YK - ALL MODELS
INTRODUCTION

YORK YK Chillers 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…
RATINGS

COMPUTERIZED PERFORMANCE RATINGS TAKE ADVANTAGE OF COLDER COOLING TOWER WATER TEMPERATURES Each chiller is custom-matched to meet the individual building load and energy requirements. A variety of standard heat exchangers and pass arrangements are available to provide the best possible match. YORK…
OPTIVIEW CONTROL CENTER

for specific operations are provided for on many of YK OPTIVIEW CONTROL CENTER the screens. The panel verbiage is available in eight languages as standard and can be changed on the fly without having to turn off the chiller. Data can be displayed in either English or Metric units plus keypad entry…
This printed circuit board requests the required data

from the microboard and makes it available for the Johnson Controls Metasys® network. This optional board is available through the Johnson Controls Building Efficiency group. The operating program is stored in non-volatile memory (EPROM) to eliminate chiller failure due to AC power failure/battery…
The SCHEDULE screen contains more programmable

values than a normal display screen. Each programmable value is not linked to a specific button; instead the select key is used to enable the cursor arrows and check key to program the Start/Stop times for any day of the week up to 6 weeks in advance. The user has the ability to define a standard…
MECHANICAL SPECIFICATIONS

GENERAL The YORK YK Centrifugal Liquid Chillers are completely factory-packaged including the evaporator, condenser, compressor, motor, lubrication system, control center, and all interconnecting unit piping and wiring. The initial charge of refrigerant and oil is supplied for each chiller. When the…
Tubes

REFRIGERANT FLOW CONTROL Heat exchanger tubes are state-of-the-art, highefficiency, externally and internally enhanced type to provide optimum performance. Tubes in both the evaporator and condenser are 19 mm O.D. standard or 25.4 mm optional in some shells] copper alloy and utilize the “skip-fin”…

ACCESSORIES AND MODIFICATIONS

OPTISPEED DRIVE A 400V – 3-Ph – 50Hz variable speed drive is factorypackaged and mounted on the YORK YK chiller. It is designed to vary the compressor motor speed by controlling the frequency and voltage of the electrical power to the motor. The adaptive capacity control logic automatically adjusts…
SPRING ISOLATION MOUNTING

HIGH AMBIENT TEMPERATURE Spring isolation mounting is available instead of standard isolation mounting pads when desired. Four level-adjusting, spring-type vibration isolator assemblies with non-skid pads are provided for fieldinstallation. Isolators are designed for 25 mm deflection. Chiller…
APPLICATION DATA

The following discussion is a user’s guide in the application and installation of YK chillers to ensure the reliable, trouble free life for which this equipment was designed. While this guide is directed towards normal, water chilling applications, the Johnson Controls sales representative can…

Chilled Water – A water strainer of maximum 3.2 mm

perforated holes must be field-installed in the chilled water inlet line as close as possible to the chiller. If located close enough to the chiller, the chilled water pump may be protected by the same strainer. The strainer is important to protect the chiller from debris or objects which could…
MULTIPLE UNITS

HEAT RECOVERY 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 YK chiller has been…
REFRIGERANT RELIEF PIPING

Each chiller is equipped with dual pressure relief valves on the condenser and two dual relief valves on the evaporator, or two single relief valves on the evaporator if the optional refrigerant isolation valves are ordered. The dual relief valves on the condenser are redundant and allow changing of…
