Abstract: Systems and methods are disclosed that calibrate a defrost threshold used to determine when a heating, ventilating, and air conditioning (HVAC) system enters a defrost mode, and, more particularly, determine frost temperature differences used to determine the defrost threshold when the HVAC system is in a stable condition. A frost temperature difference is a difference between an outdoor ambient temperature and a refrigerant temperature. The HVAC system determines that it is in the stable condition by determining that a standard deviation of a current frost temperature difference from a previous frost temperature difference is below a standard deviation threshold. When the HVAC system is in the stable condition, the frost temperature differences are determined, and the defrost threshold is determined from the frost temperature differences.

Abstract: The present disclosure includes a heating, ventilation, and air conditioning (HVAC) system having a control system suitable to control operation of a device in the HVAC system. The control system may include a zone control panel that may control operation of the device using power-line communication. Accordingly, the zone control panel and the device may be both communicatively and electrically coupled via one or more power lines. To that end, the zone control panel may determine a primary address identifying the device and/or a secondary address indicating the one or more power lines electrically coupled to the device. Further, the zone control panel may communicate with and/or coordinate operation of the device by transmitting data messages to the device via the one or more power lines based on the primary address and/or the secondary address.

Abstract: A system for heating a building via refrigerant includes a coil temperature sensor, an ambient temperature sensor, and a controller. The controller includes a processing circuit configured to record a system operating parameter and a control step of a control process before performing a sacrificial defrost cycle. The processing circuit is configured to cause the system to perform the sacrificial defrost cycle and operate the system at predefined system operating parameters other than the recorded system operating parameters. The system is configured to cause the system to operate at the recorded system operating parameters and generate calibration data in response to the sacrificial defrost cycle ending. The processing circuit is configured to cause the control process to operate at the recorded control step and cause the system to perform a defrost cycle based on the calibration data, the coil temperature, and the ambient temperature.

Abstract: The present disclosure includes systems and methods for determining dimensions, shapes, and locations of rooms of a building using a mobile device for controlling heating, ventilation, and air conditioning (HVAC) provided to the rooms and building. A measuring device receives a shape of a room in the building and determines a dimension set of the room based on the shape of the room. The measuring device transmits the shape of the room and the dimension set to a mobile device that determines a layout of the building based on the shapes and the dimension sets corresponding to the rooms of the building. In this manner, the systems and methods provide the layout of the building more efficiently, resulting in an improved HVAC system installation and operation process.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) system includes a control system, a storage of the control system that stores instructions and a set of operating conditions of the HVAC system, and processor circuitry of the control system. One or more operating conditions of the set of operating conditions is associated with a respective operational sound level, and the processor circuitry is configured to execute the instructions to receive a threshold sound level and operate the HVAC system according to an operating condition of the set of operating conditions based on an operational sound level of the operating condition being less than or equal to the threshold sound level.

Abstract: A control system for a heating, ventilation, and/or air conditioning (HVAC) system includes a sensor configured to detect a concentration of refrigerant in air. The control system also includes a controller configured to receive feedback from the sensor indicative of the concentration of refrigerant in air, determine that the concentration of refrigerant in air is less than a threshold value, and determine that the HVAC system is in an operating mode. The controller is configured to operate a blower of the HVAC system for a predetermined time period based on the determinations that the concentration of refrigerant in air is less than the threshold value and that the HVAC system is in the operating mode.

Abstract: A heating, ventilation, and air conditioning (HVAC) system may include a HVAC unit that may control air flow, a first control system that may directly control operation of equipment in the HVAC unit, and a second control system communicatively coupled to the first control system. The second control system may be located in a different zone of a building as compared to the first control system, such that the second control system may receive a request to adjust the air flow output by the HVAC unit and send a command to the first control system based on the request. The command may cause the first control system to adjust the operation of the equipment in the HVAC unit to cause the air flow output by the HVAC unit to be adjusted according to the request.
