Abstract

A liquid nitrogen and electric motor car using a heater pump is provided to drive a car fast by generating huge pressure by using a low boiling point of liquid nitrogen. A liquid nitrogen and electric motor car using a heater pump comprises a liquid nitrogen tank(1), a waste heat recovery unit, an external air heat exchanger(4), a liquid heat exchanger(8), a heat pump, and a condenser. The liquid nitrogen tank compresses and transfers liquid nitrogen to the waste recovery unit by using a nitrogen pump(2). The waste heat recovery unit evaporates the liquid nitrogen. The external air heat exchanger re-evaporates the liquid nitrogen by using a fan. Nitrogen gas is injected to the liquid heat exchanger. The condenser and the tank are filled with an antifreezing solution. The liquid heat exchanger heats the condenser and the tank by using the heat pump and liquefies a refrigerant.

현재 사용 중인 자동차의 내연기관은 배기가스로 인한 대기오염과 낮은 연료 효율과 화석연료의 고갈 등으로 차세대 엔진으로 발전단계로 전기자동차 연료전지 압축공기 자동차 등으로 연구개발하고 있으나 수소를 이용한 연료전지 차가 상용화가 되어 있으며 수소생산과 저장 경제성 등 여러 가지 문제점이 있으며, 본 발명은 액체질소와 축전지를 이용한 전기모터를 겸용으로 사용하므로 한층 효율을 높인 것으로 압축 가스 보다도 많은 양의 질소를 저장하므로 장시간 주행할수 있으며 액체질소 체적당 기화시 900배로 확산 되며 사용 시 압력 저하가 없으므로 주행 성능에는 지장이 없고 기동시 에는 전기모터로 운행하며 일정속도 이상이면 질소가스로 전환되며 터빈을 회전시키며 같은 축에 연결된 발전기겸용 기동모터로 발전하여 히터펌프용 전동기 액체질소펌프 전동기 실외기 열교환기 휀용 전동기 등에 전원을 공급 한다 현재의 가솔린엔진 디젤엔진은 이미 환경공해로 폐기 되어야 되며 기타 압축공기 자동차와 수소연료를 사용하는 자동차의 문제점을 해결한 것이다 기존의 액체질소를 자연적인 방법으로 기화시켜 시험적인 LN 2000과는 한차원 다른 방법으로 모든 문제점을 해결된 차세대 환경 친화적 자동차이다The internal combustion engine of automobiles currently in use is being researched and developed as a next generation engine due to air pollution from exhaust gas, low fuel efficiency and depletion of fossil fuels. It has been commercialized and has various problems such as hydrogen production and storage economics. The present invention uses an electric motor using liquid nitrogen and a storage battery as a combination of the above to improve the efficiency. It is diffused 900 times per volume of liquid nitrogen, and there is no pressure drop during use, so there is no problem in running performance, it operates by electric motor at start-up, it converts to nitrogen gas when it is over a certain speed, turns turbine and rotates turbine. Generated as starting motor for heater pump Synchronous Liquid Nitrogen Pump Electric Motor Outdoor Unit Heat Exchanger Power Supply to Electric Motors etc. Current gasoline engine Diesel engine has already been disposed of as environmental pollution and solves the problems of other compressed air vehicles and vehicles using hydrogen fuel. Is a next-generation environmentally friendly vehicle that evaporates all the problems in a different way than the experimental LN 2000 by vaporizing in a natural way.

