Overview
C
General
The InRoom product family is an
assemble to order (ATO) line of
perimeter air conditioning
systems that provide precision
cooling for data centers and
server rooms.
Precision environmental close
control requirements now reach
far beyond the confines of the
traditional data center or
computer room to encompass a
larger suite of applications,
referred to as technology rooms.
Critical environment applications
include:
• Computer rooms
• Telecommunication facilities
• Clean rooms
• Power equipment
• Medical equipment rooms
• Archives
• LAN/WAN environments
A worldwide network of APC
representatives is fully qualified
to provide engineering, sales,
installation and service for our
products.
APC warrants all parts for 1 year.
Models
The InRoom precision air
conditioning unit is available in
five sizes. The system is available
in both chilled water and direct
expansion for a combination of
six heat rejection methods.
Select from ACPDX21-86 and
ACPCW40-150.
Room Air Distribution
The InRoom downflow system
draws warm exhaust air in
through the top of the unit and
cools it. The cool air is distributed
back into the room through a
raised floor plenum. These
systems are ideal for areas with
raised floors greater than 305 mm
(10 in) high. Upflow systems
draw warm exhaust air in through
the front of the unit. The warm
exhaust air is then cooled and
discharged back into the room
through a plenum or ductwork.
Upflow systems are ideal for
areas without a raised floor, but
can also be used in a raised floor
environment.
The InRoom precision air
conditioner delivers high volume
airflow to help eliminate hot spots
in densely populated
environments.

Scalable Solution for Critical Environments
Temperature and Humidity Design Conditions
Maintenance of temperature and
humidity design conditions is
critical to the smooth operation of
a technology room. Based on
ASHRAE TC9.9, the
recommended design conditions
for class one and class two
environments should be 20–25°C
(68–77°F) and 40–55% relative
humidity (R.H.). Precision air
conditioning is designed to
maintain temperature at ±2°F and
humidity at ±3–5% R.H. 24 hours
a day, 365 days a year. Vapor
barriers and sealed rooms are
required to maintain these
tolerances. In contrast, comfort
systems are designed to maintain
±5°F from the temperature
setpoint. There is usually no
dedicated humidity control and
the simple controllers cannot
maintain the setpoint tolerance
required for temperature,
allowing potentially harmful
temperature and humidity swings
to occur. This is not acceptable for
sensitive electronic equipment.
Air Quality
Precision air conditioners provide
a high volume of air flow, around
600 CFM/ton (286 L/m, 150
CFM/kW). This high CFM moves
more air through the space
improving air distribution and
reducing the chance of localized
hot spots. It also allows more air
to move through filters, ensuring
a cleaner environment. This
requires a moderate-to highefficiency filter bank to minimize
airborne particles.
Low Humidity
Low humidity greatly increases
the possibility of static electric
discharges. Static discharges can
corrupt data and damage
hardware.
High Humidity
High humidity can result in tape
surface deterioration, head
crashes, condensation, corrosion,
paper handling problems and gold
and silver migration leading to
component and board failure.
High & Low Temperature
A high or low temperature or
rapid temperature swings can
corrupt data processing and shut
down an entire system.
Temperature variations can alter
the electrical and physical
characteristics of electronic chips
and other board components
causing faulty operation or
failure. These problems may be
transient or may last for days.
Transient problems can be very
difficult to diagnose and repair.
Efficiency and Reliability
The use of energy efficient, direct
drive fans along with fewer
moving internal parts eliminate
most potentials for failure. Scroll
compressor technology provides
unparalleled efficiency and constant, reliable operation with an
ability to withstand liquid
refrigerant ‘slugging’ which is a
major cause of compressor failure. The compressor is also
equipped with an internal high
pressure sensor which opens a
bypass valve in case of high
pressure. This ensures internal
pressure compensation takes
place and damage to the
compressor is avoided.
APC InRoom The Right Solution
The APC InRoom cooling unit
provides the maximum amount of
precision cooling in a compact
footprint with the lowest
operating cost and noise level.
Dedicated Dehumidification Cycle
A dedicated dehumidification
cycle allows the system to
increase latent capacity without
boosting compressor capacity,
and also lowers the requirement
for reheat. To achieve
dehumidification, the electronic
expansion valve is first partially
closed. The reduction of the
refrigerant mass flow makes the
evaporation temperature drop,
which lets the surface temperature
in a part of the evaporator fall
below the dew point of the air,
causing dehumidification. For
increased dehumidification, the
fan speed is reduced. With a
constant cooling capacity, the
temperature of the air which
flows through the heat exchanger
coil passes below the dew point.
The moisture contained in the air
condenses on the heat exchanger,
gathers in the condensate pan, and
is carried away by the drain. To
achieve humidification for the
DX units with cabinet size 1 and
all CW units, the fan speed is
reduced. For the DX units with
cabinet size 2–5, approximately
one third of the evaporator is
isolated from the refrigerant flow
by a solenoid valve to achieve
dehumidification by lowering the
evaporator temperature below the
dew point.

