Fan coil unit

Description

Fan coil units (FCU) are a common type of terminal equipment used to condition zones in residential and commercial buildings. The simulated system consists of a vertical four-pipe hydronic FCU controlling the temperature in a single zone. The FCU has a 3-speed fan, a damper for controlling the flow of outdoor air into the system, an air filter, a cooling coil and valve, a heating coil and valve, and various sensors for controlling and monitoring operation. The data set was created using HVACSIM+ developed by the US National Institute of Standards and Technology 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.
