Introduction

Hybrid Chiller Plant

A chiller plant design that allows the operator to choose between multiple energy sources is referred to as a hybrid design. Hybrid chiller plants are receiving increasing attention as valuable options for facility owners. There are various types of hybrid plant designs. They encompass different combinations of electric chillers and other chiller types, including gas or steam absorption chillers. The advantages of having a choice of energy sources will become even more viable as we move further into the new millennium.

Today we hear about utility deregulation. For the first time, building owners can negotiate power supply and natural gas contracts with their traditional supplier, as well as with new suppliers in the market. The fuel-switching flexibility of the hybrid plant puts the owner in a much stronger negotiating position. Similarly, many electric utilities offer attractive off-peak or dual fuel electric rates for applications which are not operating during peak electric system demand, most commonly in the summer months. This represents an opportunity for building owners who can switch to a gas or steam system.

Trane Horizon® Absorption Series

Trane has led in absorption chiller design and manufacturing for four consecutive decades. In fact, Trane is the only North American chiller manufacturer to commercialize double-effect absorption, over 25 years ago. With over 10,000 absorption chillers manufactured and shipped, Trane serves the commercial, industrial and process worldwide markets. Microelectronic controls, adaptive frequency drives and smart purge systems have modernized the technology, making it more capable, more reliable and, in many applications, more economical.

Trane Horizon® Absorption Series, Single-Stage Hot Water- or Steam-Fired Absorption Water Chillers, 500-1350 Tons

Technology You Can Trust

In the early 1990’s, with the assistance of the Gas Research Institute, Trane began developing an innovative series of absorption chillers. In 1995, Horizon chillers began shipping from the Trane manufacturing facility in La Crosse, Wisconsin. The Horizon chiller is so advanced, it redefined industry standards for absorption system integrity. Horizon chiller performance, efficiency and reliability far exceed that of past and present absorption chillers.

Dynamic By Design

Because uninterrupted chiller service is critical to your operation, Horizon chillers are designed to make chilled water reliably, even in the harshest industrial application. Water-tower systems and load requirements can challenge the long-term operation of many standardgrade chillers. The industrial-grade construction of the Horizon chiller accounts for varying load and watertemperature changes, as well as dirty tower water. They are built with corrosive-resistant alloy metals, and precision welded in an ISO 9001 qualitycertified facility. Only extended-life pumps, valves and water boxes are manufactured into their design. For further dynamics, Horizon UCP2 adaptive microprocessor controls react precisely to system diversification. Quality construction, long-life components and adaptive controls are what make the Horizon dynamic by design.

Operates With Energy-Saving, Low-Pressure Steam or Hot Water

The Horizon family includes a singlestage, hot water- or steam-fired chiller line. Able to produce chilled water in the range of 40 to 60°F [4.4 to 15.6°C], these machines use 12 psig [0.83 bar] lowgrade steam or 270°F [132°C] hot water.

Benefits

Making chilled water from these comparatively low-temperature inputs is particularly important for energy conserving applications, such as wasteheat recovery, co-generation equipment and solar-energy-powered cooling.

General

Using refrigerant water helps eliminate refrigerant management or availability concerns. Additionally, absorption technology reduces the use of electric energy.

Features and

Sophisticated Reliability

Horizon controls meet specifications for stand alone or hybrid chiller control. UCP2 adaptive controls are critical to reliable operation. Trane controls are compatible with Integrated Comfort Systems (ICS), and are easily integrated into the Tracer plant system controllers with a single twisted-pair communications cable.

Ideal for Process and Commercial Applications

With Horizon chillers, the application possibilities for the absorption machine are expanded. Capabilities such as lower tower flow, variable evaporator flow, lower chilled-water temperatures and advanced control capabilities make the single-stage Horizon absorption chiller ideal for both process and comfort applications.

When Long-lived Reliability Is Important

Trane has been a long-time proponent of the use of high-quality materials in absorption chiller designs. The lithium bromide temperatures and water refrigerant, typical of all absorbers, can more quickly corrode lower-grade metals in the presence of air. Trane recommends and uses industrial-grade materials to provide long-lived, reliable cooling.

Horizon Single-Stage Absorption Refrigeration Cycle

Refrigeration Cycle

This is an example of typical machine operation at a standard rating point condition (i.e., 85°F [29.4°C] tower, 44°F [6.7°C] leaving chilled water) at full load. Dilute solution has a relatively high refrigerant content and low lithium bromide content. An intermediate solution is a mixture of dilute and concentrated solutions. A concentrated solution is one with a relatively low refrigerant content and high lithium bromide content.

