Title:
EJECTOR MODULE AND EJECTOR-TYPE REFRIGERATION CYCLE
Document Type and Number:
WIPO Patent Application WO/2018/159322
Kind Code:
A1
Abstract:
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.
