Abstract

A waste heat recovery type clean ventilation system for a vehicle is provided to reduce energy consumption by smoothly ventilating a vehicle, and improve the quality of inside air of the vehicle by promptly discharging polluted air of the vehicle and supplying clean external air to the inside of the vehicle. If a user sets up a ventilation mode, an air supply fan and an exhaust fan are operated at the same time. An air supply bypass damper(30b) formed at an external air supply duct is closed while an air supply damper(30a) is opened, to filter external air polluted through an external suction path by an external air filter primarily. The polluted external air is processed while recovering sensible heat and latent heat of indoor air exhausted through a heat exchanger. An anion generator installed at an air supply port generates anion to supply clean air to the inside of a vehicle.

본 발명은 차량 실내공기 폐열회수형 청정 환기장치에 관한 것으로서 더욱 상세하게는 냉난방 가동시 또는 환기 모드시 급기와 배기를 동시에 행하여 항상 적정한 풍량의 신선외기 공급과 차량 실내에서 발생되어 오염된 차량 실내공기의 신속한 배출과 함께 폐열을 고효율로 회수함으로서 에너지를 절감하면서 쾌적한 차량실내 환경을 항상 안정적으로 유지할 수 있도록 한 환기장치에 관한 것이다.The present invention relates to a waste heat recovery type clean ventilator for vehicle indoor air, and more particularly, to supply air and exhaust air at an appropriate amount of air at a time of cooling and heating operation or at the same time in a ventilation mode, and to contaminate vehicle indoor air that is generated and contaminated inside the vehicle. The present invention relates to a ventilator that enables to maintain a pleasant indoor environment at all times while saving energy by quickly recovering waste heat with high efficiency.

생활수준의 향상으로 건물 실내공기의 질 향상과 웰빙에 대한 욕구가 높아지고, 새집증후군이 사회문제화 되면서 최근 국내에서도 집단 주거용 및 학교건물을 대상으로 환기설비가 의무화 되었고, 특히 자동차는 이제 이동수단을 넘어 하나의 생활공간으로 인식되고 자동차 실내 쾌적성의 중요요소중 하나인 공기의 질 향상이 요구 되고 있는 가운데 자동차 실내 환경은 다양한 소재의 내장재와 접착제가 밀폐된 자동차 실내의 좁은 공간에 사용되기 때문에 차량 실내에서 발생되는 유기용제(VOC), 냄새, 곰팡이, 미세먼지, 담배연기 등 각종 오염물질을 신속하게 배출해야 하고, 산소부족으로 인한 졸음방지와 보다 쾌적한 자동차 실내 환경조성을 위해 극 심하게 오염된 외기를 청정하게 처리해 공급하기 위한 여러 가지 수단으로 단순히 급기 및 배기만을 수동 또는 자동으로 행하는 환기장치가 실시되고 있지만 에어컨디셔너 가동 시 급배기를 동시에 행하지 않고 강제 배기만 행할 경우 오염된 외기가 틈새로 침입되며, 강재 급기만 행할 경우 틈새로 냉난방 된 공기가 유출되기 때문에 유출 또는 침입되는 공기 중의 에너지를 회수할 수 없으므로 막대한 에너지 손실이 발생하여 연비가 크게 저하되고 있다. 또한 환기 수단으로 창문 개방 시 에너지 손실뿐 아니라 소음과 매연의 침입으로 매우 열악하고 불쾌한 자동차 살내 환경을 피할 수 없게 되는 문제점이 있다. 또한 고유가 시대에 에너지 절약에 대한 요구가 더욱 크게 증대되고 있는 실정이다.Increasing living standards have increased the quality of indoor air quality and the desire for well-being, and the new house syndrome has become a social issue. Recently, ventilation facilities have been mandated in residential and school buildings in Korea. While improving the quality of air, which is recognized as a living space and one of the important factors in the comfort of the interior of the automobile, is required for the interior of the automobile, it is used in the narrow space of the interior of the automobile where various interior materials and adhesives are sealed. Various pollutants such as organic solvents (VOC), odors, mold, fine dust, and tobacco smoke should be discharged promptly, and extremely polluted outside air should be cleaned to prevent drowsiness due to lack of oxygen and to create a more pleasant environment for the automobile interior. Simply supply and exhaust as a means of processing and supply Although the ventilation system is operated manually or automatically, when the air conditioner is operated and only forced exhausting is performed without supplying and exhausting air at the same time, polluted outside air enters into the gap, and when only steel supply is performed, air is cooled and air leaked into the gap. In addition, since energy in the infiltrated air cannot be recovered, enormous energy loss occurs and fuel economy is greatly reduced. In addition, there is a problem that can not avoid the very bad and unpleasant car killing environment due to noise and smoke intrusion as well as energy loss when opening the window as a ventilation means. In addition, in the era of high oil prices, the demand for energy saving is increasing.

뿐만 아니라 대중교통수단인 지하철, 철도, 버스, 선박 등의 심각한 실내 공기 오염으로 실내 공기질 관리법 적용 대상에 포함 되어야 한다는 요구가 높아지고 있다.In addition, due to severe indoor air pollution of public transportation such as subway, railroad, bus, ship, etc., there is a high demand for inclusion in the indoor air quality management law.

