Blow through air handler

摘要

An air handling unit includes an enclosure, a heat exchanger having a first section and a second section, wherein the heat exchanger is disposed within the enclosure, and at least one heating element substantially co-located with the heat exchanger within the enclosure. The at least one heating element is at least partially located between the first section of the heat exchanger and the second section of the heat exchanger.

1. An air handling unit, comprising:
an enclosure, including a plurality of sides, with an air supply opening in one of the plurality of sides for supplying air to ambient and an air return opening in another of the plurality of sides for returning air from ambient; a blower disposed within the enclosure and configured to provide an airflow via a discharge airflow path of the blower in a between the blower and the air supply opening downstream direction, the discharge airflow path having a longitudinal axis; a heat exchanger comprising a first section and a second section, wherein each of the first section and the second section comprises a plurality of fins, and wherein the heat exchanger is disposed within the enclosure downstream of the blower and in the discharge airflow path of the blower; and at least one electrically-powered resistive heating element substantially co-located with the heat exchanger within the enclosure and disposed downstream of the heat exchanger in the discharge airflow path of the blower, wherein the at least one electrically-powered resistive heating element is at least partially located between the first section of the heat exchanger and the second section of the heat exchanger, and wherein the plurality of fins of the first section of the heat exchanger and the plurality of fins of the second section of the heat exchanger are longitudinally oriented parallel to the longitudinal axis of the discharge airflow path in the discharge airflow path of the blower to stabilize an airflow exiting the heat exchanger prior to the airflow contacting the at least one electrically-powered resistive heating element.
