Determination of k-factors for HVAC system components.

Auteurs : GAN G., RIFFAT S. B., SMITH S. J., et al.

Résumé

The k-factors of duct fittings provided by the CIBSE and the ASHRAE are used extensively by HVAC system designers. Existing guides published by the two institutions do not include many of the duct fittings used in HVAC systems and they neglect to consider parameters which affect k-factors. More importantly, there are large errors in some of the data. The paper presents a study in which experiments and computational fluid dynamics were applied to determine k-factors. The predicted k-factors were compared with experimental results and the data from the literature.
