Title:
EJECTOR MODULE
Document Type and Number:
WIPO Patent Application WO/2019/017169
Kind Code:
A1
Abstract:
This ejector module is provided with a nozzle part (51), a body part (21), a pressure raising part (52), a depressurization part (20a), a depressurization-side valve body part (61), a depressurization-side driving part (62), and an opening/closing mechanism (27). The body part is provided with a refrigerant suction port (21b) which suctions a refrigerant from the outside. The pressure raising part raises the pressure of a refrigerant mixture of an injected refrigerant and a suctioned refrigerant suctioned from the refrigerant suction port. The depressurization part depressurizes a portion in the refrigerant discharged from an outdoor heat exchanger (16). A refrigerant inlet side of an intake-side evaporator (17) is connected to a throttle-side outlet (21d) from which the refrigerant passed through the depressurization part is discharged. A refrigerant inlet side of an outflow-side evaporator 18 is connected to an ejector-side outlet (21c) form which the refrigerant passed through the pressure raising part is discharged. The body part is provided with a bypass passage (20e) which makes the refrigerant discharged from the outdoor heat exchanger bypass the depressurization part and guides the refrigerant to a throttle-side outlet. The opening/closing mechanism opens/closes the bypass passage.
