Description

The Heat Capacitor component models a generic ideal heat capacity, where no geometry is assumed beyond the volume and the temperature is uniform for the entire mass. The heat capacity is assumed to be constant, that is, independent of the temperature.

If the parameter T0 is not set, this component assumes the default temperature of 20 °C at the start of the simulation and the heat capacity is calculated by

C=cpm

CdTdt=Qflow

The following table lists typical values for cp at 20 °C in JkgK:
