GENERAL
The 80-160 Ton (273 - 560 kW) QCC3 Condensing Unit Models are shipped complete
from the factory ready for field installation.
The unit is pressure-tested, evacuated and given a nitrogen holding charge and includes
an initial oil charge (R-410A refrigerant supplied by others). After assembly, a operational
test is performed to assure that each control device operates correctly.
The unit structure is heavy-gauge, galvanized steel. This galvanized steel is coated with
baked-on powder paint, which, when subjected to ASTM B117 1000 hour, salt spray test-
ing, yields a minimum ASTM 1654 rating of “6”. Units are designed in accordance with
NFPA 70 (National Electric Code), ASHRAE/ANSI 15 Safety code for mechanical refrig-
eration, and are cETL listed. All units are produced at an ISO 9000-registered facility.
COMPRESSORS
The chiller has suction-gas cooled, hermetic, scroll compressors. The compressors in-
corporate a compliant scroll design in both the axial and radial direction. All rotating parts
of the compressors 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.
CONDENSER
Coils – Fin and tube condenser coils of seamless, internally-enhanced, corrosion resis-
tant copper tubes are arranged in staggered rows, mechanically expanded into aluminum
fins. Integral subcooling is included. The design working pressure of the coil is 650 psig
(45 barg).
Fans – The condenser fans are composed of corrosion-resistant aluminum hub and glass-
fiber-reinforced polypropylene composite blades molded into a low noise airfoil section.
The are designed for maximum efficiency and are statically and dynamically balanced for
vibration free operation. They are directly driven by independent motors, and positioned
for vertical air discharge. The fan guards are constructed of heavy-gauge, rust-resistant,
coated steel. All blades are statically and dynamically balanced for vibration-free opera-
tion.
Motors – The fan motors are Totally Enclosed Air-Over, squirrel-cage type, current pro-
tected. They feature ball bearings that are double-sealed and permanently lubricated.
REFRIGERANT CIRCUIT
Two independent refrigerant circuits will be furnished on each unit. All unit piping will be
copper, with brazed joints. The liquid line will include a field connection shutoff valve with
charging port located on each condenser circuit. Suction line connections are provided on
each refrigeration circuit. A filter drier and sight glass are shipped loose for field installation
on each refrigerant circuit.
All expansion valves, liquid line solenoid valves, refrigerant, and refrigerant field piping
are supplied by others.

Accessories and Options
All options are factory installed unless otherwise noted.
COMPRESSOR AND PIPING OPTIONS:
Chicago Code Relief Valves – Unit will be provided with relief valves to meet Chicago
code requirements.
Hot Gas By-Pass – Permits continuous, stable operation at capacities below the mini-
mum step of compressor by unloading to as low as 5% capacity (depending on both the
unit and operating conditions). This is accomplished by introducing an artificial load. Hot
gas by-pass is available installed on refrigerant system #1 or on both systems of two cir-
cuited units..
Service Isolation Valve – Service suction and discharge (ball-type) isolation valves are
added to unit per system. This option also includes a system high pressure relief valve in
compliance with ASHRAE 15.
CONDENSER AND CABINET OPTIONS:
Condenser coil protection against corrosive environments is available by choosing any of
the following options. For additional application recommendations, refer to FORM 150.12-
ES1.
Pre-Coated Fin Condenser Coils – The condenser coils are constructed of black epoxy-
coated aluminum fins. This can provide corrosion resistance comparable to copper-fin
coils in typical seashore locations. Either these or the post-coated coils (below), are rec-
ommended for units being installed at the seashore or where salt spray may hit the unit.
Post-Coated Dipped Condenser Coils – The unit is built with dipped and cured con-
denser coils. This is another choice for seashore and other corrosive applications (with
the exception of strong alkalies, oxidizers and wet bromine, chlorine and fluorine in con-
centrations greater than 100 ppm).
Copper-Fin Condenser Coils – The unit constructed with condenser coils which have
copper fins. (This is not recommended for units in areas where they may be exposed to
acid rain).
Enclosure Panels (Unit) – Tamperproof Enclosure Panels prevent unauthorized access
to units. Enclosure Panels can provide an aesthetically pleasing alternative to expensive
fencing. Additionally, for proper head pressure control, Quantech recommends the use of
Condenser Louvered Panels for winter applications where wind gusts may exceed five
mph (eight km/h).
The following types of enclosure panels are available:
Wire Panels (Full Unit) – Consists of welded-wiremesh guards mounted on the exterior
of the unit. Prevents unauthorized access, yet provides free air flow.
Wire/Louvered Panels – Consists of welded-wire-mesh panels on the bottom part of unit
and louvered panels on the condenser section of the unit.

