Abstract: A heating, ventilation, and/or air conditioning (HVAC) system includes a compressor, a fan, an inverter configured to drive operation of the compressor, and a controller communicatively coupled to the fan and the inverter. The controller includes a tangible, non-transitory, computer-readable medium with computer-executable instructions that, when executed by processor circuitry, are configured to cause the processor circuitry to determine an operating parameter of the fan in response to an interruption in receiving communication signals from the inverter and operate the fan based on the operating parameter during the interruption.

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/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 residential HVAC system includes, a compressor, and an outdoor unit controller in communication with the compressor. The outdoor unit controller is configured to receive an indoor ambient temperature and a temperature set point. The outdoor unit controller is further configured to determine an outdoor ambient temperature, and to determine an operating value for the compressor based on a percentage of a delta between a minimum operating value of the compressor and a maximum operating value of the compressor, plus the minimum operating value. The minimum operating value and the maximum operating value are based on the determined outdoor ambient temperature. The percentage of the delta is based on a predefined temperature differential multiplier and one or more time dependent multipliers. The outdoor unit controller is further configured to modify the current operating value of the compressor with the determined operating value.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) system includes a sensor configured to detect an operating parameter of the HVAC system, a processor, and a memory having instructions executable by the processor to cause the processor, during a normal operation mode of the HVAC system, to iteratively receive feedback from the sensor indicative of a value of the operating parameter, compare the value with reference data, and determine a refrigerant charge level of the HVAC system based on the value and the reference data.

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: 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: A heating, ventilation, and air conditioning (HVAC) system includes a controller associated with a residence. The controller is configured to determine an expected value range for an operating parameter of a component of the HVAC system. Additionally, the controller is configured to receive a signal from a sensor indicative of a current value of the operating parameter of the component and determine if the current value of the operating parameter is outside the expected value range. Based on the determination that the current value is outside the expected value range, the controller is additionally configured to initiate a diagnostic mode of the controller. In the diagnostic mode, the controller is configured to collect diagnostic data associated with the HVAC system.
