EJECTOR MODULE AND EVAPORATOR UNIT
Document Type and Number:
WIPO Patent Application WO/2018/159323
Kind Code:
A1
Abstract:
The ejector module is provided with a nozzle part (51), a depressurization part (20a), a body part (21), and a pressurization part (52). The body part has a refrigerant suction port (21b) through which a refrigerant is sucked in from the outside by a suction action of an ejected refrigerant ejected from the nozzle part. The refrigerant inlet side of a first evaporator (17) is connected to a throttle-side outlet (21d) through which the refrigerant flows out from the depressurization part. The refrigerant outlet side of the first evaporator is connected to the refrigerant suction port. The refrigerant inlet side of a second evaporator (18) is connected to an ejector-side outlet through which the refrigerant flows out from the pressurization part. At least one of the nozzle part and the depressurization part is configured such that the cross-sectional area thereof can be changed. At least a portion of the pressurization part is disposed to protrude from the body part so as to be able to be housed inside at least one of the first evaporator and the second evaporator or inside a pipe (19) connected to at least one of the first evaporator and the second evaporator.
