Samples for Capacity DefinitionGEA MPower-Geko Fan Coil UnitThe tables with capacity data on pages 6 to 12 indicated cooling and heating capacityas well as sound power level of the GEA MPower-Geko of modular configuration witha G2 filter and without mounted air side accessories and/or additional external staticpressure.A different unit configuration and using air side accessories like air intake and dischargeplenums or sound attenuation modules change internal and external air sideresistance. Air ducts and discharges connected by others can increase air side staticpressure drop that must be covered by the GEA MPower-Geko. In such a way the airflow rate of the unit decreases which results in reduced cooling and/or heating capacity.The sound level emitted in air ducts by others and via unit casing is also influencedby the size of air side resistance.The diagrams and tables given on pages 14 to 23 make it possible to calculate performancedata for such operating conditions that are different from "a least complicatedsituation".The following sample demonstrates the basic procedure:1: Pre-selection of unit size2: Determination of unit characteristics curve and actual operating point.3: Calculation of actual cooling and/or heating capacity4: If necessary - conversion of calorific output in other air/medium units5: Determination of actual sound power level6: Calculation of expected indoor sound pressure levelExample In an open plan office with a suspended ceiling of size 20 x 10 x 4 m 2 GEA MPower-Gekos in compact configuration are to be installed:Cooling load: 12 kW at air intake 27 °C/46 % r.h. and chilled water 6/12 °C (total indoor cooling load)Max. sound pressure level: 45 dB(A) as of VDI 2081Accessories: – 2 discharge cover caps DN200 (only 3 out of 5 connectors should be used)– Air intake sound attenuator– Intake flexible connectionFilter class: G3External static pressure 35 Pa at 1000 m³/h (per unit)drop:1. Pre-selection of unit size Based on the projected air flow rate of around 1000 m³/h and max. allowed sound levelunit size 3 in capacity stage 2 and speed 2 is selected. The following preliminary capacityis calculated:Air flow rate: 1000 m³/h at app. 40 Pa static pressure (refer to unit curve speed 2, page 20)Cooling capacity: 6,5 kW (refer to table „Overview of capacity for different operating points size 3“page 20)Sound power level: 48 dB(A) (refer to table „Sound power level with other operating points“ on page 21)**) Note: In this case only discharge related sound level is considered, because a sound attenuator is providedon the intake side.2. Determination of unitcurveExampleIn characteristics curve field on page 20 the curve of external static pressure drop isentered. The points of the curve can be calculated using the formuladp2 = dp1 * (V2/V1)².dp1 = 35 PaV1 = 1000 m³/hV2 = 1500 m³/hdp2 = 35 Pa * (1500/1000)² = 78,8 PaCharacteristics curves of additional unit internal pressure drops (capacity stage 2 andfilter class G3) and pressure drops of air side accessories (air intake sound attenuator,compact basic unit with 2 caps) are added up to „unit characteristics curve“ which is asum of all additional external and internal pressure drops.24 PR-2009-0015-GB • Subject to modifications • Status 10/2009

GEA MPower-Geko Fan Coil UnitSamples for Capacity DefinitionExampleThe task is to arrive at the sum of individual pressure losses at V = 1500 m³/hdp Capacity stage 2 = 5,0 Pa (as indicated on curve)dp Intake sound attenuator = 5,0 Pa (as indicated on curve)dp Filter class G3 = 12,5 Pa (as indicated on curve)dp Compact basic unit 2 caps = 19,5 Pa (as indicated on curve)dp External = 78,8 Pa (based on previous sample calculation)dp unit = (5,0 + 5,0 + 12,5 + 19,5 + 78,8) Pa = 120,8 PaThe intersection point of this unit curve with the unit curve of speed 2 is identical to theactual operating point of unit at speed 2.This results in air flow rate of around 980 m³/h (refer to Fig. 11).160140Unit characteristics curve120External static pressure drop100Speed 2Static pressure [Pa]806040Compact basic unit with 2 caps2009800 500 1000 1500 2000 2500Air flow rate [m³/h]Filter class G3Air intake attenuatorCapacity stage 2Fig. 11: Size 3 - curve field3.

Determination of actualsound power level of unit.The actual cooling capacity can be interpolated from table data on page 20. Thisresults in cooling capacity of around 6,4 kW.If projected air intake conditions and/or medium temperatures deviate from standardconditions (cooling: air intake 27 °C/46 % r.h., CWP 6/12 °C and heating: air intake20 °C, WWP 70/50 °C for heating), calorific capacity can be adjusted to other parametersusing conversion factors (refer to page 1.2).Using tables „Sound power level with different operating points“ (refer to page 21) thesound power level of the basic unit can be interpolated on air intake, discharge sideand acoustic emission of casing. Air flow rate of 980 m³/h at speed 2 results in thefollowing values:LW intake: approx. 47 dB(A)LW discharge: approx. 49 dB(A)LW casing: approx. 36 dB(A)Because a sound attenuator is mounted on the intake side, the acoustic insulation ofsound attenuator (ΔLW = ca. 10 dB intake side, refer to table „Acoustic insulation ofsound attenuator - sum level“, page 21) must be deducted from the previously calculatedvalue:LW air intake (sound attenuator): approx 37 dB(A)PR-2009-0015-GB • Subject to modifications • Status 10/2009 25

