Abstract
A heating, ventilation, and/or air conditioning (HVAC) system includes processing circuitry configured to receive a plurality of air flow rates, in which each air flow rate of the plurality of air flow rates is associated with a zone of a plurality of zones of the HVAC system, determine a sum of the plurality of air flow rates is outside of a threshold range around a total output air flow rate, and, in response to determining the sum of the plurality of air flow rates is outside of the threshold range around the total output air flow rate, adjust an air flow rate of the plurality of air flow rates based on a comparison between the sum of the plurality of air flow rates and the total output air flow rate.

A heating, ventilation, and/or air conditioning (HVAC) system, comprising:
- processing circuitry configured to:
- receive a plurality of air flow rates, wherein each air flow rate of the plurality of air flow rates is associated with a respective zone of a plurality of zones of the HVAC system;
- determine a sum of the plurality of air flow rates is outside of a threshold range around a total output air flow rate of air flow to be distributed to the plurality of zones;
- in response to determining the sum of the plurality of air flow rates is outside of the threshold range around the total output air flow rate, adjust an air flow rate of the plurality of air flow rates based on a comparison between the sum of the plurality of air flow rates and the total output air flow rate;
- and
- operate the HVAC system to deliver air to the plurality of zones based on the plurality of air flow rates and based on adjustment of the air flow rate of the plurality of air flow rates.
A tangible, non-transitory, computer-readable medium with computer-executable instructions that, when executed by processing circuitry, cause the processing circuitry to:
- receive a plurality of indicated air flow rates, wherein each indicated air flow rate of the plurality of indicated air flow rates is associated with a respective zone of a plurality of zones of a heating, ventilation, and/or air conditioning (HVAC) system;
- determine a sum of the plurality of indicated air flow rates is outside of a threshold range around a total output air flow rate of the HVAC system, wherein the total output air flow rate is associated with total air flow to be distributed to the plurality of zones;
- adjust the plurality of indicated air flow rates to establish a plurality of adjusted air flow rates in response to the determination that the sum of the plurality of indicated air flow rates is outside of the threshold range around the total output air flow rate;
- and
- operate the HVAC system to deliver respective air flows to the plurality of zones based on the plurality of adjusted air flow rates.
A heating, ventilation, and/or air conditioning (HVAC) system, comprising:
- a blower configured to output an air flow at an output air flow rate;
- ductwork fluidly coupling the blower to a plurality of zones of the HVAC system, wherein the ductwork is configured to distribute the air flow output at the output air flow rate by the blower to the plurality of zones;
- and
- a control system configured to:
- receive a plurality of indicated air flow rates, wherein each indicated air flow rate of the plurality of indicated air flow rates is associated with a respective zone of the plurality of zones of the HVAC system;
- determine a sum of the plurality of indicated air flow rates is outside of a threshold range around the output air flow rate;
- adjust the plurality of indicated air flow rates to establish a plurality of adjusted air flow rates in response to determining the sum of the plurality of indicated air flow rates is outside of the threshold range around the output air flow rate;
- and
- operate the HVAC system to enable the air flow output by the blower to be supplied to each zone of the plurality of zones based on the plurality of adjusted air flow rates.
