Abstract
Description
본 발명은 에너지분야의 전력이용의 절감, 발전설비의 부하평준화를 위하여 사용되고 있는 빙축열시스템에 관한 것으로 빙축열시스템은 제빙방식에 따라 정적제빙방식과 동적제빙방식으로 분류되며 본 발명에 속한 동적제빙방식중 종래 기술은 얼음을 미세화하여 물 또는 동결억제재가 첨가된 수용액에 혼합하여 저장하였다가 필요시 부하측 고온의 순환수와 열교환하여 열에너지를 사용하는 것으로서 상용화된 기술로는 빙결완화제를 첨가한 수용액을 수직 다관식 열교환기의 관 내벽을 따라 흘리면서 관 외측에 있는 액냉매의 증발열에 의하여 냉각, 제빙시켜서 관에 설치된 ROD를 700~800RPM으로 휘저어 미세한 얼음 조각으로 만들어 관 하부로 배출하여 하부에 설치된 축열조에 저장하였다가 필요시 부하측과 열교환하는 Orbital Rod Evaporator 방식이 있다.The present invention relates to an ice heat storage system that is used to reduce power use in the energy field and load balancing of power generation facilities. The ice heat storage system is classified into a static ice making method and a dynamic ice making method according to the ice making method. The conventional technique is to refine the ice and mix and store it in an aqueous solution to which water or a cryoprotectant is added, and to use heat energy by exchanging heat with high temperature circulating water if necessary. Cooled and iced by the evaporative heat of the liquid refrigerant on the outside of the tube while flowing along the inner wall of the tube heat exchanger, the ROD installed in the tube was stirred at 700 ~ 800RPM to form fine ice cubes and discharged to the bottom of the tube and stored in the heat storage tank installed at the bottom. Orbital rod evaporator that exchanges heat with the load .
이 방식은 기계회전부의 고속회전으로 인한 내구성, 진동의 문제점과 정상운전시에도 축열수의 농도변화 및 관내의 과냉각도가 클경우 구동부가 파괴되는 단점과 정밀한 기계구조로 인한 제작 및 보수시 고숙련도 요구로 인하여 고가격 및 고비용이 단점 이다.This method requires durability and vibration problems due to the high-speed rotation of the mechanical rotating part, and the driving part is destroyed when the concentration of the regenerative water changes and the supercooling degree in the pipe is large even during normal operation. Due to the high price and high cost is a disadvantage.
또한 액냉매 직팽 Jacket을 외부에 설치한 원통형의 열교환기 내측에 빙결 완화제를 첨가한 수용액을 고속으로 선회시키어 수용액이 원심력에 의해 열교환기 내측벽으로 밀려 고속 및 고압상태에서 얇은 온도경계층이 될때 이때의 열전달로 인해 과냉각되어 형성된 얼음을 Screper로 깍아서 축열조에 저장하였다가 필요시 부하측과 열교환하는 Dynamic Direct 방식이 있으나 이 방식은 전술한 단점 외에 기계 자체가 소요 전열면의 크기로 인하여 커지는 단점이 있다.In addition, when the aqueous solution containing the freezing agent is added to the inside of the cylindrical heat exchanger in which the liquid coolant jacket is installed on the outside at high speed, the aqueous solution is pushed to the inner wall of the heat exchanger by centrifugal force to form a thin temperature boundary layer at high speed and high pressure. There is a dynamic direct method in which the ice formed by supercooling due to heat transfer is scraped with a screper and stored in the heat storage tank, and then heat-exchanged with the load side if necessary, but this method has a disadvantage in that the machine itself becomes larger due to the required heat transfer surface size.
본 발명은 종래기술의 문제점을 해소하기 위해 기구학적으로 기계가동부를 단순화하여 안정적인 운전 및 내구성을 향상시키며, 유지보수 및 관리에 별도의 기술이 필요없고, 원천적으로 과결빙에 의한 장치의 고장없이 더 높은 제빙효율로 시스템 성적계수 향상을 통한 저가의 에너지 절감기기를 만드는데 있다.In order to solve the problems of the prior art, the mechanical moving part is mechanically simplified to improve stable operation and durability, and does not require a separate technology for maintenance and management, and is essentially free from malfunction of the device due to freezing. It is to make low-cost energy saving device by improving system performance coefficient with higher ice making efficiency.
