Claims (2)

  1. 냉매와 소량의 오일이 순환하는 순환회로가 응축기(4), 팽창밸브(5) 및 증발기(6)와 함께 스크루우압축기로 형성되는 시스템의 일부를 스크루우 압축기(1)의 작업실을 냉각하고 밀봉하여 윤활시키는 냉동 시스템의 방법에 있어서, 압축기(1)로 부터 냉매와 오일전량을 응축기(4)에 공급하기 위하여 압축기(1)의 출구가 응축기(4)의 입구에 직결되고, 증발기(6) 내에서와 같은 압력 및 온도이거나 이에 가까운 것이 바람직한, 응축기(4)의 냉매와 오일의 압력과 온도보다 낮은 압력과 온도의 냉매액체포함 오일이 거의 모든 소망의 냉각과 밀봉이 냉매 액체에 의해 얻어질 수 있는 단위시간당 양으로 압축기(1)의 저압측에 공급되여, 냉매 액체내의 잔존오일의 양이 로터의 적당한 윤활을 위한 소정의 값으로 제한되는 것을 특징으로 하는 냉동 시스템을 위한 방법.
  2. 제1항에 있어서, 팽창밸브(5)와 증발기(6) 사이의 파이프내 또는 증발기로 부터의 냉매액체 포함오일이 수집되어 특정의 파이프(7)를 개재하여 압축기의 저압측(2), 바람직한 것은 감소된 압력의 나사부(9)에 공급되는 것을 특징으로 하는 냉동시스템을 위한 방법.
