A system and method for determining a fault condition in a compressor is provided. The current of a motor drive powering the compressor and the outdoor ambient temperature are measured and used to determine if a fault condition or a potential fault condition is present in the compressor. If a fault condition is determined to be present, the compressor can be shutdown to avoid damage to the compressor. If a potential fault condition is determined, remedial action can be taken to attempt to prevent the fault condition from occurring and shutting down the compressor.

System and method for detecting a fault condition in a compressor

A system and method for starting a compressor is provided. An amount of liquid refrigerant that is located in an oil sump of the compressor is determined. Using the determined amount of liquid refrigerant, a starting algorithm for the compressor is selected. The selected starting algorithm is configured to remove the determined amount of liquid refrigerant from the oil sump before the compressor reaches a preselected operating speed. The selected starting algorithm is then executed to start the compressor.

System and method for starting a compressor

A system to equalize pressure connected to a compressor for use in HVAC&R system is provided. The system includes a component in fluid communication between a high pressure side and an intermediate pressure side of the compressor. The component is configured to permit flow of refrigerant between the high pressure side and the intermediate pressure side at least when the compressor is not in operation.
