Claims

[Scope of utility model registration request]

A refrigeration system in which refrigerant is ejected through a narrow-section aperture opening into a space whose cross-section is larger than that of the outlet, thereby generating a jet core having equipotential energy from the outlet into the space. , an obstacle having a surface having a cross-sectional area larger than the cross-sectional area of the outlet portion is disposed within a distance five times the diameter of the outlet portion from the outlet end face. vessel.
