상태(PTC 히터를 바이패스하는 유로를 폐쇄한 상태)로 맵핑되어 있고, 아직 PTC 히터(18)가 고온을 유지하고 있기 때문에, 차량 실내로 온기가 토출되어 탑승자가 불쾌감을 느끼는 문제점이 있었다.At this time, when the vehicle air conditioner 10 is operated, the temp door 19 is mapped to the state of the heating mode (the state which closed the flow path which bypasses a PTC heater), and the PTC heater 18 is still high temperature. Because of the maintenance, there is a problem that the warmth is discharged to the interior of the vehicle and the passenger feels uncomfortable.

이하 첨부된 도면을 참조하여 본 발명을 상세하게 설명한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings.

첨부된 도면은 본 발명의 예시적인 형태를 도시한 것으로, 이는 본 발명을 보다 상세히 설명하기 위해 제공되는 것일 뿐, 이에 의해 본 발명의 기술적인 범위가 한정되는 것은 아니다.BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

먼저, 본 발명에 따른 차량용 공조장치의 제어방법이 적용되는 차량용 공조장치의 내부 구성에 대해 간단히 설명하기로 한다.First, the internal configuration of the vehicle air conditioner to which the control method of the vehicle air conditioner according to the present invention is applied will be briefly described.

도 1에 도시된 바와 같이, 공조케이스(11)의 내부 유로인 송풍 유로 중 상류 측에 증발기(17)가 설치되어 있고, 하류 측 쪽에 PTC 히터(18)가 설치되어 있다.As shown in FIG. 1, the evaporator 17 is provided in the upstream side of the ventilation flow path which is an internal flow path of the air conditioning case 11, and the PTC heater 18 is provided in the downstream side.

부언하면, 증발기(17)와 PTC 히터(18)는 공조케이스(11)의 송풍 유로 상에 일정간격 이격되게 설치되어 있다.In other words, the evaporator 17 and the PTC heater 18 are provided at regular intervals on the air flow passage of the air conditioning case 11.

여기서, 본 발명의 경우에는 PTC 히터(18) 만이 설치되어 있는 것으로 설명하지만, 차량의 종류에 따라 PTC 히터(18)와 엔진의 냉각수에 의해 열을 공급하는 히터코어가 동시에 설치될 수도 있다.Here, in the case of the present invention, only the PTC heater 18 is described, but according to the type of vehicle, the heater core for supplying heat by the cooling water of the engine and the PTC heater 18 may be provided at the same time.

그리고, 공조케이스(11)의 공기 유입구(12) 측에는 송풍 유로로 공기를 송풍하는 블로어(미도시)가 설치되어 있다.And the blower (not shown) which blows air to a ventilation flow path is provided in the air inflow port 12 side of the air conditioning case 11. As shown in FIG.

이 블로어의 구동에 의하여 공조케이스(11)의 내부로 공기가 송풍되며, 이렇게 송풍된 공기는 증발기(17) 또는 PTC 히터(18)를 거치면서 공기가 열교환되어 냉기 또는 온기가 차량 실내로 공급된다.Air is blown into the air-conditioning case 11 by driving the blower. The blown air is heat-exchanged while passing through the evaporator 17 or the PTC heater 18 so that cold or warm air is supplied to the vehicle interior. .

여기서, 공조케이스(11)의 내부에는 PTC 히터(18)를 통과하는 유로(20)와, PTC 히터(18)를 바이패스하는 유로(21)가 형성되고, 증발기(17)와 PTC 히터(18)의 사이에는 상기 유로(20, 21)의 개도를 조절하는 템프도어(19)가 설치되어 있다.Here, the air passage 20 passing through the PTC heater 18 and the flow passage 21 bypassing the PTC heater 18 are formed inside the air conditioning case 11, and the evaporator 17 and the PTC heater 18 are formed. ), A temporal door 19 for adjusting the opening degree of the flow paths 20 and 21 is provided.

