Abstract:
Apparatus and methods for Fault Detection Diagnostics (FDD) for a Heating, Ventilating, Air Conditioning (HVAC) system with an economizer to detect: 1) air temperature or relative humidity sensors failed/faulted, 2) dampers not modulating, 3) excessive outdoor air, 4) economizing when should not, 5) not economizing when should and 6) inadequate outdoor air. Economizer damper position is measured using at least one inertial Micro-Electro-Mechanical System (MEMS) device: 1) magnetometer, 2) accelerometer, 3) IMU and 4) rotatiometer. The magnetometer detects damper position using a small permanent-magnet attached to a movable damper and a MEMS device attached to the economizer frame. The accelerometer and IMU detect damper position using a MEMS device attached to the damper, and the ratiometer detects angular damper position. The methods determine whether or not the HVAC economizer, sensors, actuator and outdoor air dampers are functioning properly. If economizer faults are detected, then the method provides electronically-transmitted fault signals.

Claim (Index 10):
The apparatus of  claim 1 , wherein the damper position inertial sensors are selected from the group consisting of:\n a magnetometer Micro-Electro-Mechanical Systems (MEMS) device attached to an economizer frame and a fixed permeant magnet attached to a movable damper wherein the damper moves from one position (i.e., closed) to another position (i.e., open) and the magnetometer detects the magnitude and direction of the 3-dimensional permanent magnetic field (Gauss) from the magnet and from this information the magnetometer provides the damper position with respect to at least one reference or rotational position within a 3-dimensional coordinate system, an accelerometer MEMS device attached to a movable damper wherein the damper moves from one position (i.e., closed) to another position (i.e., open) and the gravitational vector shifts from at least one location of a 3-dimensional coordinate system to another location and the accelerometer detects this change and provides the damper position with respect to at least one reference or rotational position within a 3-dimensional coordinate system, an IMU MEMS device attached to a movable damper wherein the damper moves from one position (i.e., closed) to another position (i.e., open) and the IMU uses miniature accelerometers and gyroscopes to detect angular motion from at least one dimension of the 3-dimensional location to another location and the IMU detects this change and provides the damper position with respect to at least one reference or rotational position within a 3-dimensional coordinate system, and a rotatiometer MEMS device attached to at least one location selected from the group consisting of: the economizer, the economizer damper, and the economizer actuator; and wherein the rotatiometer detects rotation of the damper or actuator from one rotational or angular position to another rotational or angular position with respect to at least one reference rotational or angular position.
