The Delta T Corporation.
The Delta T Corporation has announced the development of Sprinkool
evaporative roof-cooling systems, designed to save energy and increase
cooling efficiency for distribution centers, warehouses and breweries.
According to the company the systems are based on the ability of water
to remove large amounts of heat from roof though the process of
evaporation. The company reports that the currents systems is the result
of years of refinement. For example, Delta T says that spray heads now
include molded polymer filters that prevent minerals from clogging the
orifice, and lightweight polymer pipes have replaced the coppers pipes
previously used. Another development is computer control of the system.
Sensors in the roofing membrane provide temperature data to a computer,
which them calculates the amount of misting required for each roof
section. Misting takes place at a rate of 1 ounce per square foot per
hour, with evaporation of 1.5 gallons removing 12,000 BYUs of heat from
a roof. According to Delta T, maintenance of the system costs less than
for an air-conditioning system. Check www.sprinkool.com
