Title:
MULTISTAGE HVAC SYSTEM WITH DISCRETE DEVICE SELECTION PRIORITIZATION AND MODULATING DEVICE DEMAND CONTROL
Document Type and Number:
WIPO Patent Application WO/2019/108519
Kind Code:
A3
Abstract:
A controller for devices of a building control system that operate in parallel includes a capacity identifier configured to identify the desired capacity of heating or cooling for a building space. The controller further includes a combination finder configured to generate a list of combinations of devices that can be energized to provide the desired capacity. The controller further includes a combination filter configured to remove any combinations from the list that do not meet one or more requirements. The controller further includes a combination selector configured to select one of the combinations based on at least one of a runtime and a transition count. The controller further includes a make and break point selector configured to set one or more make and break points dependent on the desired capacity of heating or cooling according to the list of combinations and a capacity range of one or more modulating devices.
