Resumen
In some places it is not possible to install equipment that blow air directly in
environmental conditioning. In these cases it is necessary to conduct the air till the
environmental through ducts network. This work is a presentation the means used to
transport the air conditioning or ventilation, as well as an analysis of the methods used
in the design of these means and the presentation of a computer program developed in
EXCEL for sizing ducts. The sizing should consider the available space, space air
diffusion, noise, leaks in ducts, gains or losses of heat, balance, control of smoke and
fire and costs. This work also object to provide the procedure for selection of
accessories (registers,, grilles and diffusers) used in the process of conducting the air.
To do this, known abacus and equations were used to calculate the pressure drop such
as the continuity equation, the general equation for calculating the pressure drop and the
abacus Moody. This work also includes a literature review on the main components of
air operation. The data were processed and analyzed, and a discussion is presented,
showing the influence that each of these points on the functioning and efficiency of air
transport and distribution.
