ROur product groupsAir curtainsIt makes sound economical sense to create an efficientand invisible door that keeps the nice heat inside. If youwant to keep the cold inside you will save even more.Thermozone technology with its precisely adjusted airvelocity gives even protection throughout the opening.Frico air curtains provide the most efficient separationwith the lowest possible energy consumption, regardlessof whether it is the heat or the cold that you want tokeep inside.Radiant heatersFrico radiant heaters imitate the sun, the mostcomfortable and efficient heat source available. Theheat is emitted only when the rays hit a surface andthe room temperature can thus be lowered whilemaintaining experienced (operative) temperature. Thismakes radiant heaters well suited not only for totalheating but also for zone and spot heating, for exampleto avoid cold draughts from windows.Radiant heaters are easy to install and requireminimum maintenance. They heat directly whenswitched on and give no air movement.Fan heatersWe are proud of the worldwide fame Frico fan heatershave gained. They are reliable and are designed for longlife. Our range covers all needs. The investment cost islow compared to other heating systems.A great advantage of fan heaters is the option ofcombining heating and ventilation. Frico fan heaters arecompact, silent and light weight. They are available forelectrical heating as well as for water heating.For more information please visit www.frico.se5

The Frico storyFrico has a long tradition of creating technicallycreative quality products for a comfortable indoorclimate. The product groups that we offer today havebeen introduced along the way.The beginningFriberg & Co was founded in 1932 by civil engineersMr. Eggertz and Mr. Friberg. In 1936 the brand Fricowas registered. Everything was tailor-made according tocustomer demands.The first big order came from the Swedish PublicRailway Authority that needed heaters for their trainwaggons. Many different heating products have passedthe drawing table at Frico since then.Technology and testingQuality has always been a well known characteristic ofFrico products, as well as high technical functionality.Beginning in 1956 research was emphasized and thefinal testing of all products was introduced.The first documented test was the so-called atomictest (the method included measuring of radio activity)to show the strain a car motor is exposed to when notpreheated before starting. Frico’s bestseller at this timewas the motor heater and the test showed that startinga cold motor at -25 °C caused the same wear as driving800 km and a cold start at 0 °C had the same effect asdriving 80 km.5 August 1932Friberg & Co is founded1935First Fricocatalogue1938The ribbed piperadiator1956Technology andtesting1960Frico goesabroad1934The first big order1955Frico fanheaters"Atomic test"6

Widening the scopeFrom 1960 and onwards Frico began widening the scopegeografically, first to the Nordic countries, then Europeand some 25 years later Frico was present worldwide.The introduction of Frico products in warm climatesalso meant a demand for air curtains without heat andthese were introduced in the 1980s. Today they arein common use worldwide for example in cold storageopenings.Quality and sustainable designFrico’s oldest product still offered in the range is theribbed pipe radiator that was introduced in the late1930s. This product has even found a new market inmodern houses and is popular among architects. Ouraim is for all our products to become classics.

Research and developmentWe have one of Europe’s most modern air and soundlaboratories. Research and measurements are doneregularly to develop new products but also to enhanceand improve existing products. Measurements are doneaccording to AMCA and ISO standards.At our test facilities we do measurements on thefollowing aspects:• Airflow• Sound• Winding temperature• Air velocity• Heating capacityThe black cornerThe temperature on the air curtain and surrounding surfaces ismeasured.Airflow measurementThe air curtain blows into the zero pressure chamber. At theopposite end of the rig is a suction fan which readjusts thepressure to zero. The pressure difference (at zero pressure) ismeasured using nozzles. The nozzles are designed accordingto AMCA standard. The airflow is derived from the pressuredifference. AMCA standard defines the airflow that equalseach pressure difference.Acoustic room• Background sound 9 dB(A)• Resting on 76 springs that eliminate vibrations from theproduction• No parallel surfaces• Reverberation time 6 secondsAir curtainPressure measurementNozzleExhaust fanZero pressureAirflow measurement according to AMCA 210-85 standard8

