modelCondenser
Extends from BaseClasses.Icon_TwoVolume, TRANSFORM.Fluid.Volumes.BaseClasses.PartialVolume_wlevel (Base class for volume models).
Information
- As the liquid level goes to zero, the drain enthalpy will approach the mixed volume enthalpy. This will most often result in too low pressure, and is protected with an assert(p>1000 Pa).
- The drum liquid level should not be too large, an assert is triggered when the condenser gets full.
