Equipment Overview
YORK YCWL Water-Cooled chillers provide chilled water for all air conditioning applica-
tions 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
hermetic scroll compressors, a liquid evaporator, water cooled condenser, and a user-
friendly, Microcomputer Control Center mounted on a rugged steel base. The units are
produced at an ISO 9001 registered facility. The YCWL chillers are rated in accordance
with ARI Standard 550/590.
The chiller will be completely assembled with all interconnecting refrigerant piping and
internal wiring, ready for field installation.
The unit will be pressure-tested, evacuated, and charged with Refrigerant-410A, and York
‘V’ (POE) synthetic oil. There will be an operational test, with water flowing through the
evaporator, to check that each control device operates correctly.
The unit can be covered with an optional overspray coat of Caribbean Blue enamel. Units
are designed in accordance with NFPA 70 (National Electric Code), ASHRAE/ANSI 15
Safety Code for Mechanical Refrigeration. All units are produced at an ISO 9001 regis-
tered facility. All YCWL chillers are rated in accordance with ARI Standard 550/590 at ARI
conditions.
COMPRESSORS
The chiller has suction-gas cooled, hermetic, scroll compressors. The YCWL compres-
sors incorporate a compliant scroll design in both the axial and radial direction. All rotating
parts are statically and dynamically balanced. A large internal volume provides greater
liquid tolerance. Compressor crankcase heaters are also included for extra protection
against liquid migration. All compressors are mounted on isolator pads to reduce trans-
mission of vibration to the rest of the unit.
EVAPORATOR
The dual-circuit evaporator will be 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 400 PSIG (27.6 bar) for the tube (re-
frigerant) side.
The evaporator will be constructed and tested in accordance with the applicable sections
of the ASME Pressure Vessel Code, Section VlII, Division (1). The water side will be ex-
empt per paragraph U-1, (C), (6).
The removable heads will allow access to the internally enhanced, seamless, copper
tubes. Vent and drain connections will be included. Nozzle connections are grooved to
accept ANSI/AWWA C-606 couplings.
The evaporator will be covered with 3/4” (19.1 mm) flexible, closed-cell, foam insulation
(K = 0.25).

Accessories and Options
All accessories and options are factory installed unless otherwise noted.
POWER OPTIONS
Single Point Supply Terminal Block - The standard power wiring connection on all mod-
els is a single point power connection to a factory provided terminal block. Components
included are the enclosure, terminal-block and interconnecting wiring to the compressors.
Separate external protection must be supplied, by others, in the incoming power wiring.
(Do not include this option if either the Single-Point Non-Fused Disconnect Switch or
Single-Point Circuit Breaker options have been included.)
Single Point Non-Fused Disconnect Switch - An optional unit-mounted disconnect switch
with external, lockable handle (in compliance with Article 440-14 of N.E.C.), can be supplied
to isolate the unit power voltage for servicing. Separate external fusing must be supplied,
by others in the power wiring, which must comply with the National Electrical Code and/or
local codes.
Single Point Circuit Breaker - An optional unit mounted circuit breaker with external, lock-
able handle (in compliance with N.E.C. Article 440-14), can be supplied to isolate the power
voltage for servicing.
Multiple Point Circuit Breaker – Optional multiple point supply with independent system
circuit breakers and locking external handles (in compliance with Article 440-14 of N.E.C)
can be factory supplied. Selecting this option also selects optional compressor external
overloads, for reduced MCA.
Control Transformer – Converts unit power voltage to 115-1-60 (0.5 or 1.0 KVA capacity).
Factory mounting includes primary and secondary wiring between the transformer and the
control panel.
Compressor External Overloads – Optional compressor motor overloads can be factory
mounted in the unit control/power panel. This option will reduce the chiller MCA (minimum
circuit ampacity) and allow for reduced wire sizing to the unit. This option is not available
for applications with Leaving Condenser Water Temperature (LCWT) greater than 110ºF
(43ºC).
CONTROLS OPTIONS
Language LCD And Keypad - Standard display language and keypad is in English. Span-
ish, French, German, and Italian are available as an option.

