Samples for Capacity Definition GEA MPower-Geko Fan Coil Unit


The tables with capacity data on pages 6 to 12 indicated cooling and heating capacity as well as sound power level of the GEA MPower-Geko of modular configuration with a G2 filter and without mounted air side accessories and/or additional external static pressure.

A different unit configuration and using air side accessories like air intake and dis-charge plenums or sound attenuation modules change internal and external air side resistance. Air ducts and discharges connected by others can increase air side static pressure drop that must be covered by the GEA MPower-Geko. In such a way the air flow rate of the unit decreases which results in reduced cooling and/or heating capac-ity. The sound level emitted in air ducts by others and via unit casing is also influenced by the size of air side resistance.

The diagrams and tables given on pages 14 to 23 make it possible to calculate per-formance data for such operating conditions that are different from "a least complicated situation".

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 level

Example 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: 8 kW at air intake 23°C/50 % r.h. and chilled water 6/12 °C (total indoor cooling load)

Max. sound pressure level: 45 dB(A) as of VDI 2081

Accessories: – 2 discharge cover caps DN200 (only 3 out of 5 connectors should be used)– Air intake sound attenuator– Intake flexible connection

Filter class: G3

External static pressuredrop:

35 Pa at 1000 m³/h (per unit)

1. Pre-selection of unit size Based on the projected air flow rate of around 1000 m³/h and max. allowed sound level unit size 3 in capacity stage 2 and speed 2 is selected. The following preliminary ca-pacity is calculated:

Air flow rate: 1000 m³/h at app. 40 Pa static pressure (refer to unit curve speed 2, page 20)

Cooling capacity: 4,1 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 pro-vided on the intake side.

2. Determination of unitcurve

In characteristics curve field on page 20 the curve of external static pressure drop is entered. The points of the curve can be calculated using the formuladp2 = dp1 * (V2/V1)².

Example dp1 = 35 PaV1 = 1000 m³/hV2 = 1500 m³/h

dp2 = 35 Pa * (1500/1000)² = 78,8 PaCharacteristics curves of additional unit internal pressure drops (capacity stage 2 and filter 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 a sum of all additional external and internal pressure drops.

GEA MPower-Geko Fan Coil Unit Samples for Capacity Definition


Example The 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 Pa

The intersection point of this unit curve with the unit curve of speed 2 is identical to the actual operating point of unit at speed 2.

This results in air flow rate of around 980 m³/h (refer to Fig. 11).

Fig. 11: Size 3 - curve field

3. Determination of actualcooling capacity

The actual cooling capacity can be interpolated from table data on page 20. This results in cooling capacity of around 4,0 kW.

4. Determination of actualsound power level of unit.

Using tables „Sound power level with different operating points“ (refer to page 21) the sound power level of the basic unit can be interpolated on air intake, discharge side and 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 of sound attenuator (ΔLW = ca. 10 dB intake side, refer to table „Acoustic insulation of sound attenuator - sum level“, page 21) must be deducted from the previously calcu-lated value:LW air intake (sound attenuator): approx 37 dB(A)

5. Calculation of expectedindoor sound pressure

level

Tables on pages 6 to 13 (unit selection) and 16 to 23 (Overview of capacity) present sound power level of basic units on air intake and discharge sides as well as unit casing acoustic emission. These data correspond to unit acoustic emission energy. In order

Samples for Capacity Definition GEA MPower-Geko Fan Coil Unit


to 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 infor-mation on certain components, e.g. acoustic insulation of a sound attenuator. Other influencing factors can be e.g. material and form of air ducts, form and number of cross section changes, duct ramifications, etc. As a rule, these can be estimated based on the empirical data of the manufacturer.

Sound energy emitted by unit casing in room direction is usually reduced only by the suspended ceiling. In this case material type and ceiling thickness as well as possibly used addition insulating material of suspended ceiling play a key role (e.g. mineral wool coating).

Supply and exhaust air flow entering and leaving the room through air ducts generates flow noise, that to a great extent depends on the used product (refer to manufacturer specifications). If the difference between sound level before the air duct opening and specific sound level of duct opening amounts to more than 10 dB, the increase of the total level is to be neglected. If the difference is smaller - the level with a higher figure must be increased by the level difference which is calculated according to the following formula:

Δ L = 10 * log (1+10^(L1-L2)/10)

In our example it is assumed that only one duct opening is used for each unit and the specific sound level difference exceeds 10 dB.

