EC-Technology: Keyword Energy EfficiencyGEA Cassette-Geko Fan Coil UnitWhat are EC motors?EC-motors (= electronically commutated motors) are DCmotors, where the rotor is not performed as a coil, like inusual AC motors, but consists of a permanent magnet.Electronic control of the motor enables continuous operation,where the integrated electronics ensures alternatingmagnetic field which adjusts itself to the relevant speed(refer to Fig. 11). As compared to mechanical commutating(brushes), there are no moving regulation componentsthat generate additional losses.In such a way the motor operates at optimal conditions, resultingin maximum torque and minimum losses. The efficiencyrate of the EC motors used by GEA is twice as highas the comparable AC motors. The application of this technologyin GEA fan coil units makes it possible to achievehigh efficiency rates for fan motors - especially in part-loadmode.North poleRegulation RegulationCoilCoilSouth poleSouthNorth poleCurrent flow Current flowFig. 11: Functional description of an EC motor(electronical commutation)This results in the reduction of electrical power consumption of an EC fan by up to 75%.100Comparison AC/EC fan - Single Cassette90Electrical power consumption [W]807060504030-75%47%-46%AC fan CS1AC fan CS2AC fan CS3EC fan-67%2010-74%-72%0200 300 400 500 600 700 800 900Air volume flow [m³/h]Fig. 12: Comparison - electrical power consumption EC/AC fan8 PR-2010-0107-GB • Subject to modifications • Status 06/2011

GEA Cassette-Geko Fan Coil UnitEC-Technology: Keyword Energy EfficiencyFurther aspects: – Continuous operation– Low generation of heat– Established and usual high motor quality– Same design for 50 and 60 HzContinuous GEA MATRIX controlsEC fans featuring continuous operation mode offer a few of benefits:– Room temperature control is performed with a higher accuracy, because occurringtemperature differences can be addressed with the accordingly adjusted fan speed.This effect is assisted by using 3-point regulation valves (hydraulic method).– Variable fan speed control can compensate for fluctuating conditions of heating andcooling medium. Example: season-related different inlet temperature of heat generatoror fluctuating volume flow rates (hydraulics)– With standard AC fans the fan speed, which is optimal for room temperature control,must be adapted to the available fan speed stages which often leads to rapidincrease of motor RPM and thus electrical power consumption.– With continuous speed regulation - "hard" fan speed changes are eliminated, whichprovides additional acoustical comfort.The GEA MATRIX controls uses these features by making the following functionsavailable, the customer can select between automatic and manual operation:Automatic mode:Room temperature control with continuous regulation (1.5-10 V) of a stepless EC fan.The fan continuously operates within the minimum and maximum air volumes.Using the display control panel OP50/51 a speed limitation can be activated (mutefunction) in order to prevent an acoustic overshoot in automatic mode. This upper RPMlimit can be separately set for each control panel.As an additional measure to avoid possible on site acoustical resonance occurrences,up to three speed ranges can be hidden using MATRIX.PC software.Manual mode:OP 50/51 (control panel with display): continuous fan setting using rotary switchbetween minimum and maximum air volume flow rate.OP30/31 and OP44: (speed-stage control panel): 5-speed fan setting with speed1 = minimum air volume flow rate and speed 5 = maximum air volume flow rate.Percentage values (regarding maximum air volume flow rate) for speeds 2-4 arepre-configured by the factory (default values) and can be changed on site by othersusing MATRIX.PC.PR-2010-0107-GB • Subject to modifications • Status 06/2011 9

