Generalidades, clasificación y requisitos. Reglas para la solicitud de oferta, la oferta, el pedido y el suministro.
Proporciona una clasificación de los sistemas, la definición de los requisitos mínimos y los valores de las grandezas de referencia durante el funcionamiento. Se aplica a los equipos aeráulicos destinados al bienestar de las personas, instalados en edificios cerrados, con la exclusión:
Actualmente, la norma se encuentra en una fase de revisión y, en lo que atañe a la clasificación de la calidad del aire interior y exterior, se han adoptado los conceptos de la norma 13779 y, sustancialmente, la clasificación es la misma:
Category | Description |
---|---|
ODA1 | Pure outdoor air that may temporarily contain dust (e.g. pollen) |
ODA2 | Outdoor air with a high concentration of particulate substances |
ODA3 | Outdoor air with a high concentration of gaseous pollutants |
ODA4 | Outdoor air with a high concentration of solid particles and gaseous pollutants |
ODA5 | Outdoor air with a very high concentration of solid particles and gaseous pollutants |
Category | Description |
---|---|
IDA 1 | High |
IDA 2 | Average |
IDA 3 | Moderate |
IDA 4 | Low |
La norma UNI 10339 facilita indicaciones también sobre los tiempos para el cambio del filtro:
A diferencia de la actual UNI 10339, su revisión determina la clase mínima de filtración no solamente según el destino de uso del edificio sino también en función del nivel de calidad buscado para el aire interior y del nivel de calidad del aire exterior disponible.
Asimismo, con contaminantes específicos conocidos presentes, en el sistema de eliminación asociado al circuito de ventilación adicional ha de haber por lo menos un filtro caracterizado por su eficacia certificada sobre dichos contaminantes.
“la sustitución de los filtros mecánicos para partículas se basa en general en la obstrucción de dichos filtros, indicada por las pérdidas de carga finales. Sin embargo, por razones higiénicas, los prefiltros y los filtros se han de inspeccionar periódicamente según la legislación vigente y las indicaciones del fabricante y sustituir, aunque las pérdidas de carga se consideren aceptables, cuando se produzcan fenómenos de contaminación biológica”
