Abstract
A method and apparatus for balancing an HVAC system. The method involves using a plate which is circular in shape and has four inner cut-out portions which are capable of being manually removed by an operating engineer. To reduce flow to a minimum, all four rings are left on the plate. To allow a progressively greater amount of air flow, more rings are removed from the circular plate. Such enables the equalization of the various rooms in an HVAC system without the addition of costly upstream dampers. The circular plate is attached to a duct via four small protruding ear elements.
Claims1
A method of balancing and equalizing a heating, ventilating and air conditioning system comprising the steps of:
- placing a flow regulating and metering plate in a flexible duct leading to a room to be heated or cooled,
- wherein the plate includes four inner removable ring elements,
- the plate further including four outer attaching elements,
- removing an intermost ring to allow more air flow to a room to be heated or cooled,
- wherein progressively more rings are removed to allow more air to flow to a desired area,
- wherein the inner removable ring elements are flat in shape and, before removal, lie in the same plane with an outer flat portion of said plate,
- wherein the inner removable ring elements are are spot welded to each other,
- wherein the four outer attaching elements are in contact with the flexible HVAC duct(107).
