Dehumidifier Optional Arrangement.
Two-Compressor Arrangement
Standard Quest IQ Evolution Series HVAC system normally has two compressors.
•Two-Compressor (or “Double-Decker”) dehumidifier (shown on Pic. C.2). It is composed of two identical
single-compressor dehumidifiers, one installed on top of
another and controlled as a single dehumidifier (each deck
is equipped with one compressor/refrigeration circuit).
Two-Compressor Arrangement –Dehumidifier Model
Dehumidifier typical arrangement, total capacity, and number of
compressors are reflected in its model (for specific dehumidifier
model refer to its Main Label –see Specific Data Info below), as
illustrated in example below:
•AG204 - double-deck two-compressor dehumidifier (composed
of two identical dehumidifiers AG002).
Most often, “Double-Decker” dehumidifier comes as two horizontal
“decks”, one “stacked” on the top of another; however it could also
be composed of two “decks”, installed side by side or separately,
still being controlled as one dehumidifier.
Air Conditioning Option –Dry Coolers (OAFC).
Basic views of standard air conditioning option is shown below on Pic. C.3 (coolers, NG models); standard
combinations of the dehumidifier and respective air conditioning option (based on their capacities) are shown in
Table C.1.
* Table C.1 shows standard dehumidifier and cooler
combination; depending on number of factors, dehumidifier
may have different cooler provided with it - refer to the
dehumidifier’s submittal documentation for more details.
** The pump package is optional - the dry cooler may
be provided without it.
In some cases, multiple dehumidifiers could be served by one common larger dry cooler.
Such common fluid cooler would normally be sized based on accumulative capacity of the dehumidifiers and,
respectively, could be comprised of multiple NG-V-12 fluid coolers, all operating as one.