Research and developmentRegular tests and measurements are made todevelop new, but also to improve our existing,products. With radiant heaters it is primarily thetemperature and heating capacity that we areinterested in.Black cornerIn the black corner both external and internaltemperatures are measured in and on the radiantheater as well as on walls and ceilings. Black surfaceshave a very high capacity to absorb heat radiationand therefore give the least advantageous conditionsfor our products.The radiant heater is mounted according to theminimum distances to ceiling, walls and floor givenin the manual. The temperatures are then registeredin a data logger using the thermo-elements placedon the black corner and apparatus surfaces. Thetemperature inside the apparatus is measuredand checked to ensure that the heater meets therequirements regarding safety standards.Black cornerIR cameraThe external temperature can also be measuredusing an IR camera or heat camera as it is alsoknown. It allows contact free measurement becauseno thermo-elements are necessary. The result isan illustration of entire surfaces that gives a goodpicture of the temperature distribution in the heater.Air and sound testsOur test facility for air and sound is among themost modern in Europe. Measurements of air flow,sound and winding temperatures are carried outprimarily on our air curtains and fan heaters. Themeasurements are carried out according to theAMCA and ISO standards.Temperature in the IRC radiant heater taken with an IR camera.The acoustic room has no parallel surfaces and rests on 76 springsthat eliminate vibration from the production. The background noiseis 9 dB(A).With the IR camera, the temperature differential between theelement and sleeve in Comfortinfra CIR is clear.10

RAir curtainsSpecial features of Frico air curtainsThermozone® technologyThirtyfive years of air curtain development in thedemanding Scandinavian climate has given us a uniqueplatform to create air curtains with optimal doorprotection.Thanks to Thermozone technology, performancecan be precisely adjusted to obtain an air curtain withefficient separation that is also comfortable to passthrough.Thermozone air curtains are optimized in:• Airflow geometry• Performance• Sound levelRead more about Thermozone technology in theTechnical handbook.DesignFrico cooperates with leading architects and productdesigners to create today’s aesthetic products. Forvisible mounting there are models that harmonize withexclusive shop interiors as well as industrial buildings.For invisible mounting, the unit is built in with only theoutlet visible.Air curtains for every applicationFrico offers a wide range of options for everyapplication, whether you want your air curtain withoutheat or with electrical or water heating. Our rangeincludes air curtains for all openings from servicehatches to air hangars.Depending on the structure and space around theopening, you may want an air curtain for horizontal orvertical use. Frico offers units that blow from above,below or from the side.Opening without air curtainOpening protected by ThermozoneThe pictures show the effect of a Thermozone placedbetween a cold and a warm zone in a laboratory(blue=2 ºC, red=20 ºC). The laminar airflow is createdby a well adjusted combination of airflow volume andair speed.The testing was carried out by Malmö University,Sweden.Read more about the test in the Technical handbook.10

How to choose the right air curtainUsing Thermozone technology we design units thatare optimized in airflow geometry, performance andsound. This gives you the best possible prerequisites,but that is not enough. To maximise the energyefficiency of the air curtain, careful planning isneeded in the design and installation stages. Belowis detailed information that you may want to returnto later. On the following pages you will find a quickguide to help you choose the right air curtain foryour opening.Important notes:• The whole width (height) of the opening should becovered• The airflow must be sufficient for the height of theopening. The load in the door in terms of wind andpressure difference also needs to be considered (readmore in the Technical handbook), as well as thefrequency of the traffic through the door.• Balanced ventilation is essential, read more in theTechnical handbook• Air curtains cannot prevent excessive draughts orwind speedsBuilding structureBefore installation, it is important to study the structureand ventilation of the building, taking into considerationdraughts, likely wind loads and artificial pressure.Balanced ventilation is essential.If you have a draught problem, the general rule is tochoose an air curtain with heat. Ambient air curtainswithout heat are recommended for use in cold storageopenings and air conditioned premises in warmclimates.For cold climates, the air curtain with heat may beused with only the fan function during the summer tokeep the air conditioned air inside.InstallationThe air curtain should be directed so that a small part ofthe air stream goes out while the main part comes backinto the room. Then the cold outdoor air follows the aircurtain out again and the warm indoor air is retained inthe building.When installing recessed units it is important to allowsufficient supply airflow and an unobstructed outlet.Maintenance access should also be carefully considered.Control the air curtainOnce the correct air curtain has been selected andinstalled, the final factor to consider is the simplicityand ease of controlling the desired temperatures, speedsand airflow direction. Air curtains are controlled invarious ways depending on environmental and financialfactors. We recommend regulation options on differentlevels for each product, from manual regulation withcontrol box and thermostat to automatic regulationbased on indoor and outdoor temperature and whetherthe door is open or closed. The simple solution maybe chosen for financial reasons and for small openingsthat are frequently opened. The advanced solution isintended for premises where the demands are highersuch as large entrances, shopping malls, frequentlyopened industrial doors etc.Door heaters and air curtainsThere are important differences between door heaters,suitable for small doorways, serving hatches, kiosks, etc.and full performance air curtains, primarily designed toprovide an air barrier from the top to the bottom of thedoor.Door heaters heat incoming air and produce a low airflow with high output. The heater may be less expensivethan an air curtain and provide a similar heat outputfigure, but will only cover part of the opening, allowingcool air to enter and warm air to escape. In contrast,air curtains minimise leakage of heated or conditionedinternal air by means of high airflow at high speeds,creating an “invisible door”. With high output andcomplete cover of the opening, the true air curtain ismore effective, therefore more energy efficient.Depending on the application, door heaters may be asufficient source of heat and comfort, but air curtainsare a preferred option for energy efficiency and fullheight doors.SupportYou are very welcome to contact us or our distributorsfor advice in choosing the right air curtain for yourpremises. Below is a check list. The more informationyou can provide us with, the more accurately we canadvice you.• Type and size of premises• The width and height of the opening• Frequency of traffic through the opening• With electrical heat, water heat (which watertemperature) or without heat• Indoor and outdoor temperature• Exposure to windCorrect air curtainWeak air curtain which cannotcover the door heightExcessively strong aircurtain gives energy loss11