본 발명은 상기한 문제점을 해소하고자 창출한 것으로서 액체질소를 자연적인 상온의 공기와의 열교환으로 액체질소를 기화시켜 질소압력을 발생하는 것이 아닌 고성능의 히터펌프를 이용하여 부동액속의 열교환기에 히터펌프의 응축열량을 방출하여 액체질소의 기화를 촉진 시킴과 더불어 높은 질소의 체적팽창을 이용하여 용적형 팽창터빈을 구동하므로 질소가스의 소비를 억제하므로 기존의 원심형 터빈을 능가하는 효율을 이룩함과 동시에 터빈의 같은 축에 연결된 발전기 (모터)를 구동하여 축전기를 축전시킴과 동시에 장치내의 히터펌프 압축기 모터 액 펌프 실외 냉각 휀 모터 등에 전원을 공급 한다.The present invention has been made to solve the above problems, liquid nitrogen is not produced by the heat exchange with natural air at room temperature to vaporize the liquid nitrogen to generate a nitrogen pressure rather than using a high-performance heater pump of the heat pump in the antifreeze heat exchanger By discharging the heat of condensation to promote the vaporization of liquid nitrogen and driving the volumetric expansion turbine by using the high volumetric expansion of nitrogen, it suppresses the consumption of nitrogen gas and achieves efficiency exceeding the existing centrifugal turbine. It operates the generator (motor) connected to the same shaft of the turbine to power the capacitor and supplies power to the heater pump compressor motor liquid pump outdoor cooling fan motor in the unit.

상기 목적을 달성하기 위하여 영하196℃의 액화 질소를 빠르게 기체로 기화하기 위하여 1번 액체질소 탱크와 2번 액체질소 펌프 와 3번 터빈을 돌린 후 배기되는 배열과 액체질소와 의 열교환으로 배열회수기(에코너마이져) 14번 역지변 13번 전자변 4번 액체질소 외기열교환기 8번 부동액 열교환기 10번 압력조절밸브 9번 용적식 터빈 11번 발전기 및 기동모터 16번 동력전달 장치 5번 히터펌프용 증발기 12번 실외 휀 5번 히터펌프용 팽창변 6번 히터펌프용 2단압축기 7번 압축기용 모터 등으로 구성되며 히터펌프 사이클은 냉매가 탄산가스(CO2) 2단 압축 시스탬 으로 평균 성적계수 COP 5-10을 나타내는 급탕전용 히터펌프를 채택함 먼저 축전기로 모터를 기동함과 동시에 정상속도에 이르면 액체질소는 2번 펌프로 3번 배열 회수기로 유입 되어 13번 전자변을 거처 4번 외부열교환기 에서 외기와 열교환 한 후 8번 부동액으로 가득찬 액체 열교환기 내부는 이미 히터펌프 응축으로 부동액을 25℃정도로 가온된 상태로 질소가스와 의 열교환 으로 질소기체는 체적 팽창을 한다 이때 10번 압력조절기가 압력을 30BAR정도 로 유지면서 9번 터빈으로 유입되며 터빈을 구동 시키며 모터를 발전기로 전환하며 장치내부의 전원공급과 축전을 한다. 터빈을 나온 질소기체는 배열회수장치 3번으로 들어가서 액체 질소와 열교환 하여 액체질소를 기화 시킨다.In order to achieve the above object, in order to quickly vaporize liquefied nitrogen at minus 196 ° C into a gas, a heat recovery device is formed by turning the liquid nitrogen tank 1, the liquid nitrogen pump 2, and the turbine 3, and then evacuating the exhaust gas and heat exchange with the liquid nitrogen. Economizer) No. 14 Reverse valve No. 13 Electronic valve No. 4 Liquid nitrogen External air heat exchanger No. 8 Antifreeze heat exchanger No. 10 Pressure control valve No. 9 Volume turbine No. 11 Generator and starting motor No. 16 Power train No. 5 Heater pump Evaporator No. 12 Outdoor 휀 No. 5 Heater Pump Expansion Valve No. 6 Heater Pump No. 2 Compressor No. 7 Compressor Motor, etc. Heater pump cycle consists of refrigerant CO2 (CO2) two-stage compression system. Adopt a heater pump for hot water supply which shows 10. First, when the motor is started with a capacitor and the normal speed is reached, the liquid nitrogen flows into the heat recovery unit 3 through 2 pumps and passes through 13 electronic valves. After exchanging air with outside air in No.4 external heat exchanger, the inside of the heat exchanger filled with antifreeze No.8 is already heated to 25 ℃ by condensation of the heater pump, and the nitrogen gas expands by heat exchange with nitrogen gas. Pressure controller 10 enters turbine No. 9 while maintaining the pressure at about 30 BAR. It drives the turbine, converts the motor into a generator, and supplies power to and accumulates power inside the device. Nitrogen gas from the turbine enters heat recovery unit 3 and heat-exchanges with liquid nitrogen to vaporize the liquid nitrogen.

