FIELD: machine building.
SUBSTANCE: humidification assembly is intended for steam supply to air conditioning pipeline. Assembly (10) includes at least one tubular section (12) provided at least with one hole (16) so that vapour can leave inner part of tubular section (12) to its surface. Hole (16) is made through wall section (20) of tubular section so that inward directed annular projection (18) which composes an integral part with enveloping wall section (20) can be formed. Thus, projection (18) includes the material which is similar to that from which enveloping wall section (20) is made. Also, manufacturing method of such humidification assembly (10) is described by means of thermal drilling or stamping for creation of hole (16) and annular projection (18).
EFFECT: enhanced reliability.
