Textile ducts - a good alternative for ventilation of
Together with two graduates at the University of Aalborg, Denmark,
KE Fibertec AS has made tests of
comfort, air quality, and air flow in offices ventilated by textile
ducts. A number of measurements were
made of the KE-Interior System both as traditional
low impulse ventilation with passive
thermal displacement and using the new hybrid
KELaserInject System for active
The setup of a number of design criteria of the two systems
involved the preparation of so called
design charts designated to compare other types of ventilation
units. Tests of both systems have
shown that the permitted range of variation is considerably bigger
for textile ducts than for
traditional units for mixing and displacement ventilation.
Further the tests have shown that textile ducts create good air
distribution and air quality. CFD
simulations of air flows and conditions of temperature and
concentration have also shown that a
computer simulation is a well suited tool to predict room air
conditions in offices.
