By using this, in winter, when the car's room temperature rises, it cools down when seating, and in summer, it prevents eczema by sitting for a long time, thereby improving the riding comfort.
이러한 냉난방 통풍 시스템에는 열전소자(Thermoelectric Device, TED)가 형성되어 상기 열전소자에 전류를 인가하면 냉각 및 가열되고, 냉각 및 가열된 열전소자에 공기를 통과시켜 냉방 및 난방이 가동된다.A thermoelectric device (TED) is formed in the air-conditioning ventilation system. When a current is applied to the thermoelectric device, cooling and heating are performed, and cooling and heating are performed by passing air through the cooled and heated thermoelectric device.
여기서 냉난방 통풍 시스템의 열전소자를 이용하여 냉방 및 난방을 가동할 경우 자동차 실내 습도에 따라서 열전소자에 이슬이 맺히는 현상인 응결수가 발생된다. 발생된 응결수를 방치할 경우 열전소자에 성능을 저해하고 오동작을 일으킬 수 있다.In this case, when cooling and heating are performed using a thermoelectric element of a cooling and heating ventilation system, condensation water, which is a phenomenon in which dew forms on the thermoelectric element according to the indoor humidity of a vehicle, is generated.

난방단계(S31)에서 난방이 가동되면 역전류가 설정시간 동안 인가되었는지 확인한다(S33). 역전류 인가 시간이 설정시간을 경과하지 않으면 계속해서 역전류를 인가한다. 본 실시예에서는 역전류를 인가하는 설정시간을 5초로 설정하여 역전류를 인가한다.When the heating is operated in the heating step (S31) it is checked whether the reverse current is applied for a set time (S33). If the reverse current application time does not pass the set time, the reverse current is continuously applied. In this embodiment, the set time for applying reverse current is set to 5 seconds to apply reverse current.
상기 열전소자에 설정시간 동안 역전류를 인가하여 열이 발생함으로 응결수가 증발한다.Condensed water evaporates as heat is generated by applying reverse current to the thermoelectric element for a set time.
응결수 발생 판단단계(S30)에서 응결수가 발생하지 않으면, 상기 열전소자에 정전류를 연속적으로 인가하여 냉방을 유지한다(S40).If condensation water does not occur in the condensation water determination step (S30), cooling is continued by continuously applying a constant current to the thermoelectric element (S40).
도 2는 본 발명의 다른 실시예인 냉난방 통풍 시스템의 열전소자에 발생하는 응결수 제거 방법을 나타내는 순서도이다.2 is a flowchart illustrating a condensation water removal method occurring in a thermoelectric element of a cooling and heating ventilation system according to another embodiment of the present invention.
도 2를 참조하면, 상기 냉난방 통풍 시스템은 송풍 팬 온단계(S21)와, 송풍 팬 오프단계(S32)를 더 포함한다.2, the air-conditioning ventilation system further comprises a blowing fan on step (S21), and blowing fan off step (S32).
본 실시예에서는 도 1에서 설명한 내용은 생략하고 송풍 팬 온단계(S21)와, 송풍 팬 오프단계(S32)에 대해서 구체적으로 설명한다.In the present embodiment, the description of FIG. 1 will be omitted and the blower fan on step S21 and the blower fan off step S32 will be described in detail.
상기 냉난방 통풍 시스템이 냉방단계(S20)에서 상기 열전소자에 정전류를 인가하여 냉방이 가동되면 송풍 팬이 온으로 설정된다(S21). 상기 송풍 팬이 온으로 설정되면 냉각된 공기를 시트로 배출한다.When the cooling and heating ventilation system applies a constant current to the thermoelectric element in the cooling step (S20) and cooling is operated, the blowing fan is set to on (S21). When the blowing fan is set to on, the cooled air is discharged to the sheet.
또한, 난방단계(S31)에서 상기 열전소자에 역전류를 인가하여 난방이 가동되면 송풍 팬이 오프로 설정된다(S32). 상기 송풍 팬이 오프로 설정되면 가열된 공기가 시트로 배출되지 않아 상기 사용자는 가열된 공기와 접촉하지 않는다.In addition, when the heating is operated by applying a reverse current to the thermoelectric element in the heating step (S31), the blowing fan is set to off (S32). When the blower fan is set to off, heated air is not discharged to the seat so that the user does not come into contact with the heated air.
