Information

This model calculates the nominal fuel power (W) for nominal conditions.

The nominal adiabatic efficiency (reference is the higher heating value (includes vaporization enthalpy)) comes from the SDF and depends on:

• Nominal return temperature (TRet_nominal)
• Nominale temperature difference (TSup_nominal-TRet_nominal)
• Nominal relative temperature difference (1)
• Nominal relative water mass flow (1)

Further assumptions are taken into account for nominal losses: Thermal conductance is described by a fit 0.0465 * QNom/1000 + 4.9891 based on manufacturere data at a temperature difference of 50 K to ambient
