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.

Abstract: In one embodiment of the present disclosure, a heating, ventilating, and air conditioning (HVAC) system includes a refrigerant circuit configured to flow a refrigerant. The refrigerant circuit includes a compressor configured to compress the refrigerant, a condenser configured to receive the refrigerant from the compressor and to condense the refrigerant, a valve configured to receive a first portion of the refrigerant from the condenser and to decrease a pressure of the first portion of the refrigerant, and an evaporator configured to receive the first portion of the refrigerant from the condenser and configured to evaporate the first portion of the refrigerant. The refrigerant circuit also includes a refrigerant sub-circuit configured to receive a second portion of the refrigerant from the condenser and to convert thermal energy of the second portion of the refrigerant to electrical energy.

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 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: A tangible, non-transitory, machine-readable medium includes instructions that, when executed by a processor, cause the processor to determine an active operating condition of the heating, ventilation, and/or air conditioning (HVAC) system based on the active operating data related to the HVAC system, retrieve an existing service log having a maintenance procedure corresponding to the active operating condition of the HVAC system, and record an entry service log. The entry service log includes the active operating data, the active operating condition, and an updated version of the maintenance procedure corresponding to the active operating condition.

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.