In order to define the anticipated indoor sound pressure level - the previously calcu-lated A-rated sound power level is used in connection with a conversiondiagram Fig. 12.

1. Based on the room volume (800 m3), an absorption surface of approx. 100 m2 Sabin is estimated in accordance with the diagram Fig. 12“Homes, offices, hotel rooms, con-ference rooms”.

2. The mean distance to the duct opening is assumed to be approx. 3 m and the direc-tion coefficient to be “2”, Fig. 13. The intersection of the dotted sample lines in the dia-gram Fig. 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 surfaces

3. The anticipated A-rated sound pressurelevel LP for a unit is thus:LP = LW – 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:LPges. = LP + 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“ LP1 as approximate value according to VDI 2081

Overview of Valves GEA MPower-Geko Fan Coil UnitShut-off Valves


The setting of the necessary medium flow rate is carried out on the basis of the following diagrams. The pre-setting corresponds to the number of rotations to the left of the setting/adjustment screw starting from the right stop position (valve closed).

All GEA valves can be optionally supplied with shut-off valves at the outlet.

These valves are used for shutting-off the cooling or heating medium as well as for adjusting and equalizing medium flow rate.

Depending on rated size of the control valve, shut-off valves are used with kvs-value of 1,45 or kvs-value 2,20.

Technical data:Rated pressure: 10 barMax. water inlet temperature: 130 °CpH-value: 8 - 9,5

As medium water with a max. 50% glycol rate is allowed.

Depending on the valve equipment the shut-off valves are supplied with outer thread connection (designation number „4“ in on page 51) or with connecting nut and solder fitting (designation number „5“, refer to Product type code on page 51).

GEA MATRIX Control System GEA MPower-Geko Fan Coil UnitSystem Description


MATRIX 500MATRIX 500 control system supports all basic functions (heating/cooling) of recircu-lating air fan coil unit. The controller can be used in the following unit types:– 2-pipe units „only heating“– 2-pipe units „only cooling“– 2-pipe units „cooing or heating“ (change over)– 4-pipe unit „cooling and heating“

The speed can be set manually and the unit switched off via the control panel. Valves with on/off or modulating control behaviour and a supply voltage of 230 V AC can be activated to control the heating and/or cooling capacity. Additionally, the MATRIX 500 enables monitoring of the fan motor via thermal contacts with external leads as well as the condensate water level for cooling units with a condensate pump. The connect-ed sensors are monitored as well.

The OP4/OP5 control panel enables the setpoint values to be set quickly and easily without extensive prior experience. Mechanical limit stops can be used to limit the set-ting range for the setpoint temperature and speed stage. Room temperature is meas-ured via a sensor integrated in the control panel. If the control panel is positioned in an unfavourable location (such as by the door), an external temperature sensor or re-turn air sensor can be connected (not possible on changeover systems). System faults are signalled centrally via the red “malfunction” LED and output using a change-over contact. If economy mode is activated, it is displayed via the yellow LED integrat-ed into the button. In addition to protection type IP20 (OP4 C/OP5 C), an IP54 control panel model (OP5 I) is available for moist areas.

The connection in the unit is made via plug-in cage clamps. Electronics, fans and valves (230V) are fused separately via two backup fuses on the power supply. A fuse of 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 recir-culating air unit groups as well.

MATRIX 2000

The MATRIX 2000 control system is based on features incorporated in the MATRIX 500 system but also provides additional functions that can be summarized as follows:– Along with manual speed selection the fan control can be also carried out in a 3

speed mode based on the deviation of actual temperature from the setpoint.– With 2-pipe units 3-point modulating valve actuators can be controlled as well.– Besides, the control of valve actuators using 24V AC supply voltage is also

possible (transformer by others).

The direct connection of an external room temperature sensor is not possible with change over units, but can be performed via a Global Module. A fault message can also be received using a Global Module. Direct tapping is not possible.

GEA MPower-Geko Fan Coil Unit GEA MATRIX Control System System Description


The OP20/OP21 control panel enables the setpoint values to be set quickly and easily without extensive prior experience. Mechanical limit stops can be used to limit the set-ting range for the setpoint temperature and speed stage. Room temperature is meas-ured via a sensor integrated in the control panel. If the control panel is positioned in an unfavourable location (such as by the door), an external temperature sensor or return air sensor can be connected (not possible on change over systems please use a Glo-bal Module). System faults are signalled centrally via the red “malfunction” LED. If economy mode is activated, it is displayed via the yellow LED integrated into thebutton.

