Abstract
An air handling unit has a blower configured to selectively move air from an air inlet of the air handling unit to an air outlet of the air handling unit along an airflow direction extending from the blower to the air outlet, a heat exchanger disposed within the air handling unit between the inlet and the outlet, the heat exchanger has a thermal conductor, an evaporator tube thermally conductively joined to the thermal conductor, and a subcooler tube thermally conductively joined to the thermal conductor. An expansion device provides fluid communication between the evaporator tube and the subcooler tube and a drain pan disposed within the air handling unit upstream relative to the at least one subcooler tube and positioned in a geometrical footprint of at least a portion of the drain pan as the drain pan is viewed from an upstream position in the airflow direction.
