1InRoom Precision AC Tech Data Manual
Overview
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.
