    Abstract: An apparatus includes a voltage sensor, a current sensor, and a controller. The voltage sensor measures voltage values of alternating current power supplied to a capacitor. The capacitor is electrically coupled to a compressor. The current sensor measures current values of the alternating current power. The controller is configured to receive the voltage values and the current values. The controller is configured to determine a first power factor value based on at least one of the voltage values and at least one of the current values. The controller is configured to selectively detect a first capacitor fault in response to concurrent determination that (i) the first power factor value is less than a first power factor threshold and (ii) a first current value of the current values is greater than a first current threshold. The first capacitor fault indicates that a capacitance of the capacitor has degraded.

    Abstract: A heating, ventilation, and air conditioning (HVAC) system of a building includes a refrigerant loop. A monitoring system for the HVAC system includes a monitoring device installed at the building. The monitoring device is configured to measure a first temperature of refrigerant in a refrigerant line located between a filter-drier of the refrigerant loop and an expansion valve of the refrigerant loop. The monitoring system includes a monitoring server, located remotely from the building. The monitoring server is configured to receive the first temperature and, in response to the first temperature being less than a threshold, generate a refrigerant line restriction advisory. The monitoring server is configured to, in response to the refrigerant line restriction advisory, selectively generate an alert for transmission to at least one of a customer and an HVAC contractor.

    Abstract: A system and method for a heating, ventilation, and air conditioning (HVAC) system of a building is provided. A monitoring device installed at the building is configured to measure a current supplied to the HVAC system and transmit current data based on the measured current. The monitoring system includes a monitoring server, located remotely from the building, configured to receive the transmitted current data and, based on the received current data, determine an average motor current over a predetermined time period and determine whether a failure has occurred in an air filter of the HVAC system based on a comparison of the average motor current with a predetermined threshold. The monitoring server generates a notification based on the comparison indicating that the failure has occurred in the air filter.

    Abstract: A heat-pump circuit may include an indoor heat exchanger, an outdoor heat exchanger, a compressor adapted to circulate a working fluid between the indoor and outdoor heat exchangers, and an expansion device disposed between the indoor and outdoor heat exchangers. A monitor for the heat-pump system may include a return-air temperature sensor, a supply-air temperature sensor, and a processor. The return-air temperature sensor may be adapted to measure a first air temperature of air upstream of the indoor heat exchanger. The supply-air temperature sensor may be adapted to measure a second air temperature of air downstream of the indoor heat exchanger. The processor may be in communication with the return-air temperature sensor and the supply-air temperature sensor. The processor may be programmed to determine a working-fluid-charge condition of the heat-pump system based on the first and second air temperatures.

    Abstract: Systems and methods that detect a loss of charge associated with a climate controlled environment are described in the present disclosure. In various embodiments, a controller receives operating condition parameters associated with a climate-controlled environment. The controller determines whether a compressor is operating in a first mode of operation or a second mode of operation. The controller applies a first model to the operating condition parameters when the compressor is operating in the first mode of operation to represent a loss of charge associated with the climate-controlled environment and applies a second model to the operating condition parameters when the compressor is operating in the second mode of operation to represent the loss of charge associated with the climate-controlled environment.