– comfort and serviceTo provide good service a comfortable workingenvironment is necessary. Working behind a servicehatch is often associated with cold draughts andpoor air quality due to exhaust fumes. ThermozoneAD100 provides an excellent remedy for theseproblems.Kiosk and service hatchesFitting an AD100 in the opening facilitates the combinationof a high standard of service and accessibility witha good working environment. Service hatches at petrolstations also increase security at night and are an alternativeto double manning.Service cabinetsAD100 in the service cabinet will prevent the waterin the screen wash bucket from freezing and will keepthe air chamber warm and functioning. Heated servicecabinets are a matter of course today in colder climates.They also add customer value.Supplementary heatingAD100 does not simply prevent cold air and pollutionfrom entering, but can also help to keep the area that itis protecting warm.Small openingsService cabinet, petrol station, Göteborg, SwedenAD10017

It is recessed in ceilingsabove entry doors and other small doors where theheight is no greater than 2,5 metres. A low heightmakes it possible to install AR200 where ceiling spaceis limited. The recessed installation and low sound levelmakes AR200 very discreet.ComfortAR200 creates an air barrier, which prevents colddraughts and ensures comfortable heating inside thedoor. An adjustable air blower grille makes it possibleto direct the air for an optimal air curtain effect. AR200can also contribute to the heating of the room when thedoor is closed.Operation and economyThanks to Thermozone Technology AR200 savesenergy. The air barrier reduces energy losses throughthe door opening and the energy consumption of the aircurtain is also low. With an air curtain as a heat sourceit produces heat in the area where it is most needed,and as a result the rest of the premises can be coveredwith less output. Easy installation and maintenanceminimizes the cost and the risk of errors.DesignAR200 is designed for recessed installation and thevisible bottom plate may be painted to make it blendeven better with the premises.Product specifications• Just one model per length, but convertible betweenseveral outputs and 230V~/400V3N~ making it simpleand flexible to adapt the output to current need.• Optimized airflow with Thermozone Technology.• Low unit height (200 mm).• Bottom plate in white lacquered aluminium.Colour: RAL 9016, NCS 0500.

The only visible part of theunit is the discretely placed air intake and air blowergrilles.ADR creates an air barrier that effectively preventscold draughts and ensures a comfortably warmenvironment. Major savings are made by the eliminationof energy losses through openings. An adjustableair blower grille allows you to control the air flow toachieve an optimal air curtain effect.An ADR is fitted with a heater battery for eitherelectricity or water that compensates for any cold airthat may force its way in through the door despitethe air curtain. The air curtain can also contribute toheating the building when the door is closed.Water or snow inside the entrance is dried upeffectively by the heated air from the air curtain. AnADR can also prevent odours, exhaust gases or insectsfrom passing through the opening.Where the openings are wide, it is possible to mountseveral units side by side and control them using asingle thermostat and control panel. The differentproduct lengths make it possible to cover openings ofdifferent widths.• Mounting in false ceilings means that only the intakeand air blower grilles are visible.• Corrosion proof housing made of hot zinc-plated andpowder coated steel panels. Colour: RAL 9016.• Simple suspension using fixed nuts on the top formounting with threaded rod.• The design of the intake air grilles makes separatedust filters superfluous.• The air intake and air blower grilles in telescopicdesign are easily adjusted to suit the false ceiling.• An adjustable air blower grille allows you to direct theairflow for an optimal air curtain effect.Air velocity profileFor other recessed versions, please see www.frico.se78Design and specifications are subject to change without notice.