EC-Technology: Keyword Energy EfficiencyGEA Cassette-Geko Fan Coil UnitEUROVENT Energy LabelWithin the framework of EU regulations (Eco-Design Directive) clear limits will be setin the future with respect to the energy efficiency of available technological standards.EUROVENT, as the European Association of Manufacturers of HVAC equipment,anticipates this development by having published Energy Label for fan coil units toinclude 7 energy efficiency classes (A to G) in January 2011.In this case the energy efficiency is composed of time-weighted relationship betweencooling or heating output and consumed electrical power of the fan.Fan coil units that are equipped with an energy-efficient temperature regulation system(GEA MATRIX) and, depending on situation-related heating or cooling demand, reactwith adjusted fan speed must consider the time share of the corresponding speedstages for the evaluation of energy efficiency. For the description of time-connectedrelationships EUROVENT uses coefficient A (maximum), B (medium) and C (minimumspeed). These indicators vary, depending on heating or cooling operation mode.Fan stage Coefficient Time percentageCooling HeatingHigh (maximum) A 5 % 5 %Medium B 30 % 25 %Low (minimum) C 65 % 70 %The energy efficiency relationship is composed of time-weighted shares and ispresented in the examples using the following formulas:Cooling (FCEER):••••A × QFCEERKHighSpeed+ B×Q KMediumSpeed+ C×Q= -----------------------------------------------------------------------------------------------------------------------------------------------KLowSpeedA×Pe HighSpeed+ B×Pe MediumSpeed+ C×QPe LowSpeedFan Coil Energy Efficiency Ratio - total cooling capacity(= Energy efficiency relationship)Heating (FCCOP):FCCOP=• • •A×Q HHighSpeed+ B×Q HMediumSpeed+ C×Q-----------------------------------------------------------------------------------------------------------------------------------------------HLowSpeedA×Pe HighSpeed+ B × Pe MediumSpeed+ C×Pe LowSpeedFan Coil Coefficient Of Performance(= Performance coefficient of fan coil unit)•with Q K = Total cooling capacity•mit Q H = Heating capacitymit Pe = Electrical power consumption of fanHigher numerical value of these indicators stands for especially outstanding energyefficiency.10 PR-2010-0107-GB • Subject to modifications • Status 06/2011

GEA Cassette-Geko Fan Coil UnitSound pressure level dB(A)The sound pressure specifications in the tableson pages 6-25 and 28 apply to the reverberantsound field of a room with a volume of 100 m 3and a reverberation time of 0.5 s.To determine the anticipated sound pressurelevel at the installation location, refer to theA-rated sound power level in conjunction withthe conversion diagram in Fig. 16.Example:Three Cassette Gekos of type GCS1 are to beinstalled in a conference room with dimensions(20 x 10 x 4m). They are to be operated atstage 2, i.e. the sound power level should be43 dB(A), see p. 28.Determining the sound pressure level1. Based on the room volume (800 m 3 ),absorption surface of approx. 100 m 2 Sabinis estimated in accordance with the diagram inFig. 16 “Homes, offices, hotel rooms,conference rooms”.2. The mean distance to the Cassette Gekos isassumed to be approx. 3m and the directioncoefficient to be “2”, Fig. 15. The intersection ofthe dotted sample lines in the diagram inFig. 12 produces the sound level difference:ΔL~12 dB3. The anticipated A-rated sound pressurelevel L P for a unit is thus:L P = L W – ΔL = 43 dB(A) – 12 dB = 31 dB(A)According to Fig. 14, appr. 4.5 dB.The anticipated sound pressure level in theroom is thus:L Pges . = L P + 4.5 dB = 31 dB(A) + 4.5 dB= 35.5 dB(A)The value which is the minimum requirement,according to Tab. 1, is therefore fulfilled.Table “A-sound pressure level” LP 1) – guidevalues from VDI 2081Tab. 1Room typeA-sound leveldB(A)Mean reverberation time(s)Home * **(Hotel room) at night 35/30 30/25 0,5Living space (daytime) 35 30 0,5AuditoriumsTV studio 30 25 1,5Concert hall 30 25 2,0Opera house 30 25 1,5Theatre 35 30 1,0Cinema 40 30 1,0Lecture theatre 40 35 1,0Reading room 40 35 1,0Seminar room 40 35 1,0School classroom 40 35 1,0OfficesConference room 40 35 1,0Restroom 40 35 0,5Break room 40 35 0,5Small office 40 35 0,5Open-plan office 50 45 0,5Church 35 25 3,0Museum 40 35 1,5Ticket office 45 40 1,5Computer room 55 40 1,5Laboratory 45 40 2,0Restaurant 40 to 55 2) 1,0Kitchen 45 to 60 2) 1,5* = minimum requirements** = increased requirements1) Also see applicable building regulations, DIN standardsand VDI guidelines (e.g. DIN 4109, DIN 1946, VDI 2058);2) Depending on useIncrease in sound level (dB)Increase in sound level dB10987654,54321Fig. 14Direction coefficientsFig. 1512 3 4 5 6 8 10Number of unitsDirection coefficient 2(hemispherical radiation):Unit is mounted freely in the middle of asurfaceDirection coefficient 4(quarter-spherical radiation):Unit borders on two room surfacesDirection coefficient 8(eight-spherical radiation):Unit borders on three room surfacesConversion of sound power level to sound pressure levelSchallpegelgifferenz Sound level difference ΔL=LW - LP - LP [dB] [dB]0510121520253035Gerät Unit borders grenzt on an three drei Raumflächenroom surfacesFreifeldFr. fieldGerät Unit grenzt borders an on zwei two Raumflächenroom surfacesUnit is mounted at any point in the middle of a surfaceGerät ist frei in der Mitte einer Fläche0,5 1 2 3 4 5 6 8 10 15 20 30 40 60 70Distance Abstand from von the der sound Schallquelle source [ m [m] ]2 4 8Direction Richtungsfaktor factorFactories and swimming pools bathsFabrik- u.

