Abstract
An exemplary compressor system includes a compressor having a fluid inlet and a fluid outlet. An isolation valve connects the fluid outlet of the compressor to a condenser. A controller is communicatively coupled to the isolation valve and the compressor. The controller includes a memory storing instructions configured to cause the controller to detect one of a surge event and a surge event precursor and restrict an opening in the isolation valve in response.