5KW의 히터펌프 입력열량은 5x860=4.300Kcal/h 출력열량은 평균 COP7 정도이면 7x5x860=30.100Kcal/h 의 열량을 부동액 열교환기에 주입시켜 냉매는 응축 한 다.If the input heat of 5KW heater pump is 5x860 = 4.300Kcal / h and the output heat is average COP7, 7x5x860 = 30.100Kcal / h is injected into the antifreeze heat exchanger to condense the refrigerant.

여름철 최대 5x10x860=43.000Kcal/h 이므로 충분한 경제성이 있으며 액체질소1kg의 증발잠열은 압력에 따라 다르나 평균4kg/㎠ 일때 42Kcal/kg 이므로 만약100kg을 증발하여 0도의 기체로 만들시 100x42=4.200Kcal의 잠열과 헌열 100x0.24x196=4.704Kcal 로 전체의 열량합계4.200+4704=8.904Kcal이며 25℃로 온도를 상승해도 25x100x0.24=600Kcal로써 합계 열량9.504Kcal 이므로 히터펌프 외에 외기를 이용한 증발열량을 감안하면 실로 큰 열량을 이용하고도 남는 열량이다.The maximum economic efficiency in summer is 5x10x860 = 43.000Kcal / h, which is sufficient economic efficiency. The latent heat of vaporization of 1kg of liquid nitrogen depends on the pressure, but it is 42Kcal / kg when the average is 4kg / ㎠. The total calorific value of total heat is 4.200 + 4704 = 8.904Kcal with 100x0.24x196 = 4.704Kcal, and even if the temperature rises to 25 ℃, the total calorie is 9.04Kcal with 25x100x0.24 = 600Kcal. It is the amount of calories left over by using large calories.

전체 액화질소 증발열량100kg=약10.000Kcal 를 7시간에 전체 소비하면 시간당1.429Kcal/h 소비하며 히터펌프의 인버터 모터는 약2KW 정도이면 됨 액체질소의 중량 체적과 의 증발 기체 체적의 약900배 기체로 확대 되면 큰 압력을 제공 할 수 있다. 또한 히터펌프의 열량으로 외부의 열교환기의 성애도 터빈을 통과한 배기 배열과의 열 회수로 액체질소는 기화하여 외부 열교환기에 성애의 영향을 크게 줄 수 없으며 적은 량의 액체질소를 이용하여 큰 동력을 이룰수 있는 방법이 히터펌프의 효율을 이용함에 있다. 또한 용적식 터빈을 사용함으로 누설 및 바이페스 되는 공기량을 극소화 함으로 성능을 더 향상 할 수 있다.Total consumption of liquid nitrogen evaporation heat 100kg = about 10.000 Kcal in 7 hours consumes 1.429 Kcal / h per hour and the inverter motor of the heater pump is about 2KW. About 900 times the volume of liquid nitrogen and the volume of evaporation gas between If enlarged, it can provide great pressure. In addition, the heat of the heat pump and the heat of the external heat exchanger and the heat recovery from the exhaust heat passing through the turbine vaporize the liquid nitrogen so that the external heat exchanger can not affect the frost significantly. One way to achieve this is to use the efficiency of the heater pump. In addition, the use of volumetric turbines can further improve performance by minimizing leakage and bypassed air volume.

상기와 같이 이루어지는 본 발명은 공기중의 78％인 질소를 이용하므로 환경적으로 무해하며 소형의 히트펌프를 이용하여 외기의 무한한 열량을 이용하여 액체질소의 낮은 비점을 이용하여 큰 압력을 발생하여 이를 동력으로 발전과 축전하여 자동차를 고속으로 주행 할수 있다The present invention made as described above uses 78% of nitrogen in the air, which is environmentally harmless, and uses a small heat pump to generate a large pressure using a low boiling point of liquid nitrogen using infinite heat of outside air. Power generation and power storage can drive cars at high speed
