OAIRO | Technology

The OAIRO atomixAir Dynamic Diffusion (aDD)-HVAC air management BMS/BAS/BEMS software control algorithm independently and incrementally controls the supply and return air within an indoor zone to create atomixAir Dynamic Diffusion. OAIRO aDD-HVAC will stop convection bulk-motion and stratification build-up and maintain the indoor zone at a consistent temperature with optimal air quality, as demanded by in-zone sensors or mobile app.
 

OAIRO delivers:

 

  • Temperature control within 0.1 °C increments
  • System holds set point at +/- 0.5°C
  • Humidity control
  • CO2 and particulate monitoring and control
  • Energy consumption reporting and management
  • Consistent and continual systems monitoring and reporting
  • No re-commissioning requirements
  • OAIRO PDQbms - build-out your BMS system in hours, not days or weeks

 

OAIRO aDD-HVAC air management saves up to 73% of the energy used by most currently installed HVAC systems. OAIRO does this by utilising the latest available, proven technologies to give precise, incremental control over all associated systems to create OAIRO atomixAir Dynamic Diffusion, for calm and consistent air patterns. OAIRO aDD-HVAC air management requires a building to have a dual-duct ventilation infrastructure, installed to regulated international standards.

 

For new build projects, OAIRO can provide a complete MEP specification and PDQbms service. For retrofit projects, OAIRO provides an MEP and PDQbms service to rapidly migrate your current HVAC system to an OAIRO aDD-HVAC solution. OAIRO installation projects are fully supported by our extensive portfolio of OAIRO aDD-SERVICES.

 

OAIRO's unique atomixAir Dynamic Diffusion provides the opportunity to refresh conventional thinking for all design aspects of a dual-duct HVAC system, maximising the opportunity to save energy, to reduce emissions and improve human well-being.


OAIRO PDQbms software cuts the BMS migration build-time down to hours, not days or weeks.  Contact us now, to start your OAIRO aDD-HVAC migration journey today.

Technology - Frequently Asked Questions

What's different about OAIRO systems design
atomicAir Dynamic Diffusion

OAIRO is different from conventional HVAC systems as it micro-controls HVAC plant and in-zone supply, return and mixing air dampers incrementally and dynamically based on real-time sensory information. The entire system is micro-controlled by the OAIRO software algorithm to create atomixAir Dynamic Diffusion.

International Standards
Ashrae

Systems designs conform to Ashrae International Standards where geographically applicable.

Systems designs conform to CIBSE International Standards where geographically applicable.

Design & Installation
Produce Load Calculations

Produce Load calculations based on supply air at 10 - 12º (for cooling) upto 45º for heating)

Design & Size Ductwork

Design & size ductwork based on supply air at 10 - 12º (for cooling) upto 45º (for heating) to ASHRAE Variable Air Volume standards

Supply & Extract Dampers

Close fitting dynamic damper/actuators to each room supply & extract (extract may be common on the zone)

Riser Damper

Close fitting dynamic damper/actuators on each leg from riser

Static Pressure

Static pressure sensors in risers & legs

Room Control
OAIRO Controller

OAIRO controller/sensor – Temperature, Humidity & CO2 (VOC & Lux may be added)

Supply & Extract Duct

Supply and extract duct, dynamic actuators-dampers and grilles

Dampers

Supply and extract duct, dynamic actuators-dampers and grilles
Close fitting damper and actuator dynamically controlled by the OAIRO algorithm

Mode of Operation

1 - OAIRO atomixAir
2 - Traditional VAV – with air quality control

Plant Control

The system's high flexibility with atomixAir makes it possible to:

  • fulfil numerous architectural requirements or wants and needs that are unachievable with a traditional system
  • The supply air can be fed into the room at a higher temperature difference than with a conventional system (heating: max.45°C; cooling: min. 10°C)
  • This makes it possible to optimise the AHU components and the duct network/sizing
  • OAIRO exhaust air extraction is much easier than with a conventional system
  • OAIRO enables a shared exhaust air duct in a central location. This eliminates time-consuming exhaust air ducting
  • A large increase in building diversity

Example Specification - Ductwork design:

  • Ductwork sized based on 10-12 degree supply
  • Legs “Static Pressure sensors” controlling” Leg Damper”
  • Riser “Static Pressure sensors” controlling” Riser Feed Damper”
  • Optimum diffusers – Although the air will take effect within 20cm of the grille
Plant
Example Specification - Plant:
  • Unit Demand diversity 12.5% - 100% (with a linear power curve as possible)
  • Example Plant diversity (Variable Flow/Temperature plant)
  • EC Fans
  • VFD’s / Variable flow pumps with optimisation
  • Unique Sensors Set
  • Pressure measurement in the supply & return within AHU
  • Heat and coolth recovery
  • All dampers operate dynamically via OAIRO BMS
  • Humidification - all humidification types can be actuated
  • Coils Misting system (Supplied from condensation collection)
  • Power Monitoring and Analysis
