FIELD: human vital needs satisfaction.

SUBSTANCE: refrigerating unit with an evaporator (103) for refrigerant evaporation includes an inlet tube (105) for refrigerant inlet, containing a pipe region (107) with the first flow cross section and a narrowing region (109) with the second flow cross section. The second flow cross-section is smaller than the first flow cross-section. The narrowing region (109) is formed by several concave surfaces of the inlet pipe (105) wall. The pipe (105) is located on the outlet side of the throttling body.