Standard Features
Insulated Panels
The frame is constructed of 16
gauge steel sheet metal for
maximum strength. All exterior
panels and corner posts on the
frame are powder coated for
durability and an attractive finish.
The side panels are double wall
construction (inner and outer
panels) with insulation between.
The insulation is 12 mm (1/2 in)
thick fiberglass. The walls isolate
the insulation from the air stream
and further reduce sound levels.
Panels are hinged and removable
for easy access. The cabinet is
serviceable from the front of the
unit.
Electronically Commutated (EC) Fans
Each unit is equipped with
electronically commutated (EC)
fan modules. This technology
increases fan efficiency by up to
30% while reducing operating
costs. Each fan module has an
anti-vibration mounting to isolate
it from the unit structure.
Electrical Panel
The electrical panel contains the
contactors, starters, overload
protection devices, and input
power disconnects.
Main Power Disconnect Switch
A main power disconnect switch
disconnects all high voltage
power to the unit if necessary.
The disconnect switch is
accessible without removing the
electric box cover.
Network Management Card
Permits multi-level access to
monitoring, control, and event
notification features over the
building management network.
Refrigeration System and Compressor
The refrigeration system operates
under a master controller for
greater efficiency and accuracy.
Suction and discharge pressures
(DX models) are monitored and
electronically controlled. The
scroll compressors are designed
for year-round operation with a
15-year life expectancy. The
controller microprocessor
provides real-time suction and
discharge pressure readings
reported by transducers installed
on the refrigeration system.
For compressor protection, the
InRoom precision air conditioner
utilizes charge isolation and crank
case heaters during off cycles
(DX only). This eliminates the
threat of liquid refrigerant
migration that could lead to
compressor slugging and
lubrication issues.
Mains Automatic Transfer Switches
Mains automatic transfer switches
allow two power sources to be
connected to the cooling unit. A
secondary power source
(generator or UPS) can be
automatically transferred in the
event of a failure of the main
power source to maintain cooling.
Programmable switches are
voltage adjustable with On and
Off delay which can be adjusted
from 0 to 20 seconds. The Off
delay should be set to 3 seconds.
Contact customer support for
assistance to determine your
requirements.
Duct Flange
A 25 mm (1 in) duct flange is
included for the upflow units to
provide convenient connection to
external ductwork for either
supply or return air as needed.
Evaporative Freeze Protection
Suction pressure is actively
monitored by two individual
sensors and controlled by the
microprocessor controller to
calculate the opening of the
electronic expansion valve,
eliminating the risk of condensate
freeze-up on the evaporator coil.
Redundant Group Control
Allows up to 16 units to
communicate with each other for
redundancy, demand fighting
prevention, and mode assist.
Global sharing of certain settings
requires a twisted pair shielded
wiring interconnection.
30% ASHRAE 52.1 Filters
The filtration of conditioned air is
extremely vital to maintaining the
clean, particle-free environment
required by electrical equipment.
The system uses 30% (100
micron) filters, with full depth
filter pleats. Deeper filters
produce a lower pressure drop,
requiring less energy during
normal operation. Filters are
replaceable through the front of
the upflow unit and through the
top of the downflow unit.
Condenser (Direct Expansion units only)
Standard air cooled condensers
are suitable for cooling up to the
maximum ambient temperature of
either 35°C (95°F) or 46.1°C
(115°F) depending on the
requirement. These condensers
have variable fan speed controls
to allow operation down to
-28.9°C (-20°F).
3InRoom Precision AC Tech Data Manual
Optional Features
Humidifier
The humidifier utilizes a pure
steam generator specifically
designed for precision
environmental close control. The
pure steam eliminates
contaminating mineral deposits,
potentially harmful bacteria,
white dust, and excessive
humidity. The humidifier requires
little scheduled maintenance. The
humidifier is proportionally
controlled to meet the
humidification demands of the
conditioned space. Humidifier
canisters are replaceable.
Electric Reheat
Electric reheat elements are low
watt density, wired for 3-phase
and loaded equally on all three
phases, SCR controlled, and
electrically and thermally
protected by both automatic and
manual reset thermal cut outs.
Reheat coils are stainless steel,
tubular fin construction.
Spot Water Detector
The solid-state spot water
detector is available for both 50
and 60 Hz cooling units. The spot
water detector activates an
audible alarm on the controller
when moisture is detected.
Smoke Detector
The factory-installed smoke
detector is designed to sense
smoke in the return air stream.
Upon detection of smoke, an
audible and visual alarm on the
microprocessor controller will be
activated and the unit will be shut
down immediately.
Hot Gas Bypass Valve
The hot gas bypass valve
(HGBV) adjusts the flow of
compressor discharge gas to the
evaporator coil at low load
conditions to protect the coil from
freezing and the compressor from
excessive cycling. 60 Hz cooling
units use a mechanical HGBV.
50 Hz cooling units use an
electronically controlled HGBV.
On 50 Hz cooling units, the
HGBV option requires the analog
extension board EAIO.
Cable Leak Detector (60 Hz only)
The optional 6 m (20 ft) leak
detection sensing cable (APC part
number ACAC75105) is available
for 60 Hz cooling units only. The
cable leak detector is placed on
the floor or subfloor around all
possible leak sources. If water or
other conductive liquids contact
the cable anywhere along its
length, the master controller
visually and audibly announces
the leak.
Floorstand
The floorstand raises the unit
above the subfloor to match the
height of the raised floor. Heights
are available from 254 mm (10
in) to 610 mm (24 in) in 76.2 mm
(3 in) increments and are
adjustable +/– 38.1 mm (1.5 in).
Adjustment is provided by
threaded pedestals. Vibrationabsorbing pads are included. The
floorstand, pedestal, and pads
ship loose. In areas where
earthquakes are a concern,
seismic floorstands are available
in 305 mm (12 in), 457 mm (18
in), and 610 mm (24 in) heights.
Plenums
Discharge plenums are available
on upflow configurations. This
application is recommended in
rooms where raised floors are not
available for air distribution.
Discharge air should be ducted
down cold aisles.
Base Plenum
Insulated base plenums are
available for downflow cooling
units where raised floors are not
available for air distribution. Four
front-discharge configurations are
available equipped with dampers,
grilles, flexible ductwork or open.
All configurations are 450 mm
(17.7 in) high and sit beneath the
InRoom cooling unit.
Water Regulating Valves
Water and fluid cooled systems
utilize two- or three-way valves to
regulate the amount of water or
glycol supplied to the condenser
in response to refrigerant
discharge pressure. The standard
valve pressure rating is 28 kPa
(400 psi).
Extreme Low Temperature Kit (Direct Expansion units only)
Extreme Low Temperature Kits
for air cooled condensers are
available for operation below
–34.4°C (–30°F). The optional
kit consists of pressure control
valves and receivers for the liquid
return side of the refrigerant
piping.

