Buildings.Templates.ZoneEquipment.Components.Controls

Information

All control blocks that form the control sequence of a system are instantiated into one single class, a so-called control section. This package contains such control sections.

Buildings.Templates.ZoneEquipment.Components.Controls.G36VAVBoxCoolingOnly

Guideline 36 controller for VAV terminal unit cooling only

Buildings.Templates.ZoneEquipment.Components.Controls.G36VAVBoxCoolingOnly

Information

Description

This is an implementation of the control sequence specified in ASHRAE (2021) for cooling-only VAV terminal units. It contains the following components.

Buildings.Controls.OBC.ASHRAE.G36.TerminalUnits.CoolingOnly.Controller: Main controller for the terminal unit
Buildings.Controls.OBC.ASHRAE.G36.ThermalZones.Setpoints: Computation of the zone temperature setpoints
Buildings.Controls.OBC.ASHRAE.G36.ZoneGroups.ZoneStatus: Computation of the zone warm-up and cooldown time
