EC-Technology: Keyword Energy Efficiency GEA Cassette-Geko Fan Coil Unit


What are EC motors?EC-motors (= electronically commutated motors) are DC motors, where the rotor is not performed as a coil, like in usual AC motors, but consists of a permanent magnet. Electronic control of the motor enables continuous opera-tion, where the integrated electronics ensures alternating magnetic field which adjusts itself to the relevant speed (refer to Fig. 11). As compared to mechanical commutat-ing (brushes), there are no moving regulation components that generate additional losses.In such a way the motor operates at optimal conditions, re-sulting in maximum torque and minimum losses. The effi-ciency rate of the EC motors used by GEA is twice as high as the comparable AC motors. The application of this tech-nology in GEA fan coil units makes it possible to achieve high efficiency rates for fan motors - especially in part-load mode.

Fig. 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%.

Further aspects: Continuous operation Low generation of heat Established and usual high motor quality Same design for 50 and 60 Hz

Continuous GEA MATRIX controls

EC fans featuring continuous operation mode offer a few of benefits: Room temperature control is performed with a higher accuracy, because occurring

temperature 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 and cooling medium. Example: season-related different inlet temperature of heat gen-erator or 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 rapid increase of motor RPM and thus electrical power consumption.

With continuous speed regulation - "hard" fan speed changes are eliminated, which provides additional acoustical comfort.

The GEA MATRIX controls uses these features by making the following functions available, 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 (mute function) in order to prevent an acoustic overshoot in automatic mode. This upper RPM limit 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 switch between 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 others using MATRIX.PC.

EUROVENT Energy Label

Within the framework of EU regulations (Eco-Design Directive) clear limits will be set in 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 to include 7 energy efficiency classes (A to G) in January 2011.

In this case the energy efficiency is composed of time-weighted relationship between cooling 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, react with adjusted fan speed must consider the time share of the corresponding speed stages for the evaluation of energy efficiency. For the description of time-connected relationships EUROVENT uses coefficient A (maximum), B (medium) and C (minimum speed). These indicators vary, depending on heating or cooling operation mode.

The energy efficiency relationship is composed of time-weighted shares and ispresented in the examples using the following formulas:

Cooling (FCEER):

Heating (FCCOP):

with QK = Total cooling capacity

mit QH = Heating capacity

mit Pe = Electrical power consumption of fan

Higher numerical value of these indicators stands for especially outstanding energy efficiency.

Fig. 16

Sound pressure level dB(A)The sound pressure specifications in the tables on pages 6-25 and 28 apply to the reverberant sound field of a room with a volume of 100 m3 and a reverberation time of 0.5 s.To determine the anticipated sound pressure level at the installation location, refer to theA-rated sound power level in conjunction with the conversion diagram in Fig. 16.Example:Three Cassette Gekos of type GCS1 are to be installed in a conference room with dimensions (20 x 10 x 4m). They are to be operated at stage 2, i.e. the sound power level should be 43 dB(A), see p. 28.Determining the sound pressure level1. Based on the room volume (800 m3), absorption surface of approx. 100 m2 Sabin is estimated in accordance with the diagram in Fig. 16 Homes, offices, hotel rooms, conference rooms.2. The mean distance to the Cassette Gekos is assumed to be approx. 3 m and the direction coefficient to be 2, Fig. 15. The intersection of the dotted sample lines in the diagram inFig. 12 produces the sound level difference: L~12 dB3. The anticipated A-rated sound pressure level LP for a unit is thus:LP = LW L = 43 dB(A) 12 dB = 31 dB(A)According to Fig. 14, appr. 4.5 dB.

The anticipated sound pressure level in the room is thus:LPges. = LP + 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) guide values from VDI 2081

Tab. 1* = minimum requirements** = increased requirements

1) Also see applicable building regulations, DIN standards and VDI guidelines (e.g. DIN 4109, DIN 1946, VDI 2058); 2) Depending on use

GEA Cassette-Geko Fan Coil Unit NR and NC Limiting Curves


Limiting curvesIf narrower frequency components or outstanding single tones with high intensity peaks occur in a broad frequency range (e.g. on a fan), the dB(A) specification (sum level) is not sufficient as it does not sufficiently address the annoying nature of the noise. Thus, for the purposes of noise evaluation, so-called limiting curves (curves which produce the same level of inconvenience) are added that also take the combination of frequencies in the noise 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 in the USA as per Fig. 30-3.If the observance of a particular NR or NC limiting curve is required for a room, the measured sound pressure must not exceed this limiting curve in any octave.The sum level across all eight octaves as per DIN is always around 7 to 10 dB higher than the limiting curve value. In the case of air treatment units, the difference of the sound pressure level in the medium is 5 dB(A) because the spectrum of these sounds does not always reach the same limiting curve in all octaves.

ExampleThe requirement of NR 28 or NC 26 must be observed.The basis is the tabulated data from page 28. In order to identify the sound pressure level in the individual octaves, the sound power values should be entered for Single, capacity stage 1 and speed 2 in a table, see Table 2.In order to obtain the sound pressure levels in the individual octaves, the value of 12 dB calculated on page 36 must be subtracted from the sound power specifications entered inTable 2. The new values attained can be entered in the nomograms Fig. 17 (NR) or Fig. 18 (NC).The highest point in the NR evaluation is NR 26 (1000 Hz) and NC 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.

Necessary clear opening in the intermediate ceiling

Depending on the selected section in the intermediate ceiling - the installation of the design panel requires a shadow gap of around 4 mm running around the entire perimeter (for variant 1 - see Fig. 24), that can optionally be filled with a standard enclosed sealing strip (for variant 2, see Fig. 24), or the design panel directly contacts the ceiling(for variant 3, see Fig. 25).