Generator (1)

Dilute solution is pumped into the generator, where it is boiled by the steam or hot water in the tube bundle, creating refrigerant vapor. The refrigerant vapor flows to the condenser (2). The now-concentrated solution flows by gravity, through the solution heat exchanger to the absorber spray system, where it is mixed with dilute solution from the absorber and sprayed on the absorber tube bundle.

Condenser (2)

Refrigerant vapor, produced by the generator, enters the condenser and changes to a liquid through condensation. The heat of condensation is rejected to the cooling water inside the tube bundle.

Evaporator (3)

The liquid refrigerant leaves the condenser through a J tube, where the pressure/temperature is reduced through expansion for delivery to the evaporator at 41°F [5°C]. System water runs through the tube bundle where its heat is transferred to the refrigerant, causing the refrigerant to vaporize/boil. The refrigerant vapor flows to the slightly lower pressure in the absorber.

Absorber (4)

Refrigerant vapor is absorbed by the lithium bromide solution. The now-dilute solution is pumped through the solution heat exchanger and on to the generator. The heat of vapor absorption is rejected via the cooling water inside the tube bundle.

Benefits

(1) Solution 215°F [102°C], Vapor 207°F [97°C]

(6)

Absorption Process (5)

Solution (concentrated) enters the spray system from the generator and enters the spray system, wetting the tubes and providing a liquid surface for the refrigerant vapor (from the evaporator) to absorb into the lithium bromide solution. The solution temperature/ concentration sprayed in the absorber controls the absorber pressure, thereby controlling the evaporator refrigerant temperature.

Cycle

Solution Heat Exchanger (6)

Solution flows through the heat exchanger to be preheated, reducing the heat energy required to induce boiling within the generator, and to decrease the temperature of the solution being returned to the absorber, thus decreasing the load on the cooling tower.

Application

General

The Horizon single-stage steam-fired or hot water absorption chiller is designed to provide 40°F to 60°F [4.4°C to 15.6°C] chilled water, for comfort or process cooling applications, within all three market segments – commercial, industrial and institutional. They are most-often used where an economic analysis of fuel costs versus electrical rates indicates an operating cost advantage.

In many process applications, they can be utilized to convert excess heat energy to provide chilled water for process or comfort applications.

Operating Limits

Trane single-stage absorption chillers operate with nominal 12 psig [0.83 bar] steam or nominal 270°F [132°C] hot water. In all applications, superheat should be limited so steam temperature does not exceed 340°F [171°C].

Waterflows that are within the limits indicated on the appropriate selection table will ensure tube water velocities not exceeding 10 feet per second [3.05 m/sec] in copper tubes and 11 feet per second [3.35 m/sec] in cupronickel tubes. Changes in condenser water temperature should not exceed 1°F per minute in the range from 75°F to 95°F [23.9°C to 35°C].

Sound and Vibration

Absorption units are well-suited for areas where low sound levels are required. The Trane Horizon single-stage steam absorption chiller will operate under normal load conditions at less than 85 dBA sound pressure level. During operation there is no vibration of any components that could be damaging to the chiller or that could transmit objectionable sound or vibration to the building.

Considerations

Chiller Installation

The following should be considered when installing an absorption chiller:

• Rigging and service clearances

• Foundation support

• Chiller isolation for sound/vibration reduction

• Condensate handling

• Steam supply control

• Condenser-water temperature control

• Chilled-water flow control

• Chilled- and condenser-water flow limit

• Generator hot-water application

Cooling-Tower Water Flow

The ARI standard gpm/ton for singlestage absorption chillers is 3.6, however, lower flow through the condenser and absorber section will present an opportunity for a smaller tower, smaller piping, and smaller condenser pump. For more information on lower flows in the cooling tower water circuit, refer to the appropriate Trane engineering bulletin, available from your local Trane representative.

Water Treatment

The use of untreated or improperly treated water may result in scaling, erosion, and corrosion, algae or slime. It is recommended that the services of a qualified water-treatment specialist be used to determine what treatment, if any, is advisable. The Trane Company assumes no responsibility for the results of untreated or improperly treated water.

Combination Systems

Peak energy savings can be achieved when using a combination of electric chillers and absorption chillers for air conditioning loads. The absorption chiller is used to shave seasonal, billable peak-power demands during summer operation, and the electric chiller is run below the allowed demand limit, reducing costly demand charges. Trane offers both electric chillers and absorption chillers with the unit control panel (UCP2) as standard. Although the

General

chillers have different features and modes of operation, the chiller control panel looks and acts the same when used with any chiller model. Each control panel is programmed to monitor the particular chiller for which it was designed, however, maintenance and service personnel only need to become familiar with one control panel. Combined with a Trane Tracer chiller plant has almost unlimited operational flexibility, and all equipment is supplied from a single source.

