CM Series Precision Air Conditioner Owners Manual
Product Description
DESCRIPTION
Data subject to change without notice.
All sensitive electronic equipment
requires a stable environment for
optimum performance. The
Ecos
aire
®
Precision Environmental
Control system provides the best
possible protection for any
application.
The
Ecos
aire
®
product line is
made up of feature-rich, energy effi-
cient premium products that are
available in sizes and configurations
to suit any application - even corro-
sive industrial process environments.
Ecos
aire
®
contains unique, highly
engineered subsystems that no other
manufacturer duplicates, ensuring
continuous, simultaneous control of
temperature, humidity, air purity and
air flow at each operating site.
Ecos
aire
®
performs with the high-
est energy efficiency through intelli-
gent design: less energy wasted on
undesired latent cooling, on-demand
dehumidification, and the state-of-
the-art Supervis
aire
®
Control
System. These new controls offer
maximum design flexibility, network-
able units, BACNET
TM
, and
MODBUS
TM
compatibility. This
allows remote monitoring and alarm
logging from either a graphics display
panel, personal computer, or via
modem.
The
Ecos
aire
®
product line offers
the maximum in environmental con-
trol performance and the lowest life-
cycle cost of ownership.
Stable environmental conditions
are further ensured by on-demand
dehumidification. Unlike convention-
al computer-grade systems that con-
stantly dehumidify,
Ecos
aire
®
elimi-
nates the costly process of removing
and then replacing moisture.
The Supervis
aire
®
Microprocessor
Controls provide extremely user-
friendly, programmable monitoring
and control for all
Ecos
aire
®
Precision Environmental Control sys-
tems. Individual
Ecos
aire
®
units can
be connected on a built-in local area
network together with a supervisory
panel complete with a backlit graph-
ics display for robust, redundant
environment control. At the same
time, the network can be connected
to a personal computer supervisory
system, or to a BACNET
TM
, or MOD-
BUS
TM
network.
The LCD panel is large and easy
to read (4 x 20 characters) and the
simple layout provides an easy-to-
use interface for the operator.
English language menus (other lan-
guages available) and built-in diag-
nostics walk the user step-by-step
through the monitoring and control of
the system.
A powerful 16-bit microprocessor
ensures high program-execution
speed and efficient real-time man-
agement of even the fastest tran-
sients.
The computer-site conditions and
utilities will determine the type of
environmental control units selected.
A cooling-load calculation based on
design criteria should be performed
according to standard air-condition-
ing practice. The calculation should
include the heat gains of: exterior
walls and windows; area exposed to
unconditioned spaces (i.e. partitions,
ceilings, and floors); people; lighting;
and all computer and auxiliary
equipment. With this information
the type, size and number of
Ecos
aire
®
units can be selected to
best match the equipment configura-
tion in the computer room.
Allowances for expansion and redun-
dancy should be considered at this
time.
While many important factors
require evaluation when designing a
computer room, the most important
are security, expandability, location
within the building, proximity of relat-
ed data processing operations and
proximity to outdoor air-conditioning
components. Computer rooms are
best located in a central part of a
building so as not to be affected by
outside temperature and humidity.
When a room must be designed with
an outside wall, the wall should be
insulated and windows should be
kept to a minimum. Thermopane
windows should be used to prevent
condensation. Equipment access
through doors, elevators, etc., as well
as elevator capacity, must be
carefully considered.