AC Corinte is mountedstanding next to or hanging above the door opening.Mounted with one unit on either side of the opening,thus creating a classic symmetry, the curtain effect andcomfort is optimized. AC Corinte is available in fivedifferent lenghts covering most needs.ComfortAC Corinte creates an air barrier, which prevents colddraughts and ensures comfortable heating inside thedoor. An adjustable exhaust grille makes it possibleto direct the air for an optimal air curtain effect. ACCorinte can also contribute to the heating of the roomwhen the door is closed.Operation and economyAC Corinte saves energy. The air barrier reducesenergy losses through the door opening and the energyconsumption of the air curtain is also low. With an aircurtain as a heat source it produces heat in the areawhere it is most needed, and as a result the rest of thepremises can be covered with less output.Product facts• An adjustable exhaust grille makes it possible todirect the air for an optimal air curtain effect.• AC Corinte is available for horizontal or verticalmounting.• When mounted vertically, the electrical and/or waterconnections can be made from above or from below.When mounted horizontally from right or left.• Produced in brushed stainless steel as standard, butalso available in polished or mirror-polished stainlesssteel.Air velocity profileDesignAC Corinte is a slim, stylish air curtain in brushedstainless steel.

They can also be mountedin false ceilings, see Fig. 2. Among the hot waterheated models, WAC301/401 and WAC302/402 aremounted in horizontal postion above the opening. Forminimum mounting distance to doorway, see Fig. 1for the electrically heated models. The units must notbe mounted directly above an electrical socket. Formaximum performance the units should cover thewhole width of the opening and be fitted as close to theopening as possible. Several units can be mounted nextto each other to form a continuous air curtain.Mounting below ceiling-mounted sliding doorsWhen mounting above openings with ceiling-mountedsliding doors, a square-shaped air curtain unit cannotbe positioned close enough to the opening because ofthe opening radius of the sliding door. The adaptionset AXT401/402 is dome-shaped and may therefore bepositioned up against the door with the outgoing airstream very close to the opening.Mounting beside the openingWhen space above the doorway is limited, modelsWAC301V/401V and WAC302V/402V can be mountedvertically, thus creating a side blowing air stream.Mounting plates AVMP300 are mounted between unitsand between the lowest unit and the floor. For minimummounting distance to doorway, see Fig. 1 for theelectrically heated models. For maximum performancethe units should cover the whole height of the openingand be fitted as close to the opening as possible.

RAmbient, no heatLengths: 1 and 1,5 metresThermozone ® AC 500Air curtains for doorways between 3 and 6 metresAC500 air curtains are intented for permanentinstallation above doorways with heights of between3 and 6 metres. By separating zones of differenttemperature with a jet of air, the AC500 effectivelyprevents leakage of heated or refrigerated air. In thisway, the energy loss is significantly reduced and acomfortable indoor climate can be maintained. Whenused in freezers and cold storage areas, it reduceshumidity and ice build up.The air curtain also helps to improve the workingenvironment by preventing the intrusion of insects, dustand exhaust fumes.Because the air intake is high where the air is warmer,the temperature difference between ceiling and flooris equalized. The AC500 is built with axial fans thatcombine high pressure with high flow. High velocity airexhausts through a honeycomb grid resulting in a welldefined and layered air stream. There are two ways todirect the air stream for maximum performance: eitherby tilting the whole unit or by adjustment of the airdirectors.For wide doorways, several units can be mountednext to each other.

Inlet hoodUpper silencerFan unitsLower silencerAmbient, no heatThermozone ® AC 600Air curtains that blow from below for large doorwaysAC600 creates a very effective air curtain when air athigh speed is pressed out through a narrow slot in thefloor inside the door opening. The air curtain is directedupward which gives the best possible protection againstcolder and heavier air streaming into the room. TheAC600 unit consists of a pillar with an inlet hood,silencers and fans. It is placed inside and next to thedoor opening. The floor duct has its slot at floor level.The width of the slot and the blow angle are determinedwhen projections are made.The fan unit is made up of one or several fansaccording to the necessary pressure and airflow. Windbreakthrough and draughts in the room are preventedby dimensioning the air curtain’s ray with a sufficientlygreat impulse ( = mass flow x speed).The AC600 provides nearly100 % protection from colddraughts along the floor. Tocompensate for the inwarddirectedpressure force, the aircurtain slot is directed at anoutward angle of about 15°.Design and specifications are subject to change without notice.

