Claims

[Scope of utility model registration request]

A heater that heats and evaporates refrigerant into high-pressure vapor, and a condenser that condenses and liquefies the refrigerant vapor.
A first connecting pipe with one end connected to the steam outlet of the heater and the other end connected to the steam inlet of the condenser, and a pipe provided in the middle of this first connecting pipe to direct the steam sent from the heater to the condenser. Squirt towards the
an ejector that sucks fluid from a suction port provided on the side; a second connecting pipe that has one end connected to the outlet of the liquid refrigerant of the condenser and the other end connected to the inlet side of the evaporator that evaporates the liquid refrigerant; A third connecting pipe has one end connected to the outlet side of the evaporator and the other end connected to the suction port of the ejector, and a third connecting pipe branches from the middle of the second connecting pipe and leads to the liquid refrigerant inlet of the heater. In a steam injection type refrigerator consisting of a branch pipe, a casing having a flow path area sufficient to not create resistance to the flow of refrigerant gas is provided behind the diffuser provided behind the nozzle of the ejector, and this A heat exchange core consisting of a heat exchanger tube and a plurality of fins arranged parallel to the flow of refrigerant in the casing and spaced apart from each other is installed in the casing, and the heat exchanger tube is placed in the middle of the branch tube. A steam injection refrigerator characterized by being connected in series.
