YORK YCRL Remote Condenser Liquid Chillers provide chilled water for all air condition-
ing applications that use central station air handling or terminal units. They are self-con-
tained and are designed for indoor (new or retrofit) installation. Each unit includes hermet-
ic scroll compressors, a liquid evaporator, and a user-friendly, diagnostic Microcomputer
Control Center all mounted on a rugged steel base. Remote condensers (model VDC) are
available separately from Johnson Controls. The units are produced at an ISO 9001 reg-
istered facility. The YCRL chillers are rated in accordance with AHRI Standard 550/590.
GENERAL
The chiller will be completely assembled with all interconnecting refrigerant piping and
internal wiring, ready for field connection to a remote condenser.
The unit will be pressure-tested, evacuated, and charged with a nitrogen holding charge,
and York ‘V’ (POE) synthetic oil.
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 reg-
istered facility. All YCRL condensing units are rated in accordance with AHRI Standard
550/590 at AHRI conditions.
COMPRESSORS
The chiller has suction-gas cooled, hermetic, scroll compressors. The YCRL’s 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 and oil reservoir
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 transmission of vibration to the rest of the unit.

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 evapora-
tor shell. Low-pressure vapor enters the compressor where pressure and superheat are
increased. High-pressure vapor is passed through a remote condenser where heat is
rejected to the air flow passing through the coil. 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.

GUIDE TO SELECTION
Complete water chilling capacity ratings for YORK YCRL condensing units are shown on
the following pages to cover the majority of job requirements. For any application beyond
the scope of this Engineering Guide, consult your nearest Johnson Controls office.
SELECTION RULES
1. Ratings - All YCRL ratings are in accordance with AHRI Standard 550/590, at the AHRI
standard condi tions. Ratings not at standard AHRI conditions are rated in accordance
with AHRI rating procedures. These ratings may be interpolated but extrapolated.
2. Cooling Water Quantity - Ratings are based on 10ºF chilled water range with the
evaporator at sea level. Use the chilled water correction factors (below) for other
ranges except as limited by water pressure drop, minimum or maximum water ows
for the evaporator.
3. Fouling Factors – Ratings are based on 0.0001 evaporator fouling factor. For other
fouling factors, consult the table below or contact your Johnson Controls represen-
tative.

METHOD OF SELECTION
If the duty requires a 10ºF (6°C) range on the evaporator, see “Ratings”. For water ranges
other than 10ºF (6°C), use the following procedure. Line sizes can be determined by re-
viewing York DX Piping Guide 050.40-ES2.
1. Determine capacity required from the following formula:
Capacity (Tons) =
GPM x Chilled Water Range (°F)
24
2. After applying any fouling factor corrections, the actual condenser heat rejection
may be determined as follows:
Heat Rejection (MBH) =
Heat Rejection (Btuh)
1000
= (Tons x 12) = (kW x 3.415)
3. Size condenser using manufacturer’s recommendations.
SAMPLE SELECTION
Water Cooled Chiller (YCRL)
GIVEN – Chill 200 GPM of water from 56ºF to 44ºF and 0.0001 evaporator fouling factor
with 125°F saturated discharge temperature.
FIND – The required unit size capacity, kW, EER, and water pressure drop, and the con-
denser MBH heat rejection.
SOLUTION:
1. Chilled water range = 56ºF - 44ºF = 12ºF and correction factors are 1.009 for Tons
and 1.001 for kW for the evaporator.
Capacity (Tons) =
GPM x Chilled Water Range (°F)
24
=
200 x 12
= 100TR
24
2. From the rating, a model YCRL0118HE has a capacity range required. For the
evaporator leaving water temperature of 44ºF and a saturated discharge tempera-
ture of 125°F, the unit capacity rating table indicates:
Tons = 101.7
KW = 110.0
EER = 11.1
Correcting for the 12ºF chilled water range:
Tons = 101.7 x 1.009 = 102.6 TR
KW = 110.0 x 1.001 = 110.1 kW