Cold storageADA CoolAD300 AADA Cool206

– economy and safetyUsing Thermozone air curtains without heat tomaintain the cold temperature in cold storage isa sensible choice. The test carried out by ManuelCarvalho SA in Portugal illustrates the advantages.Energy losses are lowered, delicate products arebetter protected and accessibility for people andtrucks is improved. An air curtain is also a sensiblechoice from a safety perspective since visibility isimproved and ice build-up on the floor prevented.Manuel Carvalho SA, Portugal replaced plastic stripswith Frico air curtain ADA Cool. They measured thetemperature rise during a 24 hour period, 4 daysbefore the installation of ADA Cool and 4 days after.The graphs below are based on these figures.ADA Cool proved to be much more efficient inkeeping the cold air inside the cold storage.Manuel Carvalho SA found further advantages comparedwith plastic strips. The risk of accidents is reducedwhen build-up of ice on the floor is preventedand visibility through the door is improved.Frico offers several units without heat which are wellsuited for cold storage openings of different sizes.

Controls and accessoriesControls and accessoriesThe control system is the brain of a heatingsystem and decisive for comfort level and energyconsumption. In the product section earlier in thecatalogue we suggest control kits on differentlevels. In this chapter all regulators and accessoriesare presented, thus allowing you to find a tailoredsolution.You are always very welcome to contact us formore information, special solutionsor other questions.The small air curtains have a built in control andcontrol system. For the AD200 range and larger aremote control system is available as an accessory.Heat and airflow should always be controlled. Thereare a variety of control systems from which to choosedepending on requirements and usage.Fan speed controlFor best results the unit should be fan speed regulated.Generally it is sufficient to use a simple 2 or 3 stepcontrol, depending on the size and function of the unit.Variable fan speed controls are also an option. Via timeswitch and/or door contact the unit may be started/stopped or changed between high/low speed.An advanced solution (ADEA) is also available, wherefan speed and temperature are regulated automaticallywith respect to outdoor temperature, room temperatureand whether the door is open or closed.Heat output controlFor electrical heating it is sufficient to use a precise on/off control through a thermostat (variable control isnot necessary to obtain desired air curtain effect). A2-step thermostat improves the precision and makes itpossible to increase or decrease the effect depending onthe heat demand. The electrical heat output can also becontrolled with a control box. For water heating a singlestepthermostat is used.Thermostats can be divided into two types:• Mechanical thermostats, with for example capillarytubes as sensors• Electronic thermostats, with resistance sensorsBoth types of thermostat control the output (on/offcycling) around the desired temperature. It is howeverpossible that temperature fluctuations around the setvalue can be wide (~ ± 1 °C).By using electronic thermostats, the control precisioncan be adjusted to achieve a lower differentiation. Seethe temp. curve for on/off control below.The choice of thermostat depends on the surroundingenvironment. Electronic thermostats are suitable forexample in shop environments where design is usuallymore important and protection class less important.In industrial environments on the other hand, wheredesign is usually less important and protection classmore important, capillary tube thermostats are asuitable choice.Set valueTemperature curve on/off regulation212

It is used to turn the water flowoff and on. The water flow can be fine-tuned manuallywith the adjustment valve and can also be completelyturned off. The water flow may be read off the valve.The kv value for JVF20 is 3,5 and for JVF25 it is 5,5.If the 3-way valve (TRV20/25) is closed, the flowthrough the by-pass valve is low to ensure presence ofwarm water in the heating coil. This leads to instantheat supply when needed and some degree of frostprotection. The actuator (SD20) works on/off.The valve set is available with two different valvedimensions: VR 20 - DN20 (3/4”) and VR 25 - DN25(1”). The by-pass valve dimension is DN10 (3/8”).

– energy saving and comfortLarge energy losses occur through open hatches, doorsand gates. Heated, cooled or air conditioned air disappearsthrough the door, resulting in high energy costs.When cold air gets in through the opening thisin-turn creates problems. Open and draughty doorswith bad insulation result in draught and cold draught.This is often a big problem in the working environmenteven with smaller openings, such as service hatches inkiosks.An open door or hatch also leads to other problems,such as the ingress of exhaust fumes and insects.In many places the door is opened so often, that considerableenergy losses occur and the working environmentbecomes unpleasant.A simple solution to these problems is to install anair curtain. Expressed in simple terms you could saythat air curtains create a barrier between air of differenttemperatures. An invisible door is created which preventsthe indoor air from leaking out and the outdoorair from getting in. This gives lower energy costs anda substantially improved working environment.Without heat, with electrical heat orwater heatFrico’s air curtain range is calledThermozone. The Thermozone-rangeinclude air curtains for every requirementand opening. They are designedto save energy and increase comfort.223Teknisk handbok

