Unit Nomenclature Nameplate Engineering Data - York MILLENNIUM YCAR0315 Installation Operation & Maintenance

protect against nuisance safety trips below 4°C (40°F)
and reduce the possibility of cooler damage due to freez-
ing during chiller operation, the unit Micro-Processor
will automatically unload the compressors at abnor-
mally low suction temperature (pressure) conditions,
prior to a safety shut down.
• Process Brine Option – Process or other applica-
tions requiring chilled fluid below 4°C (40°F) risk wa-
ter freezing in the evaporator, which is typically over-
come by using anti-freeze. For these applications, the
chiller system incorporates brine (ethylene or propy-
lene glycol solution). The system design Leaving
Chilled Fluid Temperature must be provided on the
order form to ensure proper factory configuration.

• Thermal Storage Option – Thermal Storage re-
quires special capabilities from a chiller, including
the ability to 'charge' an ice storage tank, then pos-
sibly automatically reset for operation at elevated
Leaving Chilled Fluid Temperatures as required by
automatic building controls. The Thermal Storage
Option provides Ice Storage duty Leaving Chilled
Fluid setpoints from -4°C to -10°C minimum (25°F
to 15°F minimum) during charge cycle, with Reset
range to normal supply fluid temperature.
• Power Factor Correction Capacitors – Provides
compressor motor full load correction to a minimum
of 0.90 power factor.
