Abstract: A device and method for the detection of electrical discharge in an HVAC control box are disclosed. The device comprises an ultrasonic sensor(s) such as a MEMS-based sensor that detects the acoustic spectrum(s) generated within the HVAC control box, and a processing unit in communication with the ultrasonic sensor. The processing unit is configured to receive, from the ultrasonic sensor, the acoustic spectrum being detected within the HVAC control box and analyze the received acoustic spectrum to detect an electrical discharge within the HVAC control box.

Abstract: A system to detect movement of doors associated with an area of interest (AOI) is disclosed. The system comprises a pressure sensor positioned at a predefined position within the AOI, wherein the pressure sensor is operable to monitor air pressure within the AOI, and a processing device in communication with the pressure sensor. The processing device comprises one or more processors coupled to a memory storing instructions executable by the processors, and configured to monitor, using the pressure sensor, the air pressure within the AOI in real-time, detect and measure a change in the air pressure within the AOI based on the monitored air pressure, and detect opening or closing of one or more doors associated with the AOI based on the measured change in the air pressure within the AOI.

Abstract: A device for analyzing and discriminating faults in an HVAC system. The device comprises acoustic sensor(s) to monitor acoustic parameters associated with component(s) of the HVAC system, and electrical sensor(s) to monitor one or more electrical parameters associated with the component(s) of the HVAC system. The device comprises a processing unit in communication with the acoustic sensor(s) and the electrical sensor(s). The processing unit is configured to receive, from the acoustic sensor (s), the acoustic parameters being monitored within the HVAC system, receive, from the electrical sensor(s), the electrical parameters associated with the component(s) of the HVAC system, and analyze one or more of the received acoustic parameters, and the electrical parameters to detect and discriminate one or more faults in the component(s) of the HVAC system.

Abstract: A method and system for configuring a controller of a heating, ventilation, and air-conditioning (HVAC) equipment. The method can include receiving, with a near-field communication (NFC) module of the controller, configuration information for the HVAC equipment from a user device (e.g., equipped with near-field communications (NFC)), wherein the configuration information is used to configure the controller to control the HVAC equipment. The method can also include controlling the HVAC equipment based at least in part on the configuration information.
