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)

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)

200 x 12

= 100TR

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).
