<DIV><FONT size=4>Since becoming aware of equipment that uses heat to recharge
(dehumidify) desiccant, I have been intrigued by the idea of using heat to
recharge (dry out) desiccant to be used to adsorb humidity within a space.

size=4> shows a unit that uses hot water to recharge the desiccant that could
potentially be produced from solar energy. </FONT></DIV>
<DIV><FONT size=4></FONT> </DIV>
<DIV><FONT size=4>I have been contemplating the possibility of removable
desiccant that can be recharged by any heat source outside the thermal
zone. I have been incrementally upgrading my home thermal envelope to be
tight. I night flush the house during the summer and generally achieve 70F
with a high relative humidity of 80% in the morning. I am wanting the
identify how much desiccant would be required to dry that air to 50%RH at
75F. Since I live in a wooded setting, the active solar opportunities are
limited for recharging the desiccant. However, if the desiccant can be
removed, it can be carried to an outdoor heater or drier for recharging.
In my situation, I could take it to a solar dryer located in my field with full
sunlight. One could also put it on a wood stove located outside when
dehumidification is needed during rainy weather. Once a mass of desiccant
has been recharged(dried) it can be stored in a vapor tight container such as a
zip lock plastic bag until it is needed. In this way, one could stock up
on dry desiccant.</FONT></DIV>
<DIV><FONT size=4></FONT> </DIV>
<DIV><FONT size=4>Below I attempt to quantify the issues. I am hoping some
of the smart and knowledgeable people on this list might review the numbers to
see if I have I understand the issues correctly. For example, the delta
volume at 50%RH and 80%RH at 75F divided by delta humidity ratio should give me
the volume of a #humid air, at least at that temperature. If I am right,
1# of vapor (1 pint in liquid volume) occupies more than 21cf. That is a
huge volume expansion which give me some intuitive understanding of vapor
pressure. </FONT></DIV>
<DIV><FONT size=4></FONT> </DIV>
<DIV><FONT size=4>In locations with better solar access than I do, I would
propose the conversion of a thermal syphon solar air heater located on the South
side of the building be tasked with recharging desiccant in the Summer.
Many technical issues to be resolved to make that work. For now, I am focusing
on my situation using the removable desiccant. The question is how much
desiccant is needed. </FONT></DIV>
<DIV><FONT size=4></FONT> </DIV>
<DIV><FONT size=4>I have become re-familiarized with the Psychometric chart to
determine humidity ratio and volume, enthalpy at each combination of RH and
Temperature. From this information I attempt to determine the weight of
the humid air at both 50% and 80% RH at 75F. From these two conditions, I
determine of the change in humidity ratio and volume. Dividing the cf/#da(dry
air) into the zone volume to determine the #da in the zone. I multiply
that times the humidity ratio in #ha(humid air)/#da(dry air) to come up with the
actual weight of the vapor in the space. Since we only want to reduce
humidity to 50% and not bone dry, the humidity to be removed is only the
difference. </FONT></DIV>
<DIV><FONT size=4></FONT> </DIV>
<DIV><FONT size=4>I probed into a local university library to access the ASHRAE
references to read their 2 main articles regarding desiccants. I learned
that the solid desiccants physically a<U>d</U>sorb humidity through capillary
action as opposed to liguid desiccants a<U>b</U>sorbing humidity with a chemical
reaction. Page F32.4 was a chart that showed the adsorption capacities of
3 different properties. The Gel 8 which is described in comparison with
other desiccants has the capacity to adsorb .21 x weight of desiccant in vapor
at 70F. I think this is a Silica Gel. I am looking for a good source
of these desiccants. At any rate, the article also says that left in
contact with the humid air, the desiccant will adsorb vapor until it matches the
RH of the air. Therefore, the size of the mass of desiccant needs to have
the capacity to adsorb 100%RH vapor so that when it adsorbs 50% of that, the air
and the desiccant will be 50%RH, the target condition for comfort. I
imagine a fairly simple box in the thermal zone with a fan that circulates room
air through the desiccant until a humidity sensor switches off the fan when the
target humidity say 50% is achieved and cut on again when the humidity goes
above say 55%RH. </FONT></DIV>
<DIV><FONT size=4></FONT> </DIV>
<DIV><FONT size=4>The zone I show in my numbers is 24’x16’x8’=3072cf. If
my logic is correct, than I need 2x weight of vapor at 50%RH or weight of air at
</FONT></DIV>
<DIV><FONT size=4>100%RH divided by adsorption capacity of dessicant of .21 to
find required weight of desiccant of 34#. I think this is somewhat
oversized because we are starting out at 80%RH and not 100%RH.
</FONT></DIV>
<DIV><FONT size=4></FONT> </DIV>
<DIV><FONT size=4>I installed a Heat Recovery Ventilator in my house instead of
Energy Recovery Ventilator that allows latent heat recovery because I do not
have active dehumidification such as compressor driven refrigerant systems.
However, with this active desiccant removal, an ERV would be a key part of
reducing the vapor removal needed by drying out the incoming fresh air when it
is more humid than the outgoing stale air. A tight building with latent
heat recovery of ERV, allows for the possibility of using heat the recharge
desiccant that can be used to dehumidify indoor air to achieve comfort and
healthy conditions without refrigerant driven systems with their energy cost and
incremental environmental degradation that is inevitable with leaking
refrigerant. </FONT></DIV>
<DIV><FONT size=4></FONT> </DIV>
<DIV><FONT size=4>I do not have a person to review these issues with
locally. I hope this list will wade through the logic to identify my
errors and add to their own experiences on using desiccants. </FONT></DIV>
