A desiccant bundle is disclosed herein having front and back sheets
of porous fabric material joined about edge marginal regions and
across the middle to define a plurality of sealed compartments.
A multiplicity of multiple surface desiccant granules are situated
in each compartment for absorbing moisture in the fabric material
or passing through it. Hangers are provided for detachably securing
the desiccant bundle to supporting structure in a humid or wet environment.
A racket handle and dispenser is set forth wherein a magazine is
contained within an uppermost portion of the handle for containment
of a desiccant powder wherein a spring-biased first plunger adjacent
the magazine dispenses a portion of desiccant powder about an uppermost
portion of the handle wherein an aligned underlying second chamber
utilizes a second spring-biased plunger and associated valve to
dispense desiccant powder selectively to a lowermost portion of
A desiccant assisted air conditioning system for delivering dehumidified
refrigerated supply air into a conditioned space and with return
therefrom divided between recirculation air and exhaust-relief air
employed to remove heat resulting from dehumification and employing
waste heat from refrigeration for desiccant regeneration.
A rotary regenerative heat wheel having a heat exchange matrix
comprised of a spirally wound strip of plastic having a coating
of dry desiccant affixed thereto. The quantity of desiccant affixed
to the strip is selected so that the sensible and latent heat transfer
efficiencies of the wheel are relatively high and approximately
equal. An apparatus and method are disclosed for applying a desiccant
coating to a sheet of plastic.
