Abstract
System and methods for automatic detection and clustering of variable air volume units in a building management system are disclosed. In one aspect, a method includes receiving one or more of variable air volume unit (VAV) data and an air handling unit (AHU) data from one or more data sources, determining one or more VAVs as a suspect VAV based on the VAV data and the AHU data, and removing the suspect VAV to determine a duct static pressure setpoint for an AHU.
Claims20
A building management system comprising:
- one or more memory devices configured to store instructions thereon that, when executed by one or more processors, cause the one or more processors to:
- receive one or more of variable air volume unit (VAV) data or air handling unit (AHU) data from one or more data sources;
- determine that one or more VAVs qualify as a suspect VAV in response to one or more conditions being satisfied by at least one of (i) the VAV data or (ii) the VAV data and the AHU data;
- classify the suspect VAV as a first type of suspect VAV in response to a first set of the one or more conditions being satisfied;
- classify the suspect VAV as a second type of suspect VAV in response to a second set of the one or more conditions being satisfied;
- in response to the suspect VAV being classified as the first type of suspect VAV, remove a portion of the VAV data associated with the suspect VAV from a calculation of a duct static pressure setpoint (DPT-SP) for an AHU and operate building equipment to affect an airflow provided to one or more building zones using an adjusted value of the DPT-SP after removing the portion of the VAV data associated with the suspect VAV from the calculation of the DPT-SP;
- and
- in response to the suspect VAV being classified as the second type of suspect VAV, increase or decrease the value of the DPT-SP and operate the building equipment to affect the airflow provided to the one or more building zones using the increased or decreased value of the DPT-SP.

A method of monitoring and controlling building equipment, the method comprising:
- receiving one or more of variable air volume unit (VAV) data or air handling unit (AHU) data from one or more data sources;
- determining that one or more VAVs qualifies as a suspect VAV in response to one or more conditions being satisfied by at least one of (i) the VAV data or (ii) the VAV data and the AHU data;
- classifying the suspect VAV as a first type of suspect VAV in response to a first set of the one or more conditions being satisfied;
- classifying the suspect VAV as a second type of suspect VAV in response to a second set of the one or more conditions being satisfied;
- in response to the suspect VAV being classified as the first type of suspect VAV, removing a portion of the VAV data associated with the suspect VAV from a calculation of a duct static pressure setpoint (DPT-SP) for an AHU and operating building equipment to affect an airflow provided to one or more building zones using an adjusted value of the DPT-SP after removing the portion of the VAV data associated with the suspect VAV from the calculation of the DPT-SP;
- and
- in response to the suspect VAV being classified as the second type of suspect VAV, increasing or decreasing the value of the DPT-SP and operating the building equipment to affect the airflow provided to the one or more building zones using the increased or decreased value of the DPT-SP.

A building management system comprising:
- one or more variable air volume units (VAVs) configured to provide air flow into a building;
- an air handling unit (AHU) configured to provide the air flow to the one or more VAVs;
- and
- one or more memory devices configured to store instructions thereon that, when executed by one or more processors, cause the one or more processors to:
- receive VAV data from the one or more of VAVs or AHU data from the AHU;
- determine that one or more VAVs as a suspect VAV in response to one or more conditions being satisfied by at least one of (i) the VAV data or (ii) the VAV data and the AHU data;
- classify the suspect VAV as a first type of suspect VAV in response to a first set of the one or more conditions being satisfied;
- classify the suspect VAV as a second type of suspect VAV in response to a second set of the one or more conditions being satisfied
- in response to the suspect VAV being classified as the first type of suspect VAV, remove a portion of the VAV data associated with the suspect VAV from a calculation of a duet static pressure setpoint for the AHU and operate building equipment to affect an airflow provided to one or more building zones using an adjusted value of the duct static pressure setpoint after removing the portion of the VAV data associated with the suspect VAV from the calculation of the duct static pressure setpoint;
- and
- in response to the suspect VAV being classified as the second type of suspect VAV, increase or decrease the value of the DPT-SP and operate the building equipment to affect the airflow provided to the one or more building zones using the increased or decreased value of the DPT-SP.
