Description

철도차량용 에어컨을 이용한 비상 환기장치{EMERGENCY VENTILATOR APPARATUS USING AIR CONDITIONER FOR RAILWAY CAR}Emergency ventilation system using air conditioner for railway vehicle {EMERGENCY VENTILATOR APPARATUS USING AIR CONDITIONER FOR RAILWAY CAR}

본 고안은 철도차량용 에어컨을 이용한 비상 환기장치에 관한 것으로, 더욱 상세하게는 철도차량의 운행중 외부전원이 차단되었을시에 에어컨을 통해 외부공기를 원활하게 유입시킬 수 있는 철도차량용 에어컨을 이용한 비상환기장치에 관한것이다.The present invention relates to an emergency ventilation apparatus using an air conditioner for a railway vehicle, and more particularly, an emergency ventilation apparatus using an air conditioner for a railway vehicle that can smoothly introduce external air through an air conditioner when an external power source is cut off during operation of the railway vehicle. It's about.

종래에는 도 1 에 도시된 바와 같이, 철도차량(1)의 상부측에 에어컨장치(10)가 설치되어 있어 차량의 실내를 냉방시킨다.In the related art, as shown in FIG. 1, the air conditioner 10 is installed on the upper side of the railway vehicle 1 to cool the interior of the vehicle.

이때에 에어컨장치(10)가 가동되어 온도가 낮아져 냉방되는 증발기의 차가워진 공기를 철도차량의 내부공기유입구(3)로 공급해주도록 증발기팬(4a),(4b)이 형성되어 있다.At this time, the air conditioner 10 is operated so that the evaporator fans 4a and 4b are formed to supply the cold air of the evaporator cooled by cooling down to the internal air inlet 3 of the railway vehicle.

상기 증발기팬(4a),(4b)은, 중앙에 구동모터(2)가 형성되어 있어 좌우측에 증발기팬(4a),(4b)이 일체로 결합되어 있는 구조로 되어 있다.The evaporator fans 4a and 4b have a drive motor 2 formed at the center thereof, and the evaporator fans 4a and 4b are integrally coupled to the left and right sides.

따라서, 종래의 에어컨의 모든 구동은 가선에서 흐르고 있는 전압으로, 예를 들면 AC22,000V/DC1,500V가 흐르는 것을 철도차량의 상부측에 외부의 전력을 받을 있도록 형성된 팬터그라프를 통해 유입되고, 유입된 전원은 철도차량의 보조전원장치를 통해 에어컨 전압에 맞게 AC 440V로 감압시켜준다.Therefore, all the driving of the conventional air conditioner is a voltage flowing in the household line, for example, AC22,000V / DC1,500V flows through a pantograph formed to receive external power to the upper side of the railroad car, and flows therein. The power is reduced to AC 440V according to the air conditioner voltage through the auxiliary power supply of the railway vehicle.

상기와 같이 에어컨에 전원을 공급해주는 보조전원장치가 고장시 또는 외부 가선에서 공급되는 전원이 차단되었을시에 내부로 유입되는 외부공기의 양이 적어지므로 철도차량의 내부 승객들에게 많은 불편함을 초래하게 된다.As described above, when the auxiliary power supply unit supplying the air conditioner fails or the power supplied from the external line is cut off, the amount of external air introduced into the air is reduced, which causes a lot of inconvenience to the passengers inside the railway vehicle. Done.

이러한 문제점을 해결하기 위해서 최근에는 고가의 제품인 인버터를 장착하여 사용하는 기술로 인버터를 이용해 밧데리의 DC 24V의 전압을 AC440으로 승압시켜 에어컨을 가동시킨다.In order to solve this problem, recently, an expensive inverter is used to install a technology that uses an inverter to boost the battery's DC 24V voltage to AC440 to operate the air conditioner.

이때의 인버터를 이용해 에어컨을 가공시킬시에는 철도차량에 장착되어 있는 밧데리의 사용시간을 단축하게 되어 가선에서의 전원 공급이 연장될시에 많은 문제점을 발생시키게 된다.When the air conditioner is processed using the inverter at this time, the use time of the battery mounted on the railway vehicle is shortened, which causes a lot of problems when the power supply is extended in the household.