Multiple Machine Installations

The Trane absorption machine can be applied to series or parallel chilled-water flow, depending upon the design requirement. The arrangement that is best for an individual system should be based on an analysis of system water and temperature rise requirements, system and machine pressure-drop characteristics, and installation cost.

Parallel flow allows minimum chilledwater pressure drop through the machines. However, with one machine “off,” it is not usually possible to maintain the design chilled-water temperature unless one machine is isolated with shut off valves and the chilled-water flow decreased.

Series flow permits design chilled-water temperature at light loads with one machine “off.” However, at all operating conditions, the chilled-water pressure drop through the machine is high.

Accurate chilled-water temperatures can be maintained on individual machines between 100 percent and 10 percent of nominal chiller load, which allows for a wide range of control options. Each chiller has a stand-alone control system to manage the desired water temperature, and also the ability to receive remote commands to support various system demands from a control center. This versatility of control makes the management of more than one machine relatively easy.

system, a

ABS-PRC001-EN8

Selection Procedure

Absorption refrigeration machines are usually selected to provide the required refrigeration capacity with the smallest practical machine of sufficient size. Machine size is based on chilled-water flow rates and temperatures specified for the air side of the system.

Total air-conditioning system first cost can be minimized by a careful analysis of system operating parameters. The effect of flow rates and temperatures, on both the building air side and the refrigeration machine selections, should be investigated to determine which system represents the best investment for the owner.

The information on the following pages provides performance data, at ARI standard conditions, for capacity in tons, efficiency, flow rates and water pressure drops. All capacities are in accordance with the expected ARI 560 Standard revision, and are based on fouling factors of .0001 for the evaporator waterside tubing and .00025 for the absorber and condenser tubing.

Standard Fouling

Unit performance at non-standard fouling factors may vary from standard performance. Fouling factors estimate the heat transfer penalty that coincides with the effect of typical fouling in evaporator and absorber/condenser (cooling) water circuits. All selections should use the standard fouling factor to more accurately estimate the chiller performance in an equipment room and to comply with ARI 560.

SI Units – m2-K/kW

0.018 0.044

Additional Fouling

Any selection that uses a fouling factor greater than 0.0001 for the evaporator tubes, and 0.00025 for the condenser/ absorber tubes, is a more conservative estimate that should only be used if there is an abnormal amount of fouling contaminants in the water systems. The ARI 560 Standard defines “additional fouling” as “Conditions such as water hardness, organic material, suspended solids and/or water velocity may necessitate the use of a greater field fouling allowance than that provided in the Standard Rating of equipment.” The Trane single-stage Horizon Selection program should be used to determine the effect of nonstandard fouling factors. The following guidelines can be used for estimation prior to the selection:

Part Load Performance

The Horizon

single-stage absorption chiller exhibits excellent part-load performance characteristics. Air conditioning system loads are usually significantly less than full-load design conditions. Therefore, the absorption chiller operates at full load a small percentage of the time. Part-load absorption chiller operation is normally associated with reduced tower-water temperatures. At part-load operation, the heat rejected to the cooling tower is less than at full-load operation. Also, partload operation is typically associated with reduced outside wet-bulb temperatures, resulting in improved cooling tower performance. The net result of less heat rejection and lower wet-bulb temperature is cooler tower water entering the chiller and improved unit performance.

Final Selection

A final selection must be done by the local Trane sales engineer using the Trane Horizon

Single-Stage Absorption Selection Program. For applications higher than 1600 feet [500 meters] above sea level, final selection requires review by Absorption Product Marketing. Prior to accessing the computer selection program, the following data inputs should be tabulated:

• Temperature or pressure of the hot

water or steam

• Two of the following three values must

be provided

: – Evaporator Delta-T – Evaporator Flow – Cooling Capacity

• Leaving-Evaporator Water Temperature

• Entering-Absorber Water Temperature

• Cooling Water Flow

• Chilled water and tower water fouling factors

Other options that may also be selected are:

• Type and thickness of tube material

• Type of solution flowing through the evaporator and tower loop

Any limitations or restrictions should

also be given (i.e., pressure drop, gpm etc.).

Absorption chillers can be selected with a wide variety of media other than water (evaporator and absorber/ condenser, or both). For media other than water, contact the local Trane sales office for chiller selections and information.