FORM QCC3-EG1 (517)
QUANTECH 11
Louvered Panels (Condenser Coil Only) – Louvered panels are mounted on the sides
and ends of the condenser coils for protection.
Louvered Panels (Full Unit) – Louvered panels surround the front, back, and sides of
the unit. These prevent unauthorized access and visually screen unit components. Unre-
stricted air flow is permitted through generously sized louvered openings. This option is
applicable for any outdoor design ambient temperature up to 115°F (46°C).
Sound Attenuation – One or both of the following sound attenuation options are recom-
mended for residential or other similar sound sensitive locations:
Compressor Acoustic Sound Blanket – Each compressor is individually enclosed by an
acoustic sound blanket. The sound blankets are made with one layer of acoustical absor-
bent textile fiber of 5/8” (15mm) thickness and one layer of anti-vibrating heavy material
thickness of 1/8” (3mm). Both are closed by two sheets of welded PVC, reinforced for
temperature and UV resistance.
Ultra Quiet Fans – Lower RPM, 8-pole fan motors are used with steeper-pitch fans.
Vibration Isolators – Level adjusting, spring type 1” (25.4mm) or seismic deflection or
neoprene pad isolators for mounting under unit base rails.
CONTROL OPTIONS:
Ambient Kit (Low) –Units will operate to 32°F (-4°C) (standard). This accessory includes
all necessary components to permit condensing unit operation to 0°F (-18°C). (This op-
tion includes the Discharge Pressure Transducer / Readout Capability option.) For proper
head pressure control in applications below 25°F (-4°C) where wind gusts may exceed
five mph (eight km/h), it is recommended that Optional Condenser Louvered Enclosure
Panels also be included.
Building Automation System Interface – The factory addition of a Printed Circuit Board
to accept a 4-20 milliamp, 0-10VDC or contact closure input to reset the discharge air tem-
perature from a Building Automation System. (The standard control panel can be directly
connected to a Quantech Building Automated System via the standard on board RS485
communication port.)
Language LCD And Keypad Display – Spanish, French, German, and Italian unit LCD
controls and keypad display available. Standard language is English.
Discharge Pressure Transducers And Readout Capability – the addition of pressure
transducers allows models to sense and display discharge pressure. (This option as in-
cluded with either the low or high ambient kits).
Suction Pressure Transducers And Readout Capability – The addition of suction
transducers allows models to sense and display suction pressure.
Suction Temperature Readout – The addition of temperature sensors allow models to
sense and display suction temperature.
Motor Current Module – Capable of monitoring compressor motor current. Provides
extra protection against compressor reverse rotation, phase-loss and phase imbalance.

Selection Data
The ratings shown on pages 18 through 24 are based on unit operation in a well designed
and properly piped system.
SELECTION RULES
1. Capabilities are based on Refrigerant R-410A.
2. Ratings may interpolated, but must not be extrapolated.
3. Ratings shown are at saturated suction temperatures corresponding to pressures
at the compressor. In actual practice, suction line pressure drop has the effect of
reducing compressor capacity, forcing the compressor to operate at a lower suction
pressure to maintain the desired evaporator temperature.
For normal air conditioning applications, size the suction line for a pressure drop of 3 PSI,
corresponding to 2°F, for R-410A refrigerant. Thus, the evaporator temperature will be ap-
proximately 2°F higher than the compressor suction temperature. Line loss must be taken
into consideration when selecting the evaporator.
SELECTION PROCEDURE
The air-cooled condensing unit may be selected from the Ratings on pages 12 through
17, if the ambient air temperature at the condenser and the saturated suction temperature
at the compressor are known. The ambient air temperature is a known design parameter,
but the suction temperature at the compressor, in many cases, is known only within cer-
tain allowable limits. The actual compressor operating suction temperature and the overall
performance of the system will depend directly upon the choice of the evaporator. Starting
with a preliminary evaporator selection at a nominal evaporator temperature and using
data supplied by the evaporator manufacturer, enter the ratings tables and select a unit to
meet the required cooling load at a suction temperature at least 2°F below the evaporator
temperature. The 2°F allows for normal suction line loss.
If more accurate selection is required, the evaporator capacity should be plotted against
the condensing unit capacity to determine the balanced system performance. Again, it is
necessary to factor in the suction line loss.
After the system balance point has been determined, the compressor KW input may be
interpolated from the ratings tables.

