APPLICATION CONSIDERATIONSAPPLICATION CONSIDERATIONSAPPLICATION CONSIDERATIONSAPPLICATION CONSIDERATIONS The general design intent of an Active Chilled Beam system is for the central system to circulate only the amount of primary air needed for ventilation and latent load purposes, with the Active Chilled Beams providing the additional sensible cooling (and heating) and air movement required through the induced room air and secondary water coil. Active Chilled Beam systems transfer a large portion of the cooling (and heating loads) from the less efficient air distribution system (fans and ductwork) to the more efficient water distribution system (pumps and pipes). The net result of this shift in loads is lower energy consumption and operating costs.

Primary Air SystemPrimary Air SystemPrimary Air SystemPrimary Air System There are a number of important issues affected by the primary airflow rates, pressure and temperature chosen in the primary air system design as follows:

• Ventilation Air Requirements

• Primary Air Latent Cooling Capacities

• Risk of Over-cooling/Reheating

• Building Pressurization Control Choosing the primary air flow rates and temperature requires considerable thought and judgment. Decreasing the primary air temperatures offers the opportunity to decrease fan energy consumption (within the limits of the ventilation air requirement) and increasing latent cooling capacities, while potentially increasing the risks of over-cooling/reheating. Other design concerns with the primary air system design include:

• Air Handler/Ductwork Zoning and Resetting of Primary Air Temperatures

• Air Distribution Considerations

• Noise Level Requirements

• Heating

Secondary Water SystemSecondary Water SystemSecondary Water SystemSecondary Water System The chilled water temperature entering the Active Chilled Beam secondary water coils must be at or above the room design dew point temperature to avoid formation of condensate on the coil. Using the room design temperature of 24 ºC db/ 17ºC wb (50% relative humidity), the room air dew point temperature is 12.8 ºC. In this case the minimum entering chilled water temperature to the Active Chilled Beams should be 12.8 ºC or higher (typically around 14-16 ºC is used in Practice). Choosing the secondary chilled water temperature is another area requiring considerable thought and judgment. A higher chilled water temperature will add to the margin of safety relative to condensation concerns and increase the hours when a water-side economizer can be used to serve the active chilled beams, but could have the effect of increasing the fan and pump energy requirements and unit costs.

HeatingHeatingHeatingHeating The suitability of the use of overhead heating from the ceiling in any system (Active Chilled Beam, VAV, etc) is dependent on the extent of heat losses along the perimeter. In general overhead heating is acceptable if the heat losses are less than 384 W/linear meter along the perimeter. The air distribution discharge arrangements employed vary based on the extent of heat losses along the perimeter.

UNIT SELECTIONUNIT SELECTIONUNIT SELECTIONUNIT SELECTION There are two methods for selecting DADANCO Active Chilled Beams – a manual method using the enclosed tables and an optimized design method using the DADANCO Specifier™ computerized product selection program. The following will demonstrate the manual selection method using the data from the Quick Selection Capacity and Sound Level tables. For optimized unit selections using the DADANCO Specifier™ computerized product selection program or for special selection assistance, contact Dadanco LLC via phone (413) 564—5657, fax (413) 568—5384 or e-mail at [email protected].

MANUAL SELECTION METHODMANUAL SELECTION METHODMANUAL SELECTION METHODMANUAL SELECTION METHOD

The unit performance data in the Quick Selection Capacity tables in this publication is given for the ACB35 (vertical down discharge) concealed ceiling-mounted model in both 2-pipe and 4-pipe coil configurations. The capacity ratings are based on a “typical” nozzle selections. With the optimized design method using the DADANCO Specifier™ computerized selection program, both the size/number of nozzles will vary and will be optimized to provide the exact performance required.

Ventilation AirVentilation AirVentilation AirVentilation Air To begin your unit selections determine the minimum ventilation air required for each zone (using as a minimum that prescribed by ASHRAE 62). This would be the minimum amount of primary air that could delivered to the Active Chilled Beams in each zone.

