Theory vs. Practice in Direct Evaporative Roof Spray Cooling
Abstract
This paper will examine in depth the development
of roof spray cooling in this country and elsewhere,
the theory and practice of roof cooling, and the
limits of system application.
While this relatively simple method of air conditioning has been around for some time, and is
being employed increasingly by large U.S. industrial firms, its operation, principles, and application, both empirically and practically, have not
been widely discussed.
The impact of roofing construction, building
location, and internal and external load on the
effectiveness of roof cooling will be considered.
Also discussed will be the theoretical and actual
effect of roof cooling on a facility's energy
consumption, and on internal temperature variations where there is no mechanical air conditioning.
A complete survey of most studies and findings
to date will be presented. Guidelines for consideration of roof spray cooling systems will be
developed incorporating ASHRAE methodology.