여기서 송풍 팬 온단계(S21)와, 송풍 팬 오프단계(S32)는 냉방단계(S20)에서 온, 난방단계(S31)에서 오프로 한정하지 않고, 응결수가 발생하는 조건, 습도, 온도 등의 상황에 따라서 선택적으로 설정할 수 있다.Here, the blowing fan on step S21 and the blowing fan off step S32 are not limited to being turned on in the cooling step S20 and off in the heating step S31, and conditions such as condensation water, humidity, and temperature are generated.

도 3을 참조하면, 상기 냉난방 통풍 시스템은 에어컨 구동을 확인한다(S50). 상기 에어컨이 구동되면 차량의 실내온도와 상대습도가 내려간다.Referring to Figure 3, the air-conditioning ventilation system checks the operation of the air conditioner (S50). When the air conditioner is driven, the indoor temperature and the relative humidity of the vehicle decrease.

상기 에어컨이 구동되면 열전소자에 정전류를 인가하여 연속적으로 운전한다(S60). 열전소자에 발생하는 응결수는 공기의 온도와 상대습도에 따라서 발생하는데, 에어컨의 구동으로 차량의 실내온도와 상대습도가 내려가 응결수가 발생하는 온도인 이슬점이 내려간다. 본 실시예에서는 냉방 가동 시 열전소자의 온도가 8~10℃로 냉각되는데 에어컨의 구동으로 차량의 실내온도와 상대습도가 내려가 [표 1]에 이슬점 산출표와 같이 공기의 온도가 20℃에서 상대습도가 45%로 내려가면 응결수가 발생하는 이슬점 온도가 7.0℃로 내려감으로 더 이상 응결수가 발생하지 않는다.When the air conditioner is driven to operate continuously by applying a constant current to the thermoelectric element (S60). The condensation water generated in the thermoelectric element is generated according to the temperature and relative humidity of the air, and the dew point, which is the temperature at which the condensation water is generated, decreases in the room temperature and the relative humidity of the vehicle by driving the air conditioner. In this embodiment, the temperature of the thermoelectric element is cooled to 8 ~ 10 ℃ during the cooling operation, the indoor temperature and relative humidity of the vehicle is lowered by the drive of the air conditioner as shown in the dew point calculation table in Table 1, the relative humidity at 20 ℃ When the temperature drops to 45%, the dew point temperature where the condensed water is generated is lowered to 7.0 ° C. and no more condensed water is generated.
도 4는 본 발명의 바림직한 일 실시예에 따른 시간에 따라 온도와 전류의 변화를 나타내는 도면이다.4 is a view showing a change in temperature and current with time according to a preferred embodiment of the present invention.
제 1 냉방단계(S1)에서는 상기 냉난방 통풍 시스템의 열전소자에 설정된 정전류를 인가하면, 상기 열전소자의 온도가 사용자가 설정한 냉방 온도로 하강 후 일정시간 유지되고, 상기 냉방 온도로 안정화된 이후 응결수가 발생하면 상기 열전소자의 온도가 하강한다.In the first cooling step (S1), when a constant current set to the thermoelectric element of the air-conditioning ventilation system is applied, the temperature of the thermoelectric element is lowered to the cooling temperature set by the user and maintained for a predetermined time, and then condensed after stabilizing to the cooling temperature. When water is generated, the temperature of the thermoelectric element drops.
제 1 냉방단계(S1)에서 응결수가 발생하면 난방단계(S5)에서 설정된 크기의 역전류를 설정된 시간동안 인가하여 열전소자에 발생된 응결수를 증발시킨다.When the condensation water is generated in the first cooling step S1, a reverse current having a magnitude set in the heating step S5 is applied for a predetermined time to evaporate the condensed water generated in the thermoelectric element.
상기 냉난방 통풍 시스템은 에어컨이 구동되지 않은 경우에는 제 1 냉방단계(S1)와 난방단계(S5)를 반복하여 가동된다.The air-conditioning ventilation system is operated by repeating the first cooling step S1 and the heating step S5 when the air conditioner is not driven.
