An apparatus is disclosed for an improved air conditioning system
for admitting air from an exterior space, adjusting the temperature
and humidity of the exterior air and delivering the adjusted air
to an interior space of a structure. To compare the energy levels
of these two air streams an improved device brings both air streams
to the same temperature, so just the relative humidity has to be
measured to know which of these two air streams has the higher or
the lower energy level. Using the device in a control system for
a desiccant wheel, at least two temperature sensors are eliminateable.
Polymer-bound adsorbent beads are usable as a direct replacement
for conventional clay-bound beads in insulating glass unit manufacture
to eliminate the problem of dusting associated with conventional
beads. Polymer-bound beads provide good adsorption and superior
crush strength compared to clay-bound adsorbent beads previously
used in insulating glass units to desiccate the space between the
glass panes. The polymer-bound adsorbent beads may also be used
as a substitute for conventional desiccant beads in water adsorption
applications such as in bottle stoppers, sachets, blister packaging,
etc.
A method for protecting substrates used in the manufacture of semiconductors,
memory products, and other electronic devices from the effects of
moisture during transport and storage is disclosed. This method
involves the use of a cassette or box made from polycarbonate or
another material having similar hydroscopic properties, treating
the cassette or box to reduce its moisture content, and surrounding
the cassette or box, and the substrates held therein, with a moisture
barrier. This results in a package which will keep the substrates
dry and eliminates the need for a separate desiccant within the
package.
A method of drying a gas making use of the distillation of a liquid
desiccant, the method comprising the introduction of a stream of
make-up liquid containing water and of an organic solvent miscible
with water, the solvent being a more volatile solvent than water
under the conditions of the method and forming no azeotropes with
water, in an intermediate zone of an elongated vertical contact
and fractional distillation zone.