RTechnical handbookThermozone ® TechnologyOptimized air curtainsThirty years of air curtain development in thedemanding Scandinavian climate has given usa unique platform to create air curtains withoptimal door protection. Thanks to the Thermozonetechnology, the performance can be preciselyadjusted to obtain an air curtain with efficientseparation that is also comfortable to pass through.Thermozone air curtains are optimized in:• Airflow geometry• Performance• Sound levelAirflow geometryBased on fifty years’ experience of fan technology wehave developed air curtains with the lowest possiblesound levels and turbulence – without compromisingefficiency. Our highly skilled technicians, considerableexperience, and one of Europe’s most modern air andsound laboratories have all contributed to what weconsider to be the optimal combination of all thecomponents in an air curtain.PerformanceImpulse and air velocity are very important factorswhen talking about air curtain performance. The sameimpulse can be obtained in different ways and a higherimpulse does not necessarily mean that the air curtainis more efficient.There are different theories on this subject but wemaintain that we have found the balance between airvolume and velocity that provides optimal efficiency.Furthermore, high speed causes high sound levels andturbulence and large air volumes require a lot of heat.Sound levelFrico focuses strongly on sound levels and we workconstantly on improvements. The kind of fans we useand the overall optimisation in air flow geometry alsoresult in optimized sound levels. Sound is an importantenvironmental factor, equally as important as good light,fresh air and ergonomics. Awareness of and demandsfor lower sound levels are increasing. At Frico we takeresponsibility for this and limit the effects our productshave on overall sound levels. Read more about sound onpage 244.On the following pages you can read more about teststhat illustrate Thermozone technology.240

Technical handbookThe invisible doorThe simulated environment was a cold storage area in afood store where dairy products are held. The area hada direct connection with normal room temperature. Bycarrying out a set of tests at different conditions and bymeasuring the temperature at different points in the airstream, the following charts were generated, showinghow the airflow can effect the temperature in thedifferent areas around the opening.The dark red colour shows room temperature and thedarkest blue colour the lowest cold-storage temperature.The value on the x-axis indicates the distance incentimetres from the unit, the value on the y-axisindicates the distance in centimetres from the floor.To the right of each diagram is a key to the colours/temperature relationship.Opening without air curtainIn an opening without protection you can see how thecold air escapes through the opening, resulting in asignificant amount of warm air ingress.Opening with an air curtain set at the wrong angleIf the angle is too small, warm air will blow in tothe cold storage and result in increased internaltemperature and subsequent energy loss.Opening with an air curtain, velocity too highThe airflow is an important factor in achieving a goodresult with an air curtain. Excessive velocity will resultin energy loss and an increase in the cold storagetemperature.Opening with a correctly adjusted air curtainWith the air curtain correctly set-up a sharp separationis made between the temperature zones.The test was carried out using Thermozone ADA Cool,model ADAC120, by Malmö Technical University,Sweden.241

Technical handbookPerformanceSeparating climate zones where only thetemperature differs is relatively easy. Handlingan opening that is exposed in terms of wind andpressure differences i.e. unbalanced ventilation (readmore on pages 190-191) is more difficult. Our aimis to counteract these problems by achieving theoptimal balance between air volume and air velocity.Not only does this balance make the air curtain moreefficient, but it also provides other advantages suchas a comfortable indoor climate with less noise andturbulence. Energy costs are reduced at the sametime.There are different theories on this subject, butsupported by our tests, we maintain that we have foundthe balance that provides optimal efficiency combinedwith low energy consumption. High velocities requirea lot of energy to build up the necessary pressure.Large air volumes also require a lot of energy.Impulse and air velocity are important factors whentalking about air curtain performance. The impulse isthe mass flow (air volume x density) multiplied by thevelocity and it can be created in different ways. A unitwith high air velocity and a small airflow can have thesame impulse as a unit with low air velocity and a largeairflow.If airflow and air velocity are optimized the air curtaincan perform better than units with higher impulseor higher air velocity. The air velocity profiles shownin the catalogue are based on measurements donein a laboratory environment with a hot-wire probeinstrument, using recognised test methods, the figuresrepresent peak levels.Performance testFrico has developed a method for testing theperformance of air curtains. The test described belowwas carried out as a full scale test. The idea is tocompare the air volume that passes through a door withand without an air curtain. The testing facility usedis described in Fig. 1. The two rooms correspond tooutdoor and indoor environments. There are two ductsequipped with airflow measuring devices between thetwo rooms. An axial fan is mounted in the end of eachduct. The air curtain is installed above the opening.OutdoorsAIRCURTAINIndoorsP [Pa]Q [m³/h]Fig. 1 Testing facility242

