Abstract: A compressor is provided and may include a shell, a compression mechanism, a motor, and a diagnostic system that determines a system condition. The diagnostic system may include a processor and a memory and may predict a severity level of the system condition based on at least one of a sequence of historical-fault events and a combination of the types of the historical-fault events.

Abstract: A scroll type machine incorporates a unique system for monitoring the status of a valve which is used to control the capacity of the compressor. The valve functions to open and close a fluid passage between two areas of the compressor for capacity modulation. By monitoring the temperature of the fluid after the valve, it can be determined whether or not the valve is functioning. If the temperature fluctuates, the valve is functioning. If the temperature is constant, the valve is not operating properly. Another embodiment monitors the pressure within the fluid line controlled by the valve.

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 compressor includes a shell, a compression mechanism, a motor, a data m odule, and a compressor controller. The data module includes a processor and a memory. The compressor controller includes a processor and a memory. The data module receives sensed data, stores sensed data in the memory, and comm unicates sensed data to the compressor controller. The compressor controller controls a capacity of the compressor based on the sensed data and is opera ble to communicate with a system controller of a refrigeration system.

Abstract: A system and method includes a power supply that generates an alternating current power for powering a compressor with a capacitor, a voltage sensor that measures voltage values based on the alternating current power, a current sensor that measures current values based on the alternating current power, and a controller. The controller communicates with the voltage sensor and the current sensor, determines a power factor value based on at least one of the voltage values and at least one of the current values, and determines a fault in the capacitor based on the power factor and at least one of the current values.
