CONTROL METHODS FOR CALIBRATING MOTOR SPEED IN AN AIR TREATMENT SYSTEM
First Claim
1. A method for calibrating motor speed for a blower motor in an air treatment system, comprising the steps of:
- collecting a plurality of readings indicative of the motor speed over a period of time;
computing a comparison value as a function of the collected readings;
comparing the comparison value to a predetermined acceptable range; and
adjusting the speed of the motor if the comparison value falls outside the predetermined acceptable range.

Abstract
A control system and associated methods for an air treatment system. In one aspect, the present invention provides a control system and method for controlling blower speed as a function of separately determined smoke and dust concentrations. In one embodiment, the control system and method provides a variable delayed between changes in motor speed to address undesirable rapid changes between speeds. In another aspect, the present invention provides a system and method for calibrating a sensor to provide more uniform operation over time. In yet another aspect, the present invention provide a system and method for calibrating motor speed to provide more consistent and uniform motor speed over time. The present invention also provides a system and method for tracking filter life by as a function of time, motor speed and/or a sensed variable, such as particulate concentration in the environment.

14. A method for calibrating motor speed for blower motor in an air treatment system, comprising the steps of:
-
providing a blower motor capable of operating at a plurality of different motor speed settings; predetermining an acceptable range of blower motor speeds for each of the different motor speed settings; taking a plurality of readings at predetermined intervals from a sensor indicative of motor speed; computing a comparison value as a function of the readings, the comparison value being indicative of average motor speed over a period of time; comparing the comparison value to the predetermined acceptable range for the corresponding motor speed setting; adjusting the actual speed of the motor if the comparison value falls outside the predetermined acceptable range by a predetermined amount; and repeating said collecting, computing, comparing and adjusting steps until the comparison value falls within the predetermined acceptable range. - View Dependent Claims (15, 16, 17)
