This installation is used to

dehumidify a whole house and

also a separate unconditioned

space like an unfinished

basement or an area where

circulation of air from that

location throughout the house

is undesirable. Four dampers

are installed.

In whole house mode

(Figure 6), whenever the

HVAC blower turns on, air is

pulled from the return duct,

dehumidified, and returned to

the HVAC system downstream

of the cooling coil in the main

supply duct.

In localized mode (Figure 7)

the four-damper configuration

cuts out the HVAC ducting and

opens the ducting to the

unconditioned space, pulling

and returning air from this area

alone. This keeps the living

space and unconditioned

spaces separate.
