Specifications

The YORK YK Chillers, manufactured by Johnson Controls, offer a complete combination
of features for total owner satisfaction.
MATCHED COMPONENTS MAXIMIZE EFFICIENCY
Actual chiller efficiency cannot be determined by analyzing the theoretical efficiency of
any one chiller component. It requires a specific combination of heat exchanger, compressor,
and motor performance to achieve the lowest system kW/ton. YORK chiller technology
matches chiller system components to provide maximum chiller efficiency under
actual – not just theoretical – operating conditions.
REAL-WORLD ENERGY PERFORMANCE
Johnson Controls pioneered the concept of “Real-World Energy” to illustrate the energysaving
potential of focusing on chiller performance during off-design conditions. Off-design
is not only part load, but full load operation as well, with reduced entering condenser
water temperatures (ECWTs). This is where chillers operate 99% of the time, and where
operating costs add up.
YORK centrifugal chillers are the only chillers designed to operate on a continuous basis
with cold ECWT and full condenser flow at all load points, taking full advantage of Real-
World conditions. This type of operation benefits the cooling tower as well by reducing the
cycling of the fan motor and ensuring good coverage of the cooling fill.
YORK centrifugal chillers offer the most efficient Real-World operation of any chiller,
meaning lower operating costs and an excellent return on your chiller investment.
OPEN-DRIVE DESIGN
Hermetic motor burnout can cause catastrophic damage to a chiller. The entire chiller
must be cleaned, and the refrigerant replaced. YORK YK centrifugal chillers eliminate
this risk by utilizing air-cooled motors. Refrigerant never comes in contact with the motor,
preventing contamination of the rest of the chiller.
Insurance companies that offer policies on large air conditioning equipment often consider
air-cooled motors a significant advantage over hermetic refrigerant-cooled units.
HIGH EFFICIENCY HEAT EXCHANGERS
YORK YK chiller heat exchangers offer the latest technology in heat transfer surface design
to give you maximum efficiency and compact design. Waterside and refrigerant side
design enhancements minimize both energy consumption and tube fouling.

SINGLE STAGE COMPRESSOR DESIGN AND EFFICIENCY PROVEN IN THE MOST
DEMANDING APPLICATIONS
Designed to be the most reliable chillers we’ve ever made, YORK YK centrifugal chillers
incorporate single-stage compressor design. With fewer moving parts and straightforward,
efficient engineering, YORK single-stage compressors have proven durability
records in hospitals, chemical plants, gas processing plants, the U.S. Navy, and in other
applications where minimal downtime is a crucial concern.
In thousands of installations worldwide, YORK single-stage compressors are working to
reduce energy costs. High strength aluminum-alloy compressor impellers feature backward
curved vanes for high efficiency. Airfoil shaped pre rotation vanes minimize flow disruption
for the most efficient part load performance. Precisely positioned and tightly fitted,
they allow the compressor to unload smoothly from 100% to minimum load for excellent
operation in air conditioning applications.
AHRI CERTIFICATION PROGRAM
YORK YK chillers have been tested and certified by Air-Conditioning, Heating and Refrigeration
Institute (AHRI) in accordance with the latest edition of AHRI Standard 550/590 (IP).
Under this Certification Program, chillers are regularly tested in strict compliance with
this Standard. This provides an independent, third-party verification of chiller performance.
Refer to the AHRI site at: http://www.ahrinet.org/water_chilling+packages+using+vap

and Exclusions as some options listed herein fall outside the scope of the AHRI certification
program. For verification of certification, go to the AHRI Directory at www.ahridirectory.

PRECISION CONTROL OF COMPRESSOR OIL PRESSURE
Utilizing our expertise in variable speed drive technology and applications, Johnson Controls
has moved beyond the fixed head and bypass approach of oil pressure control. The
old approach only assures oil pressure at the outlet of the pump rather than at the compressor,
and allows no adjustment during chiller operation. The YORK YK chillers feature
a variable speed drive oil pump, monitoring and providing the right amount of oil flow to
the compressor on a continuous basis. This design also provides sophisticated electronic
monitoring and protection of the oil pump electrical supply, ensuring long life and reliable
operation of the oil pump motor. Variable speed drive technology reduces oil pump power
consumption, running only at the speed required, rather than at full head with a pressure
regulating bypass valve.

Ensure the fastest chiller restarts with Quick Start feature
Temperature-sensitive operations such as data center,
pharmaceutical, and manufacturing facilities require constant
cooling for equipment and processes. If power fails and cooling
is interrupted, critical operations may also fail — risking millions
of dollars in equipment failure and operational downtime.
Now there‘s a sure way to reduce the risk of cooling disruption —
the Quick Start feature from Johnson Controls. This feature for
YORK® centrifugal chillers with OptiSpeed™ variable-speed drive
can save you both time and money by:
• Reducing time for chiller restart after power failure
• Rapidly re-establishing chilled-water temperature
• Keeping process equipment cooled
• Reducing risks of expensive downtime
• Providing a faster initial start, too
Reduce restart time to seconds
After power is interrupted, it can take a standard centrifugal
chiller many minutes to restart. But with the Quick Start feature,
once power is restored, the chiller can restart in as little as
25 seconds!
However, we understand that your application does not just
require the chiller to restart, but needs the fastest delivery of
chilled water at the design temperature. In Figures 1, 2, and 3
on the next page, restart times are measured from the moment
the power fails, and the backup generator is assumed to have
established emergency power in 15 seconds.

Faster restarts due to smarter power management
The Quick Start feature is available in two configurations,
for use with or without an uninterruptible power supply (UPS):
Quick Start feature without UPS is fast:
• Once emergency power is established, the chiller can restart as soon as the OptiView™ control panel reboots (75 seconds) and the OptiSpeed drive precharges (25 seconds), assuming coastdown of the compressor has been completed. If emergency power is available after 15 seconds, the chiller
will restart in 115 seconds after power was lost.
Quick Start feature with UPS is faster:
• The UPS keeps the OptiView and OptiSpeed control circuits energized and the oil heater operative until the emergency generator is activated, which eliminates the need for control panel reboot. The chiller will restart in 60 seconds after power was lost.
Faster restart restores specified leaving chilled-water
temperature quicker
The Quick Start feature not only minimizes chiller restart time, it reduces the time required for the re-establishment of the design leaving chilled-water temperature (LCHWT). The Quick Start feature utilizes accelerated loading logic, with the inlet vanes fully open, to re-establish the specified leaving chilled-water temperature faster. While the actual time to re-establish the LCHWT will depend on plant design, compressor size, and operating conditions, a chiller equipped with the Quick Start option can cut the time by as much as 70%.
