Description

The Pressure Increase component is a two-port thermal-fluid component that establishes a pressure increase from port a to port b. The temperature and enthalpy of the medium are not changed. When the `use`Δpinput is false, the pressure increase is set by the component parameter Δpconst otherwise the pressure increase is set by a signal input.

The Medium parameter specifies the name of a Thermal-Fluid Media record, which must be in the model at the same or higer level.

The Use default medium boolean parameter, when true, sets the name of the Medium parameter to fluidMedium1, which corresponds to the default name of a fluid medium record. To use a different name, uncheck the box and enter the name in the parameter input that appears.
