Self-regenerated hybrid dehumidifier with air purification

A self-regenerated method for removing moisture from process air comprising:

• providing an enclosure where the process air is treated;
• first ventilating the process air from a gas inlet of the enclosure through an air pathway to reach a plurality of thermal conductive elements;
• providing a superhydrophilic-nanostructured composite surface coated with one or more chemical-based adsorbents on the plurality of thermal conductive elements to be disposed within the enclosure in an orientation substantially perpendicular to the direction of air flow in the air pathway from the gas inlet in order to maximize contact rate per surface area of the superhydrophilic-nanostructured composite surface to a volume of incoming process air;
• providing a thermoelectric heater and cooler module having at least two water circulations respectively communicating with a liquid section of the plurality of the thermal conductive elements and with a heat storage member, one end of the liquid section of the thermal conductive elements more proximal to the superhydrophilic-nanostructured composite surface receiving a relatively cool water from the thermoelectric heater and cooler module while the other end of the liquid section of the thermal conductive elements more distal to the superhydrophilic-nanostructured composite surface transferring a relatively warm water to the thermoelectric heater and cooler module;
• the heat storage member including a material responsive to temperature change when the temperature of the water from the thermoelectric heater and cooler module exceeds a phase-transition temperature of said material of the heat storage member such that said material is converted from solid state into liquid state;
• second ventilating the air in the enclosure towards a direction which a maximum air flow rate first flowing through the heat storage member to carry away heat from said material of the heat storage member after being converted into liquid state followed by flowing through multiple gaps between each pair of two different vertical planes of the thermal conductive elements is provided to elevate the surface temperature of the superhydrophilic-nanostructured composite surface such that water molecules from the incoming process air absorbed by the one or more chemical-based adsorbents are ready to be released from the chemical-based absorbents;
• after said second ventilated air passing through the material of the heat storage member having been converted from solid to liquid state thereof by the relatively warm water at a temperature exceeding the phase-transition temperature of the material from the thermoelectric heater and cooler module, transferring the water after cooling by said ventilated air from the heat storage member back to the thermoelectric heater and cooler module in order to circulate a relatively cool water to the end of the liquid section of the plurality of thermal conductive elements more proximal to the superhydrophilic-nanostructured composite surface where incoming process air after passing through the gas inlet will first contact;
• cooling the superhydrophilic-nanostructured composite surface by the relatively cool water from the thermoelectric heater and cooler module to the liquid section of the plurality of the thermal conductive elements such that the proximal end of the plurality of the thermal conductive elements to the superhydrophilic-nanostructured composite surface maintains a surface temperature below a dew point temperature of the water molecules in the incoming process air.
