Claims

[Scope of utility model registration request]

The refrigerant is heated and evaporated using engine heat,
a heater that produces high-pressure steam; a condenser that condenses and liquefies refrigerant vapor; a first connecting pipe that has one end connected to the steam outlet of the heater and the other end connected to the steam inlet of the condenser; One end is connected to the ejector, which is installed in the middle of one connecting pipe and spouts the steam sent from the heater toward the condenser, and sucks the fluid from the suction port installed on the side, and the outlet of the liquid refrigerant of the condenser. a second connecting pipe whose other end was connected to the inlet side of the evaporator for evaporating this liquid refrigerant, and a third connecting pipe whose one end was connected to the outlet side of this evaporator and the other end was connected to the suction port of the ejector. An ejector for a steam injection refrigerator that is used by being incorporated into a steam injection refrigerator, which comprises a connecting pipe and a branch pipe that branches from the middle of the second connecting pipe and leads to the liquid refrigerant inlet of the heater. ,
Inside the other end of a cylindrical chamber with the base of the diffuser connected to one end and the suction port connected to the outer circumferential surface, a sliding block with a nozzle for ejecting driving refrigerant gas fixed in the center is attached to the shaft of the chamber. An O-ring is fitted between the outer circumferential surface of the sliding block and the inner circumferential surface of the chamber to maintain airtightness between both surfaces, and the outer circumference of the other end of the chamber is fitted so that it can freely slide in any direction. The inner periphery of the end of the adjustment cylinder, in which the female thread formed on the inner periphery is screwed together with the male thread engraved on the surface, and the outer periphery of the end of the sliding block are connected over the entire circumference of one part. An ejector for a steam injection type refrigerator, characterized in that the ejector is engaged with each other by fitting a protrusion formed on the other part into an engagement groove formed on the other part.