Technical handbookWhen the fans are running airflow is created fromthe indoor to the outdoor environment and the exactsame air volume passes through the ducts as throughthe opening. This creates a pressure difference ((DP)between the two rooms. The fans start at a lowspeed which is gradually increased. In the meantimeinformation on airflow and pressure differences is storedin a computer. A curve is created from the data and thisis shown in Fig. 2 below. The opening is measured withand without an air curtain. The result is two curves onwhich the airflow at a certain pressure difference canbe compared.Example: At 3 Pa the airflow through the openingwithout an air curtain is 4 m 3 /s and 1,6 m 3 /s with anair curtain. The difference in airflow shows theefficiency of the air curtain. In this case there is(4-1,6)/4*100 = 60% less flow with an air curtain thanwithout.This makes it possible to compare the performance ofdifferent products under the same circumstances.Fig. 3 shows the result of tests of units constructedon different principles. Type 1 has high air velocityand small airflow, type 2 has medium air velocity,a large airflow and a Thermozone with optimized airvelocity and airflow. The Thermozone is more efficientthan the type 2 unit even though it has 13% lowerimpulse.P [Pa]Without air curtainWith AC402Fig. 2.

Technical handbookSoundSound is an important environmental factor, equallyimportant as good light, fresh air and ergonomics.What we usually call the sound level of a productis actually the sound pressure level. The soundpressure level includes the distance to the soundsource, the position of the sound source andacoustics of the room. This means that a silentproduct is essential, but the whole environmentneeds to be considered to achieve a comfortablesound level.What is sound?Sound is caused by air pressure fluctuations that evolvewhen a sound source vibrates. The sound waves that areproduced are condensation and dillusion of air particleswithout the air in itself moving. A sound wave can havedifferent velocities in different media. In air the soundhas a velocity of 340 m/s.How is sound measured?Sound level is measured in decibel (dB). The dB is alogarithmic unit used to describe a ratio. If the soundlevel is increased by 10 dB, the result is twice as loud(matematically it is 6 dB, but the way we hear it, it is10 dB).It is also useful to know that two equally strong soundsources give an added sound level of 3 dB. Assumeyou have two entrances with two air curtains in eachentrance, all four units with a sound level of 50 dB. Thetotal sound level will then be 56 dB. The first openingwill have a total sound level of 53 dB plus an extra 3 dBfrom the other opening.Points of reference – dB0 The softest sound a person can hear10 Normal breathing30 Recommended max. level for bedrooms40 Quiet office, library50 Large office60 Normal conversation80 Ringing telephone85 Noisy restaurant110 Shouting in ear120 The threshold of painand the threshold of pain is 120 dB.The sound pressure decreases with the distance fromthe source and is also affected by the acoustics of theroom.Sound powerSound power is the energy per time unit (Watt), whichthe object emits. Sound power is calculated from thesound pressure and also uses a logarithmic scale. Soundpower is not dependent on the sound source nor theacoustics of the room, which therefore simplifies thecomparisons of different objects.FrequencyA sound source’s periodical oscillation is its frequency.Frequency is measured as the number of oscillationsper second, where one oscillation per second is 1 Hertz(Hz).Sound power level and sound pressure levelIf the sound source emits a certain sound power level,the following will affect the sound pressure level:1. Direction factor, QSpecifies how the sound is distributed around thesound source. See figure below.2. Distance from sound sourceThe distance from the sound source in metres.3. The rooms equivalent absorption areaThe ability for a surface to absorb sound can beexpressed as an absorption factor, α, which has a valuebetween 0 and 1. The value 1 corresponding to a fullyabsorbing surface and the value 0 to a fully reflectivesurface. The equivalent absorption area of a room isexpressed in m 2 . This can be calculated by multiplyingthe room’s surface area by the surfaces’ absorptionfactor.With these known factors it is possible to calculate thesound pressure if the sound power level is known.Fundamental conceptsSound pressurePressure develops when pressure waves move, forexample in the air. The sound pressure is measured inPascals (Pa). To clarify sound pressure a logarithmicscale is used which is based on the differences betweenthe actual sound pressure level and the sound pressureat the threshold of hearing. The scale has the unitsdecibels (dB), where the threshold of hearing is 0 dB244The distribution of sound around thesound source.Q = 1Q = 2Q = 4Q = 8Middle of roomOn wall or roofBetween wall and roofIn corner

