Dilution Air Processing Unit (DAPU) for Reduced Transmission of Airborne Infectious Diseases

An easily implementable, low-cost solution that reduces the transmission of airborne infectious diseases by supplying 100% fresh air to buildings.

HVAC system with ducts and monitoring equipment in an industrial setting.

Technology overview

A well-ventilated system can reduce the spread of airborne infectious diseases like COVID-19 in indoor spaces. RP has developed an innovative solution for enhanced ventilation and reduced transmission of airborne infectious diseases by employing an air ventilation technique which allows the creation of zones (e.g. sickbays, waiting rooms, etc.) within workplaces with no recirculation of air. This prevents cross-contamination of unclean air between the zones.

Technology features

  • 100% air change per room volume by fresh air in contrast to the nominal 25% to 30% using traditional mixed ventilation.

  • Reduce airborne particle exposure by greater than 60%.

  • Achieve 25% energy efficiency in providing 100% fresh air supply as compared to conventional systems.

  • Use a fully portable modular approach.

  • Can be easily retrofitted to any existing air-conditioning system.

Potential applications

  • Isolation rooms in hospitals

  • Sick bays on campus or in business places

  • Swab stations

  • Waiting rooms

  • Hotels and other premises to be used for quarantine purposes

  • Any area without an existing air-conditioning system

Benefits

  • Highly versatile with its portable and modular design.

  • 100% fresh air supply with no recirculation.

  • Easily implementable and low-cost solution.

Commercialisation

  • This technology is available for licensing and technology transfer.