Condensers
na3012 a
60 Hz
Air cooled condensers are designed to reject heat from refrigerant based cooling equipment and are designed to
be installed outdoors. The condensers are self-contained in a lighweight aluminum cabinet designed for
mounting to a horizontal surface. The cabinet houses condenser coils and fan assemblies. Each condenser coil
is a copper turb, aluminum finned coil.
The capacity of the condenser is based on the rated capacity of the coil. In the case of dual circuit units, the
model number is based on the combined capacity of both coils. The coil is a closed-loop refrigerant condensing
heat exchanger in which refrigerant is continuously circulated by the pressure differential created by a
compressor.
The compressor increases refrigerant pressure to a level sufficiently high for it to be cooled and condensed into
liquid by the effect of ambient air being drawn over the condenser coil. The fans have corrosion resistant,
multi-blade impellers designed for high aerodynamic efficiency which results in lower power consumption,
lower noise levels and longer life. Each fan utilizes a direct driven motor with maintenance free bearings. The
fan motors are internally protected from overload. Fans have finger guard grilles to protect operators from
injury and keep large tools or other objects from falling into the fan.
Electrical controls are in a weather proof enclosure and isolated from the rest of the equipment. The electrical
box has a removable front access panel which is safety interlocked with the service disconnect switch,
preventing the panel from being removed when the switch is in the ON position. The switch must be turned off
to gain access to the electrical components.

