Abstract

The described method and apparatus pertains namely to the HVAC (Heating, Ventilating, and Air Conditioning) industry, though its many functions extend into any and all forms of air-fluid movement, metering, distribution, and containment. Essentially, the scope of operation of the method and apparatus encompasses all forms of scientific and engineering measurement dealing with fluid dynamics, fluid statics, fluid mechanics, thermal dynamics, and mechanical engineering as they pertain to precise, articulated control of air-fluid distribution and delivery. The described method and apparatus offers complete, comprehensive, and correct utilization of air-fluid movers and terminal devices under unique sensor logic control, from initial lab testing stages through to equipment cataloguing, selection, design and construction of any and all air-fluid distribution systems in entirety, whereas previously there was no such cohesive, total and terminal method of control for these systems or their components.

Claims

1. A method for controlling axial mover-system performance wherein

through motor control actuation, a terminal device control damper is throttled against ducted or piped axial mover discharge flow

adjusting and tuning damper control to specific damper positioning or valve constants;

applying specific mover constants;

thus increasing BHP (Brake Horse Power) and system pressure at specific operating points.

2. A method for controlling axial mover-system performance as recited in claim 1 wherein

through motor control actuation, axial mover fan blade pitch angle (11) is increased or decreased, attaining specified mover constants (11) and flow-pressure rates (2) at a given blade angle, BHP, and specific operating point (10).

3. A system in accordance with claim 1 comprising an axial mover effectively ducted to a diverging or expansion fitting member (5) with a dampering device situated at the point in the ducted distribution system of peak static regain allowing means to adjust to optimal (10) mover and valve constants (11), achieving peak system pressure and BHP with minimal loss of Vp (Velocity Pressure).

4. A packaged air handling system in accordance with claim 1 or 2 wherein a first primary axial mover of larger or smaller capacity is packaged in-line or in series with a second secondary mover of centrifugal or radial type;

wherein the axial mover blades are equipped with actuators to modulate pitch angle;

wherein the axial mover housing contains a motorized damper fitted effectively downstream of the axial mover and upstream of the centrifugal mover to throttle its discharge output;

wherein the larger capacity mover is situated downstream of the smaller capacity mover.

5. A packaged air handling system in accordance with claim 1 or 2 wherein a first primary axial mover of similar capacity is packaged in parallel with a second secondary mover of centrifugal or radial type;

wherein the axial mover blades are equipped with actuators to modulate pitch angle;

wherein the axial mover housing contains a motorized damper fitted effectively downstream of the axial mover to modulate its discharge as a primary output nozzle for injection of primary discharge and induction or entrainment of the secondary discharge;
