Description

냉동회로
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제 3 도는 본 발명의 1실시예의 따른 냉동회로의 간략도,
제 4 도는 제3도의 냉동회로에서 사용하기 위한 유량 제어장치의 횡단면도,
제 5 도는 증발기의 냉각용량과 압축기의 회전속도 사이의 관계를 나타내는 그래프.

Claims (3)

  1. 압축기와, 응축기, 증발기 및 축압기를 포함하고 압축기로부터 방출된 냉매가 상기 응축기와 증발기, 상기 축압기를 통해 흘러 상기 압축기의 흡입구로 귀환되게한 냉동회로에 있어서, 상기 응축이의 출구측에서의 냉매 차냉각 값을 검출하는 것에 의해 냉매의 유량을 제어하도록 상기 응축기의 출구측에 배치된 차냉각 제어 밸브 수단과, 그리고 상기 증발기로 흘러들어가는 상기 냉매의 유량의 변화를 조절하도록 상기 차냉각 제어 밸브 수단에 직접적으로 연결된 고정트로틀 밸브 수단을 포함하는 것을 특징으로 하는 냉동회로.
  2. 제 1항에 있어서, 상기 차냉각 제어 밸브 수단이 상기 고정 트로틀 밸브 수단과 일체로 형성되어 있는 것을 특징으로 하는 냉동회로.
  3. 제1항에 있어서, 상기 차냉각 제어 밸브 수단은 상기 응축기의 출구쪽에서 냉매의 압력 및 온도를 검출하는 검출 센서로부터 보내져오는 전기적 신호에 따라 작동되는 것을 특징으로 하는 냉동회로.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