GEA Cassette-Geko Fan Coil UnitNR and NC Limiting CurvesLimiting curvesIf narrower frequency components or outstanding single toneswith high intensity peaks occur in a broad frequency range (e.g.on a fan), the dB(A) specification (sum level) is not sufficient as itdoes not sufficiently address the annoying nature of the noise.Thus, for the purposes of noise evaluation, so-called limitingcurves (curves which produce the same level of inconvenience)are added that also take the combination of frequencies in thenoise into account.Although various noise-rating curves exist, NR (Noise Rating)curves as per Fig. 30-2 have become accepted internationally.NC curves (Noise Criteria) are now only used for noise rating inthe USA as per Fig. 30-3.If the observance of a particular NR or NC limiting curve isrequired for a room, the measured sound pressure must notexceed this limiting curve in any octave.The sum level across all eight octaves as per DIN is alwaysaround 7 to 10 dB higher than the limiting curve value. In the caseof air treatment units, the difference of the sound pressure levelin the medium is 5 dB(A) because the spectrum of these soundsdoes not always reach the same limiting curve in all octaves.Sound Schalldruckpegel pressure in level dB in dB9080706050403020ISO NR NR-Bewertungskurvenevaluation curvesNR 807060504030NR281020ExampleThe requirement of NR 28 or NC 26 must be observed.The basis is the tabulated data from page 28. In order to identifythe sound pressure level in the individual octaves, the soundpower values should be entered for Single, capacity stage 1 andspeed 2 in a table, see Table 2.In order to obtain the sound pressure levels in the individualoctaves, the value of 12 dB calculated on page 36 must besubtracted from the sound power specifications entered inTable 2. The new values attained can be entered in thenomograms Fig. 17 (NR) or Fig. 18 (NC).The highest point in the NR evaluation is NR 26 (1000 Hz) andNC 24 (1000 Hz) in the NC evaluation.The requirement of NR 28 (NR 26 is below NR 28) or NC 26(NC 24 is below NC 26), is thus maintained.Octave medium frequency for Single type,capacity stage 1 and speed 263 125 250 500 1000 2000 4000 8000 [Hz]35 48 48 42 35 29

