Abstract

원심력식 냉동 컴프레서는 적어도 임펠러(17,18), 전기 모터(27)및 컴프레서 하우징(12)에 대하여 축방향의 움직임을 제한하기 위하여 샤프트에 연결된 축방향 로케이팅 수단과 함께 비윤활성 래디얼 베어링상에 장착된 구동 샤프트(22), 예를 들면 마그네틱 또는 포일 가스 베어링(23,24)을 포함한다. 하우징(12)은 모터(27)와 컴프레서를 둘러싸고 가스 인렛(31)과 가스 아웃렛(16) 통로를 구성한다. 가스 트로틀링 수단(34)은 인렛(31)내에 제공되고 컨트롤 수단(30)은 트로틀링 수단(34)과 모터의 속도를 변화시켜 냉동 부하에 따라 컴프레서를 통한 컴프레션 비율 및 매스 흐름을 조절한다.
