System and method for HVAC condensate management

摘要

A HVAC system includes a cabinet configured as a duct, a coil assembly disposed within the cabinet, and at least one barrier configured to substantially segregate a low pressure zone associated with a downstream side of a heat exchanger of the coil assembly from a high pressure zone, wherein a leakage path is provided between the high pressure zone and the low pressure zone.

主权项

1. A method of managing HVAC condensate, comprising:
providing a cabinet configured as a duct; providing a coil assembly having a first slab and a second slab configured in a V-shaped coil arrangement within the cabinet; substantially segregating a low pressure zone associated with a primary airflow through the cabinet from at least one high pressure zone; disposing a slab cap over an upper end of each of the first slab and the second slab, each slab cap comprising at least one undulating disturber disposed near an upper portion of each of the first slab and the second slab within the low pressure zone; disturbing the primary airflow with the undulating disturbers to locally reduce a velocity of the airflow to reduce an amount of condensation being transported through reduced velocity regions; and providing an air leakage path between the low pressure zone and the high pressure zone to allow airflow to transfer from the high pressure zone to the low pressure zone to reduce an amount of condensation leaking from the low pressure zone to the high pressure zone.
