Abstract:
A method includes initiating, by a controller of a heating, ventilation, and air conditioning (“HVAC”) system, a filter calibration procedure, curve fitting a first line based on a plurality of static pressure measurements and corresponding flowrates of air, and generating a second line based on the first line. The method further includes determining a first static pressure measurement sensed by at least one sensor in response to determining that a first flowrate of air has been moved by the at least one blower and comparing the first static pressure value to a predicted static pressure value of the second line, the predicted static pressure value corresponding to the first flowrate of air. The method further includes determining that an air filter of the HVAC system has no more usable life in response to determining that the first static pressure value is greater than the predicted static pressure value.

Claim (Index 18):
At least one controller of a heating, ventilation, and air conditioning (\u201cHVAC\u201d) system, the at least one controller operable to:\n initiate a filter calibration procedure in response to detecting installation of an air filter within the HVAC system, wherein:\n the air filter is configured to entrap airborne pollutants; and \n the filter calibration procedure comprises measuring a static pressure of the HVAC system at a plurality of predetermined points, each predetermined point being a specified flowrate of air moved by at least one blower of the HVAC system, the static pressure measured by at least one sensor of the HVAC system; \n curve fit, by the controller, a first line based on the static pressure measurements and the corresponding flowrates of air, the first line indicating values of static pressure and corresponding flowrates of air of a clean filter; generate a second line based on the first fine, the second line indicating predicted values of static pressure and corresponding flowrates of air of a dirty filter; in response to determining that a first flowrate of air has been moved by the at least one blower, determine a first static pressure measurement of the HVAC system; compare the first static pressure value to a predicted static pressure measurement of the second line, the predicted static pressure value corresponding to the first flowrate of air; and in response to determining that the first static pressure measurement is greater than the predicted static pressure value, determine that an air filter of the HVAC system has no more usable life.
