Résumé

This paper compares HVAC simulations between EnergyPlus and DOE-2.2 for data centers. The HVAC systems studied in the paper are packaged direct expansion air-cooled single zone systems with and without air economizer. Four climate zones are chosen for the study: San Francisco, Miami, Chicago, and Phoenix. EnergyPlus version 2.1 and DOE-2.2 version 45 are used in the annual energy simulations. The annual cooling electric consumption calculated by Energy-Plus and DOE-2.2 are reasonably matched within a range of -0.4 to 8.6%. The paper also discusses sources of differences between EnergyPlus and DOE-2.2 runs including cooling coil algorithm, performance curves, and important energy model inputs.
