Compressor Compartment and Main Electric Panel (detailed;
see
Pic.D.1C
).
Compressor(s)
(13),
Receiver(s)
(14) and other components are located within the
Compressor Compartment
(3)
:
o
Each compressor circuit has glycol‐to‐refrigerant
plate heat exchanger
(16) and, common to both
circuits,
glycol pump
(16a), that circulates water/glycol to reject compressor‐generated heat.
o
Motorized water/glycol
Reheat
(79) and
AC
(80)
valves
’ opening position determines how much fluid
is diverted to respective coil(s) (reheat and fluid cooler or external heat sink).
o
If the dehumidifier has the standard
pool water heating
option, the compressor circuit additionally
includes the
coaxial pool water heat exchangers
(15) and refrigeration pool water heating solenoid
valves. Number of pool water heat exchanger varies based on dehumidifier type and capacity.
o
Control sub‐panel with
Main Control
Board
(17) and
Operator Panel
(18) is
normally mounted on the compressor
stand frame.
Main Electric Panel
(2) contains main
blower(s)
VFD
(variable frequency drive)
(78), main
Disconnect
(77), if one is
installed, and other electrical and control
components (contactors, fuses, control
transformer etc.).
Packaged
Outdoor Fluid Cooler
(19), if
dehumidifier is equipped with it, is
normally mounted at the end of the
dehumidifier, adjacent to compressor
compartment/supply air end (see Pic.
D.1D).
