Methods and systems for controlling a compressor cooling system

A controller comprising at least one processor and at least one memory, the controller connected to one or more temperature sensors, a first cooling valve, and a second cooling valve of a compressor, the at least one memory storing instructions that when executed by the at least one processor configures the controller to:

• control the compressor to compress refrigerant delivered to one or more refrigerant inlets;
• and
• execute a duty cycle logic loop comprising:
• receive compressor temperature readings from the one or more temperature sensors;
• and
• if a determination is that any of the compressor temperature readings are above an upper temperature threshold, perform the steps of:
• open the first cooling valve for a first period of time;
• close the first cooling valve and then open the second cooling valve for a second period of time;
• open both the first cooling valve and the second cooling valve for a third period of time;
• receive updated compressor temperature readings;
• and
• adjust one or more of the first period of time, the second period of time, and the third period of time based upon the updated compressor temperature readings.

A method for controlling a compressor implemented by a controller comprising at least one processor and at least one memory, the controller in communication with one or more temperature sensors to measure one or more locations on the compressor and a first cooling valve and a second cooling valve for controlling a flow of coolant to one or more locations on the compressor, the method comprises:

• executing a duty cycle logic loop comprising:
• receiving compressor temperature readings from the one or more temperature sensors;
• and
• if a determination is that any of the compressor temperature readings are above an upper temperature threshold, performing the steps of:
• opening the first cooling valve for a first period of time;
• closing the first cooling valve and opening the second cooling valve for a second period of time;
• opening both the first cooling valve and the second cooling valve for a third period of time;
• receiving updated compressor temperature readings;
• and
• adjusting one or more of the first period of time, the second period of time, and the third period of time based upon the updated compressor temperature readings.
