Title (EN) EJECTOR MODULE AND EJECTOR-TYPE REFRIGERATION CYCLE
(FR) MODULE ÉJECTEUR ET CYCLE FRIGORIFIQUE À ÉJECTEUR
(JA) エジェクタモジュール、およびエジェクタ式冷凍サイクル
Abstract:
(EN) This ejector module is provided with a nozzle part (15a), a depressurizing part (20b), a body part (21), a nozzle-side valve body part (22), a depressurizing-side valve body part (23), and a driving mechanism part (24). The nozzle part depressurizes and ejects a refrigerant. The depressurizing part depressurizes the refrigerant. The body part has: a refrigerant suction port (21b) which suctions the refrigerant from the outside by means of a suctioning action of an ejected refrigerant that is ejected from the nozzle part; and a pressure increasing part (15b) which increases the pressure of a refrigerant mixture of the ejected refrigerant and a suctioned refrigerant that is suctioned from the refrigerant suction port. The nozzle-side valve body part changes the cross-sectional area of the passage of the nozzle part. The depressurizing-side valve body part changes the cross-sectional area of the passage of the depressurizing part. The driving mechanism part displaces the nozzle-side valve body part and the depressurizing-side valve body part. The driving mechanism part closes the nozzle part earlier than the depressurizing part when closing the nozzle part and the depressurizing part from an open state, and opens the depressurizing part earlier than the nozzle part when opening the nozzle part and the depressurizing part from a closed state.
(FR) Le module éjecteur de l'invention comprend une partie buse (15a), une partie de dépressurisation (20b), une partie corps (21), une partie corps de soupape côté buse (22), une partie corps de soupape côté dépressurisation (23), et une partie mécanisme d'entraînement (24). La partie buse dépressurise et éjecte un fluide frigorigène. La partie de dépressurisation dépressurise le fluide frigorigène. La partie corps comprend : un orifice d'aspiration de fluide frigorigène (21b) qui aspire le fluide frigorigène depuis l'extérieur par une action d'aspiration d'un fluide frigorigène qui est éjecté par la partie buse; et une partie d'augmentation de pression (15b) qui augmente la pression d'un mélange du fluide frigorigène éjecté et d'un fluide frigorigène aspiré qui est aspiré par l'orifice d'aspiration de fluide frigorigène. La partie corps de soupape côté buse change la zone de section transversale du passage de la partie buse. La partie corps de soupape côté dépressurisation change la zone de section transversale du passage de la partie de dépressurisation. La partie mécanisme d'entraînement déplace la partie corps de soupape côté buse et la partie corps de soupape côté dépressurisation. La partie mécanisme d'entraînement ferme la partie buse avant la partie de dépressurisation lors de la fermeture de la partie buse et de la partie de dépressurisation se trouvant à l'état ouvert, et ouvre la partie de dépressurisation avant la partie buse lors de l'ouverture de la partie buse et de la partie de dépressurisation se trouvant à l'état fermé.
(JA) エジェクタモジュールは、ノズル部(15a)と、減圧部(20b)と、ボデー部(21)と、ノズル側弁体部(22)と、減圧側弁体部(23)と、駆動機構部(24)と、を備える。ノズル部は、冷媒を減圧させて噴射する。減圧部は、冷媒を減圧させる。ボデー部は、ノズル部から噴射された噴射冷媒の吸引作用によって外部から冷媒を吸引する冷媒吸引口(21b)、および噴射冷媒と冷媒吸引口から吸引された吸引冷媒との混合冷媒を昇圧させる昇圧部(15b)を有する。ノズル側弁体部は、ノズル部の通路断面積を変化させる。減圧側弁体部は、減圧部の通路断面積を変化させる。駆動機構部は、ノズル側弁体部および減圧側弁体部を変位させる。駆動機構部は、ノズル部および減圧部を開いた状態から閉塞させる際には、減圧部よりも先にノズル部を閉塞させ、さらに、ノズル部および減圧部を閉塞させた状態から開く際には、ノズル部よりも先に減圧部を開く。