또한, 인버터는 가격이 높을 뿐만 아니라, 중량도 많이 나가므로 일반사용시에도 효율성이 떨어지는 문제점이 있다.In addition, since the inverter is not only high in price, but also high in weight, there is a problem in that efficiency is lowered in general use.

따라서, 본 고안은 상기와 같은 종래의 문제점을 감안하여 창안된 것으로, 그 목적은 비상시에 가선의 전원 공급이 차단되었을시에 에어컨의 증발기팬만을 구동시킬 수 있도록 하여 외부의 공기를 내부로 원활하게 공급시켜 줄수 있는 철도차량용 에어컨을 이용한 비상 환기장치를 제공함에 있다.Therefore, the present invention was devised in view of the above-described conventional problems, and its purpose is to allow only the evaporator fan of the air conditioner to be driven when the power supply of the wire is cut off in an emergency so that external air can be smoothly flowed into the inside. To provide an emergency ventilation system using an air conditioner for railway vehicles that can be supplied.

상기와 같은 본 고안의 목적을 달성하기 위하여, 철도차량용 에어컨을 이용한 비상 환기장치는 에어컨의 좌우측 증발기 팬을 회전시키는 구동모터의 회전축에 일체로 회전되도록 형성된 기어부와, 상기 기어부에 맞물려 회전되도록 형성된 기어를 갖는 DC모터로 구성된다.In order to achieve the object of the present invention as described above, the emergency ventilation device using an air conditioner for a railway vehicle is a gear unit formed to rotate integrally with the rotation shaft of the drive motor for rotating the left and right evaporator fans of the air conditioner, and to be rotated in engagement with the gear unit; It consists of a DC motor with gears formed.

상기와 같이 구성된 본 고안의 철도차량용 에어컨을 이용한 비상 환기장치를 아래와 같이 설명한다.An emergency ventilation apparatus using the air conditioner for a railway vehicle of the present invention configured as described above will be described below.

본 고안은 에어컨에서 작동되는 증발기 팬(22a),(22b)을 회전시키기 위한 구동모터(20)가 형성되어 있다.The present invention is formed with a drive motor 20 for rotating the evaporator fans 22a, 22b operated in the air conditioner.

상기의 구동모터(20)는 좌우측에 회전축(28)이 동시에 회전되며, 상기의 회전에 의해 일체로 회전되도록 증발기팬(22a),(22b)이 결합된다.The drive motor 20 is rotated on the left and right at the same time the rotating shaft 28, the evaporator fan 22a, 22b is coupled to rotate integrally by the rotation.

증발기 팬(22a),(22b)을 회전시키는 구동모터(20)의 회전축(26)에는회전축(26)의 원주방향으로 일체로 회전되는 기어부(28)가 형성된다.The gear shaft 28 which is integrally rotated in the circumferential direction of the rotary shaft 26 is formed in the rotary shaft 26 of the drive motor 20 for rotating the evaporator fans 22a and 22b.

또한, 구동모터(20)의 회전축에 형성된 기어부(28)에 맞물려 회전되도록 기어부(29)를 갖는 DC모터(30)가 형성된다.In addition, a DC motor 30 having a gear portion 29 is formed to be engaged with the gear portion 28 formed on the rotation shaft of the drive motor 20.

상기의 구동모터(20)의 회전축에 형성된 기어부(28)는 위치에 따라 여러가지 형태로 사용할 수 있기는 하나 바람직하게는 베벨기어를 사용하는 것이 바람직하다.The gear unit 28 formed on the rotation shaft of the drive motor 20 can be used in various forms depending on the position, but preferably bevel gears are used.

상기와 같이 구성된 본 고안의 철도차량용 에어컨을 이용한 비상 환기장치를 첨부된 도면을 참조하여 아래와 같이 상세하게 설명한다.With reference to the accompanying drawings an emergency ventilation apparatus using an air conditioner for a railway vehicle of the present invention configured as described above will be described in detail as follows.

