    Abstract: A sound level control system for a heating, ventilation, and air conditioning (HVAC) system is provided. The sound level control system comprises an outdoor unit with a compressor, an outdoor fan, and an outdoor controller and a communication device located at a predefined distance from the outdoor unit. The communication device measures sound levels in response to operating the outdoor unit. The outdoor controller is configured to receive a first noise level limit for a predefined time period, receive an instruction related to selective control of the outdoor unit, selectively control both of the compressor to rotate at a first compressor speed and the outdoor fan to rotate at a first fan speed based on the noise level limit for the predefined time period, and receive information related to whether a sound pressure level at a predefined location exceeds the first noise level limit for the predefined time period.

    Abstract: Devices, systems, and methods are disclosed for reducing leakage current in compressors, such as for HVAC systems. Several embodiments include a leakage current suppressor configured to reduce passage of electrical current into the housing of a compressor via a conductive pathway between an electrical conductor and the housing. For instance, the leakage current suppressor may sufficiently reduce the passage of electrical current into the housing of a compressor to prevent tripping a GFCI. In many embodiments, the conductive pathway may be formed, at least in part, by a liquid refrigerant in the compressor housing.

    Abstract: Examples of the present disclosure relate to systems and methods for operating a climate control system on a microgrid utilizing renewable sources of power including solar panels and wind turbines. In general, this disclosure focuses on utilizing a range of stepped or discrete demand responses for the climate control system to adjust power consumption levels in response to variable levels of power input associated with renewable power sources attached to the microgrid. These stepped or discrete demand responses of the climate control system may allow the microgrid to react to linear, continuous, or non-discrete fluctuations in the input power while reducing the likelihood of damage to the climate control system. Some examples may also allow the climate control system to more consistently maintain comfort settings of conditioned spaces. Some examples utilize a direct current (DC) microgrid and climate control system.