상기 냉난방 통풍 시스템은 에어컨 구동 시 제 1 냉방단계(S1)와 난방단계(S5) 가동 후 제 2 냉방단계(S2)가 가동된다. 제 2 냉방단계(S2)는 설정된 정전류를 상기 열전소자에 인가하여 냉방을 가동하는데, 상기 열전소자의 온도는 사용자가 설정한 냉방 온도로 하강 후 제 1 냉방단계(S1)에서 유지되는 시간보다 일정시간 더 유지된 후 하강하게 된다. 여기서 상기 냉방 온도로 유지되는 시간의 차이는 상기 [표 1]의 이슬점 참조표와 같이 에어컨의 구동으로 공기의 온도와 상대습도가 내려가 이슬점 온도 또한 내려감으로 제 1 냉방단계(S1)보다 일정 시간 늦게 응결수가 발생하게 된다.The air-conditioning ventilation system operates the first air cooling step S1 and the heating step S5 when the air conditioner is driven, and then the second air cooling step S2 is operated. In the second cooling step S2, cooling is performed by applying a set constant current to the thermoelectric element, and the temperature of the thermoelectric element is lower than the time maintained in the first cooling step S1 after the temperature is lowered to the cooling temperature set by the user. After more time, it descends. Here, the difference in time maintained at the cooling temperature is a certain time later than the first cooling step (S1) as the dew point temperature is lowered as the air temperature and the relative humidity decrease as the air conditioner is driven, as shown in the dew point reference table of [Table 1]. Condensation water will occur.
제 2 냉방단계(S2)에서 응결수 발생을 판단하면 난방단계(S5)를 반복하여 응결수를 제거한 후 제 3 냉방단계(S3)가 구동된다.When it is determined that the condensed water is generated in the second cooling step S2, the condensed water is removed by repeating the heating step S5 and the third cooling step S3 is driven.
제 3 냉방단계(S3)에 공기의 온도와 상대습도는 제 2 냉방단계(S2)보다 더 내려가 상기 냉방 온도로 유지되는 시간이 제 2 냉방단계(S2)보다 더 길어진다. 상기 냉방 온도로 유지된 후 응결수가 발생하면 다시 온도가 하강하게 된다.The temperature and the relative humidity of the air in the third cooling step (S3) is lower than the second cooling step (S2) so that the time maintained at the cooling temperature is longer than the second cooling step (S2). When the condensed water is generated after being maintained at the cooling temperature is lowered again.
제 3 냉방단계(S3)에서 응결수 발생을 판단하면 난방단계(S5)가 다시 반복되며, 응결수가 제거되면 제 4 냉방단계(S4)가 가동된다.When it is determined that the condensed water is generated in the third cooling step S3, the heating step S5 is repeated again, and when the condensed water is removed, the fourth cooling step S4 is operated.
제 4 냉방단계(S4)는 정전류를 인가하여 상기 열전소자의 온도가 내려가 상기 냉방 온도를 유지한다. 제 4 냉방단계(S4)에서는 이슬점에 온도가 상기 열전소자의 온도보다 낮아지기 때문에 더이상 응결수가 발생하지 않는다.In the fourth cooling step S4, by applying a constant current, the temperature of the thermoelectric element is lowered to maintain the cooling temperature. In the fourth cooling step S4, the condensation water no longer occurs because the temperature at the dew point is lower than the temperature of the thermoelectric element.
따라서 제 4 냉방단계(S4)에 도달한 상기 냉난방 통풍 시스템은 더 이상 역전류 인가 없이 정전류를 연속 인가하여 냉방을 유지한다.Therefore, the cooling and heating ventilation system having reached the fourth cooling step S4 maintains cooling by applying a constant current continuously without applying reverse current any more.

The thermoelectric element maintains the cooling temperature for a predetermined time after applying the constant current having a predetermined size to reach the cooling temperature and lowering the cooling temperature.
상기 열전소자에 형성된 온도 센서를 이용하여 열전소자의 온도가 상기 냉방 온도로 안정화된 이후 상기 냉방 온도 이하로 하강하는지 확인한다(S35). 상기 냉난방 통풍 시스템이 냉방을 가동하면 공기 내의 수분이 응결되어 열전소자에 이슬이 맺히는 현상인 응결수가 발생하고, 냉각된 열전소자를 통과하는 공기가 응결수로 인하여 제대로 통과하지 못하게 됨으로 온도가 하강하게 된다.After the temperature of the thermoelectric element is stabilized to the cooling temperature by using the temperature sensor formed in the thermoelectric element, it is checked whether the temperature falls below the cooling temperature (S35). When the cooling and heating ventilation system operates cooling, condensation water, which is a phenomenon in which dew condenses on the thermoelectric element, is generated, and air passing through the cooled thermoelectric element does not pass properly due to the condensation water so that the temperature decreases. do.
온도 하강 확인단계(S35)에서 상기 열전소자의 온도가 하강하면 열전소자에 응결수가 발생한 것으로 판단한다(S36).When the temperature of the thermoelectric element decreases in the temperature drop checking step (S35), it is determined that condensation water has occurred in the thermoelectric element (S36).
