YORK YCWS Water-Cooled models provide chilled water for all air conditioning applications that
use central station air handling or terminal units. They are completely self-contained and are
designed for indoor (new or retrofit) installation. Each unit includes accessible semi-hermetic
screw compressors, a liquid cooler, water cooled condenser, and a user-friendly, diagnostic
Microcomputer Control Center all mounted on a rugged steel base. The units are produced at an
ISO 9001 registered facility. The YCWS chillers have certified ratings in accordance with ARI
Standard 550/590.
Introduction
York YCWS Water Cooled Screw Chillers

4YORK INTERNATIONAL
GENERAL
The Liquid Chiller will be completely assembled with all
interconnecting refrigerant piping and internal wiring,
ready for field installation.
Theunitwillbepressure-tested,evacuated,andcharged
with Refrigerant-22, and York ‘L’ (POE) synthetic oil.
There will be an operational test, with water flowing
through the cooler, to check that each control device
operates correctly.
The unit will be covered with a coat of Caribbean Blue
enamel. Units are designed in accordance with NFPA
70 (National Electric Code), U.L. and cU.L. Standards,
ASHRAE/ANSI 15 Safety Code for Mechanical Refrig-
eration. All units are produced at an ISO 9001 regis-
teredfacility. AllYCWS chillers are rated and certified in
accordance with ARI Standard 550/590 at ARI condi-
tions.
SEMI-HERMETIC YORK SCREW COMPRESSORS
• Continuousfunction,microprocessorcontrolled,3-way
proportionalCapacityControlValveprovidesregulated
output pressure independent of valve input pressure
for a stable, smooth, and precise match of compres-
sor capacity to cooling load to 10% of chiller capacity.
•Automatic spring return of capacity control valve to
minimum load position ensures compressor starting
at minimum motor load. Internal discharge check to
prevent rotor backspin upon shutdown.
•Acoustically tuned, internal discharge gas path elimi-
natesobjectionablenoise at the source,whileoptimiz-
ing flow for maximum performance.
• Reliable suction gas cooled, high efficiency, acces-
sible hermetic motor with APT2000 type magnet wire
and redundant overload protection using both ther-
mistor and current overload protection.
• Suction gas screen and serviceable, 0.5 micron full
flow oil filter within the compressor housing.
• Cast iron compressor housing precisely machined for
optimalclearances and superb efficiency.Entire com-
pressor,fromsuctionto discharge has a Design Work-
ing Pressure of 450psig (31 bar).
• 350W compressor body cartridge heater.
• Each compressor will be mounted on isolator pads to
reduce transmission of vibration to the rest of the unit.
COOLER
Thedual-circuit cooler willbe the direct-expansion type,
with refrigerant in the tubes and chilled liquid flowing
through the baffled shell. The design working pressure
of the shell (liquid) side will be 150 PSIG (10.3 bar), and
300 PSIG (26.7 bar) for the tube (refrigerant) side.
Thecooler will be constructed andtested in accordance
withthe applicable sections of theASME Pressure Ves-
sel Code, Section VlII, Division (1). The water side will
be exempt per paragraph U-1, (c)(6).
Thewater baffles willbe constructed ofgalvanized steel
to resist corrosion. The removable heads will allow ac-
cesstotheinternallyenhanced,seamless,coppertubes.
Vent and drain connections will be included.
The cooler will be covered with 3/4" (19.1 mm ) flexible,
closed-cell, foam insulation (K = 0.25).
CONDENSER
The condenser is a cleanable thru-tube type with steel
shell,coppertubes,removablewaterheads,andincludes
integral subcooling. Refer to PHYSICAL DATA for de-
sign working pressures. The shell will be constructed
and tested in accordance with section Vll, division 1 of
the ASME pressure-vessel code. The water side is ex-
empt per paragraph U-1 (c) of section VlII, division 1 of
the ASME pressure-vessel code. The condenser is
equipped with relief valves and will hold the full refriger-
ant charge for pumpdown.
REFRIGERANT CIRCUIT
Twoindependent refrigerant circuits willbe furnished on
each unit. All piping will be copper with brazed joints.
The liquid line will include: a shutoff valve with charging
port; sightglass with moisture indicator; thermal expan-
sion valve; solenoid valve; and high-absorption remov-
able-core filter drier. The entire suction line and the liq-
uid line between the expansion valve and the cooler will
be insulated with flexible, closed-cell, foam insulation.
POWER AND CONTROL PANELS
All controls and motor starting equipment necessary for
unitoperation shall befactory wired and functiontested.
The panel enclosures shall be designed to NEMA 1 (IP
32) and manufactured from powder-painted galvanized
steel.