Samples for Capacity DefinitionGEA MPower-Geko Fan Coil Unit6. Calculation of expectedindoor sound pressurelevelTables on pages 6 to 13 (unit selection) and 16 to 23 (Overview of capacity) presentsound power level of basic units on air intake and discharge sides as well as unit casingacoustic emission. These data correspond to unit acoustic emission energy. In orderto determine actual sound level perceived by human ear at a certain point indoors,different factors need to be considered.Sound energy emitted in the air ductwork by others is usually absorbed (= reduced)thanks to absorption and reflection process. The manufacturer usually provides informationon certain components, e.g. acoustic insulation of a sound attenuator. Otherinfluencing factors can be e.g. material and form of air ducts, form and number of crosssection changes, duct ramifications, etc. As a rule, these can be estimated based onthe empirical data of the manufacturer.Sound energy emitted by unit casing in room direction is usually reduced only by thesuspended ceiling. In this case material type and ceiling thickness as well as possiblyused addition insulating material of suspended ceiling play a key role (e.g. mineral woolcoating).Supply and exhaust air flow entering and leaving the room through air ducts generatesflow noise, that to a great extent depends on the used product (refer to manufacturerspecifications). If the difference between sound level before the air duct opening andspecific sound level of duct opening amounts to more than 10 dB, the increase of thetotal level is to be neglected. If the difference is smaller - the level with a higher figuremust be increased by the level difference which is calculated according to the followingformula:Δ L = 10 * log (1+10^(L 1 -L 2 )/10)In our example it is assumed that only one duct opening is used for each unit and thespecific sound level difference exceeds 10 dB.In order to define the anticipated indoor sound pressure level - the previously calculatedA-rated sound power level is used in connection with a conversiondiagram Fig. 12.Conversion of sound power level in sound pressure levelSound Schallpegeldifferenz level difference ΔL=LW - LP - LP [dB] [dB]0510121520253035Fig. 12Unit Gert borders grenzt with an drei three Raumflchen indoor surfacesFreifeld0,5 1 2 3 4 5 6 8 10 15 20 30 40 60 70Abstand Distance von der from Schallquelle sound source [ m ] [m]FreeUnit Gert borders grenzt with an zwei two Raumflchenindoor surfacesGertist Unit mounted frei in der free Mitte in einer the middle Flcheof a surface2 4 8Direction RichtungsfaktorcoefficientFactory halls and swimming poolsFabrik- u.

The mean distance to the duct opening is assumed to be approx. 3 m and the directioncoefficient to be “2”, Fig. 13. The intersection of the dotted sample lines in the diagramFig. 12 mounts to the sound level difference: ΔL~12 dB.Direction coefficient 2(hemispherical radiation): unit is mounted free in the middle of a surfaceDirection coefficient 4(quarter-spherical radiation): unit borders with two room surfacesDirection coefficient 8(eight-spherical radiation): unit borders with three room surfacesSound level increase in dB1098765432112 3 4 5 6 8 10Number of unitsFig. 14: Sound level increase (dB)3. The anticipated A-rated sound pressurelevel L P for a unit is thus:L P = L W – ΔL = 49 dB(A) – 12 dB = 37 dB(A)Sound level in case of 2 discharge openings increases according to thediagram Fig. 14, by approx. 3 dB.Thus, the anticipated sound pressure level in the room amounts to:L Pges. = L P + 3 dB = 37 dB(A) + 3 dB = 40 dB(A)The approximate value for increased requirements (large office 45 dB (A) in table Fig.15) is thus fulfilled.Table „A-sound pressure level“ LP 1 as approximate value according to VDI 2081Room type A-sound level [dB(A)] Mean reverberation time [s]Apartment * **(Hotel room) night 35/30 30/25 0.5Residential rooms day 35 30 0.5AuditoriumsTV studio 30 25 1.5Concert halls 30 25 2.0Operas 30 25 1.5Theatre 35 30 1.0Cinema 40 30 1.0Lecture halls 40 35 1.0Reading rooms 40 35 1.0Seminar rooms 40 35 1.0Classrooms 40 35 1.0OfficesConference rooms 40 35 1.0Leisure rooms 40 35 0.5Break rooms 40 35 0.5Small offices 40 35 0.5Large offices 50 45 0.5Church 35 25 3.0Museums 40 35 1.5Service halls 45 40 1.5IT/Telecommunication room 55 40 1.5Laboratories 45 40 2.0Restaurants 40 to 55 2 1.0Kitchens 45 to 60 2 1.5Sales rooms 45 to 60 2 1.0Fig. 15* = Mimimum requirements** = Increased requirements1 Also refer to applicable building regulations, DIN standards and VDI guidelines (e.g. DIN 4109, DIN 1946, VDI 2058)2 Depending on applicationPR-2009-0015-GB • Subject to modifications • Status 10/2009 27
