Abstract: Techniques are disclosed for early detection of fan failure in a computing device, such as a server. A management device located in the computing device or remote from the computing device can receive information about the fan duty and use the fan duty information to determine a safe fan speed below which future or imminent fan failure can be inferred. The management device can receive the current speed of the fan and compare it with the safe fan speed to determine if the fan is likely to fail, in which case the management device can direct the computing device to perform mitigation action and/or a maintenance warning can be sent. The maintenance warning can result in replacement of the failing or soon-to-fail fan.

Abstract: A method and apparatus for a visual local controller (VLC) for a variable speed motor (VS Motor) or other controlled device in an HVACR system to display the output in engineering units instead of the traditional percent of motor output or similar output, and to limit the output to a range between a high limit and a low limit, is disclosed. An engineering units display allows end users to directly see output as performed by the connected HVACR equipment. In place of zero to one-hundred percent output, the user may see torque, CFM, actual control voltage or other engineering units associated with the controlled HVACR equipment. Limiting the output allows the output to be constrained between high and low output limits to keep the connected device operating within a safe range for the HVACR equipment.

Abstract: A fan system includes a motor, a rotatable hub, and a plurality of fan blades. The motor is coupled with the hub by a hollow drive shaft, such that the drive system of the fan system is gearless. The motor is controlled by a PFC-based control module, which is in communication with sensors that are configured to sense parameters associated with operation of the fan system. The control module is configured to react in certain ways to certain conditions detected by the sensors, such that the fan system uses feedback-based control algorithms. A remote control panel is in communication with the control module. The remote control panel is operable to display fault conditions detected by the sensors. Blade retainers prevent fan blades from falling when a fan blade breaks free from the hub. Pins prevent the hub from falling when the hub breaks free from the rotor.

Abstract: Systems and methods are provided for maintaining an air conditioning system. A system can include one or more sensors positioned inside of the air conditioning system configured to transmit current sensor data to a remote location. A data repository contains historic sensor data and corresponding air conditioning system status data. A neural network is trained using the historic sensor data and the corresponding air conditioning system status data to predict a future air conditioning system status based on the transmitted current sensor data. A server computer system is configured to predict the future air conditioning system status based on the current sensor data using the neural network, and a graphical user interface is configured to display the predicted future air conditioning system status to a remote client. The current sensor data is stored in the data repository and the neural network is further trained based on the current sensor data.
