Abstract:
A VAV air handler includes a cooling coil with a return air bypass damper for improved dehumidification. The bypass interjects into the supply air a portion of relatively warm, dry return air downstream of the cooling coil. This allows the cooling coil to absorb more latent heat from the incoming outside air and the remaining portion of the return air over a broad range of operating conditions, but especially at low load conditions.
