Airflow velocity in a residential HVAC market duct system is an important design consideration.
Although designing for proper velocity applies to all ducted HVAC construction systems — heat pumps, air conditioners, gas furnaces, etc. — geothermal HVAC market systems benefit from a slightly different design. Because of the location of the refrigerant-to-air heat exchanger on a self-contained geothermal unit, these systems lend themselves to a lesson in improved velocity for residential comfort systems.
