Abstract: A refrigeration/air conditioning system includes a compressor (10) having a motor protector (54) which stops the compressor's motor when it senses an out of specification condition, A diagnostic system (100) of the refrigeration/air conditioning system monitors the status of the motor protector (54). The diagnostic system (100) includes logic circuitry (104) that diagnoses the type of problem the compressor (10) or the system is having based upon the running times and status of the motor in conjunction with the times and status of the tripped motor protector (54). The diagnostic system (100) also includes either a discharge pressure sensor (330) or a condenser temperature sensor (332), an ambient air sensor (334) and a voltage sensor (404). The sensors provide information to the diagnostic system (100) which enables it to determine where a system fault has occurred.

Abstract: A system includes a compressor and a controller. The controller operates the compressor in a flooded-start control mode. The flooded start control mode includes operating the compressor according to at least one cycle including a first time period during which the compressor is on, followed by a second time period during which the compressor is off. The controller determines at least one of the first time period, the second time period, and a number of cycles for the flooded-start control mode. At least one of the first time period, the second time period, and the number of cycles is based on received asset data corresponding to at least one of a type and a characteristic of at least one component of the refrigeration system. The controller operates the compressor in the flooded-start control mode after determining the first time period, the second time period, and the number of cycles.

Abstract: A climate-control system may include a variable-capacity compressor unit and a control module controlling the compressor unit. The compressor unit may be operable in a first capacity mode and in a second capacity mode that is higher than the first capacity mode. The control module may be configured to switch the compressor unit among a shutdown state, the first capacity mode and the second capacity mode based on a demand signal and outdoor-air-temperature

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 system and method for calculating parameters for a refrigeration system having a variable speed compressor is provided. A compressor is connected to a condenser and an evaporator. An evaporator sensor outputs an evaporator signal corresponding to at least one of an evaporator pressure and an evaporator temperature. An inverter drive modulates electric power delivered to the compressor to modulate a speed of the compressor. The control module is connected to the inverter drive and receives the evaporator signal, monitors electrical power data and compressor speed data from the inverter drive, and calculates at least one of a condenser temperature and a condenser pressure based on the evaporator signal, the electrical power data, and the compressor speed data.

Abstract: A system includes a compressor and a compressor motor functioning in a refrigeration circuit. A sensor produces a signal indicative of one of current and power drawn by the motor and a liquid-line temperature sensor provides a signal indicative of a temperature of liquid circulating within the refrigeration circuit. Processing circuitry processes the current or power signal to determine a condenser temperature of the refrigeration circuit and a subcooling value of the refrigeration circuit from the condenser temperature and the liquid-line temperature signal.
