    Abstract: Systems and methods for determining the health of a compressor are disclosed. In one embodiment, a prognostic-diagnostic unit (PDU) compares expected compressor power consumption, based on current operating conditions of the HVAC system, to actual compressor power consumption. If the actual power consumption is within a predefined range of the expected power consumption under current operational conditions, the HVAC system is determined to be operating properly. If the actual power consumption deviates from the expected power consumption, a fault is indicated. An appropriate action is taken, such as displaying a fault alert, transmitting a fault message to another device, and storing information relating to the fault for later retrieval to assist troubleshooting.

    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 translation: 公开了用于确定压缩机健康状况的系统和方法。 在一个实施例中，预测诊断单元（PDU）基于HVAC系统的当前操作条件将预期的压缩机功率消耗与实际的压缩机功率消耗进行比较。 如果实际功耗在当前操作条件下的预期功率消耗的预定范围内，则HVAC系统被确定为正常工作。 如果实际功耗偏离预期功耗，则会显示故障。 采取适当的措施，例如显示故障警报，向其他设备发送故障消息，并存储与故障相关的信息以供以后检索以辅助故障排除。