proof SPDT, NEMA 3R switch, 150 PSIG (10.3 bar) DWP, 20°F to 250°F (-29°C to 121°C)
with 1” NPT (IPS) connection for upright mounting in horizontal pipe. The flow switch or its
equivalent must be furnished with each unit. (Field mounted)
JOHNSON CONTROLS 11
FORM 150.26-EG1 (715)
Accessories and Options (Cont'd)
Differential Pressure Switch - An alternative option to the paddle-type flow switch. 3-45
PSIG (0.2-3 bar) range with ¼” NPTE pressure connections. (Field Mounted)
Pressure Vessel Codes - Evaporators and condensers are be supplied (Standard) in con-
formance with the A.S.M.E. pressure codes.
Flanges (ANSI/AWWA C-606 Couplings Type) – consists of flange adapters for grooved
end pipe on evaporator and condenser (note: the 0064HE and 0094SE units do not
include evaporator flanges, and the 0056SE, 0064SE, and 0074SE units do not include
condenser flanges). Standard 150 psi (10.3 bar). (Field-mounted, matching pipe
flange by contractor).
Double Thick Insulation – Double Thick (1-1/2”) insulation provided on the evaporator.
CHILLER OPTIONS
Final Paint Overspray - Overspray painting of unit after assembly. (Factory Paint)
Service Isolation Valve - Service suction isolation valve added to unit per system in addi-
tion to the standard discharge service valve.
Hot Gas By-Pass – Permits continuous, stable operation at capacities below the mini-
mum step of compressor unloading to as low as 5% capacity (depending on both the unit
and operating conditions) by introducing an artificial load on the evaporator. Hot gas by-
pass is installed on only refrigerant system #2 on two-circuited units.
Chicago Code Relief Valves – Unit will be provided with relief valves to meet Chicago code
requirements.
Compressor Acoustic Sound Blanket – Each compressor is individually enclosed by
an acoustic sound blanket. The sound blankets are made with one layer of acoustical
absorbent textile fiber of 5/8” (15mm) thickness; one layer of anti-vibrating heavy mate-
rial thickness of 1/8” (3mm). Both are closed by two sheets of welded PVC, reinforced for
temperature and UV resistance.
Non Reversing Heat Pump – Unit configured for optional operating mode controlled by
leaving condenser water temperature. Temperature setpoint user adjustable from 86°F –
122°F (30°C – 50°C), default 122°F (50°C). While operating in this mode, chiller will stage
compressors to maintain heating setpoint provided there is sufficient cooling demand.
Unit can be changed from heat pump to chiller mode locally or through BAS. Unit leav-
ing evaporator water temperature will float based on heating output while in this mode,
making this option ideal for applications that do not require a constant evaporator leaving
temperature or for multiple (series) chiller installations. Option requires factory startup
and adds one day startup labor for field configuration. Requires evaporator leaving tem-
perature above 40°F (4°C) while heat pump is in operation.

Refrigerant Flow Diagram
Low-pressure liquid refrigerant enters the evaporator tubes and is evaporated and super-
heated by the heat energy absorbed from the chilled liquid passing through the evaporator
shell. Low-pressure vapor enters the compressor where pressure and superheat are in-
creased. High-pressure vapor is passed through the condenser where heat is rejected to
the condenser water passing through the tubes. The fully condensed and subcooled liquid
leaves the condenser and enters the expansion valve, where pressure reduction and fur-
ther cooling take place. The low pressure liquid refrigerant then returns to the evaporator.

METHOD OF SELECTION
If the duty requires a 10ºF range on both the evaporator and condenser, see “Ratings”.
For water ranges other than 10ºF, use the following procedure.
1. Determine capacity required from the following formula.
GPM x Chilled Water Range (ºF)
Capacity (Tons) =
24
2. After applying any fouling factor corrections, the actual condenser heat rejection
may be determined as follows:
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

SAMPLE SELECTION
Water Cooled Chiller (YCWL)
GIVEN – Chill 200 GPM of water from 56ºF to 44ºF and 0.0001 evaporator fouling factor
with 85ºF to 95ºF condensing water available. The fouling factor is 0.0005 for the con-
denser.
FIND – The required unit size capacity, kW, EER, and water pressure drop.
SOLUTION:
1. Chilled water range = 56ºF - 44ºF = 12ºF and correction factors are 1.009 for Tons
and 1.001 for kW for the evaporator.
GPM x Chilled Water Range
Capacity (Tons) =
24
200 x 12
= = 100TR
24
2. From the rating, a model YCWL01180SE has a capacity range required. For the
evaporator leaving water temperature of 44ºF and a condenser leaving water tem-
perature of 95ºF, the unit capacity rating table indicates:
Tons = 108.4
KW = 83.5
EER = 15.6
Correcting for the 12ºF chilled water range and the 0.0005 condenser-fouling fac
tor (Correction factors for the condenser are 0.995 for Tons and 1.010 for kW):
Tons = 108.4 x 1.009 x 0.995 = 108.8TR
KW = 83.5 x 1.001 x 1.010 = 84.4 kW
3. Determine the average full load kW and EER at 100 Tons.

4. Determine the cond. Heat rejection as follows:
Heat Rejection (MBH) = (Tons x 12) + (kW x 3.415)
= (108.8 x 12) + (84.4 x 3.415)

6. From curves on pages 14 and 15, the pressure drops with 200 GPM through the
evaporator and 319 GPM through the condenser of the Model YCWL118SE:
Evaporator Pressure Drop at 200 GPM = 9 ft
Condenser Pressure Drop at 319 GPM = 18 ft
The unit is suitable.