GEA Cassette-Geko Fan Coil Unit Accessories / Primary Air SupplyThe GEA Cassette Gekos each have 2 air distribution openings in theunit side walls (See Fig. 32 and Fig. 33 for size and position).These make it possible to install ducts by others (e.g. DN150 flexiblepipe) in order to be able to transfer supply air to distant parts of theroom, or even neighbouring rooms.In this case, the unit's own air vanes can remain opened or be closed.SingleHowever, note that the number of air outlets used willaffect the air volume flow and pressure at each air outlet.Refer to the graphs below for the resulting air volumeflows through these air outlets, which are dependent onthe pressure differences in the duct system provided byothers.The graphs apply to the maximum speed of the units.Layout:With regard to the air-flow layout of the units, it should beassumed that the use of air outlets does not affect the totalair volume flow of the units.

The controller can be integrated into the followingsystem types:– 2-pipe “heating only” systems– 2-pipe “cooling only” systems– 2-pipe “heating or cooling” systems (change over)– 4-pipe “heating and cooling” systemsThe speed can be set manually and the unit switched off via the control panel. Valveswith on/off or modulating control behaviour and a supply voltage of 230 V AC can beactivated to control the heating and/or cooling capacity.Additionally, the MATRIX 500 enables monitoring of the fan motor via thermalcontacts with external leads as well as the condensate water level for cooling unitswith a condensate pump. The connected sensors are monitored as well.The OP5 control panel enables the setpoint values to be set quickly and easily withoutextensive prior experience. Mechanical limit stops can be used to limit the settingrange for the setpoint temperature and speed stage. Room temperature is measuredvia a sensor integrated in the control panel. If the control panel is positioned in anunfavourable location (such as by the door), an external temperature sensor or returnair sensor can be connected (not possible on changeover systems). System faults aresignalled centrally via the red “malfunction” LED. If economy mode is activated, it isdisplayed via the yellow LED integrated into the button.In addition to protection type IP20 (OP5 C), an IP54 control panel model (OP5 I) isavailable for moist areas.The connection in the unit is made via plug-in cage clamps. Electronics, fans andvalves (230V) are fused separately via two microfuses on the power supply. A prefuseof B 10A type must be supplied to provide the necessary circuit protection.The MATRIX 500 can be used for controlling individual recirculating air units and alsorecirculating air unit groups.54 PR-2010-0107-GB • Subject to modifications • Status 06/2011

Direct tapping is notpossible.The OP5 control panel enables the setpoint values to be set quickly and easily withoutextensive prior experience. Mechanical limit stops can be used to limit the settingrange for the setpoint temperature and speed stage. Room temperature is measuredvia a sensor integrated in the control panel. If the control panel is positioned in anunfavourable location (such as by the door), an external temperature sensor or returnair sensor can be connected (not possible on changeover systems).

Electronics, fans andvalves (230V) are fused separately via two microfuses on the power supply. A pre-fuseof B 10A must be supplied to provide the necessary circuit protection.The MATRIX 2000 can be used for controlling individual recirculation air units and alsorecirculation air unit groups. The integrated MATRIX.Net bus system enables integrationof up to 16 several groups to one network. The combination with MATRIX 3000controllers and connection of Global Modules and communication intefaces is alsopossible.MATRIX 3000The Matrix 3000 control system is based on the MATRIX 2000 system and providesadditional functions. The main functions are as follows:Valves with modulating control behaviour can be applied on 4-pipe systems. Mixedoperation is also possible (on/off cooling valve / modulating heating valve ormodulating cooling valve / on/off heating valve).Operation and error messages are output via two change-over contacts on the unit.The maximum load on the contacts at 230 V AC is 4 A ohmic / 2 A inductive.The supply air temperature can be limited for heating and cooling demand. Fixed andsliding limits can be defined.An external temperature sensor or recirculation air sensor can be connected to allsystem types.An additional control input enables the following operating modes to be definedexternally:– Normal / economy modeor– Unit OFF with frost protectionVarious types of control panels are available.
