Extending the concept of energy delivery efficiency (EDE) of HVAC systems.

Author(s) : REDDY T. A., LIU M., KATIPAMULA S., CLARIDGE D. E.

Summary

An earlier study advanced the concept of EDE of HVAC systems by which energy mixing in large commercial buildings can be evaluated against an absolute energy standard, namely, the energy needs of the building if operated as a one-zone building. The study also pointed out that this EDE (1-zone) is an upper limit, and that the efficiency of the two-zone building, which term is EDE (2-zone), would constitute a more realistic energy standard. The mathematical treatment, previously limited to dealing with sensible heat flows, has been expanded in the study to cover supply air latent effects as well as the influence of economizer operation.
