.Buildings.Fluid.Sources.MassFlowSource_WeatherData

Information

Models an ideal flow source, with prescribed values of flow rate and trace substances, with temperature and specific enthalpy from outside:

If use_m_flow_in is false (default option), the m_flow parameter is used as boundary flow rate, and the m_flow_in input connector is disabled; if use_m_flow_in is true, then the m_flow parameter is ignored, and the value provided by the input connector is used instead.

The same applies to the trace substances.

The Buildings.Utilities.Psychrometrics.X_pTphi block is used with the input data including pAtm, TDryBul, relHum from weather bus weaBus, to calculate X.

The same applies to the specific enthalpy.

Note, that boundary temperature, mass fractions and trace substances have only an effect if the mass flow is from the boundary into the port. If mass is flowing from the port into the boundary, the boundary definitions, with exception of boundary flow rate, do not have an effect.