본 발명은 상기의 문제점을 가장 적절하게 해결하기 위하여 창안된 것으로, 본 발명의 목적은 에어컨디셔너 가동 시 또는 환기 모드시 급기 및 배기를 동시에 행하여 폐열을 고효율로 회수하고 오염된 차량 실내공기를 신속히 배출하며, 청정한 외기를 차량실내로 공급하는 폐열회수 청정 환기를 제공하는데 있다.The present invention was devised to solve the above problems most appropriately, and an object of the present invention is to simultaneously supply and exhaust air during the operation of an air conditioner or a ventilation mode to recover waste heat with high efficiency and to quickly discharge contaminated indoor air. In addition, the present invention provides waste heat recovery clean ventilation for supplying clean outside air into a vehicle cabin.

상기의 목적을 달성하기 위한 본 발명의 구성은 차량용 폐열회수형 청정 환기장치에 있어서 통상의 차량 에어컨디셔너의 급배기 닥트와 연통되는 급기구와 배 기구를 갖는 케이스(100), 상기 급기구와 배기구 사이에 장착되는 전열교환소자(10), 급기구(20a), 외기구(20b), 급기 댐퍼(30a), 급기 바이패스 댐퍼(30b), 급기팬(40), 음이온 발생기(50), 배기구(60a), 흡입구(20b), 실내공기 여과필터(70), 배기팬(80), 외기 여과필터(90)로 구성함을 특징으로 한다.The configuration of the present invention for achieving the above object is a case (100) having a supply and exhaust mechanism in communication with the air supply and exhaust duct of a conventional vehicle air conditioner in a vehicle waste heat recovery type clean ventilation device, between the air supply and the exhaust port The heat exchange element 10, the air supply port 20a, the external device 20b, the air supply damper 30a, the air supply bypass damper 30b, the air supply fan 40, the negative ion generator 50, and the exhaust port 60a), the inlet port 20b, the indoor air filtration filter 70, the exhaust fan 80, the outside air filtration filter 90 is characterized in that the configuration.

이하 첨부한 도면2 도면3을 참조하여 본 발명의 실시에 따른 환기장치의 작동을 설명한다.Hereinafter, the operation of the ventilation device according to the embodiment of the present invention will be described with reference to FIG. 2.

먼저 사용자가 환기모드를 설정하게 되면, 급기팬(40)과 배기팬(80)이 동시에 가동되고 외기급기 덕트에 있는 급기 바이패스 댐퍼(30b)가 닫히고 급기 댐퍼(30a)가 열리면서 통상의 외기흡입 통로를 통해 오염된 외기가 통상의 에어컨디셔너의 외기 필터 또는 외기 여과 필터(90)에서 1차 여과되고, 열회수 효율이 높고 탈취, 탈가스 기능이 우수한 전열교환소자(10)를 통과하면서 배기되는 실내공기중의 전열, 즉 현열 및 잠열을 회수하면서 동시에 냄새, 매연 등으로 오염된 외기를 처리한 후 급기구(20a)에 설치된 음이온 발생기(50)에서 음이온을 발생함으로서 보다 청정한 공기를 차량 실내로 공급할 수 있다.First, when the user sets the ventilation mode, the air supply fan 40 and the exhaust fan 80 are operated at the same time, the air supply bypass damper 30b in the air supply duct is closed, and the air supply damper 30a is opened, and thus normal air intake is performed. The indoor air contaminated through the passage is first filtered by the air filter or the air filter 90 of the conventional air conditioner, and is exhausted while passing through the heat exchange element 10 having high heat recovery efficiency and excellent deodorization and degassing functions. It is possible to supply cleaner air to the vehicle interior by recovering the heat transfer, that is, the sensible and latent heat, and simultaneously treating the outside air contaminated with odor, smoke, etc. and then generating negative ions in the negative ion generator 50 installed in the air supply 20a. have.

배기 계통은 환기모드를 설정하게 되면 배기팬(80)의 가동에 의해 통상의 차량 실내공기 흡입구에 유입된 실내공기는 흡입구(60b)를 통하고 실내공기 여과장치(70)를 통과하면서 여과되고 전열교환소자(10)를 통과하면서 외기로 전열이 회수된 배기가 배기구(60a)를 통해 통상의 차량 배출그릴에 연통되어 차량 실외로 배출된다.When the exhaust system sets the ventilation mode, the indoor air introduced into the normal vehicle indoor air intake port by the operation of the exhaust fan 80 is filtered while passing through the indoor air filtration device 70 through the intake port 60b and is transferred. Exhaust whose heat is recovered to the outside air while passing through the exchange element 10 is communicated with the normal vehicle discharge grill via the exhaust port 60a and discharged to the outside of the vehicle.

상술한 바와 같이 본 발명에 따른 동시급배기 방식 페열회수형 청정 환기장치에 의하면, 차량 내부의 원활한 환기가 이루어져 에너지를 크게 절약하고, 오염된 차량 실내공기를 신속하게 배출하며, 청정한 외기를 차내로 공급함으로서 쾌적한 차량 실내공기 질을 향상 시켜 대중교통을 이용하는 국민 보건 향상에 크게 기여 하게 되며, 운전자의 산소부족으로 인한 졸음운전을 방지하여 사고예방 효과 또한 기대할 수 있다.As described above, according to the simultaneous exhaust type waste heat recovery type clean ventilator according to the present invention, a smooth ventilation is performed inside the vehicle, greatly saving energy, quickly discharging contaminated vehicle indoor air, and clean outside air into the vehicle. By providing a pleasant indoor air quality, it contributes greatly to the improvement of public health by using public transportation, and also prevents drowsy driving due to lack of oxygen of the driver.
