Carrier 19 Series - Manual (Page 2)

The 19 Series: Built to save energy,
save you money and get the job done right
Dr. Willis Carrier invented centrifugal refrigeration in 1922
and today, more than half a century and 25,000 machines
later. Carrier hermetic centrifugal liquid chillers still lead
the way in comfort air conditioning and process cooling.
What’s more, the modern day 19 Series centrifugals are
specifically designed to afford significant dollar savings on
utility bills, in every way possible.
The Carrier 19 Series centrifugal design philosophy has
always been to offer a variable line which meets each unique
specification while at the same time maintaining low first
costs and low operating costs. Incorporated in this
philosophy are such features as the 19 Series inline
impeller design, hermetically sealed compressor-motors,
gear drives and refrigerant options. The success of this
concept can be seen in the 25,000 plus machines which
have been applied to date.
Carrier’s hermetic centrifugals have always used various
refrigerants at different tonnage ranges in order to keep
the heat exchanger size and cost down. Now, over and
above the low first cost concept, Carrier offers refrigerant
options to meet your specific job requirements in the most
efficient way possible.
Tbe full hermetic line consists of four models, each with
a cycle, refrigerant and tonnage range specifically matched
to your application demands. From 100 tons (352 kW) to
2,000 tons (7034 kW), the Carrier hermetic centrifugals are
capable of performance at levels of .85 KW/Ton (3.0 KW/
kW) to .65 KW/Ton (2.3 KW/kW) and lower, depending on
design conditions. With features such as mix-match capa­
bility, high performance heat exchangers, refrigerant
options, multi-pass water boxes as well as tbe 19 Series her­
metic compressor designs, a Carrier centrifugal can be opti­
mized to meet any job requirement. The “Low Energy Con­
sumption Curve” illustrates performance levels possible
within the tonnage capabilities of the 19 Series hermetic line.
You get the most efficient, most reliable, energy-conscious
and completely packaged machine for your particular appli­
cation. The hi-lift capabilities (up to 100 F) make the 19
line ideally suited for brine chilling, ice rink applications
and process cooling. In areas with cooling tower restric­
tions, you can even specify a hi-lift Carrier centrifugal for
use with closed circuit water condensing systems. The
versatile Carrier centrifugals are also designed for low-lift
requirements of today’s energy-conscious market.
Carrier’s computer approach to matching the machine
and capacity to a specific application gives you access to
literally thousands of condenser, compressor, cooler,
refrigerant and pass combinations. Initial costs arc lower
because you select only what you need — a smaller
package. Operating costs are reduced because the mix­
matching of components allows lower energy consumption
selections. In addition, a Carrier Sales Engineer has the
ability to optimize selections, by varying conditions, thru
the use of the Performance Programs. Should your job
requirements demand performance other than what is
shown in this catalog, contact your Carrier Sales Engineer
(refer to page 50 for the office nearest you). Thru com­
puterized selection he will be able to design your “custom
built” hermetic centrifugal.
Not only can Carrier Sales Engineers optimize your
refrigeration requirements but they can optimize your total
system as well. Thru various specialized computer pro­
grams, for example, a Carrier Sales Engineer can vary your
leaving chilled water temperature a degree or increase your
chilled water temperature differential from 10 to 14 F and
show how the total system is affected with respect to
operating costs. In this complex market of low energy con­
sumption as well as low first cost, Carrier can offer you
productive ways to reduce your costs.
