potential, if misused or handled improperly, to cause

bodily injury or death. It is the obligation and respon-

sibility of operating/service personnel to identify and

recognize these inherent hazards, protect themselves,

and proceed safely in completing their tasks. Failure

to comply with any of these requirements could result

in serious damage to the equipment and the property in

FORM 160.54-O1

JOHNSON CONTROLS

When the compressor motor is driven by a YORK Solid

State Starter, one of three different Starters could be ap-

plied. Later production chillers are equipped with either

the Style B Liquid Cooled Solid State Starter (LCSSS)

or the Medium Voltage Solid State Starter (MVSSS).

Earlier vintage chillers are equipped with the Mod “A”

Solid State Starter. This starter contains a Trigger Board

that interfaces to a Logic Board that is installed inside of

the Control Center.

When the compressor motor is driven by a YORK Vari-

able Speed Drive, there could be a Variable Speed Drive

(VSD) or a Medium Voltage Variable Speed Drive (MV

VSD) applied.

In operation, a liquid (water or brine to be chilled) ows

through the cooler, where boiling refrigerant absorbs heat

from the liquid. The chilled liquid is then piped to fan

coil units or other air conditioning terminal units, where

it ows through nned coils, absorbing heat from the

air. The warmed liquid is then returned to the chiller to

complete the chilled liquid circuit.

SYSTEM OPERATION DESCRIPTION (SEE FIG. 2)

The YORK Model YK MaxE™ Chiller is commonly ap-

plied to large air conditioning systems, but may be used on

other applications. The chiller consists of an open motor

mounted to a compressor (with integral speed increasing

gears), condenser, evaporator and variable ow control.

The chiller is controlled by a modern state of the art Mi-

crocomputer Control Center that monitors its operation.

The Control Center is programmed by the operator to suit

job specications. Automatic timed start-ups and shut-

downs are also programmable to suit nighttime, week-

ends, and holidays. The operating status, temperatures,

pressures, and other information pertinent to operation

of the chiller are automatically displayed and read on

a graphic display. Other displays can be observed by

pressing the keys as labeled on the Control Center. The

chiller with the OptiView Control Center is applied with

an electro-mechanical starter, YORK Solid State Starter

(optional), or Variable Speed Drive (optional).

JOHNSON CONTROLS

FORM 160.54-O1

The refrigerant vapor, which is produced by the boiling

action in the cooler, ows to the compressor where the

rotating impeller increases its pressure and temperature

and discharges it into the condenser. Water owing

through the condenser tubes absorbs heat from the refrig-

erant vapor, causing it to condense. The condenser water

is supplied to the chiller from an external source, usu-

ally a cooling tower. The condensed refrigerant drains

from the condenser into the liquid return line, where the

variable orice meters the ow of liquid refrigerant to the

cooler to complete the refrigerant circuit.

The major components of a chiller are selected to handle

the refrigerant, which would be evaporated at full load

design conditions. However, most systems will be called

upon to deliver full load capacity for only a relatively

small part of the time the unit is in operation.

7619A(D)

DETAIL A – COMPRESSOR PREROTATION VANES

CAPACITY CONTROL

The major components of a chiller are selected for full

load capacities, therefore capacity must be controlled

to maintain a constant chilled liquid temperature leav-

ing the cooler. Prerotation vanes (PRV), located at the

entrance to the compressor impeller, compensate for

variation in load (See Detail A).

The position of these vanes is automatically controlled

through a lever arm attached to an electric motor located

outside the compressor housing. The automatic adjust-

ment of the vane position in effect provides the perfor-

mance of many different compressors to match various

load conditions from full load with vanes wide open to

minimum load with vanes completely closed.
