Abstract

본 발명은 정밀온도 제어에 적당하도록 한 온도 제어 방법 및 그 장치에 관한 것으로, 종래에는 온도 조절을 정밀하게 할수 없었으며 초기 구동후 정상동작까지 시간이 많이 걸렸으나, 본 발명에서는 비교부(3)및 구동부(5)사이에 정밀 제어부(9) 를 접속시켜 상기 정밀 제어부(9)알고리듬에 따라 설정 온도 및 히터(RL1)온도를 비교하여 히터(RL1)에 전력을 선택적으로 인가하므로써 원하는 온도를 정밀하게 제어할수 있으며 정상 동작에 도달하는 시간이 작고 에너지가 절감되므로 상기 결점을 개선시킬수 있는 것이다.The present invention relates to a temperature control method and apparatus for making it suitable for precision temperature control, and in the related art, it was not possible to precisely control the temperature and it took a long time until the normal operation after the initial driving. And a precision control unit 9 connected between the driving unit 5 and comparing the set temperature and the heater RL1 temperature according to the algorithm of the precision control unit 9 to selectively apply electric power to the heater RL1 to precisely adjust the desired temperature. The shortcomings can be improved since the time for reaching normal operation is small and energy is saved.
