摘要：The article primarily presents a schematic idea of the operation
of innovative ventilation shapes with adjustable performance. Then, it was
pre-verified by measuring static pressure on the walls of ordinary fittings
and innovative T-type fittings. The presented fittings have features that
allow for very precise control of the performance of ventilation streams in
various configurations. The most important diagrams in the article show
that there are simple methods for distributing air streams, even in mutually
perpendicular channels leading to minimized flow losses. The presented
results of comparative tests carried out on ordinary and innovative
T-shaped fittings show very favorable tendencies which are characterized
by a several-dozen-percent drop in pressure in similar measurement ranges.
