GEA Cassette-GekoSound Pressure Level, Sound Power LevelSound 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 the A-rated sound power level in conjunction with theconversion diagram in Fig. 14.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 ), anabsorption surface of approx. 100 m 2 Sabinis estimated in accordance with the diagram inFig. 14 “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. 13. The intersection ofthe dotted sample lines in the diagram inFig. 12 produces the sound level difference:∆L~12 dB3. The anticipated A-rated sound pressurelevel L P for a unit is thus:L P = L W – ∆L = 43 dB(A) – 12 dB = 31 dB(A)According to Fig. 12, 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 Fig. 29-1, 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. 12Direction coefficientsFig. 1312 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 ∆L=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 von from der the Schallquelle sound source [ m ] [m]2 4 8Direction Richtungsfaktor factorFactories and swimming poolsFabrik- u.

NR and NC Limiting CurvesGEA Cassette-GekoLimiting 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. 15 have become accepted internationally. NCcurves (Noise Criteria) are now only used for noise rating in theUSA as per Fig. 16.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 29 must besubtracted from the sound power specifications entered inTable 2. The new values attained can be entered in thenomograms Fig. 15 (NR) or Fig. 14 (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-GekoAir Distribution via External Air OutletsThe 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.However, 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.5040SingleLayout: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 circulating air units and alsocirculating air unit groups.46 PR-2007-0069GB • Subject to modifications • Status 08/2007

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.

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. The spectrum ranges from a simplevariant with setpoint temperature and fan operating mode selection using infraredremote control to a control panel with display. The display unit can also be suppliedwith an integrated weekly timer.PR-2007-0069GB • Subject to modifications • Status 08/2007 47