Different variations of the InRoom product range are defined by the airflow direction, the number of
refrigerant circuits, and the type of cooling system. There are five cabinet sizes. The front service access for all
cabinet sizes of the InRoom Precision Air Conditioner is 1 m (39 in).
The InRoom Fluid Cooled (Glycol) system with Economizer Coil differs from the other versions by having a
larger cabinet size, not a larger capacity. There are no Fluid Cooled (Glycol ) systems with Economizer Coils in
Cabinet Size 1.

Fluid Cooled (Glycol) System with Economizer
Fluid Cooled (Glycol)
InRoom Fluid Cooled (Glycol) systems are
completely charged and factory tested in a sealed
system for reliability. In mid to low ambient
climates, an economizer coil can be used to
increase efficiency and extend compressor life.
Economizer operation greatly reduces the energy
consumption of the system. Water regulating
valves control head pressure.
• System is used with a fluid cooler.
• Factory-tested as a sealed system.
• Eliminates the need for field refrigerant
piping.
• No requirement for water treatment.
• Economizer option provides high
efficiency.
• Low maintenance.
na2837a
The InRoom Fluid Cooled (Glycol)
System with Economizer is configured
with both the glycol factory sealed system
and an Economizer coil. During cold
ambient conditions, the compressorized
system will shut down and utilize the cold
outdoor air to cool the glycol system,
rerouting it from the heat exchanger to the
Economizer coil for efficient operation.

The InRoom Fluid Cooled (Glycol) System
na2843a
Fluid Cooled (Glycol) System with
Chilled Water Cooling System
na284 4a
Chilled Water Cooling System
with Chilled Water System is a combination of a
factory sealed glycol system and a chilled water
system and contains two separate cooling coils.
The controller microprocessor manages the
systems to allow the glycol system to operate as
standby to the chilled water system or vice
versa, giving the added security of back-up
cooling to the computer room.
Chilled Water
InRoom Chilled Water systems are available in a
packaged fan-coil design. Room air is
recirculated through the cooling coil, which
transfers the heat load directly into the chilled
water ring main. Water flow rate is regulated by
a 2- or 3-way valve controlled by the controller
microprocessor. Cooling towers are used as a
source of heat rejection and can be used to serve
multiple indoor units. Towers utilizing outdoor
air require water treatment.
• The system is used with a cooling tower or
other source of water.
• Factory sealed and tested system.
• The need for field refrigerant piping is
eliminated.

MultiCool - Air Cooled System with
Chilled Water Cooling System
Air cooled systems are not pre-charged from the
factory and require field refrigerant piping. Each
installation requires an engineered piping solution.
APC strongly recommends installation by a highly
qualified refrigeration contractor to avoid improper
elevation and long piping runs. The Air Cooled
system uses refrigerant as the heat transfer medium.
Room air recirculates through the InRoom unit
which houses the evaporator coil, scroll compressor,
and refrigeration system. A remotely mounted aircooled condenser is connected to the unit. The
sealed refrigeration circuit will absorb the room heat
load and reject it to the outside atmosphere.
• System used with a remote air cooled condenser
• Field installed refrigerant piping is required
• Low maintenance
The MultiCool System is a combination
of the Air Cooled System and the
Chilled Water System and contains two
separate cooling coils. The controller
microprocessor manages the MultiCool
System to allow the air cooled by the Air
Cooled system to operate as a standby
system to the Chilled Water (CW)
system or vice versa, giving the added
security of back-up cooling to the
computer room.
