Abstract: A control for a refrigeration system serviced by a special pulse width modulated compressor (30) coupled to a condenser (32)and evaporator (42). The system can be of the distributed type wherein the condenser (32) and compressor (30) may be coupled to service a group of adjacent refrigeration cases, wherein each case would have its own evaporator (42). A controller (52) is coupled to a load sensor (58) for producing a variable duty cycle control signal (54) in which the duty cycle is a function of demand for cooling. Moreover, fuzzy logic technique may be utilized in order to provide self adaptive tuning control for the system.

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: l: \tId\Intrwovn\NRPortbl\DCC\TLD\5041400_l doc-4 04/2013 A compressor includes a shell, a compression mechanism, a motor, a data module, and a compressor controller. The data module includes a processor and a 5 memory. The compressor controller includes a processor and a memory. The data module receives sensed data, stores sensed data in the memory, and communicates sensed data to the compressor controller. The compressor controller controls a capacity of the compressor based on the sensed data and is operable 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.
