Closed-Loop Antimicrobial Gas Generation for Household Disinfection

The system is divided into separate functional modules: a generation subsystem that produces ClO2 gas from precursor chemicals, a distribution subsystem that disperses the gas through HVAC or direct venting, and a control subsystem that monitors concentration and regulates operation. This segmentation allows each component to be optimized independently, enabling compact household-scale deployment while maintaining effective disinfection capability.

The patent uses HVAC systems or building infrastructure as intermediaries to distribute the antimicrobial gas throughout enclosed spaces. This intermediary approach eliminates the need for large standalone generation systems in each room, as the gas is centrally produced and distributed through existing ventilation pathways, significantly reducing the physical footprint required.

The system employs precise control of reaction parameters including temperature, pressure, and reactant flow rates to optimize ClO2 generation. By maintaining specific parameter ranges (e.g., controlled heating rates, regulated chemical mixing ratios), the system achieves both rapid generation and high-purity ClO2 output, eliminating the slow, low-quality production associated with conventional methods.

The control subsystem continuously monitors ClO2 concentration in the enclosed space using sensors and adjusts the generation rate accordingly. This feedback mechanism ensures that the system produces exactly the amount of ClO2 needed at the right time, preventing both insufficient generation and excessive production that would compromise solution quality. The system can detect and respond to concentration variations in real-time, maintaining optimal production conditions.
