Claims (2)

  1. 압축기(21), 응축기(22), 냉매유량조절 밸브(24), 증발기등으로 구성된 냉동장치의 온도제어방법에 있어서, 피냉각부의 온도를 검출하고, 또한 검출된 온도에 기초를 두어서 상기한 유량조절밸브의 개방도를 조점하기 위한 제1제어신호(M1)를 형성하며, 상기한 증발기 출구쪽의 냉매가스의 온도와 압력을 검출하고 또한 그들의 값에서 냉매가스의 과열도를 연산하여 그 과열도에 기초를 두어서 상기한 밸브의 개방도를 조점하기 위한 제2제어신호(M2)를 형성하며, 상기한 제1제어신호와 제2제어신호를 비교하여서 적은쪽의 제어신호를 선택적으로 상기한 유량조점밸브에 출력하여 밸브의 개방도를 조점하는 것에 의하여 피냉각부의 온도를 제어하는 것을 특징으로 하는 냉동장치의 온도제어방법.
  2. 제1항에 있어서, 상기한 연산된 과열도가 사전에 결정된 설정과 열도 이하로 되었을 때에는 상기한 제2제어신호(M2)가 제1제어신호(M1)보다도 적게되도록 설정되어 있는 것을 특징으로 하는 냉동장치의 온도제어방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
