Chiller plant


The simulated chiller plant serves a 12-story building with individual floors having a dedicated AHU with a chilled water cooling coil. The plant consists of a primary loop with three chillers for producing chilled water , a secondary loop for delivering chilled water to the AHUs, and a condenser water loop with cooling towers for rejecting heat to the ambient. Sensors, pumps, and valves are used to control water flow through the plant. 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 data set, including system type and diagram, control sequence, description of data points, and the faulty and fault-free scenarios represented in each CSV file.
