본 발명은 철도차량 등에 설치되는 열교환기의 냉방운전시 실외공기를 도입함에 있어서, 차량의 실내온도의 고저에 따라 실외공기를 도입하고 상기 도입된 실외공기를 실내공기와 혼합하면서 차량의 실내를 냉방시키도록 하며, 상기 혼합된 공기에 의하여 차량의 실내공기가 실외공기와의 혼합 및 순환이 이루어지도록 하고 상기 실내,외공기의 혼합에 의하여 차량의 실내 냉방을 쾌적하게 할 수 있도록 한 열차용 열교환기의 외기도입 제어장치에 관한 것이다.The present invention is to introduce the outdoor air during the cooling operation of the heat exchanger installed in a railway vehicle, the outdoor air according to the elevation of the indoor temperature of the vehicle and the indoor air of the vehicle is cooled while mixing the introduced outdoor air with the indoor air The heat exchanger for the train to allow the indoor air of the vehicle to mix and circulate with the outdoor air by the mixed air, and to make the indoor cooling of the vehicle comfortable by the mixing of the indoor and outdoor air. It relates to an external air control device.

종래 철도차량 등에 설치되는 열교환기는 압축기, 응축기, 건조기, 모세관, 증발기로 구성되어 있으며, 상기 압축기에서 압축된 냉매가 응축기에서 응축되어 고온,고압의 냉내를 상기 증발기로 보내고 이 증발기에서 증발작용을 하면서 열교환이 이루어지도록하여 냉방을 위한 냉기를 생성시키며 이 생성된 냉기를 차량의 실내와 연결된 덕트를 통하여 차량의 실내에 공급하면서 냉방을 시키도록 되어 있었다.The heat exchanger installed in a conventional railway vehicle is composed of a compressor, a condenser, a dryer, a capillary, and an evaporator. The refrigerant compressed in the compressor is condensed in the condenser to send the high temperature and high pressure cold to the evaporator, and evaporate in the evaporator. The heat exchange was performed to generate cold air for cooling and to cool the generated cold air while supplying the generated cold air to the interior of the vehicle through a duct connected to the interior of the vehicle.

또, 상기 철도차량과 같이 실내의 공간이 넓은 경우에는 상기 덕트의 냉기 토출구를 천정의 여러 위치에 여러개를 설치하도록 구성되어 있었고, 상기 토출구에는 회전기를 설치하여 상기 덕트를 통해 공급되는 냉기를 스윙방식으로 공급하도록 구성되어 있었다.In addition, when the indoor space is large, such as a railway vehicle, the air discharge ports of the ducts are configured to be installed at various locations on the ceiling, and the discharge holes are provided with a rotor to swing the cold air supplied through the ducts. It was configured to feed.

그러나, 상기와 같은 종래의 것은 상기 냉기를 단순히 차량의 실내측에 공급하도록 하면서 냉방작용을 하도록 되어 있었기 때문에 차량의 실내공기가 외기와 순환되지 못하게 되었고 이에 따라 상기 차량의 실내공기가 탁하게 되는 폐단이 있었으며, 상기 실내공기의 불순환에 따른 냉기의 축적으로 냉방효율이 극히 저하되는 폐단이 있었다.However, such a conventional method is designed to perform cooling while simply supplying the cold air to the indoor side of the vehicle, thereby preventing the indoor air of the vehicle from circulating with the outside air, and thus, the closed end at which the indoor air of the vehicle becomes cloudy. And, there was a closed end of the cooling efficiency is extremely reduced due to the accumulation of cold air caused by the indoor air circulation.

또, 상기의 점을 고려하여 상기 냉기의 토출구 일방에 외기가 도입될 수 있는통풍구를 형성하고 이 통풍구를 통하여 실외측의 공기가 차량의 실내로 도입되도록 한 것이 일부 있었으나, 상기 통풍구에 의한 실외공기 도입은 그 도입량의 제어가 이루어지지 못하기 때문에 상기 실외공기의 도입이 지나치게 많아 실내측 온도를 상승시키게 되는 일이 종종 발생하게 되고, 또 실외측의 외기 도입량이 적을 경우에는 상기 차량의 실내공기가 원활하게 순환되지 못하게 되어 실내공기의 정화를 도모할 수 없게 되는 점 등의 문제점이 있었다.In addition, in consideration of the above points, there was a part in which a vent opening through which air can be introduced into one of the outlets of the cold air is introduced, and the air on the outside side is introduced into the interior of the vehicle through the vent. Since introduction of the outdoor air is not controlled, the introduction of the outdoor air is excessively high and the indoor temperature is often increased, and when the outdoor air is introduced in a small amount, the indoor air of the vehicle is There was a problem such that it can not be smoothly circulated to prevent the purification of indoor air.

본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로 본 발명은 철도차량 등에 설치되는 열교환기의 냉방운전시 실외공기를 도입함에 있어서, 차량의 실내온도의 고저에 따라 실외공기를 도입하고 상기 도입된 실외공기를 실내공기와 혼합하면서 차량의 실내를 냉방시키도록 하며, 상기 혼합된 공기에 의하여 차량의 실내공기가 실외공기와의 혼합 및 순환이 이루어지도록 하고 상기 실내,외공기의 혼합에 의하여 차량의 실내 냉방을 쾌적하게 할 수 있도록 한 열차용 열교환기의 외기도입 제어장치를 제공하려는 것인바, 이를 이하에서 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned conventional problems. The present invention introduces outdoor air during cooling operation of a heat exchanger installed in a railroad car, and introduces outdoor air according to the indoor temperature of the vehicle. The indoor air of the vehicle is cooled while mixing the introduced outdoor air with the indoor air, and the indoor air of the vehicle is mixed with the outdoor air and circulated by the mixed air, and the indoor and outdoor air are mixed with each other. It is intended to provide an external air intake control device for a train heat exchanger to make the indoor cooling of the vehicle comfortably, which will be described below in detail with reference to the accompanying drawings.

