Introduction The YORK YS Chiller offers 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.
FORM 160.80-EG1 (511) Ratings Rated in accordance with the latest issue of AHRI Standard 550/590. AHRI CERTIFICATION PROGRAM The performance of YORK chillers is certified to the Air Conditioning and Refrigeration Institute (AHRI) complying with the certification sections of the latest issue of AHRI Standard 550/590. Under this Certification Program, chillers are regularly tested in strict compliance with this Standard. This provides an independent, third‑party verification of chiller performance.
OptiView Control Center OPTIVIEW CONTROL CENTER The YORK OptiView Control Center, furnished as standard on each chiller, provides the ultimate in efficiency, monitoring, data recording, chiller protection and operating ease. The control center is a factory mounted, wired, and tested state-of-the-art microprocessor based control system for R-134a screw chillers. The panel is configured with a 10.
OptiView Control Center - continued Setpoints can be changed from a remote location via 0-10VDC, 4-20mA, contact closures or through serial communications. The adjustable remote reset range [up to 20°F (11.1°C)] provides flexible, efficient use of remote signal depending on reset needs. Serial data interface to the Building Automation System (BAS) is through the General Protocol Interface Card (GPIC), which can be mounted inside the Control Center.

FORM 160.80-EG1 (511) Application Data The following is a user’s guide in the application and installation of Chillers, and will ensure the reliability and trouble-free life for which this equipment was designed. While this guide is directed towards normal, water-chilling applications, the Johnson Controls sales representatives can provide complete recommendations on other types of applications.
FORM 160.80-EG1 (511) include cooling condenser water using chilled water, wells, river or other low temperature fluids. For outdoor applications, please contact Large Tonnage Application Team. WATER CIRCUITS Flow Rate – For normal water chilling duty, evaporator flow rates are permitted at water velocity levels in the heat exchangers tubes of between 3 ft./second and 12 ft./second (0.91 m/s and 3.66 m/s). Condenser flow rates are permitted between 3.33 ft./sec. and 12 ft./sec. (1.01 m/s and 3.66 m/s).
FORM 160.80-EG1 (511) Application Data - continued MULTIPLE UNITS Selection – Many applications require multiple units to meet the total capacity requirements as well as to provide flexibility and some degree of protection against equipment shutdown. There are several common unit arrangements for this type of application. The Chiller has been designed to be readily adapted to the requirements of these various arrangements. Parallel Arrangement (Refer to Fig.
FORM 160.80-EG1 (511) overflow valves or type tested Safety Pressure switches or a combination of these devices. Sized to the requirements of applicable codes, a vent line must run from the relief device to the outside of the building. This refrigerant relief piping must include a cleanable, vertical-leg dirt trap to catch vent-stack condensation. Vent piping must be arranged to avoid imposing a strain on the relief connections and should include one flexible connection.
Application Data - continued conductors have proven to be unsatisfactory when connected to copper lugs. Aluminum oxide and the difference in thermal conductivity between copper and aluminum cannot guarantee the required tight connection over a long period of time. Power Factor Correction Capacitors – Capacitors can be applied to a chiller for the purpose of power factor correction. For remote-Mounted Electro-Mechanical Starters, the capacitors should be located on the load side of the starter.
