Abstract:
A method for determining the airflow through an air preconditioning module having a sensible and/or latent energy transfer matrix in which there is a pre-established relationship between the airflow through the matrix and the pressure drop across the matrix, the air preconditioning module having a first means for processing an inlet air stream so that it becomes a uniformly distributed and substantially laminar outlet air stream, said method comprising the steps of:(a) feeding an inlet air stream through the air preconditioning module;(b) processing the inlet air stream using the first means so that the inlet air stream becomes a uniformly distributed and substantially laminar outlet air stream exiting the energy transfer matrix of the preconditioning module;(c) determining the pressure differential between the inlet air stream and the outlet air stream; and(d) translating the pressure differential into an airflow value based on the pre-established relationship between airflow through and pressure drop across the energy transfer matrix of the air preconditioning module.