도 2 는 본 고안의 철도차량용 에어컨을 이용한 비상 환기장치를 나타낸 도면이고, 도 3 은 본 고안의 철도차량용 에어컨을 이용한 비상 환기장치의 작동상태를 나타내는 도면이다.2 is a view showing an emergency ventilation apparatus using an air conditioner for a railway vehicle of the present invention, Figure 3 is a view showing an operating state of the emergency ventilation apparatus using an air conditioner for a railway vehicle of the present invention.

본 고안의 철도차량용 에어컨을 이용한 비상 환기장치는, 철도차량에 장착되어 있는 충전용 밧데리(도시않음)를 바로 이용할 수 있도록 구동모터(20)외에 또다른 DC모터(30)가 장착된다.The emergency ventilation device using the air conditioner for a railway vehicle of the present invention is equipped with another DC motor 30 in addition to the driving motor 20 so that the charging battery (not shown) mounted on the railway vehicle can be used immediately.

따라서, 철도차량의 팬터그라프(도시않음)로 공급해주는 외부의 가선에서 인입되는 전원이 차단되면 증발기팬(22a),(22b)을 회전시키는 구동모터(20)가 정지되고, 일반적으로 철도차량을 제어하는 메인콘트롤부(도시않음) 등에서 자동적으로 DC모터(30)를 작동시킨다.Therefore, when the power input from the external wire supplying to the pantograph (not shown) of the railway vehicle is cut off, the driving motor 20 for rotating the evaporator fans 22a and 22b is stopped, and the railway vehicle is generally stopped. Main motor control unit (not shown), etc. to automatically operate the DC motor 30.

외부의 전원공급이 차단되면 구동모터(20)는 작동을 멈춤과 동시에 충전용 밧데리에 의해 작동되는 DC모터(30)를 구동시켜 구동모터(20)의 회전축(26)에 일체로 형성된 기어부(28)와 DC모터(30)에 형성된 기어부(29)가 서로 맞물려 회전되기 때문에 증발기팬(22a),(22b)은 다시 원활하게 회전된다.When the external power supply is cut off, the driving motor 20 stops the operation and at the same time drives the DC motor 30 operated by the charging battery to integrally form the gear unit (1) formed on the rotating shaft 26 of the driving motor 20 ( 28 and the gears 29 formed in the DC motor 30 are rotated in engagement with each other, the evaporator fans 22a, 22b rotate smoothly again.

따라서, 외부 가선에서 공급되는 전원이 차단되어 에어컨의 작동이 정지되어도 DC모터(30)에 의해 증발기팬(22a),(22b)이 회전되어 외부의 공기를 철도차량의 내부로 원활하게 공급시켜준다.Therefore, even if the power supplied from the external wire is cut off and the operation of the air conditioner is stopped, the evaporator fans 22a and 22b are rotated by the DC motor 30 to smoothly supply the outside air to the inside of the railway vehicle. .

즉, 에어컨 작동의 정지시 외부공기의 순환이 제대로 이루어지지 않음에 따라 철도차량 내부는 많은 사람들로 인해 산소량이 부족하게 된다.이를 위해 DC모터(30)에 의해 증발기팬(22a),(22b)를 자동적으로 회전시켜 철도차량의 내부공기와 외부공기의 환기를 이루게 한다.In other words, when the air conditioner is stopped, the circulation of external air is not properly performed, and therefore, the amount of oxygen is insufficient due to many people inside the railroad car. Rotate automatically to achieve ventilation of inside and outside air of railway vehicle.

상기 본 고안의 DC모터(30)의 특징은, 일반적으로 자동차에 사용되고 있는 시동전동기의 방식으로서 전원이 인가되면 회전축이 돌출되면서 회전되는 방식으로, DC모터(30)에 장착되어 있는 기어부(29)를 도 3 에 도시된 바와 같이, 작동시에만 밀쳐지게 하므로 증발기팬(22a),(22b)을 회전시키는 회전축(26)에 형성된 기어부(28)에 쉽게 맞물려 회전시킬 수 있다.The characteristic of the DC motor 30 of the present invention is a method of a starting motor that is generally used in automobiles, so that when the power is applied, the rotating shaft protrudes and rotates, and the gear unit 29 mounted on the DC motor 30 As shown in Figure 3, it is pushed only during operation can be easily engaged with the gear portion 28 formed on the rotary shaft 26 for rotating the evaporator fan (22a, 22b) can be rotated.

따라서, 증발기팬(22a),(22b)을 회전시키는 회전축(26)에 일체로 결합시켜 사용할 수도 있지만, 작은 간섭 등을 고려한다면 상기와 같이 작동시 DC모터(30)를 자동차용 시동전동기 등과 같이 회전축의 길이가 증감되게 작동되는 것을 사용하는 것이 좋다.Therefore, the evaporator fans 22a and 22b may be integrally coupled to the rotating shaft 26 for rotating, but considering the small interference, the DC motor 30 is operated as described above, such as an automobile starting motor. It is good to use the one that works with increasing length of rotation shaft.

본 고안의 DC모터(30)는 보조전원장치를 통해 정상적으로 전원을 공급받지 못할경우에는 철도차량의 자체에 장착되어 있는 충전밧데리를 바로 이용할 수 있기 때문에 충전밧데리부터 직접 직류 전류를 받아 바로 구동시킨다.상기 DC모터(30)에 의해 회전되는 증발기팬(22a),(22b)은 철도차량의 실내로 외부공기를 일정시간 동안 유입시키므로, 외부 가선의 전원 공급이 차단되어도 환기는 원활하게 이루어진다.When the DC motor 30 of the present invention does not normally receive power through the auxiliary power supply, it can directly use the charging battery mounted on the railway vehicle itself and directly drive the DC current directly from the charging battery. The evaporator fans 22a and 22b rotated by the DC motor 30 introduce external air into the interior of the railway vehicle for a predetermined time, so that ventilation is smoothly performed even when the power supply of the external wire is cut off.

따라서, 단전된 철도차량의 전원이 언제 재공급될지 모르는 상황에 처할 경우, 바로 DC모터(30)를 이용하여 에어컨의 전체를 작동시키는 경우보다 충전밧데리를 이용해 DC모터(30)만을 작동시키는 것이 바람직하다. 이는 에어컨의 작동시 소모되는 전류가 적은 DC모터(30)만을 작동시키므로 철도차량의 내부 온도가 상승은 해도 외부의 공기를 충분히 오랜시간 동안 공급시켜 줄수 있어 안정적이다.또한, 이로인해 철도차량의 충전용 밧데리의 사용시간을 증가시킬 수 있는 특징이 있다.Therefore, in a situation where the power of the disconnected railway vehicle may not be re-supplied, it is preferable to operate only the DC motor 30 using the charging battery rather than immediately operating the entire air conditioner using the DC motor 30. Do. Since only the DC motor 30 consumes less current when the air conditioner is operating, it is stable because it can supply the outside air for a long time even if the internal temperature of the railway vehicle rises. There is a characteristic that can increase the use time of the battery.

따라서, 본 고안의 철도차량용 에어컨을 이용한 비상 환기장치에 의해 비상시에 가선의 전원 공급이 차단되었을시에 에어컨의 증발기팬만을 구동시킬 수 있도록 하여 외부의 공기를 내부로 공급시켜 줄수 있어 승객들에게 쾌적한 환경을 제공할 수 있는 효과가 있다.Therefore, the emergency ventilation system using the air conditioner for railroad cars of the present invention can only drive the evaporator fan of the air conditioner when the power supply of the wire is cut off in an emergency, thereby supplying outside air to the passengers, which is pleasant to passengers. It has the effect of providing an environment.

그뿐만 아니라, 정전등으로 인한 단전 사태가 발생되는 비상 상황에 처할 경우, 산소부족 등으로 인해 승객들을 안전하게 보호할 수 있다.In addition, in case of an emergency situation in which a power failure occurs due to a power failure, the passengers may be safely protected due to lack of oxygen.

또한, 본 고안의 철도차량용 에어컨을 이용한 비상 환기장치에 의해 종래와 같이 고가의 인버터를 사용하지 않기때문에 제조 원가를 낮출 수 있다.In addition, the emergency ventilation device using the air conditioner for railway vehicles of the present invention can reduce the manufacturing cost because it does not use an expensive inverter as in the prior art.
