Desiccant Cooling Technology
Course Highlights

This online engineering PDH course provides an overview of how desiccant systems operate and how they can be of benefit. This course is based entirely on U.S. Army Construction Engineering Research Laboratory resource guide "Desiccant Cooling Technology" developed by U.S. Army Construction Engineering Research Laboratory. This course provides condensed information on desiccant technology, which will benefit reader to learn a significant amount in brief time frame.


Desiccants cooling technology provides a tool for controlling humidity (moisture) levels for conditioned air spaces. It offers numerous advantages over the more common vapor-compression and absorption units. For example, desiccant systems do not need ozone-depleting refrigerants and are very effective at treating the large humidity loads resulting from ventilation air. Also, they use natural gas, solar thermal energy, or waste heat, thus lowering peak electric demand.


The use of desiccant cooling and dehumidification systems into existing and new buildings has shown reduced energy costs, better health, greater comfort and increased productivity for building occupants. Recent advances in adsorptive materials, in conjunction with dehumidifier design innovations are making the technology increasingly attractive.


This 4 PDH online course is applicable to HVAC engineers, facility engineers, architects, environmentalists, operations and maintenance personnel, as well as consultants and contractors who construct, build and manage facilities.