In addition to protection type IP20 (OP20 C/OP21 C), an IP54 control panel model (OP21 I) is available for moist areas.

The connection in the unit is made via plug-in cage clamps. Electronics, fans and valves (230V) are fused separately via two microfuses on the power supply. A backup fuse B 10A must be supplied to provide the necessary circuit protection.

The MATRIX 2000 can be used for controlling individual recirculation air units and also recirculation air unit groups. The integrated MATRIX.Net bus system enables integra-tion of up to 16 several groups to one network. The combination with MATRIX 3000 controllers and connection of Global Modules and communication interfaces is also possible.

MATRIX 3000The Matrix 3000 control system is based on the MATRIX 2000 system and provides additional functions that can summarized are as follows:3-point valves with modulating control behaviour can be applied on 4-pipe systems. Mixed operation is also possible (2-point cooling valve / modulating heating valve or modulating cooling valve / 2-point heating valve).Operation and fault signals 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. Fixed and sliding limits can be defined.An external temperature sensor or return air sensor can be connected to all system types.An additional control input enables the following operating modes that can be set externally:– Normal/economy operation or– Unit OFF with frost protectionVarious types of control panels are available. The range varies from a simple variant with setpoint temperature and fan operating mode selection using infrared remote control to a control panel with display. The display unit can also be supplied with an integrated weekly timer.

MATRIX 4000

The Matrix 4000 control system is based on the MATRIX 2000/3000 system and pro-vides additional functions that can summarized are as follows:

In order to provide improved selection of heating/cooling capacity a five speed fan control is enabled.

For applications with highest comfort requirements electronic control elements pro-vide absolutely silent valve control.

Four additional control inputs enable external assignment of the following operating modes:– Normal mode– Economy mode– Free mode– Unit OFF with frost protection– Compulsory setting of a fan speed

A connection possibility for an outdoor sensor makes it possible to activate summer compensation. Outdoor air temperature value is automatically transmitted to all units connected within the MATRIX.Net.

GEA MPower-Geko Fan Coil Unit GEA MATRIX Control System Mounting Control Panels


As the control panel is split into two units, the control panel cover only needs to be snapped on the mounting plate during commissioning. This provides optimum protection against dirt and damage for the control panels during the construction phase.

The cable connection is established via cage clamps. This enables quick and easy use of solid and flexible cores.

To mount the control panel in a standard in-wall socket, corresponding drill holes need to be provided in the mounting plate.

The control panel can also be fitted directly on the wall (cable laid under plaster or in cavity wall).

IP54 control panels for moisture proof applications are available on request.

To prevent dirt accumulation or accidental operation, control panel covers are available as accessories (refer to Fig. 49 on page 46).

MATRIX.LON module

The MATRIX.LON communication module is part of the global modules of the GEA MATRIX control system and is used for connecting the MATRIX control system to a network structure in accordance with the LON WORKS standard. It enables the con-nection of air treatment components to a building management system or other facility management systems. It also enables external systems such as dampers or lighting systems to be controlled via the MATRIX OP50/51 control panel. The module can be integrated into the MATRIX network at any point.

MATRIX.Clock timer moduleThe MATRIX.Clock timer module is intended for use as a central weekly timer. The module can be integrated into the MATRIX network at any point and supports up to 16 groups in a network. The groups can be assigned individually to six weekly programmes, special switching days and the holiday programme. In each weekly programme, up to four switching times (2 x on / 2 x off) can be defined. Additionally, up to six special switching days with up to four switching times (2 x on / 2 x off) per special switching day can be defined. Holiday periods can be defined via the holiday days that can be programmed for the whole calendar year. Input is carried out via a straightforward “push&turn” control. Ease of user navigation is ensured by means of structured menus, plain text messages and pictograms. The current status of the individual programmes is displayed via a menu. The timer module can be toggled between six different languages online. The switch between summer and winter time is done automatically. If required, a blocking protection e.g. for pumps can be activated (once a week). Additionally, the time format can be selected between 12 and 24 hour display.Power to the clock timer is supplied via the MATRIX controller’s power unit..There are two different variants available:– MATRIX.Clock C with IP 20 protection type; colour – white (similar to RAL 9016)– MATRIX.Clock I with IP 54 protection type; colour – light grey (similar to RAL 7035)
