Abstract
Systems and methods for a compressor system are provided for selectively operating the compressor system with reduced power consumption. An output demand level of the compressor system can be monitored over time to identify a demand profile. A pressure setpoint for the compressor system can be selectively adjusted based on the demand profile, including to selectively transition between an operational pressure setpoint for an active demand profile and a reduced pressure setpoint for an inactive demand profile.

1-20. (canceled)
A method of operating a compressor system, the method comprising:
- monitoring, with a control device, an output demand level of the compressor system over time to identify a demand profile;
- and
- with the control device, based on the demand profile, commanding a pressure setpoint for the compressor system to selectively transition between an operational pressure setpoint for an active demand profile, and a reduced pressure setpoint for an inactive demand profile;
- wherein the reduced pressure setpoint is substantially lower than the operational pressure setpoint.
A method of operating a compressor system, the method comprising:
- operating, with a control device, an electronic inlet valve that controls airflow to an inlet of a compressor, to selectively move the electronic inlet valve between different positions;
- determining, with the control device, a first duration of time over which a position of the electronic inlet valve is less than a first valve position threshold;
- and
- based upon the determined first duration of time being greater than a first time threshold, commanding, with the control device, a reduction in pressure in a tank from an operational pressure setpoint to a reduced pressure setpoint.
A compressor system comprising:
- a power source;
- a compressor operatively coupled to the power source;
- an inlet valve configured to selectively provide airflow to an inlet of the compressor;
- a tank in fluid communication with an outlet of the compressor;
- an outlet for flow of compressed air from the tank;
- and
- a control device configured to:
- monitor an output demand level of the compressor system over time to identify a demand profile;
- and
- based on the demand profile, command a pressure setpoint for the compressor system to selectively transition to an operational pressure setpoint when the demand profile is an active demand profile and to a reduced pressure setpoint when the demand profile is an inactive demand profile.
