Rapidly escalating electrical rates.
Peak demand charges.
Refrigerant restrictions and compliance.
Environmental responsibility.
For those concerned about all of these issues - and
who isn't today - absorption provides a viable alternative to
the traditional electric chiller.
Cost Effective and Environmentally Responsible.
Absorption chillers not only deliver efficient, continuous
cooling with minimal use of electricity, they also use water as
the refrigerant, not the fluorocarbon refrigerants used by mechanical
vapor compression chillers. Yet, they can be used in the same
wide range of settings - hospitals, schools, libraries, retail
facilities, office buildings, industrial processing, and more.
Heat-Driven Cycle.
The basic absorption cycle, while similar to vapor
compression in that both employ an evaporator to vaporize refrigerant
and a condenser to return the refrigerant to its liquid state,
does differ in its method of "compression." Absorption
utilizes a thermal or chemical process which takes
place in the absorber and generator section of the chiller. In
the absorber, a lithium bromide solution absorbs low-pressure
refrigerant water vapor produced in the evaporator. Operation
in a deep vacuum causes the water to evaporate at low temperature,
providing the refrigeration effect necessary to produce chilled
water. The now diluted lithium bromide solution is pumped to the
generator where heat is added to boil off the refrigerant, supplying
vapor to the condenser. Refrigerant liquid returns to the evaporator
while reconcentrated solution returns to the absorber to complete
the cycle. Depending on configuration, reconcentration can occur
in one or more stages.
A Money-Saving Alternative Energy Choice.
Absorption eliminates high electric costs and demand/ratchet
charges because it uses economical natural gas, steam, hot water
or various forms of waste heat as an energy source.
A life-cycle cost analysis, which considers purchase,
installation, maintenance, and operating costs, often shows that
absorption chillers are less expensive to own than electric chillers.
What's more, because they fall under the "gas cooling"
classification, absorption chillers typically qualify for utility
rebates and incentives in many areas of the country - either to
help reduce peak consumption of electric power, or in an effort
to utilize abundant natural gas reserves in summer months.
Quiet, Reliable, and Easy to Maintain.
Relatively few moving parts make absorption chillers
inherently reliable and less subject to mechanical failure than
vapor compression chillers. You'll save time and money on service
and inspection. Low sound and vibration levels allow installation
close to occupied spaces, even on upper floors, without compromising
occupant comfort.
Carrier Sets the Standard Again.
Over half a century ago, Carrier Corporation began
intensive research and development efforts on the absorption-cooling
cycle that led to the first commercially manufactured units for
large tonnage applications. Today, Carrier continues to lead the
way with a variety of absorption chiller products and ongoing
development of existing and new products.
Simple, Reliable Operation.
The 16JB absorption chiller, employing a single generator,
provides one stage of solution reconcentration, making it the
most basic of the cycles available today. The simplicity of the
16JB design, combined with many of its many other quality features,
means inherent high reliability. Few moving parts and simple,
dependable operation reduce downtime, as well as service and maintenance
costs. And because of its quiet operation, it can be installed
in close proximity to occupied areas.
Ideal for Commercial or Industrial Applications.
High reliability and rugged design make the 16JB
an excellent choice for hospitals, libraries, office buildings,
department stores, universities, and industrial processes - for
both new and replacement applications. Available from 100- to
680-tons nominal capacity, operation of the 16JB requires low-pressure
steam or hot water as the heat source, making it ideal for cogeneration
or waste heat applications. Fifteen models ensures a perfect fit.
In the Very Best Tradition.
The simplicity and dependability of the 16JB design
is the result of nearly 50 years of innovative Carrier engineering
and technological leadership. Carrier was the first to manufacture
large single-effect absorbers for the commercial market beginning
in the mid 1940s. In thousands of applications since, the 16JB
has found unparalleled acceptance across the globe.
