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: System and methods are provided and include a compressor operable in a refrigeration circuit, a first sensor detecting high-side data indicative of a high-side operating condition of a high-pressure side of the refrigeration circuit, a second sensor detecting low-side data indicative of a low-side operating condition of a low-pressure side of the refrigeration circuit, and processing circuitry. The processing circuitry receives the high-side data and the low-side data, determines a high-side fault, a low-side fault, a severe high-side fault, or a severe low-side fault based on the high-side data and the low-side data, operates the compressor in a limp-along mode by restricting power to the compressor or reducing a capacity of the compressor in response to determining at least one of the high-side fault and the low-side fault, and shuts down the compressor in response to determining at least one of the severe high-side fault and the severe low-side fault.

Abstract: A system and method for a compressor includes a compressor connected to a condenser, a discharge line temperature sensor that outputs a discharge line temperature signal corresponding to a discharge line temperature of refrigerant leaving the compressor, and a control module connected to the discharge line temperature sensor. The control module determines a saturated condenser temperature, calculates a discharge superheat temperature based on the saturated condenser temperature and the discharge line temperature, and monitors a flood back condition of the compressor by comparing the discharge superheat temperature with a predetermined threshold. The control module increases a speed of the compressor when the discharge superheat temperature is less than or equal to the predetermined threshold.
