Description
본 발명은 철도차량 등에 설치되는 에어컨에 있어서, 이 에어컨에서 발생되는 다량의 응축수를 응축기에 분사시켜 응축잠열을 외부로 배출시키고 상기 응축기에서의 고열을 냉각시켜 상기 에어컨의 냉방효율을 향상시킬 수 있도록 한 열차용 에어컨의 냉방시스템에 관한 것이다.The present invention provides an air conditioner installed in a railway vehicle, such that a large amount of condensate generated from the air conditioner is injected into a condenser to discharge the latent heat of condensation to the outside and to cool the high temperature in the condenser to improve the cooling efficiency of the air conditioner. A cooling system for an air conditioner for a train.
종래 철도차량 등에 설치되는 에어컨은 도 1에서와 같이 압축기(1), 응축기(2), 건조기(3),모세관(4),증발기(5)로 구성되어 있고, 또 액체분리기(6), 고,저압 스위치(7), 응축기 모터(8), 블로어(9), 드레인팬(10)으로 구성되어 있었다.Conventionally, an air conditioner installed in a railway vehicle is composed of a compressor (1), a condenser (2), a dryer (3), a capillary tube (4), and an evaporator (5), as shown in FIG. And the low pressure switch 7, the condenser motor 8, the blower 9, and the drain pan 10.
또, 상기 에어컨은 증발기 출구의 저온,저압의 기체냉매가 압축기를 거치면서 고온,고압의 기체냉매로 상태변화를 하고, 이 냉매는 압축기 출구와 응축기 입구를 연결하는 냉매관을 따라 응축기로 이송, 통과하면서 고온,고압의 액체냉매로 응축되며, 상기 응축된 냉매는 응축기 및 응축기 모터에 설치된 송풍팬에 의하여 강제적으로 상기 응축기의 응축잠열을 외부로 배출시키게 된다.In addition, the air conditioner changes the state of the low-temperature, low-pressure gas refrigerant at the evaporator outlet to the high-temperature, high-pressure gas refrigerant through the compressor, the refrigerant is transferred to the condenser along the refrigerant pipe connecting the compressor outlet and the condenser inlet, Condensed into a liquid refrigerant of high temperature and high pressure while passing through, and the condensed refrigerant is forcibly discharged the latent heat of condensation of the condenser by a blower fan installed in the condenser and the condenser motor.
상기 응축기에서 응축된 냉매는 건조기를 모세관으로 이송되고 이 모세관에서 증발이 가능한 상태의 저온,저압 냉매로 변환시키며 이를 증발기로 보내고 이 증발기에서는 상기 냉매를 저온,저압의 기체냉매로 증발시키면서 공기와 열을 흡수하게 되며 이 증발작용으로 냉기를 생성시켜 이를 열차의 실내로 공급하게 된다.The refrigerant condensed in the condenser transfers the dryer to a capillary tube and converts it into a low-temperature, low-pressure refrigerant in a state capable of evaporating from the capillary tube, and sends it to an evaporator, where the evaporator evaporates the refrigerant into a low-temperature, low-pressure gas refrigerant while air and heat This evaporation produces cold air and supplies it to the train's interior.
상기와 같이 작용함에 있어서, 종래에는 상기 증발기의 표면에 응축수가 발생하게 되고 이 발생된 응축수를 드레인팬에 모아 일정량 이상이 되면, 이를 외부로 자연배출하도록 하고 있었다.In the operation as described above, conventionally condensed water is generated on the surface of the evaporator and when the generated condensate is collected in a drain pan or more than a predetermined amount, it was to be naturally discharged to the outside.
그러나, 상기와 같은 종래의 상기 모아진 응축수를 그대로 자연배수시키기 때문에 상기 배수되는 응축수를 재활용하지 못하게 되는 폐단이 있었다.However, since the conventional condensed water collected as described above is naturally drained, there is a closed end that the condensed water is not recycled.
본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로 본 발명은 철도차량 등에 설치되는 에어컨에 있어서, 이 에어컨에서 발생되는 다량의 응축수를 수집하고 이 수집된 응축수를 분사수단으로 응축기에 분사시켜 응축잠열을 외부로 배출시키며 상기 응축기에서의 고열을 냉각시켜 응축기의 응축효율을 향상시킴과 동시에 상기 에어컨의 냉방효율을 향상시킬 수 있도록 한 열차용 에어컨의 냉방시스템을 제공하려는 것인바, 이를 이하에서 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-described conventional problems, the present invention is an air conditioner installed in a railway vehicle, etc., collecting a large amount of condensate generated from the air conditioner and spraying the collected condensate to the condenser by the injection means By discharging the latent heat of condensation to the outside and cooling the high heat in the condenser to improve the condensation efficiency of the condenser and at the same time to provide a cooling system of a train air conditioner to improve the cooling efficiency of the air conditioner, which will be described below Based on the accompanying drawings in detail as follows.
