This Carrier exclusive provides smart
control and intelligent machine capacity
staging. Unlike many chillers, Carrier
model 30GTN,GTR,GBN,GBR chillers
do not require constant fluid flow. The
ability to operate with variable flow also
allows building owners to realize even
greater overall system energy savings in
the chilled water pumping system of up
to 85%, and not just at the chiller.
Full and part load efficiency
advantage
The 30GTN,GTR,GBN,GBR chillers
with ComfortLink control
outstanding efficiencies (EER [Energy
Efficiency Ratio], COP [coefficient of
performance], and IPLV [integrated part
load value]) in both full (up to 10.0
EER) and part load operation (IPLVs up
to 14.7). Increased part load efficiency is
provided by dual
refrigeration circuits, suction cutoff
unloading, and return fluid temperature
compensation.
The fully integrated ComfortLink
control system maintains
control over the compressors, unloaders,
expansion valves, and condenser fans to
optimize performance as conditions
change. The Carrier exclusive longstroke
electronic expansion valve
operates at reduced
pressures, thereby allowing the control to
operate the fans down to lower outdoor
temperatures. By utilizing valve position
information, the control maintains the
highest possible evaporator pressure and
minimizes the excessive superheat that
conventional thermal expansion valve
(TXV) systems require. Wider operating
ranges equal increased efficiencies and
lower installed costs.

Building design flexibility

Design and consulting engineers will
appreciate the broad selection of sizes
and wide operating range offered by the
30GTN,GTR,GBN,GBR chillers. With
built-in dual chiller control, imaginative
large tonnage systems can be easily
engineered and controlled with smaller,
easier to handle modules. Modular
design allows engineers to consider side
by side, offset, or angled placement to fit
the awkward spaces that the architect

expansion, additional cooling can be
offer
brought on-line and controlled from the
same system.
In some places facility managers
may find that the cash flow provided by
building up large air cooled multi-chiller
plants can easily offset any efficiency
losses when compared to large water
independent
cooled centrifugal type chilled water
plants.

Quality and reliability

To assure
efficient
performance, every chiller is factory run
tested. Individual components are also
tested at many levels to assure that only

life and reliability are also a function of

imbalances are but a few of the
conditions that can hurt the compressor's

Model 30G chillers were one of the first
to offer ground current sensing to
prevent compressor motor burn-out that
would contaminate the system and
potentially threaten the life of future
replacement compressors. The 06E semi-
