The literature I have seen suggests that humidity capacitance
multipliers typically range from about 5 to 15. The value is a
multiplier on the humidity capacitance of the air in the zone. If
you have set a value of 5 then you're telling Type56 that the zone
can absorb 5 times as much moisture as can be absorbed by the air in
the zone. If you increase the value then your zone's humidity ratio
will change more slowly. The humidity ratio will not necessarily
increase overall. If you are concerned about the humidity level then
check to make sure that you are applying a reasonable amount of
outdoor air ventilation to your zones and also make sure that you
have accounted for latent energy gains in the zone not only from
people but from other sources as well.<br>
kind regards,<br>
