Abstract: A dehumidifying air handling unit for a heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a housing, a hollow desiccant drum configured to rotate within the housing, and a heat exchanger disposed within the hollow desiccant drum. The hollow desiccant drum includes channels that extend through a sidewall that surrounds an interior space. A desiccant is provided in the channels. The heat exchanger is configured to cool air flowing through the interior space of the hollow desiccant drum. A method of conditioning air includes rotating a hollow desiccant drum within a housing and directing the air to pass through the hollow desiccant drum.

Abstract: The present invention relates to the field of air purification of indoor and/or domestic environments and has as its object a method for air purification and simultaneous photo-conversion of carbon dioxide to oxygen by exploiting a photosynthesis process of an algal culture comprised within an aqueous medium. The method according to the present invention therefore allows to purify the air of an indoor environment by abatement/solubilization of pollutants in the aqueous medium and reduction of CO2 contraction by photo-conversion into O2. The method according to the present invention further comprises the steps of illuminating and aerating said aqueous medium as well as a step of periodically maintaining said algal culture in a state of constant growth in order to optimize the photosynthesis of the algal culture.

Abstract: The present invention discloses an air filter cartridge for use in an air-purifying device for removing formaldehyde (methane, HCHO) and other aldehyde-like VOCs (Volatile Organic Compounds), and in certain embodiments amine-like VOCs, from indoor air. The air filter cartridge is made up of a casing containing a plurality of filament-like elements as a support and a mixture of one or more natural polyphenols and a catalyst integrated in said support as a powder, forming a sponge-like mesh. The air filter acts as an absorption filter, the sponge-like mesh reacting irreversibly with the aldehyde-like VOCs present in the air, generating a polymer in the form of a polyphenol-aldehyde resin inside the air filter. Due to this irreversible reaction, the air filter is capable of capturing formaldehyde, as well as other aldehyde-like VOCs that are less reactive than formaldehyde, amine-like VOCs and ammonia.

Abstract: An environment control system utilizes oxygen and humidity control devices that are coupled with an enclosure to independently control the oxygen concentration and the humidity level within the enclosure. An oxygen depletion device may be an oxygen depletion electrolyzer cell that reacts with oxygen within the cell and produces water through electrochemical reactions. A desiccating device may be g, a dehumidification electrolyzer cell, a desiccator, a membrane desiccator or a condenser. A controller may control the amount of voltage and/or current provided to the oxygen depletion electrolyzer cell and therefore the rate of oxygen reduction and may control the amount of voltage and/or current provided to the dehumidification electrolyzer cell and therefore the rate of humidity reduction. The oxygen level may be determined by the measurement of voltage and a limiting current of the oxygen depletion electrolyzer cell. The enclosure may be a food or artifact enclosure.

Abstract: Embodiments relate to systems and methods for fluidization in industrial hygiene applications. The method includes collecting air samples of contaminants onto the surface of fluidized activated carbon particulate as opposed to fixed-bed particulate. The adsorbates include toluene (a cyclic compound) and n-hexane (an open-chain compound). The obtained results are analyzed and discussed in terms of breakthrough times. The input parameters are the initial concentration of toluene or n-hexane in the air feed stream and the amount of the sorbent used. The feed flow rate is at 2 liters/min, and the temperature and humidity are kept constant at their prevailing laboratory conditions, i.e., 22±2° C. and 34±2% RH, respectively.
