6.1 WATER SYSTEM
A. MOTOR/PUMP ASSEMBLY: The motor/pump assembly
circulateschilleduidtotheprocessloop.Thepumpassembly
is built of total stainless steel to maintain water quality.
B. RESERVOIR. The vented reservoir is sized for the chiller
applicationtosupporttheowrate.Thereservoirprovidesa
stable water temperature under varying load conditions.
6.2 REFRIGERATION SYSTEM
A. COMPRESSOR: Compressors take low pressure/low
temperature refrigerant gas and compress the gas into high
pressure/high temperature gas.
B. AIR COOLED CONDENSER: The air cooled condenser
removes heat from the compressed refrigerant gas. The action
causes the gas to “condense” into a liquid state still under
highpressure.Airowacrossthecondenserisachievedviaa
motor driven fan assembly or centrifugal blower.
C. WATER COOLED CONDENSER: The water cooled
condenser removes heat from the compressed refrigerant
gas. As the heat is removed, the gas “condenses” into a liquid
state, still under high pressure. Tube-in-shell condensers are
used on 15-30 ton models. Tube-in-tube condensers are
used on 5-10 ton models. Water regulator valves are used
on all models to control the refrigerant head pressure by
modulatingthecondenserwaterow.
D. FILTER-DRIER: Thelter-drierremovescontaminantsand
moisture from the liquid refrigerant.
E. LIQUID LINE SOLENOID VALVE: Controlled by the
instrument, this valve closes when the compressor cycles off
to prevent refrigerant liquid from migrating to the evaporator.
The valve opens when the compressor cycles on.
F. REFRIGERANT SIGHT GLASS: The refrigerant sight glass
indicates refrigerant charge and moisture content.
• Full refrigerant charge is determined by a clear liquid
ow.
• Bubbles indicate low refrigerant.
• Moisture content is indicated by the color of the
element.
• Element color is normally green.
• If the color of the element is chartreuse or yellow,
