modelDryCoil
Calculates dry coil condition
Extends from Buildings.Fluid.DXSystems.Cooling.BaseClasses.PartialCoilCondition (Partial block for dry and wet coil conditions).
Information
This block calculates the rate of heating/cooling and the coil surface condition under the assumption that the coil is dry. The heat transfer calculations are done in Buildings.Fluid.DXSystems.BaseClasses.CapacityAirSource.
For a similar model that is used to compute the wet coil conditions, see Buildings.Fluid.DXSystems.Cooling.BaseClasses.WetCoil.
