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.
Claims20
A compressor system, comprising:
- a power source;
- a compressor operatively coupled to the power source;
- an inlet valve 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:
- determine a duration of time over which an output demand level of the compressor system is below a first demand threshold;
- and
- based upon the determined duration being greater than a time threshold, command a reduction in pressure in the tank from an operational pressure setpoint to a reduced pressure setpoint.
A method of operating a compressor system that includes a power source, a compressor operatively coupled to the power source, an inlet valve to selectively provide airflow to an inlet of the compressor, a tank in fluid communication with an outlet of the compressor, and an outlet for flow of compressed air from the tank, the method comprising:
- determining, with a control device, a duration of time over which an output demand level of the compressor system is below a first demand threshold;
- and
- with the control device, based on the determined duration being greater than a time threshold, commanding a reduction in pressure in the 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 electronic inlet valve 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:
- operate the electronic inlet valve to selectively move the electronic inlet valve between different positions;
- determine 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 predetermined time threshold, command a reduction in pressure in the tank from an operational pressure setpoint to a reduced pressure setpoint.
