The Absorption Chiller.

An Alternative Energy Technology.

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-Drive 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 tot he 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 the electric chillers. What's more, because they fall under the "gas cooling" classification, absorption chillers typically qualify for substantial 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.

Carrier Brings the Benefits of Absorption Cooling Down to Basics.

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.
