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: The present disclosure relates to a zoning system for climate control including a controller configured to operate the zoning system to supply conditioned air to a first zone of a plurality of zones through a first supply air damper to thermally charge the first zone. The controller is also configured to close the first supply air damper of the first zone and open a second supply air damper of a second zone of the plurality of zones after the first zone is thermally charged. The controller is further configured to operate the zoning system to draw the conditioned air from the first zone and supply the conditioned air to the second zone through the second supply air damper.

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 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: The present disclosure presents techniques for improving operational efficiency of climate control systems. A climate control system may include climate control equipment, a sensor that measures temperature in a building, and a control system that controls operation of the equipment using a first temperature schedule, which associates each time step with a temperature setpoint, when the building is occupied. When not occupied, the control system determines an expected return time based on historical occupancy data associated with the building, determines the temperature setpoint associated with the expected return time, determines candidate schedules each expected to result in the inside air temperature meeting the temperature setpoint, determines efficiency metrics each associated with one of the candidates based on historical performance data resulting from previous operation of the climate control system, and controls operation of the equipment based on a second temperature schedule selected from the candidates based on associated efficiency metrics.
