Single coil dual path dehumidification system

摘要

A dual path single coil dehumidification system is provided. The system includes a housing that is mounted onto the top of a building that is to be dehumidified. The system draws in outside air which is circulated along its own dedicated path. A cooling coil is disposed in the dedicated outside air path. The outside air therefore passes over the cooling coil and is dehumidified prior to being mixed with any other air. The system also draws in return air from the interior of the building. The system is arranged so that the return air is drawn over refrigeration units that are located in the building to cool the return air. The cooled return air is then drawn into the housing where it is mixed with the outside air only after the outside air passes over the cooling coil. The mixed dehumidified outside air and the cooled return air form a supply air stream that is delivered to the interior of the building.
