Desiccant

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 Commonly encountered pre-packaged desiccants are solids that absorb water Desiccants for specialized purposes may be in forms other than solid and may work through other principles such as chemical bonding of water molecules

A Guide to Desiccant and Compressor Dehumidifiers

Desiccant dehumidifiers use a desiccant material typically Zeolite which absorbs water vapour from the air in a similar way to silica gel A fan draws air into the dehumidifier and passes it through a section of a slowly rotating wheel which holds desiccant which dries the air The moisture is extracted from the desiccant by heating a portion

Minimize lifecycle cost of desiccant dehumidifiers

Jan 01 2009Desiccant dehumidifiers use a desiccant wheel to dehumidify the supply air A dry desiccant wheel absorbs moisture from the supply airstream The heat of vaporization of the moisture as it is absorbed increases the air temperature in a constant enthalpy process Once the wheel has absorbed the moisture the moisture must be driven off of the

How Desiccant Dehumidifiers Work (Part I)

The blower on a desiccant moves the air through the desiccant wheel Most portable desiccant dehumidifiers use a single blower Normally 75 percent of the air is dried and sent through the wheel exiting the unit as warm dry process air The remaining 25 percent of the air is used to remove moisture from the wheel exiting the unit as warm

Benefits Offered by Passive Dehumidification Wheel Speed

When the PD wheel speed is increased its function can be changed from a dehumidification wheel into an effective total energy wheel Due to the much greater mass associated with the increased desiccant loading the PD wheel does not need to reach the rotational speed associated with the total energy wheel to achieve the desired performance

Desiccant Dehumidifier Reviews

A compressor based dehumidifier uses a compressed refrigerant to cool metal coils (evaporator coils) The hot humid air that enters the dehumidifier condenses on these cool coils This leaves the air that exhausts out of the dehumidifier still warm but drier than when it entered Desiccant dehumidifiers work quite differently Instead of using condensation (on Read More

The Impact of Relative Humidity Heat of Adsorption and

With the passive dehumidification wheel the return airflow is typically 60 to 90% of the supply airstream while the regeneration flow of an active desiccant wheel is usually only a small fraction (25 to 33%) of the supply airstream Figure 1 Sample active desiccant wheel performance 333 cfm 142 F 194 grains 21% RH 1 000 cfm 85 F 80 grains

Desiccant Dehumidifiers
