Title (EN) SCROLL COMPRESSOR
(FR) COMPRESSEUR À SPIRALE
(KO) 스크롤 압축기
Abstract:
(EN) Provided is a scroll compressor in which an installation position of a check valve is optimized, such that a back flow of a refrigerant is prevented at the time of stopping of the scroll compressor, flow noise can be reduced, the refrigerant sucked in by the scroll compressor can be efficiently distributed to a compression chamber and a drive unit. The scroll compressor comprises: a main body; a fixed scroll fixedly installed in the main body; an orbiting scroll which is engaged with the fixed scroll and performs a relative orbiting motion and forms a compression chamber with the fixed scroll; a high-low-pressure separation plate disposed above the fixed scroll and separating the inside of the main body into a low-pressure portion and a high-pressure portion; a first check valve, installed at a discharge port of the fixed scroll, for opening and closing the discharge port; and a second check valve, installed on an upper portion of the high-low-pressure separation plate, for opening and closing an opening connecting the low-pressure portion and the high-pressure portion.
(FR) La présente invention concerne un compresseur à spirale dans lequel une position d’installation d’un clapet de non-retour est optimisée, de sorte qu’un retour d’un fluide frigorigène est évité au moment de l’arrêt du compresseur à spirale, le bruit d’écoulement peut être réduit, le fluide frigorigène aspiré par le compresseur à spirale peut être distribué efficacement vers une chambre de compression et une unité d’entraînement. Le compresseur à spirale comprend : un corps principal ; une volute fixe installée de façon fixe dans le corps principal ; une volute orbitale qui est en prise avec la volute fixe et effectue un mouvement orbital relatif et forme une chambre de compression avec la volute fixe ; une plaque de séparation haute pression-basse pression disposée au-dessus de la volute fixe et séparant l’intérieur du corps principal en une partie basse pression et une partie haute pression ; un premier clapet de non-retour, installé au niveau d’un orifice d’évacuation de la volute fixe, pour ouvrir et fermer l’orifice d’évacuation ; et un deuxième clapet de non-retour, installé sur une partie supérieure de la plaque de séparation haute pression-basse pression, pour ouvrir et fermer une ouverture reliant la partie basse pression et la partie haute pression.
(KO) 체크밸브의 설치위치를 최적화 하여 스크롤 압축기의 정지 시 냉매의 역류를 방지하고, 유동소음을 저감할 수 있고, 스크롤 압축기로 흡입되는 냉매가 압축실과 구동유닛에 효율적으로 분배되어 전달되도록 하는 스크롤 압축기를 제공한다. 스크롤 압축기는 본체, 상기 본체 내부에 고정 설치되는 고정스크롤, 상기 고정스크롤과 맞물려 상대 선회 운동을 하며, 상기 고정스크롤과 압축실을 형성하는 선회스크롤, 상기 고정스크롤의 상부에 위치하며, 상기 본체 내부를 저압부와 고압부로 구분하는 고저압분리판, 상기 고정스크롤의 토출구에 설치되어 상기 토출구를 개폐하는 제1체크밸브 및 상기 고저압분리판의 상부에 설치되며, 상기 저압부와 상기 고압부를 연통시키는 개구를 개폐하는 제2체크밸브를 포함한다.
