A vehicle able to recover CO.sub.2 includes a CO.sub.2 recovery container holding an adsorbent adsorbing CO.sub.2 in gas. The vehicle is configured so that the adsorbent is taken out from the vehicle.

A dehumidifying air handling unit for an HVACR system includes a housing, a desiccant wheel, and a cooling heat exchanger. A main airflow path extending through the housing from an air inlet to and air discharged outlet of the housing. The desiccant wheel includes a first end and a second end that are each disposed in the main airflow path and a metal organic framework desiccant that is moved between the first end and the second end. A desiccant wheel includes a metal organic framework desiccant disposed on a surface of the desiccant wheel. Rotation of the desiccant wheel moves a position of the surface between a first end and a second end of the desiccant wheel. The metal organic framework desiccant has an majority absorption-desorption operating band of 25% relative humidity or less.

Provided herein are water harvesting systems, as well as methods using such systems, for capturing water from surrounding air. The systems and methods use water capture materials to adsorb water from the air. For example, the water capture materials may be metal-organic-frameworks. The systems and methods desorb this water in the form of water vapor, and the water vapor is condensed into liquid water and collected. The liquid water is suitable for use as drinking water.

The present disclosure relates to a gas purification apparatus and a trace substance detection device. The gas purification apparatus includes a first purification component, a second purification component and a switching component, wherein the switching component can be switched between a first state and a second state, the first purification component and a component to be purified form a gas purification loop in the first state, and the second purification component can provide a regeneration gas for the first purification component in the second state, so that water vapor and impurities in the first purification component are discharged to outside. In the gas purification apparatus, the filtered air is used as the regeneration gas to prevent secondary pollution in a recycling process of the purificant; furthermore, by means of the state switching function of the switching component, the mutual interference between the two working states of purification and regeneration can be prevented, and all the above advantages can improve the reliability of the recycling of the purificant, thereby optimizing the performance and the service life of the gas purification apparatus.
