An innovative desiccant dehumidification HVAC system has won Trane
the 2006 Frost & Sullivan Product Innovation of the Year Award. This
award is presented annually to a company that has demonstrated excellence
in new products and technology in its industry.
In announcing the award, it was noted that Trane extended “a
lot of credit” to FSEC’s Charlie Cromer, who originated
the CDQ™ (Cool Dry Quiet) concept and obtained several patents
for the technology. Trane licensed the technology from him and
used it to develop their award-winning system.

In 2001, Cromer assembled a team that included FSEC, Trane, the University
of Chicago and desiccant wheel manufacturers, and obtained
a contract from the U.S. Department of Energy (DOE) to do
prototype work and testing on this technology. DOE was interested
because, theoretically, the cycle showed promise in reducing
the energy needed for moisture control. “This is an excellent
example where the federal government, through DOE, university research,
and industry, were able to collaborate very successfully,” Cromer
said.

Trane’s CDQ system was an outgrowth of the need to give industry
high-efficiency dehumidification capacity. There are many products
that control humidity but they have limited moisture control
or they are energy inefficient. But with growing concern about
mold and mildew, companies are looking for ways to control humidity
as they control temperature. Trane’s CDQ system meets this
market need by providing an efficient method of controlling
humidity as compared to the traditional over-cool-then-reheat
process.
Cromer pointed out that “Typical systems provide just a thermostat
to control temperature. The CDQ provides the building operator with
the ability to dial in the relative humidity they want in the space.
Not only does the Trane system provide much more capacity to control
humidity, it also provides this control at substantial energy savings
over alternative technologies.”
