Advanced Humidity Control Equipment
Sponsors: Trane/FSEC/ORNL, SEMCO/ORNL, DryKor/NREL, and GTI
Under four separate projects, ERC evaluated
advanced humidity control systems integrating desiccant technology
(dehumidifiers or enthalpy exchangers) with conventional vapor compression
cooling coil equipment. In the first project with Trane, the Cromer
Cycle, that utilizes a desiccant enthalpy exchange device "straddling"
a cooling coil to increase moisture removal, was computer modeled
and annual simulations completed to identify building applications
that achieved improved humidity control economics. In the second
project with SEMCO, ERC tested alternative solid desiccant dehumidifier
matrix samples in the M&IE Sorption Test Facility to identify
better component selections and more cost effective equipment designs.
In the third project with DryKor, ERC developed a CFD analysis to
assess the magnitude of the various heat and mass mechanisms contributing
to the sustained operation of the liquid desiccant dehumidifier.
In the fourth and final project, ERC analyzed alternative supplemental
dehumidifiers for residential application, including design assistance
with a HVAC manufacturer and a white paper on residential dehumidifiers.
