modelLi
Frosting suppression based on Li et al.
Extends from AixLib.Fluid.HeatPumps.ModularReversible.RefrigerantCycle.Frosting.BaseClasses.PartialIcingFactor (Partial model to calculate the icing factor).
Information
This model implements frosting surpression following Li et al. As the frosting surpression is not dependent on the heating or cooling mode, but rather just on the ambient conditions, this model should not be used together with a defrost control.References
