Estudio experimental de sistemas de ventilación en edificios como parte de la auditoria energética de sistemas hvac..

Néstor Fonseca Diaz; Jules Hannay

En este articulo se presentan los resultados de un estudio experimental realizado para evaluar el estado de funcionamiento del sistema de ventilacion en un edificio de tipo comercial. El problema se debe a que los ocupantes del edificioconsideran que la renovacion de aire es insuficiente y no permite asegurar las condiciones de confort en las oficinas. El objetivo de este estudio es dar algunas recomendaciones practicas sobre “Commissioning” de sistemas de distribucion de aire. Esta informacion y los procedimientos utilizados son de gran utilidad en la auditoria energetica de sistemas HVAC.

Auditoria energética de un sistema de enfriamiento tipo techo en aplicaciones HVAC/R.

Néstor Fonseca Diaz; Jules Hannay

El sistema de enfriamiento tipo techo de un edificio de tipo comercial en Bruselas Belgica es experimentalmente evaluado por medio de un procedimiento de ensayo y un modelo de calculo detallado del sistema. Este modelo es usado en terreno como herramienta de diagnostico en procesos de auditoria energetica (comissioning) para determinar el estado de funcionamiento de los principales parametros de operacion sistemas. El origen del problema: el sobrecalentamiento en algunas zonas del edificio debido a la enorme superficie vidriada. Los sistemas considerados para el commissioning son la fachada, el sistema de ventilacion y el sistema de enfriamiento tipo techo. Se evalua la interaccion y funcionamiento individual de cada uno de estos sistemas.

Thermal Model and Experimental Validation of Humidifier Systems as Commissioning Tools in HVAC Systems

Néstor Fonseca Diaz; Jean Lebrun; Jules Hannay

This paper presents the results of an experimental study performed to obtain a simplified model applicable to two adiabatic humidification systems: wetted wires and centrifugal atomizing. The aims of this study are to provide a model to be used in situ as a diagnosis tool in the commissioning of air-conditioning systems, and to develop a comparison between “wet” and “therma” effectiveness methodologies that also can be useful for the commissioning process. The model is able to predict the exhaust dry-air temperature, exhaust humidity ratio, and the humidifier effectiveness by using as inputs the supply-air temperature and relative humidity as well as the air and water mass flow rates. Simplicity and accuracy are the crucial factors. A series of tests are performed in order to validate the model.
