modelSpeedCorrectionLatent
Extends from Buildings.Fluid.HeatExchangers.ThermalWheels.BaseClasses.SpeedCorrectionSensible (Sensible heat wheels).
Information
This model calculates the power consumption, the sensible heat exchange effectiveness correction, and the latent heat exchange effectiveness correction of an enthalpy wheel when it is in different rotational speed.
The calculation of the power consumption and the sensible heat exchange effectiveness correction is described in Buildings.Fluid.HeatExchangers.ThermalWheels.BaseClasses.SpeedCorrectionSensible.
The latent heat exchange effectiveness correction is calculated using a cubic hermite spline interpolation of the latent heat exchange effectiveness dataset (see Buildings.Fluid.HeatExchangers.ThermalWheels.Data.Characteristics.HeatExchangerEffectiveness).
