Note that each of Air
, Refrigerant
, VariableFrequencyPower
and SineWavePower
have been modelled as Blocks, not just ValueTypes, so they can themselves carry value properties (some of which have units).
The block Refrigerant
can have a RefrigerantState
, and there are two fixed specialisations RefrigerantVapour
and RefrigerantLiquid
.
A S_
prefix convention indicates a flow of a signal, as opposed to a flow of a physical quantity, recalling that a Signal was chosen to model the digital TemperatureReading
.
And there is also a special convention (used mostly just for this trail because it mixes flow interaction types), the prefix FF_
indicates here the type of a Port that has both in and out flows and is modelled using the SysML Extension for Physical Interaction and Signal Flow Simulation (SysPhS) approach, such as FF_FluidFlowElement
and FF_HeatFlowElement
, which we'll learn about next .
