Model for an evaporator or condenser with the use of a capacity to simulate heat losses.
Used in BuildingSystems.Fluid.HeatPumps.ModularReversible.Modular and BuildingSystems.Fluid.Chillers.ModularReversible.Modular, the heat flow to or from the volume is calculated in a black-box. Thus the heat is directly added to the medium.
Transient heat losses are modelled by adding a capacity
and two convection components to
BuildingSystems.Fluid.Interfaces.TwoPortHeatMassExchanger.
One of the convection component is between the capacity and the volume
(with thermal conductance GInn) and the other between
the capacity and the ambient heat port (with GOut).
Both GInn and GOut are constants
but declared without a parameter keyword so that
the calculation can follow a temperature or flow-rate based approach.