The outdoor air detection sensor 4 and the indoor air detection sensor 5 are connected to the central processing unit 2 to which the damper drive 3 is connected, and the central processing unit 2 is operated by the sensors.

이상과 같이 구성된 본 발명은 상기 압축기, 응축기, 증발기 등에 의한 냉방시스템(1)을 작동시키게 되면, 도 2에서와 같이 상기 압축기에서 압축된 냉매가 응축기에서 응축되고 이 응축된 냉매를 상기 증발기에서 증발시켜 냉방운전을 하게 되며 상기 중앙처리장치(2)에 입력되어 설정된 온도가 상기 실내공기 검출센서(5)에서 검지한 실내온도와 비교하여 그 차이가 1℃이하일 경우에는 실내측의 냉방운전을 계속 진행하게 되고, 상기 실외공기 검출센서(4)와 실내공기 검출센서(5)에서 각각 검지된 실외 및 실내측 온도의 차이가 4℃ 이상일 경우에는 외기의 도입량을 적게하고 냉기의 공급을 많게하여 실내의 냉방을 도모하게 된다.According to the present invention configured as described above, when the cooling system 1 is operated by the compressor, the condenser, the evaporator, and the like, as shown in FIG. 2, the refrigerant compressed in the compressor is condensed in the condenser, and the condensed refrigerant is evaporated in the evaporator. Cooling operation is performed. If the set temperature input to the central processing unit (2) is less than 1 ° C compared to the room temperature detected by the indoor air detection sensor (5), the cooling operation of the indoor side is continued. When the difference between the outdoor and indoor temperature detected by the outdoor air detection sensor 4 and the indoor air detection sensor 5 is 4 ° C. or more, the amount of introduced air is reduced and the supply of cold air is increased so that the indoor air is increased. It is planned to cool down.

또, 상기 실외공기를 도입하는 통풍구의 댐퍼를 상기 실외공기 도입용 모터(6)와 증발기 팬(7)의 선택적인 작동에 따라 댐퍼드라이브(3)가 작동시키게 되면, 상기 검출된 온도의 차이에 의하여 외기의 도입량을 조절할 수 있게 되며 상기 실내온도와 설정온도의 차이가 1℃이상일 경우에는 상기 댐퍼를 작동시켜 외기를 도입할 수 있도록 하고 1℃이하일 경우에는 외기의 도입을 차단하게 된다.In addition, when the damper drive 3 is operated according to the selective operation of the outdoor air introduction motor 6 and the evaporator fan 7, the damper of the ventilation opening for introducing the outdoor air is applied to the difference in the detected temperature. It is possible to adjust the introduction amount of the outside air, and when the difference between the room temperature and the set temperature is 1 ℃ or more to operate the damper to introduce the outside air, when the temperature is less than 1 ℃ to block the introduction of the outside air.

따라서, 상기 실외의 공기온도가 실내 공기온도보다 4℃ 이상일 경우에는 상기 실외공기 도입용 모터(6)가 작동하여 도입풍량을 적게 하고 상기 온도가 2℃이상일경우에는 외기의 도입량을 중간정도로 하며, 상기 온도차가 2℃이하일 경우에는 상기 외기의 도입량을 많게하여 실내의 공기와 혼합되도록 하면서 실내측의 공기를 정화시키도록 한 것이다.Therefore, when the outdoor air temperature is 4 ° C. or higher than the indoor air temperature, the outdoor air introduction motor 6 operates to reduce the amount of introduced air, and when the temperature is 2 ° C. or higher, the amount of outdoor air is made medium. When the temperature difference is 2 ° C. or less, the amount of introduced outside air is increased so as to be mixed with indoor air while purifying the indoor air.

이상과 같은 본 발명은 상기와 같이 철도차량에 설치되어 차량의 실내 냉방을 도모하도록 한 것에 있어서, 상기 차량의 실내 공기와 실외측 공기를 이들의 온도차에 따라 실외측 공기를 적절하게 도입하여 혼합되도록 하고 상기 혼합된 공기를 이용하여 차량의 실내 냉방을 도모하면서 실내측 공기의 환기를 도모할 수 있게 되며, 상기 차량의 실내,외 온도변화에 따라 신속하게 외기의 도입량을 조절하도록 하므로써 차량의 실내공기를 쾌적하게 할 수 있고, 상기 열교환되어 혼합된 공기를 이용하게 되므로 상기 열교환기의 냉방 및 환기효율을 크게 향상시킬 수 있는 점 등의 특징을 지닌 것이다.The present invention as described above is installed in the railroad car as described above to achieve the indoor cooling of the vehicle, so that the indoor air and the outdoor side air of the vehicle is appropriately introduced by mixing the outdoor side air according to their temperature difference. And by using the mixed air to achieve the indoor cooling of the vehicle and to promote the ventilation of the indoor side, by adjusting the amount of outdoor air in accordance with the indoor and outdoor temperature changes of the vehicle by the indoor air of the vehicle It can be made comfortable, and because the use of the heat exchanged and mixed air has a feature such as to greatly improve the cooling and ventilation efficiency of the heat exchanger.
