EJECTOR
Document Type and Number:
WIPO Patent Application WO/2021/261112
Kind Code:
A1
Abstract:
This ejector is provided with: a drive-side nozzle part (31, 131); and a body part (32,132). The body part (32, 132) has a refrigerant sucking port (321), a sucking-side nozzle portion (322), a mixing portion (323), and a diffuser portion (324). A drive-side jetting port (31e) of the drive-side nozzle part (31, 131) and a sucking-side jetting port (322a) of the sucking-side nozzle portion (322) are opened so that the jetting direction of a drive-side jetted refrigerant and the jetting direction of a sucking-side jetted refrigerant are to be equivalent. The pressure of the drive-side jetted refrigerant is higher than the pressure of the sucking-side jetted refrigerant. The mixed refrigerant flowing from the mixing portion (323) to the diffuser portion (324) has a subsonic speed, and the refrigerant pressure thereof on the central axis side coincides with the refrigerant pressure on the wall surface side.
