modelSimpleBoiler
Extends from SimpleGasBoiler.Base.PartialBoiler (Partial boiler model with setpoints, fluid ports and icon).
Information
1. Purpose of model
Model of a gas boiler using TransiEnt interfaces and TransiEnt.Statistics. Gas Consumption is computed using a constant efficiency and constant heat of combustion.
Other fuels can be used by changeing the calorific value of the fuel as well as the type of energy carrier for the model statistics.
2. Level of detail, physical effects considered, and physical insight
(Purely technical component without physical modeling.)
3. Limits of validity
(Purely technical component without physical modeling.)
4. Interfaces
Basics.Interfaces.Thermal.FluidPort In/Out - heat carrier ports (e.g. water) or Modelica.Thermal.HeatTransfer.Interfaces.HeatPort
Modelica.Blocks.Interfaces.RealInput Q_flow_set - setpoint for thermal heat
Basics.Interfaces.General.EyeOut
Basics.Interfaces.Gas.RealGasPortIn - combustion gas inlet
Basics.Interfaces.Thermal.HeatFlowRateOut
Basics.Interfaces.Thermal.MassFlowRateOut
5. Nomenclature
(no elements)
6. Governing Equations
H_flow_gas_demand * eta = -Q_flow_set
Q_flow_gen = inlet.m_flow * (outlet.h_outflow - inStream(inlet.h_outflow))
