DX cooling coil operation
Extends from Buildings.Fluid.DXSystems.Cooling.BaseClasses.PartialCoilInterface.
Information
This block combines the models for the dry coil and the wet coil. Output of the block is the coil performance which, depending on the mass fraction at the apparatus dew point temperature and the mass fraction of the coil inlet air, may be from the dry coil, the wet coil, or a weighted average of the two.