Completewater chillingcapacityratingsforYORK YCWS
chillers are shown on the following pages to cover the
majority of job requirements. For any application be-
yond the scope of this Engineering Guide, consult your
nearest YORK Office.
SELECTION RULES
1. RATINGS- YCWS 200, 230380, 460 & 575-3-60rat-
ingarecertified in accordance withARIstandard550/

dardARI conditions arerated in accordancewith ARI
ratingprocedures. Theseratingsmay be interpolated
but should not be extrapolated.
2. COOLING WATER QUANTITY - Ratings are based
on 10ºF chilled water range. Use the chilled water
correction factors (below) for other ranges except as
limitedbywaterpressuredrop,minimum or maximum
water flows for the cooler.
3. CONDENSER WATER QUANTITY – Rating are ap-
plicable from 2 to 4 gpm/ton as limited by water pres-
sure drop or minimum or maximum water flows for
the condenser. Using the tabulated MBH, the Cond.
GPM is calculated as follows:
Cond. GPM = MBH x 2
Cond. Water Range (ºF)
4. FOULING FACTORS – Rating are based on 0.0001

other fouling factors, consult the table below or con-
tact your YORK representative.

METHOD OF SELECTION
If the duty requires a 10ºF range on both the cooler and
condenser, see “Ratings”. For water ranges other than
10ºF, use the following procedure.
1. Determine capacity required from the following for-
mula
GPM x Chilled Water Range (ºF)
Capacity (tons) = 24
2. After applying any fouling factor corrections, the ac-
tual condenser heat rejection may be determined as
follows:
Heat Rejection (Btuh) = (Tons x 12,000) + (kW x 3415)
Heat Rejection (Btuh)
Heat Rejection (MBH) = 1000
= (Tons x 12) = (kW x 3.415)
3. Determine condensing water requirements for water
cooled models as follows:
Heat Rejection (MBH) x 1000
Condenser Tons = 15,000
Condenser Tons x 30
Cond. Water GPM = Condenser Water Range (ºF)
Or combine the two formulas:

2. From the rating, a model YCWS0120SC has a ca-
pacity range required. For the cooler leaving water
temperature of 44ºF and a condenser leaving water
temperature of 95ºF, the unit capacity rating table in-
dicates:
Tons = 110.3
KW = 86.2
EER = 15.4
Correctingforthe12ºFchilled waterrangeandthe 0.0005
condenser-foulingfactor:
Tons = 110.3 x 1.0133 x 0.9961 = 111.3TR
KW = 86.2 x 0.9993 x 1.0065 = 86.7
The unit is suitable.
3. Determine the average full load kW and EER at 95.0
Tons
95.0 X (86.7) = 74KW
111.3
Tons x 12 = 95.0 X 12 = 15.4
EER = Kw 74
4. Determine the cond. Heat rejection as follows:
Heat Rejection (MBH) = (Tons x 12) + (kW x 3.415)
= (95.0 x 12) + (74 x 3.415)
= 1140 + 253
= 1393
5. Determine GPM condensing water as follows:
GPM Condenser Water = MBH x2
Cond Water Range