따라서, 템프도어(19)가 PTC 히터(18)를 통과하는 유로(20)를 폐쇄하고 있을 경우에는 증발기(17)를 통과한 공기가 PTC 히터(18)를 거치지 않고 PTC 히터(18)를 바이패스하는 유로(21)를 통과하게 된다.Thus, when the temporal door 19 is closing the flow path 20 passing through the PTC heater 18, the air passing through the evaporator 17 bypasses the PTC heater 18 without passing through the PTC heater 18. It passes through the flow path 21 which passes.

반대로, 템프도어(19)가 PTC 히터(18)를 바이패스하는 유로(21)를 폐쇄하고 있을 경우에는 증발기(17)를 통과한 공기가 모두 PTC 히터(18)를 통과하게 된다.On the contrary, when the temporal door 19 is closing the flow path 21 which bypasses the PTC heater 18, all the air which passed the evaporator 17 passes through the PTC heater 18. As shown in FIG.

이때, 템프도어(19)가 상기한 상태가 아닌 대략 중간쯤에 위치한 경우에는 증발기(17)를 통과한 공기 중 일부는 PTC 히터(18)를 통과하는 유로(20)를 통과하고, 나머지는 PTC 히터(18)를 바이패스하는 유로(21)를 통과하게 되어 온기와 냉기를 혼합하여 적절한 온도의 공기를 차량 실내로 공급한다.At this time, when the temporal door 19 is located at about the middle, not in the above state, some of the air passing through the evaporator 17 passes through the flow path 20 passing through the PTC heater 18, and the rest is PTC. The heater 18 passes through the flow path 21 bypassing the heater 18 to mix the warm air and cold air to supply air of a suitable temperature to the vehicle interior.

즉, 템프도어(19)의 위치에 따라 차량 실내로 공급되는 공기의 온도가 결정된다.That is, the temperature of the air supplied to the vehicle interior is determined according to the position of the temp door 19.

상기와 같은 템프도어(19)는 도 2에 도시된 차량용 공조장치의 컨트롤러(100)에 의해 위치가 결정된다.The temp door 19 as described above is determined by the controller 100 of the vehicle air conditioner illustrated in FIG. 2.

컨트롤러(100)는 외기온도 센서(110), 내기온도 센서(120), 일사센서(130), 토출온도 센서(140) 및 PTC 히터 센서(150)의 감지결과를 인가받아 템프도어(19)의 위치를 결정하여 차량 실내로 최적 온도의 공기가 공급되도록 한다.The controller 100 receives the sensing result of the outside temperature sensor 110, the inside temperature sensor 120, the solar radiation sensor 130, the discharge temperature sensor 140, and the PTC heater sensor 150 to receive the temperature of the temp door 19. The position is determined so that the air of optimum temperature is supplied to the vehicle interior.

한편, 벤트(13, 14, 15) 및 벤트도어(16a, 16b, 16c)는 증발기(17) 또는 PTC 히터(18)에 의해 발생된 냉기 또는 온기를 차량 실내로 공급하는 부분이다.
On the other hand, the vents 13, 14, 15 and the vent doors 16a, 16b, 16c are parts for supplying cold air or warm air generated by the evaporator 17 or the PTC heater 18 to the vehicle interior.

이하에서는 본 발명에 따른 차량용 공조장치의 제어방법을 도 3을 참조하여 상세하게 설명한다.Hereinafter, a control method of a vehicle air conditioner according to the present invention will be described in detail with reference to FIG. 3.

먼저, 컨트롤러(100)가 외기온도 센서(110), 내기온도 센서(120) 및 일사 센서(130)에 의해 검출된 정보를 수신하는 단계를 수행한다.(S1)First, the controller 100 performs a step of receiving information detected by the outside temperature sensor 110, the inside temperature sensor 120, and the solar radiation sensor 130 (S1).

그 후, 컨트롤러(100)는 수신된 검출 정보에 근거하여 차량 실내로 토출될 목표 토출공기온도를 연산하는 단계를 수행한다.(S2)Thereafter, the controller 100 calculates a target discharge air temperature to be discharged into the vehicle interior based on the received detection information.

