Dehumidification system and heat exchanger for the same

A heat exchanger for a dehumidification system, the heat exchanger comprising:

• a first zone defining a first airflow section configured to receive a portion of an airflow passing through the heat exchanger, the first zone extending parallel to an air inlet of the heat exchanger;
• a second zone defining a second airflow section configured to receive another portion of the airflow passing through the heat exchanger, the second zone extending parallel to the air inlet;
• a coolant coil including a first coolant coil section and a second coolant coil section each configured to cool the airflow;
• and
• a reheat coil including a first reheat coil section and a second coil section each configured to heat the airflow,
• wherein the first zone includes the first coolant coil section and the first reheat coil section to at least partially dehumidify the airflow within the first zone.

A heat exchanger for a dehumidification system, the heat exchanger comprising:

• a plurality of zones, each of the plurality of zones defining respective airflow sections configured to receive a portion of an airflow passing through the heat exchanger;
• a coolant coil including a plurality of coolant coil sections configured to cool the airflow, a first coolant coil section of the plurality of coolant coil sections disposed in a first zone of the plurality of zones and having a refrigerant inlet, and a second coolant coil section of the plurality of coolant coil sections disposed in a second zone of the plurality of zones and having a coolant coil outlet;
• and
• a reheat coil configured to heat the airflow, the reheat coil including a plurality of reheat coil sections, a first reheat coil section of the plurality of reheat coil sections disposed in a third zone of the plurality of zones and having a reheat fluid inlet, and a second reheat coil section of the plurality of reheat coil sections disposed in a fourth zone of the plurality of zones and having a reheat coil outlet,
• wherein each of the plurality of zones includes a portion of the coolant coil and a portion of the reheat coil to at least partially dehumidify the airflow.
