The desiccant absorbs moisture from the air leaving the cold surface, releasing heat and drying the air, which can be used in a process requiring dry air. The desiccant is then dried by an air stream at a lower relative humidity, where the desiccant gives up its moisture by evaporation, increasing the air's relative humidity and cooling it ...
A desiccant wheel is very similar to a thermal wheel, but with a coating applied for the sole purpose of dehumidifying, or "drying", the air stream. The desiccant is normally silica gel . As the wheel turns, the desiccant passes alternately through the incoming air, where the moisture is adsorbed , and through a “regenerating” zone, where ...
Desiccant dehumidifiers can operate at lower temperatures as the unit does not need cooled coils. Initial installation costs have limited the acceptance of desiccant dehumidification, worsened by lack of understanding of operational benefits, lack of technology awareness, and company priorities.
A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop units or in the exhaust gases of an industrial process, in order to recover ...
Canisters are commonly filled with silica gel and other molecular sieves used as desiccant in drug containers to keep contents dry. Silica gel in a sachet or porous packet. A desiccant is a hygroscopic substance that is used to induce or sustain a state of dryness (desiccation) in its vicinity; it is the opposite of a humectant.
The French mint will replace a number of medals after complaints from Olympians and Paralympians that their medals have begun to deteriorate less than six months after 2024 Paris Olympics ended.
Todd Bridges is proud of the work he's put in to reach three decades of sobriety.. The Diff’rent Strokes alum, 59, appeared on the latest episode of the Allison Interviews podcast and opened up ...
Here a wheel of inert material with small air passages parallel with the direction of air flow contains the desiccant. (Visualize a roll of corrugated cardboard 8 to 16 inches deep) The wheel exposed a tremendous amount of surface area coated with desiccant for the air to contact.
