Abstract

Se proporcionan un aparato y un método para determinar indirectamente la cantidad de aire exterior introducido en el sistema de ventilación de una estructura, para controlar la calidad del aire interior en la estructura. Se miden las concertaciones del gas de prueba, de preferencia concentraciones de dióxido de carbono para el aire de retorno, el aire exterior y el aire mezclado (de abastecimiento). Se mide la velocidad de flujo del aire mezclado. El volumen del aire exterior introducido en el sistema, se determina por el uso de las mediciones de la concentración de gas de prueba sin la medición directa del volumen o velocidad de flujo del aire exterior. De preferencia, se utiliza un detector individual para abrir cada una de las concertaciones de gas en trazas en el aire de retorno, el aire exterior y el aire de abastecimiento y las diversas mediciones se multiplejan secuencialmente a un controlador. Además, para calibrar el aparato, un detector de aire de retorno es calibrado para el aire exterior y un detector de aire mezclado es calibrado para el aire exterior o el aire de retorno para eliminar la inexactitud o el error debido al desplazamiento del detector.
