  • Patent number: 11311831
    Abstract: This invention is directed to an air purification method capable of removing small aerosols and a wide size range of aerosols, with minimum aerosol radius smaller than 0.01 micron. The method humidifies the air in an enclosed space and produces supersaturation at a level of at least 12 percent in at least a portion of the enclosed space so that water vapor condenses on aerosols to form water droplets. The method also coalesces the water droplets formed by supersaturation using coalescence devices that can coalesce droplets with minimum radius smaller than 0.01 micron, thereby lowering the equilibrium supersaturation, enabling water droplets to grow faster, be more stable and easier to be removed compared to when coalescence is absent. The method dehumidifies the air so that the water droplets with captured aerosols are removed. Coalescence enables droplets to grow under a lower ambient supersaturation level, thus saving a considerable amount of energy.

  • Patent number: 11291930
    Abstract: A reserve tank has a container, an outlet component, and an inlet component. The outlet component and the inlet component are mounted on the container. The outlet component has an open end located at a center of the container. The inlet component has a branch portion mounted in the container and an inlet channel in the branch portion. Therefore, when the reserve tank is disposed obliquely, even though the reserve tank is not full of a working liquid and contains some gas, the gas can hardly flow into the open end of the outlet component. In addition, if some gas enters the container through the inlet channel and thus forms bubbles, the bubbles may move upward along part of the branch tunnels extending upward, so the entering bubbles are still far from the open end.
