Cooler; Condenser; Motor-Compressor; Muffler - Carrier AquaEdge 23XRV Start-Up, Operation And Maintenance Instructions Manual

The cooler (also known as the evaporator) is
Cooler —
maintained at low temperature/pressure so that evaporating
refrigerant can remove heat from the liquid flowing through its
internal tubes.
This vessel is located underneath the
Condenser —
compressor. The condenser operates at a higher temperature/
pressure than the cooler and has liquid flowing through its
internal tubes to remove heat from the refrigerant.
Motor-Compressor —
tains system temperature/pressure differences and moves the
heat carrying refrigerant from the cooler to the condenser. See
Fig. 8.
The muffler provides acoustical attenuation. A
Muffler —
check valve just downstream of the muffler prevents reverse
compressor rotation during shutdown.
The control center is the user inter-
Control Center —
face for controlling the chiller and regulating the chiller's
capacity to maintain the proper chilled liquid temperature. See
Fig. 9. The control center:
• registers cooler, condenser, and lubricating system pressures
• shows chiller operating condition and alarm shutdown
conditions

• records the total chiller operating hours, starts, and the
number of hours the chiller has been currently running
• sequences chiller start, stop, and recycle under microproces-
sor control
• provides access to other Carrier Comfort Network
• provides machine protection
Storage Vessel (Optional) —
vessels are available. The vessels have double relief valves,
a magnetically coupled dial-type refrigerant level gage, a
1-in. FPT drain valve, and a
for the pumpout unit. A 30-in.-0-400 psi (–101-0-2750 kPa)
gage is also supplied with each unit.
NOTE: If a storage vessel is not used at the jobsite, factory-
installed optional isolation valves may be used to isolate the
chiller charge in either the cooler or condenser. An optional
pumpout compressor system is used to transfer refrigerant
from vessel to vessel.
