RELIABLE AIR-TO-AIR ENERGY RECOVERY Southampton Industrial offers a wide range of air-to-air energy recovery options.Components are proven, cost effective solutions that can be integrated into bothcustom air handlers and dedicated energy recovery systems.

Heat Pipes are one of the most reliable air-to-air energy recovery optionsavailable. The reliability and long life expectancy of this technology can beattributed to the absence of moving parts as well as their rugged constructioncomprised of individually charged and sealed tubes with integral turned fins. Heatpipes are very easy to clean due to the strength and rigidity of the integral finconstruction, and as a result make an excellent heat recovery option for dirty airstream applications. With their compact size and fully customizable dimensions,they can be incorporated into air handling equipment with relative simplicity.

Heat pipe assemblies are constructed with aluminumtubes which commonly have an inside diameter of 1inch (2.5 cm) and a thickness of 0.166 inch (.422 cm).A unique feature of heat pipes is that the fins are anintegral spiral design. This integral fin constructionprovides significant advantages over plate fin orduplex finned designs. The fins are an integral partof the heat pipe wall which provides for addedstructural integrity. The fin material is continuous oneach tube thereby eliminating bond resistance anduneven thermal expansion. This continuous findesign has the added benefit of reducingmaintenance requirements and provides for anextended life span due to the elimination of fin-tubeseparation caused by thermal cycling. The entireassembly is contained in a rugged galvanized steelframe and comes supplied with galvanized steel dustcovers at both ends (304 or 316 stainless steeloptional). The benefits of heat pipe energy recoveryunits are:

1. Independent pipes within the heat pipe assemblyoperate with higher reliability because each pipe isnot dependent on the others for its operation

2. Integral fin construction allows for greater finspacings and easier cleaning without a loss ofefficiency

3. Thermal expansion failures eliminated - each heatpipe is independent within the frame assembly,eliminating bonding problems found in continuousexpanded tube designs. Pipe distortion is alsopractically eliminated

4. Counter flow design results in increased efficiency

5. Flexibility of sizes and effectiveness providessuitability for many different applications

6. Rugged construction reduces maintenancerequirements

7. Bi-directional use in HVAC applications enablesenergy recovery in both winter and summer

8. Silent operation due to no moving parts

9. Passive recovery device requires no powersupply/energy input

10. Anti-corrosion Heresite or Electrofin coatings areavailable for designs requiring protection againstcorrosive air streams

WHAT IS A HEAT PIPE?

HEAT

HOW DOES A HEAT PIPE HEAT RECOVERY UNIT OPERATE?

Heat pipes are self-contained, self-maintainingpassive energy recovery devices. They achieve highcoefficients of thermal transfer through the statechanges of internal vapor and liquid. Heat pipeshave no moving parts, require no external energysource, are reversible and operate completelysilently. They are made of rugged construction andrequire minimal care.

A heat pipe consists of three basic elements: asealed piping arrangement (coil), a capillary wickstructure and a working fluid (refrigerant). Becausethe coil is vacuum sealed, the working fluid is inequilibrium with its own vapor. Heating any part ofthe external surface (using the exhaust air stream)causes the evaporation of the working fluid in thatvicinity (the evaporator region), and the latent heat ofvaporization is absorbed by the vapor formed.

The rapid generation of vapor at any point on thetube wall creates a pressure gradient within the heatpipe which forces the excess vapor to the oppositeside of the pipe, creating a lower pressure andtemperature.

Once on the other side of the heat pipe, the vaporcondenses on the tube wall and the latent heat ofvaporization is generated in the condenser region.This generated heat then transferred to the supplyair stream.

Heat can be removed from the surface at the pointof condensation by conduction, convection orradiation. A continuous process is established by thecapillary pumping forces within the wick structure,which helps return the fluid to the evaporatorsection. The result is a perpetual system ofevaporation and condensation with no moving parts,and requiring no electrical energy input.

Heat pipe heat exchangers are comprised ofindividual tubes, each tested to verify peakperformance. The exchanger provides a simple,efficient and compact method of air-to-air heatrecovery. Heat pipes resemble conventional heatingand cooling coils, however there are importantdifferences:

1. A partition divides the exchanger into twosections, to ensure the separation of the supplyand exhaust air streams.

2. Heat pipes recover heat from the warm exhaustair stream and transfer it to the cold air stream ina counter flow arrangement.

3. All of the tubes in a heat pipe exchanger areconstructed as independent systems.

While heat pipes can recover up to 70% of exhaust airheat under ideal conditions, the average heat recoveryrate is between 50% and 60%. This represents asubstantial saving of heating and cooling costs. Inaddition, heat pipes are fully reversible systemsenabling both summer and winter energy recoverywithout the need for complicated tilt mechanisms orsolenoid valves.

HEAT RECOVERY APPLICATIONS

© SIM 2017

Heat pipes installed in ventilation systems recoverheat from the outgoing exhaust air and transfer it tothe fresh incoming air. This represents a simple, yeteffective way of providing continuous fresh airthroughout the winter and summer months whilerecovering a significant amount of otherwise wastedenergy.

Industrial heat recovery applications

Thanks to their rugged and easy to cleanconstruction, heat pipes are an excellent choice forindustrial applications with dirty or contaminatedexhaust air streams. Available with various options forrows and fins per inch, heat pipes can be designed toachieve a specific effectiveness or pressure drop. Theoptional Heresite or Electrofin coatings also make itan excellent choice for corrosive environments.

Return to process heat recovery

Heat from exhaust air streams can be recovered andreturned as preheated air to a variety of processes(ovens, dryers, etc.).

Process to process heat recovery

Recovered heat from one process can be returned toanother process or heating system. It is sometimespossible to completely heat a second process withthe recovered heat from the first and eliminate theneed for a second heating source.

Dehumidification for air conditioning

The “U-Shaped” dehumidifier heat pipe increases themoisture removal capabilities of an air conditioningsystem and eliminates the need to reheat overcooledair. The “U-Shaped” heat pipe can precool the airclose to its dew point before entering the coolingcoil.

After the cooling coil, the second section of the heatpipe reheats the air up to a comfortable temperature.This process of precooling and reheating air is donewithout the use of energy or pumps. The “U-shaped”heat pipe through dehumidification can effectivelyreduce the tonnage of the overall system resulting inlower operating costs.
