Desiccant Paper
Polymeric desiccant articles and process for their manufacture
Articles comprising a substrate and a polymeric desiccant either
impregnated therein or coated thereon are disclosed as well as processes
for their manufacture. The invention also contemplates a process
for synthesizing a polymeric dessicant in particulate form for use
as such or for use as a coating material for desiccant articles.

The desiccant cooling cycle is a novel open heat-driven cycle which
can be used both to cool and to dehumidify air. Although desiccant
cooling systems have been used in Scandinavian buildings for over
20 years, they have only relatively recently been used in the United
Kingdom (UK). This paper describes the operation of a desiccant
cooling system at the University of Lincoln, which was among the
first facilities in the UK to install such a system. The desiccant
system at the University of Lincoln was monitored for the period
September 1998 to August 1999. The results of this monitoring programme
reveal the system to be an effective low-energy solution.

A review of desiccant cooling systems
This paper describes recent published design advances that have
been made in desiccant cooling systems.^In desiccant cooling cycles,
the desiccant reduces the humidity of the air by removing moisture
from the air.^Then the temperature is reduced by other components
such as heat exchangers, evaporative coolers, or conventional cooling
coils.^The main advantage that desiccant cooling systems offer is
the capability of using low-grade thermal energy.^Desiccant cooling
systems for residential and commercial applications are now being
used to reduce energy-operating costs.^However, the initial costs
are comparatively high.^The focus of research for the past decade
has been to develop desiccant systems with a high coefficient of
performance.^Recent studies have emphasized computer modeling and
hybrid systems that combine desiccant dehumidifiers with conventional
systems. |
