Abstract
A fluid compressor system can include a compressor, a power source operably connected to the compressor to power the compressor, and a control system. The control system includes one or more control devices configured to determine a system temperature of the fluid compressor system, determine a target operating pressure based on the system temperature, and selectively operate the fluid compressor system in a water removal mode, including controlling a system pressure of the fluid compressor system based on the target operating pressure to vaporize liquid within the compressor system.
Claims20
A fluid compressor system comprising:
- a compressor having a compressor inlet and a compressor outlet, the compressor being configured to receive fluid at the compressor inlet and supply compressed fluid at the compressor outlet;
- a power source operably connected to the compressor to power the compressor to supply the compressed fluid;
- a separator tank in fluid communication with the compressor outlet to receive the compressed fluid and separate entrained liquid from the compressed fluid;
- and
- a control system, including one or more control devices configured to:
- determine a system temperature of the fluid compressor system;
- determine a target operating pressure based on the system temperature;
- and
- selectively operate the fluid compressor system in a water removal mode, including controlling a system pressure of the fluid compressor system based on the target operating pressure to vaporize at least part of the entrained liquid.
A fluid compressor system comprising:
- a compressor having a compressor inlet and a compressor outlet, the compressor being configured to receive fluid at the compressor inlet and supply compressed fluid at the compressor outlet;
- a power source operably connected to the compressor to power the compressor to supply the compressed fluid;
- a separator tank in fluid communication with the compressor outlet to receive the compressed fluid and separate entrained liquid from the compressed fluid;
- and
- a control system, including one or more control devices configured to:
- determine a target operating temperature;
- and
- selectively operate the fluid compressor system in a condensation prevention mode to reduce condensation of water entrained within the compressed fluid, including controlling a system temperature of the fluid compressor system based on the target operating temperature.
A method for operating a fluid compressor system, the fluid compressor system being configured to supply a compressed fluid using power from a power source, the method comprising:
- determining, with a control device, a system temperature of the fluid compressor system;
- determining, with the control device, a target operating pressure based on the system temperature of the fluid compressor system;
- and
- operating the fluid compressor system, with the control device, in a water removal mode to one or more of:
- reduce a system pressure of the fluid compressor system to at or below the target operating pressure to vaporize water from the compressed fluid;
- or
- maintain the system pressure of the fluid compressor system at or below the target operating pressure to vaporize water from the compressed fluid.