SAMPLE SELECTION
Select an R-410A Air-Cooled Condensing Unit with a matched central station air handling
unit having the following operating conditions:
DESIGN CONDITIONS
1. An air handling unit with four large DX coils (two per circuit) having a total cooling
load of 100 MBH (83 tons).
2. The coil suction temperature required 45°F.
3. The design outdoor ambient temperature is 95°F.
4. The power supply is 460V/3∅/60 hz.
Selection
1. Enter the QCC3080CZE Rating Table (page 12).
2. The model QCC3080CZE will provide 84.1 tons with 73.5 compressor KW input at
95°C ambient air and 45°F suction pressure.
3. CalculatethecompressorKwinputforthespecicdesignconditionsof148Kwand
35°C ambient air.
Kw = 83 x 73.5Kw = 72.5Kw
84.1Kw
The QCC3080CZE is the suitable selection for the design capacity.
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 installa-
tion is the responsibility of the user.
QUANTECH ASSUMES NO WARRANTY RESPONSIBILITY FOR SYSTEM
OPERATION OR FAILURES DUE TO IMPROPER PIPING OR PIPING DESIGN.
Filter driers and sight glasses are shipped loose for field installation on each refrigerant
circuit. Field refrigerant piping can be connected to the condensing unit.
All expansion valves, liquid line solenoid valves, refrigerant and refrigerant piping are sup-
plied and installed by others.

tions sizes per unit model number.

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. Consider-
ations should be give to:
1. Suctionlinepressuredropduetorefrigerantow.
2. Suction 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.
Table 4 - REFRIGERANT LINE CONNECTIONS on page 17 provides the pressure
drops for given pipe sizes for both liquid and suction lines. The pressure drops given are
per 100 equivalent ft. (30.5 m) of refrigerant piping. These friction losses do not include
any allowances for strainer, filter drier, solenoid valve, isolation valve or fittings.
Nominal pressure drop for solenoids, sight glass, and driers are shown in Table 2 - MIS-
CELLANEOUS LIQUID LINE PRESSURE DROPS on page 16.
Table 3 - REFRIGERATION PIPING CHARGES on page 16 includes approximate
equivalent lengths for copper fittings.
To ensure a solid column of liquid refrigerant to the expansion valve, the total liquid line
pressure drop should never exceed 50 psi (3.4 bar). 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, suction risers should be sized for a mini-
mum of 1000 FPM (5.08 m/s) while the system is operating at minimum capacity to ensure
oil return up the suction riser. Refer to Table 5 under column labeled Nominal Tons (KW)
Unloaded.
Evaporator Below Condensing Unit
On a system where the evaporator is located below the condensing unit, the suction line
must be sized for both pressure drop and oil return. In some cases a double suction riser
must be installed to ensure reliable oil return at reduced loads. Table 3 indicates when a
double suction riser should be used for listed pipe sizes to provide adequate oil return at
reduced loads. The calculated information was based on maintaining a minimum of 1000
fpm (5.08 m/s) refrigerant vapor velocity.
Condenser Below Evaporator
When the condensing unit is located below the evaporator, the liquid line must be de-
signed 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.

QUANTECH
FORM QCC3-EG1 (517)

Selection Data (Cont'd)
OIL TRAPS
All horizontal suction lines should be pitched at least 1/4” per foot (2 cm/m) in the direction
of the refrigerant flow to aid in the return of oil to the compressor. All suction lines with a
vertical rise exceeding 3 feet (.91 meters) should have a “P” trap at the bottom and top
of the riser. Suction lines with a vertical rise exceeding 25 feet (7.6 meters) should be
trapped every 15 feet (4.6 meters).
REFRIGERANT CHARGE
The condensing unit is charged with a dry nitrogen holding charge. The remaining operat-
ing charge for the condensing unit, evaporator coil, and refrigerant piping must be weighed
in after all refrigerant piping is installed, leak checked, and evacuated. Final adjustment of
refrigerant charge should be verified by subcooling values (refer to section on Pre-Startup
for checking subcooling).

(7.2°C).
2. Suction line sizes were calculated based on a nominal maximum pressure drop to 3 PSI/100 ft. (20.7 kPa/30.5 m). When calculating suc-
tionlinepressuredropforaspecicapplication,itshouldbenotedthatsystemcapacitydecreasesassuctionlinepressuredropincreases.
3. Nominal Tons (KW) Unloaded is based on one compressor (per system) operating at design conditions.
4. Based on minimum compressor staging for the given pipe size, a double suction riser should be used to ensure proper oil return to the
compressor on all vertical suction risers. Oil returning up the riser moves up the inner surface of the pipe and depends on the mass velocity
of the refrigerant vapor at the wall surface to move the oil up the vertical rise.