Technical handbookWhy is there draught from an open door?A door needs to be opened to let people andvehicles pass through. An open door also attractsmore customers. The drawback is cold draughtsand energy losses. The amount of air that leaks outthrough an open door depends on the pressuredifference between the indoor and outdoor air.The airflow through an opening is caused by threefactors:• Pressure difference outdoors/indoors• Temperature difference outdoors/indoors• Wind velocity at the openingSimply put you could say that if the conditions on eachside of the door differ in any way, than there will be adraught through the doors. Air leaks out through anopen door to level out the differences in pressure andtemperature. In a heated room this means that warmair leaks out and is replaced by cold air. Wind blowingtowards the opening also affects the airflow.Airflow due to pressure differencesFor an air curtain to function at optimum efficiencyit is important that the over or under pressure inthe building is not too large. The pressure differencebetween the building and its surroundings can beeliminated with balanced ventilation which counteractsthe airflow resulting from pressure differences betweeninternal and external air.Ventilation systems are generally so called zeropressure systems that are mechanically tuned andbased on conditions at the time of adjustment. Whenconditions change, through variations in temperature,air pressure, wind effect or humidity, the balance ofthe zero pressure system will result in either an over orunder pressure in the building (usually under pressure).An air curtain can withstand 5 Pa pressure differenceas a maximum, depending on the circumstances. Evenlower pressure differences could considerably affect theefficiency of the air curtain.With balanced ventilation, comfort levels are raisedand energy costs reduced. Balanced ventilation canbe obtained with pressure regulation through theventilation system, although the most efficient way is tocontinuously measure the pressure difference betweenthe internal and external air and regulate the ventilationbased on this data. Contact us for more information.The airflow due to pressure difference, Q P, can becalculated thus:Airflow due to temperature differencesWarm internal air is less dense and lighter than cold outdoor air, causing a pressure difference at the opening.The cold outside air streams in at the bottom of theopening and forces out warm air through the upperpart of the doorway. This is referred to as the opening”breathing.”The size of the airflow varies accordingto the differences in temperature between internaland external air. The air exchange is therefore said tobe caused by thermal temperature differences. Usingknown values for the temperatures in the building aswell as outdoors, the density of the air masses can becalculated and thereby also the pressure differences andthe airflow through the opening.The airflow, Q T, can be calculated thus:W1.5 ∆ρQ T= • H • µ 0• g • [2]3ρ mwhere W = Width of the door [m]H = Height of the door [m]µ 0= Flow coefficient (0,1-1,0)g = Gravitation coefficient (9,81 m/s 2 )∆ρ = Density differences between the airmassesρ m= Average density of the air massesAirflow due to thermal pressure differencesQ P= W • H •∆P • 2ρ• 0,8 [1](∆P< 5 Pa)where W = Width of the door [m]H = Height of the door [m]∆P = Pressure differencesρ = Density of the air248

Technical handbookWind stressWhen the wind blows against the doorway, airstreams through the opening. The air stream is evenlydistributed over the entire opening. The size of theairflow is thus proportional to the wind velocity at aright angle to the opening. (After a time, the room willhave such a great overpressure that the airflow will belimited to what leaks out through unsealed areas ofthe building.) A wind velocity of 3 m/s equals a loadpressure of 5 Pa.Airflow due to wind stress, Q V, can be calculated thus:υ 10Q v= W • H • 2 • 0,25 x L [3]where W = Width of the doorH = Height of the doorυ 10= Average yearly velocity at a ht. of10 metres (see climate data)0,25 = Wind direction frequency factorL = Position factor, 1 = normal value,>1 for subjected positionTotal airflowTotal airflow through the opening is the sum of the flowdue to temperature and pressure differences and theflow due to wind stress.Q tot= Q T+ Q V+Q P[4]Important notes• If there is negative pressure in the room theperformance of the air curtains will be substantiallyreduced, the ventilation should therefore be balanced.An air curtain can not block a deficit in the amountof air (under pressure) caused by an unbalancedventilation. Mechanical fans are always more powerfulthan any jet of air.• If an opening is exposed to wind, this affects theefficiency of the air curtain. An air curtain maywithstand a wind velocity of 3 m/s as a maximum,depending on the circumstances. In openings highlyexposed to wind more heat can be added. For newconstructions it is advisable to consider relocating theopening or adding a revolving door or double door,preferrably with the openings not in a straight line.• In most cases the air curtain unit should be placed onthe inside of the opening it is meant to protect. Whenprotecting a cold room however it is positioned on thewarm side.• To obtain optimal air curtain performance the aircurtain should be placed as close to the opening aspossible and cover the whole width of the opening.• The direction and speed of the air stream shouldbe adjusted according to the characteristics of thedoorway. Wind pressure affects the air curtain’sperformance and tends to bend the air streaminwards. The air current should therefore be angledoutwards.Total airflow249