상기 단계(S2) 후, 차량용 공조장치의 블로어가 작동되는지를 판단하는 단계를 수행한다.(S3)After the step S2, it is determined whether the blower of the vehicle air conditioner is operated.

Perform the step (S4).

그 후, PTC 히터(18)의 온도가 상기 단계(S2)의 목표 토출공기온도를 초과하는 경우, 컨트롤러(100)는 템프도어(19)를 조절하여 PTC 히터(18)를 통과하는 유로(20)를 폐쇄하도록 템프도어(19)를 위치시킨다.(S5)After that, when the temperature of the PTC heater 18 exceeds the target discharge air temperature of the step S2, the controller 100 adjusts the temporal door 19 to pass through the PTC heater 18. ) Position the temp door 19 to close (S5).

이때, PTC 히터(18)의 온도가 상기 단계(S2)의 목표 토출공기온도 이하일 경우에는 템프도어(19)의 현재 위치를 유지하도록 컨트롤러(100)가 템프도어(19)를 제어한다.(S8)At this time, when the temperature of the PTC heater 18 is equal to or lower than the target discharge air temperature of the step S2, the controller 100 controls the temporal door 19 to maintain the current position of the temporal door 19. (S8 )

한편, 상기 단계(S5) 후, 현재 차 실내로 토출되는 공기의 온도와 상기 단계(S2)의 목표 토출공기온도가 동일한지를 판단하는 단계를 수행한다.(S6)On the other hand, after the step (S5), it is determined whether the current temperature of the air discharged to the vehicle interior and the target discharge air temperature of the step (S2) is the same (S6).

상기 단계(S6)의 판단 결과, 차 실내 토출공기온도와 상기 단계(S2)의 목표 토출공기온도가 동일한 경우에는 템프도어(19)의 현재 위치를 유지하도록 컨트롤러(100)가 템프도어(19)를 제어한다.(S8)As a result of the determination in step S6, when the next indoor discharge air temperature and the target discharge air temperature in step S2 are the same, the controller 100 maintains the current position of the temp door 19 so that the temper door 19 is maintained. Control (S8)

여기서, 템프도어(19)는 PI제어(비례적분제어)에 의해 제어되어 실제 차 실내 토출공기온도와 목표 토출공기온도가 동일해지도록 한다.Here, the temp door 19 is controlled by PI control (proportional integral control) so that the actual indoor discharge air temperature and the target discharge air temperature are the same.

PI제어는 제어 변수와 기준 입력 사이의 오차에 근거하여 계통의 출력이 기준 전압을 유지하도록 하는 피드백 제어의 일종으로, 오차 신호를 적분하여 제어 신호를 만드는 적분 제어를 비례 제어에 병렬로 연결해 사용하는 것이다.PI control is a kind of feedback control that allows the output of the system to maintain the reference voltage based on the error between the control variable and the reference input.Integral control, which integrates the error signal to make the control signal, is connected in parallel to the proportional control. will be.

상기와 같은 본 발명에 따른 차량용 공조장치의 제어방법은 PTC 히터(18)의 온도가 차량 실내로 공급될 공기의 최적 온도보다 높을 경우, PTC 히터(18)를 통과하는 유로(20)를 템프도어(19)에 의해 폐쇄함으로써, 공기가 PTC 히터(18)를 통과하지 않게 되므로 토출될 최적 온도보다 높은 온도의 공기가 차량 실내로 토출되지 않아 탑승자에게 불쾌감을 주는 문제점을 해결할 수 있게 된다.
In the control method of the vehicle air conditioner according to the present invention as described above, when the temperature of the PTC heater 18 is higher than the optimum temperature of the air to be supplied to the vehicle interior, the flow path 20 through the PTC heater 18, the tempor door By closing by (19), since the air does not pass through the PTC heater 18, air of a temperature higher than the optimum temperature to be discharged is not discharged to the vehicle interior, thereby solving the problem of discomfort to the occupant.
