Re-Commissioning of a VAV Air-Distribution System
MetadataShow full item record
Three years after its start up, the building considered here is not yet providing a satisfactory comfort to its occupants. Too cold and too hot environmental conditions were too often encountered in different occupied zones, mainly in midseason and in summertime. The execution of a re- commissioning process would support in resolving these problems. Previous verifications allowed us to confirm that almost all HVAC components considered are technically “correct” and that almost all problems are coming from mistakes committed when installing and tuning these components. The re-commissioning presented in this paper is based on both calculation and experimental data.
