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 engaging building Smoke Mode Operation with air distribution systems wherein the Outdoor Air primary air damper is opened to 100% and the Return Air secondary air damper is closed to 0% for smoke mode purge operation, thus injecting 100% Outdoor Air primary air into a vessel or building envelope;

applying appropriate ACH (Air Changes per Hour) required to dilute total air of smoke content within a given period of time;

applying mover power (7) as needed to maintain the operating conditions (10) as varied or fixed;

and maintaining necessary system total constancy (5).

2. A method in accordance with claim 1 for engaging building Smoke Mode Operation with air distribution systems wherein building exhaust distribution systems are activated to provide exhaust air movement relative to atmosphere for smoke evacuation from a vessel or building envelope in coordination with primary air injection;

applying appropriate ACH (Air Changes per Hour) required to evacuate total air of smoke content within a given period of time;

replacing total air content with adequate primary air or makeup air changes;

maintaining a ratio of a minimum of 80% makeup air to 100% exhausted air;

applying mover power (7) as needed to maintain the operating conditions (10) as varied or fixed;

and maintaining necessary system total constancy (5).

3. The method of claim 2 wherein VAV (Variable Air Volume) terminals downstream of the system are indexed to their smoke mode sequence of operation, wherein

the terminals produce adequate air changes per zones served on a constant volume basis;

4. The method of claim 2 wherein all main branch or zone dampers are indexed to their smoke mode sequence of operation, wherein

the zone delineations produce adequate air changes per zone on a constant volume basis.

5. A system for engaging air handler smoke mode operation wherein a two-way and modulating damper actuator placed in bypass separates the RA from the EA plenum,

wherein an integrated exhaust system and secondary mover is isolated from the primary air handling system;

wherein exhaust airflow is diverted to atmosphere;

wherein primary outdoor air content is 100%;

and wherein return airflow is not recycled.

6. The system of claim 5 or 7 wherein if dry bulb immersion sensors situated in the RA or EA plenums indicate sensible heat to be approaching 100% of the total heat content, a warning indication of smoke or fire may be relayed.

7. A system for mixing airstreams and adjusting percentages of OA/RA (Outdoor Air/Return Air) content in air distribution systems in accordance with claim 5, which comprises

a ducted mixing box housing frame fitted with dual damper control and flow sensing stations in parallel operation;

an actuation means of modulating open or closed, allowing both air streams to be throttled and mixed in particular proportions of Outdoor Air primary air quantity and Return Air secondary air quantity at operating conditions set and maintained as per flow-pressure monitor sensor input;

a separate, effective ducting of outdoor air and return air channeling separated air streams into the mixing chamber;

a mixing chamber allowing air streams to be mixed where air is not stratified;

multi-point dry and wet bulb temperature sensors placed in each individual air stream and within the mixing chamber, where air is not stratified;

an integrated exhaust and return plenum separated by a two-way bypass damper connection;

a sensor relay alarm means triggering the mixing box, main damper control, and all downstream zone damper sequencing for smoke mode operation.
