  • Patent number: 10172970
    Abstract: A method of maintaining a desired level of an aerosolized compound within a space to be treated with the compound, the method including providing a diffusion device with the compound in liquid form and a control system for operating the device. The control system includes a sensor in fluid communication with the air within the space to be treated configured to sense the concentration of the compound aerosolized within the space. The diffusion device is operated to diffuse the compound into the space. The concentration of the compound within the space to be treated is sensed with the sensor and operation of the diffusion device is altered based on the concentration of the compound sensed to achieve a desired concentration of compound within the space. The sensing and operation altering steps are repeated periodically to maintain the desired concentration of the compound within the space.

  • Patent number: 8855827
    Abstract: A method of controlling operation of a diffusion appliance to treat the atmosphere within an enclosed space. The method may include programming the operation of the appliance according to a control scheme specifying a flow rate of liquid to a diffusion means and a periodic operation of the diffusion means. Control schemes may be associated with different volumes of spaces to be treated by the appliance, the rate of decay of the liquid within the space to be treated and the level of concentration of the liquid desired within the space.

  • Publication number: 20090238716
    Abstract: A method and device of treating an enclosed space with a liquid disinfecting agent. A device diffuses small droplets of the liquid into the space and the droplets evaporate to leave gaseous disinfecting agent within the space to be treated. The concentration of the agent within the space may be preferably maintained at or near a saturation concentration for maximum efficiency and effectiveness. Operation of the device may be varied to match the atmospheric conditions within the space and the current level of concentration of the agent within the space.
