Abstract:
A building management system includes building equipment, a sensor, and a saturation detector. The building equipment is configured to operate at an operating capacity to drive a variable state or condition of a building zone toward a setpoint. The operating capacity and the setpoint vary over time. The sensor is in the building zone and is configured to provide a zone measurement of the variable state or condition of the building zone. The saturation detector is configured to determine whether the operating capacity is in a non-transient region for a threshold amount of a time period upon determining that an error for the building zone exists for the time period, and, in response to a determination that the operating capacity is in the non-transient region for at least the threshold amount of the time period, indicate the time period as a saturation period.

Claim (Index 15):
A method for saturation detection in an HVAC system, comprising:\n operating HVAC equipment at a measurable operating capacity to heat or cool a building zone to approach a setpoint temperature; measuring air temperature in the building zone; changing the setpoint temperature a plurality of times over a time span; for each of a plurality of time steps in the time span, aggregating data that includes an operating capacity, a setpoint temperature, and an air temperature; defining a transient region of operating capacities corresponding to a non-saturated status and a non-transient region as outside of the transient region; and for each of a plurality of time periods bound by sequential changes in setpoint temperatures,\n calculating an error term for the time period based on the air temperatures and the setpoint temperature for the time period; \n calculating an error threshold based on the setpoint temperature for the time period and a preceding setpoint temperature; \n determining whether the error term is greater than the error threshold; \n in response to a determination that the error term is greater than the error threshold, determining whether the operating capacity is in the non-transient region for a threshold amount of the time period; and \n in response to a determination that the operating capacity is in the non-transient region for the threshold amount of the time period, indicating the time period as a saturation period.
