METHOD AND APPARATUS FOR MEASURING THE QUANTITY OF OUTDOOR AIR PROCESSED BY AN AIR PRECONDITIONING MODULE

摘要

A method and system for determining the airflow through an air preconditioning module having a sensible and/or latent energy transfer matrix having a preestablished relationship between airflow and pressure drop. The air preconditioning module processes an inlet air stream so that it becomes a uniformly distributed (and preferably substantially laminar) outlet air stream leaving the energy transfer matrix of the preconditioning module. The pressure differential between the inlet air stream and the outlet air stream is determined and translated into an airflow value based on the pre-established relationship between airflow and pressure drop through the energy transfer matrix of the air preconditioning module.
