1. GENERAL INFORMATION1.1 APPLICATIONS

ESTEBH high pressure ducted fan coils with energy saving motors, are specifically designed for ducted installations, with external static pressure up to 300 Pa.Their high pressure fan decks permit to satisfy every request of heating and cooling application in big environments.

1.2 OPERATION

The effectiveness of a fan coil is due to the large surface area of the finned heat exchanger (coil) where the air drawn from the room by the fan passes through.Heating operation: the hot water circulating in the finned coil supplies heat to the air passing through the heat exchanger.Cooling operation: the chilled water circulating in the finned coil removes heat from the air passing through the heat exchanger.The air is also dehumidified and the condensed water vapor must be discharged from the unit: suitable drains must therefore be provided to drain the condensed water that collects in the condensate tray.

1.3 PERFORMANCES

The performance of a fan coil can vary greatly with changes in the temperature and in the amount of water circulating through the coil, as well as with changes in the temperature and in the amount of air circulating through the coil.The air volume is determined by selecting the proper fan speed through continuous regulation (0-100%) by using electronicor digital (OMNIBUS) regulators (also for BMS system) while the water flow rate is determined by the specifications of the system and of the pump.Thermal performances of the unit can be optimized by controlling the inlet flow rate of the water with proper regulating valves (ON/OFF or modulating), which can be supplied as accessories and which are necessary in case of cooling operation.For each model, thermal performances in heating and cooling depend on the number of rows of the coil installed, which gives the opportunity to make the air treatment suit every condition required.In cooling function, under the same operating conditions, the more rows the heat exchanger has, the more it will dehumidify.

1.4 PRODUCT RANGE

The ESTEBH high pressure fan coil units are available in 5 sizes (020÷060) for concealed horizontal installation, in 2 and 4 pipe systems.

1.5 SELECTION SOFTwARE

To facilitate choosing the correct size of a fan coil for any operating condition (including those differing from the standard ones), EURAPO offers a dedicated computer program which can be downloaded from the ftp address http://ftp.eurapo.it/ and can be updated with automatic upload through internet.

Installation and Operation instructions concerning the software for selection are provided with the software itself.

3. COMPONENTS

3.1 STRUCTURE

The structure is made of galvanized steel. A particular manufacturing process gives stiffness to the structure: in this way all risks of vibration (which causes unpleasant noise) are strongly reduced. All the inner elements that could be cooled are completely lined with insulating material based on polyolefins, chemically reticulated and closed cell foam, which is not only a thermal insulation material but also a good sound attenuator. Self-extinguishing grade in accordance to norms: Class 1 - Italy, Class M1 - France, UNI 8457 and UNI 9174.In order to facilitate all maintenance operations, the structure is divided in 3 separate and independent sections:

• Fandeck• Condensatetray• Filter

The air intake and outlet are provided with a 21 mm flange for an easy connection to the air duct.The ESTEBH fan coils can be installed on the ceiling by using the four fixing brackets always supplied with every unit.

3.2 COILS

For each unit size there are 2, 3 and 4 row coils available; for 4 pipe systems it is possible to install a 2 or 3 row coil. It is therefore possible to have a combination of maximum 7 rows (4 row cooling + 3 row heating). For models 060 are also 5 row coils available, which can be combined with additional 2 or 3 row coils. All coils consist of 3/8” external diameter copper pipes mechanically expanded to the aluminum fin packs, provided with copper headers and brass soldering connections. Max. operating pressure 1,6 MPa, testing pressure 2,8 MPa. For the sizes 020, 030, 040 e 050 each header is provided with a very handy air valve, to allow air venting or water drainage from the coil. The air valve can be easily reached from the outside of the unit. For the sizes 060 the air vent valve are not present, therefore it is necessary to provide in the pipe connection a system for the water discharge and air venting of the coil. ESTEBH units are also available for District Cooling applications: the water coils (4 rows for size 020÷050 and 5 rows for size 060) are designed with a reduced number of circuits, suitable for functioning with high water temperature difference.ESTEBH units can be ordered with right (standard) or left water connections, so defined when facing the air outlet. If necessary, however the coils can be easily removed and reversed on site. Water connections are 1/2” F (female threaded) for sizes 020, 030, 040, 050 1” M (male threaded) for size 060.

