Single-duct AHU

Description

The simulated system consists of a single-duct air handling unit (SD-AHU) providing conditioned air to five VAV terminal units, each serving a single zone (four perimeter and one interior) on the middle floor of a three-story building.. The SD-AHU has a chilled water cooling coil, and variable speed supply and return fans, and delivers air at a constant temperature and static pressure to the terminal units. Individual terminal units control the volume of air entering a zone and use hydronic reheat when necessary to satisfy the temperature setpoint in a zone. The data set was created using EnergyPlus-Modelica co-simulation and comprises a collection of comma separated value (CSV) files. Each CSV file represents either a fault-free case or a faulty case representing a single fault type at a specific severity level. A separate data inventory file documents key information for the dataset, including system type and diagram, control sequence, description of data points, and the faulty and fault-free scenarios represented in each CSV file.