3. Determine the average full load kW and EER at 100 Tons
100
x (110.1) = 107.3
102.6
EER =
Tons x 12
=
100 x 12
= 112
kW 107.3
4. Determine the condensing Heat rejection as follows:
Heat Rejection (MBH) = (Tons x 12) + (kW x 3.415)
= (102.6 x 12) + (110.1 x 3.415)
= 1231.2 + 376.0
= 1607.2
5. From "Pressure Drop Curves" on page 17, locate the pressure drops with 200 GPM
through the evaporator of the Model YCRL118HE:
Evaporator Pressure Drop at 200 GPM = 8 ft
The unit is suitable.

REFRIGERANT PIPING
General – When the unit has been located in its final position, the unit piping may be con-
nected. Normal installation precautions should be observed in order to receive maximum
operating efficiencies. System piping should conform to the York DX Piping Guide form
050.40-ES2 or ASHRAE refrigeration handbook guidelines. All piping design and instal-
lation is the responsibility of the user.
JOHNSON CONTROLS ASSUMES NO WARRANTY RESPONSIBILITY FOR SYSTEM
OPERATION OR FAILURES DUE TO IMPROPER PIPING OR PIPING DESIGN.
All filter driers, sight glasses, expansion valves and liquid line solenoid valves are fac-
tory installed on each refrigerant circuit. Interconnecting refrigerant piping and refrigerant
charge are supplied and installed by others.

REFRIGERANT LINE SIZING
Refrigerant piping systems must be designed to provide practical line sizes without exces-
sive pressure drops, prevent compressor oil from being “trapped” in the refrigerant piping,
and ensure proper flow of liquid refrigerant to the thermal expansion valve. Be sure to
review form 050.40-ES2. Considerations should be given to:
1. Discharge line pressure drop due to refrigerant ow.
2. Discharge line refrigerant velocity for oil return.
3. Liquid line pressure drop due to refrigerant ow.
4. Liquid line pressure drop (or gain) due to vertical rise of the liquid line.
To ensure a solid column of liquid refrigerant to the expansion valve, the total liquid line
pressure drop should never exceed 40 PSIG (2.8 barg). Refrigerant vapor in the liquid line
will measurably reduce valve capacity and poor system performance can be expected.
To allow adequate oil return to the compressor, discharge risers should be sized for a
minimum of 1000 FPM (5.08 m/s) while the system is operating at minimum capacity to
ensure oil return up the suction riser.
FORM 150.27-EG1 (1115)
JOHNSON CONTROLS

Selection Data (Cont'd)
Chiller Below Condenser – On a system where the chiller is located below the condens-
er, the discharge line must be sized for both pressure drop and oil return. In some cases
a double discharge riser must be installed to ensure reliable oil return at reduced loads.
Condenser Below Chiller – When the condenser is located below the chiller, the liquid
line must be designed for both friction loss and static head loss due the vertical rise. The
value of static head loss of 5 PSI/ft. (3.4 kPa/30 cm) must be added to the friction loss
pressure drop in addition to all pressure drops due to driers, valves, etc.
OIL TRAPS
All horizontal discharge lines should be pitched at least 1/4” per foot (2 cm/m) in the direc-
tion of the refrigerant flow to aid in the return of oil to the chiller. All discharge lines with
a vertical rise exceeding 3 feet (.91 meters) should have a “P” trap at the bottom and top
of the riser. Discharge lines with a vertical rise exceeding 25 feet (7.6 meters) should be
trapped every 15 feet (4.6 meters).
REFRIGERANT CHARGE
The chiller is charged and shipped with a dry nitrogen holding charge. The operating
charge for the chiller, remote condenser and refrigerant piping must be weighed in after all
refrigerant piping is installed, leak checked, and evacuated. Final adjustment of refriger-
ant charge should be verified by subcooling values (refer to IOM section on Pre-Startup
for checking subcooling).