MAXIMUM OPERATING PRESSURE wITH vALvES: 16 BAR.

3.3 FAN DECk

The fan deck is composed by a motor and 2 centrifugal galvanized steel scrolls. The brushless motor is a component of the EST technology (Energy Saving Technology) applied to the Eurapo product range. It is combined to a dedicated electronic device (inverter), which is provided with DIP SWITCH that can be set on site accordingly to the pressure drop in the system. The inverter can be managed by specific regulators (Omnibus, for example) which use a modulating signal with 0-10Vdc tension in order to regulate the fan speed. OMNIBUS regulators give the possibility to fully control the fan speed (0-100%) and/or to manually select three fan steps (high, med and low speed): it is actually possible to set in every moment and very easily the three different levels of motor’s rotation, in order to fulfil specific thermal or acoustical requirements. The motor and the scrolls are fixed on a rigid galvanized steel 1,5 mm thick basement: the motor is located in a proper cradle and fixed with elastic ribbon supports. All motors operate at 50/60Hz and for all sizes the power supply is 230V± 6%. Each fan assembly is dynamically balanced, to reduce noise and wear of the components to minimum levels; it can easily be removed for maintenance operation.

The condensed water is discharged from both sides (left or right) through a 20 mm diameter header.Stainless Steel (AISI 316) condensate tray is also available upon request.

3.5 AIR FILTER

The air filter consists of a washable polyester acrylic fiber, filtration class G3. A filter with higher filtering grade (F5) is also available upon request for each model.The particular pleated shape of the filter, protected by a metal frame, allows having a big filtering surface with only 45 mm thickness. The filter section can be easily removed for cleaning and maintenance operation. Filters are not washable.

3.6 STANDARD ELECTRICAL PANEL IP30

All models are provided with a 12 pole terminal board with screw terminals contained in a self-extinguishing (class V0) plastic box (IP30).The electric box is fixed on the same side of the water connection.

7.5 wORkING OPERATION LIMITS

Each high pressure ducted unit can work properly only if the operating limits listed below are respected:

• Max.operatingpressure(waterside):1,6Mpa• Min.inletcoldwatertemperature:5°C• Max.inletcoldwatertemperature:20°C• Min.inlethotwatertemperature:35°C• Max.inlethotwatertemperature:85°C

In order to select the ESTEBH ducted fancoil with calculating conditions differing form the standard ones or with DISTRICT COOLING coils, please use the EURAPO software for selection.

Note. Some units can present the risk of condensing water sprays if selected under particular calculating conditions in water temperature and relative humidity. In this case it is necessary to modify the calculating parameters or select a different ESTEBH model.

Unit size 060 can be used only with external static pressure >30Pa. For a correct selection of the units, pls use the EURAPO software for selection.

8. NOISE LEvELS

8.1 SOUND POwER

The acoustic emission characteristics of any noise source is defined as its «sound power» (SWL). This typical measurement indicates the total radiated energy which does not vary for a given noise source; that is, it does not depend on the observer, location, distance or any other factor which is not part of the source. Following please find the values of the sound power level.

8.2 SOUND PRESSURE IN A CLOSED ENvIRONMENT

The perceived noise radiated from a sound source is something quite different: noise perception is indicated by its «sound pressure» (SPL). Even though it is caused by the emission of a sound energy, it greatly depends on the environment through which the sound travels, on the distance from the source and on all other circumstances that are not directly related to the primary noise source.Besides the distance from the source, the most important factor that influences the «sound pressure» (and, as a result, the perceived noise) in a closed environment is the amount of sound energy reflected off surfaces that have a greater or lesser reflection capacity: it depends, therefore, on the re-transmission of sound energy (power) acting upon reflecting surfaces.Covering the walls with sound absorbing material (i.e. material with a low sound reflecting capacity) is the most effective way to reduce the noise level in a closed environment.The following values indicate the sound pressure emitted by high pressure unit, calculated in open field at 1,5 meter distance and with a reverberation time of 0,3 seconds. By using the EURAPO software for selection it is possible to calculate the new sound pressure level obtained by changing the parameters: room volume, distance from the noise source and reverberation time.The reverberation time measures the sound characteristics of a room: it increases as the room dimensions increase and decreases as the sound absorption capacity of the structure increases.
