ELEMENTOS COMPLEMENTARIOS PARA AIRE ACONDICIONADO

DUCTOS

Características Generales

Los ductos de aire son los elementos de una instalación a través de los cuales se distribuye el aire por todo el sistema. Sus propiedades determinan en gran parte la calidad de la instalación, ya que son fundamentales para determinados factores, como el aprovechamiento
energético y el comportamiento acústico. Para el buen funcionamiento del sistema de aire acondicionado los ductos deben estar bien dimensionados, dependiendo del flujo de aire que van a transportar, tomando en cuenta que este dimensionamiento se hace con factores  que ya están normados.

Para la adecuada distribución del aire las dimensiones de los ductos se van haciendo más pequeños a medida que se distribuye el flujo de  aire de la red principal hacia sus ramificaciones, las cuales llevan la cantidad necesaria dependiendo el volumen del espacio y este será  inyectado a través de difusores.

Este flujo que ya ha sido previamente calculado en el diseño de los ductos será corroborado por un aparato llamado bolómetro, teniendo  este dato si es necesario se hará ajuste al flujo de aire por medio de dampers que se encuentran dentro de los ductos.

Requisitos de Instalación

Para que se lleve a cabo una correcta instalación de los ductos se debe contar con un espacio mínimo de 14” de entre las vigas de la losa y  el cielo falso. El diámetro de las tuberías debe tener una relación de 3 a 1, esto quiere decir que el alto nunca será menor del ancho del  ducto (mientras más proporcional sean las dimensiones, el ducto será más eficiente).

Los ductos no deben de ser instalados sobre las luminarias por lo que debe de haber una coordinación de diseño eléctrico y aire  condicionado.

Dependiendo del tipo de ducto que se instalado así será el anclaje a la losa o viga.

Tipos de Ductos

Ducto Flexible.

Este tipo de ducto es de forma circular puede ser sin aislamiento o con aislamiento de fibra de vidrio y forro exterior de doble película de  poliéster metalizado reforzada como barrera de vapor (contra la evaporación) y en su interior con doble película de fibra de vidrio con un  resorte de acero templado.

El ducto flexible es instalado por medio de una platina que se pone alrededor de este y luego se fija a la losa o polín por medio de una  varilla roscada.

Ducto Rígido

Este tipo de ducto es de forma circular o rectangular de lámina galvanizada, con aislamiento o sin aislamiento térmico, generalmente este
aislamiento se coloca por secciones antes de que el ducto sea instalado, este aislamiento es de fibra de vidrio de 1.5”, este no debe ser  comprimido y se utiliza pegamento no flamable.
