.Buildings.Fluid.Sources.Outside_Cp

Information

This model describes boundary conditions for pressure, enthalpy, and species concentration that can be obtained from weather data. The model is identical to Buildings.Fluid.Sources.Outside, except that it allows adding the wind pressure to the pressure at the fluid port ports.

The pressure p at the port ports is computed as

p = p_w + C_p 1 ⁄ 2 v² ρ

where p_w is the atmospheric pressure from the weather bus, C_p is the wind pressure coefficient, v is the wind speed from the weather bus, and ρ is the fluid density. If use_Cp_in=true, then the wind pressure coefficient is obtained from the input connector Cp_in. Otherwise, it is set to the parameter Cp.