Latent Cooling Latent Cooling Latent Cooling Latent Cooling Prior to selecting the Active Chilled Beams the primary air quantity and temperature must be determined to provide for adequate ventilation air, as well as for the latent cooling capacity required. It is very important that both of these requirements are determined and satisfied by the primary air in every zone before selecting the Active Chilled Beams. Using the ventilation air quantity as the primary air quantity, determine the latent cooling being provided by the primary air based on the airflow, room design and primary air temperatures chosen. Compare the latent cooling capacity being provided by the primary air to the latent load in each zone. Often times the primary air quantity and temperature will be driven by the latent cooling loads and more (or preferably colder/drier) primary air will be required than that needed solely for ventilation air purposes to satisfy the zone latent loads. Remember that the latent loads in an Active Chilled Beam system must be fully satisfied by the primary air as insufficient latent cooling capacities can lead to condensation issues.

Quick Selection Cooling and HeatingQuick Selection Cooling and HeatingQuick Selection Cooling and HeatingQuick Selection Cooling and Heating Capacity TablesCapacity TablesCapacity TablesCapacity Tables The performance data in the Quick Selection Capacity tables are based on assumed operating conditions of:

• 125 Pa inlet static pressure

• 24 °C db/17 °C wb room design temperature (50% relative humidity, 0.00925 kg Water/kg Dry Air humidity ratio)

• 12.0 °C db/11.3 °C wb primary air temperature (90% relative humidity, 0.00800 kg Water/kg Dry Air humidity ratio)

Sensible CoolingSensible CoolingSensible CoolingSensible Cooling The Quick Selection Cooling Capacity tables show the sensible and latent cooling capacity being provided by the primary air, the sensible cooling capacity being provided by the secondary water coil and the total unit sensible cooling capacity.

Example Assume we want to select an ACB35 2-pipe unit and that the total sensible cooling capacity required was 1,350 W with a minimum primary airflow of 28 L/s. Using the correct Quick Selection Cooling Capacity table on page 7, a total sensible cooling capacity of 1,369 W (412 W from the primary air and 957 W from the secondary water coil) could be provided by a 1500 mm unit using 28 L/s of primary air. Remember this amount of primary air must be sufficient to provide the necessary ventilation air and latent cooling capacities required. The performance data in the Quick Selection Cooling Capacity tables is based on TRA — TPA of 12 °C (24 ºC — 12 ºC). Use the correction factor for primary air temperature less room design temperature differences other than the 12 °C ∆T temperature difference used in the Quick Selection Cooling

Capacity tables.

Example Using the above base unit selection, the sensible cooling being provided by the primary air is 412 W. If the primary air temperature was 11 °C (rather than the 12 º C assumed in the tables), the actual temperature difference is 13 °C (rather than the 12 °C used in the tables). The corrected sensible cooling capacity of the primary air at the 13 °C ∆T is 445 W ( 412 W x 1.08). The performance data in the Quick Selection Cooling Capacity tables is based on a TRA — TCHW of 10 °C ∆T (24 ºC — 14 ºC). Use the correction factor for room design temperature less chilled water temperatures other than the 10 °C ∆T temperature difference used in the Quick Selection Cooling Capacity

tables.

Example Using the above base unit selection, the sensible cooling capacity being provided by the secondary water coil is 957 W. If the chilled water temperature was 15 °C (rather than the 14 ºC assumed in the tables), the actual temperature difference is 9 °C (rather than the 10 °C used in the tables). The corrected sensible cooling capacity of the secondary water coil at the 9°C ∆T is 861 W (957 W x 0.90). Remember that the chilled water temperature must be above the room dew point temperature to avoid condensation issues.

Throw and Sound LevelsThrow and Sound LevelsThrow and Sound LevelsThrow and Sound Levels Consult the Throw and Sound Level tables to ensure proper air distribution and noise levels within each zone. Use conventional air distribution application guidelines when considering placement of the Active Chilled Beams. Throw performance will be determined depending on the supply air outlet diffuser chosen for use with the ACB35.

HeatingHeatingHeatingHeating The Quick Selection Heating Capacity tables show the sensible heating being provided by the primary air, the sensible heating being provided by the secondary water coil and the total unit sensible heating capacity. Remember that if the primary in the heating mode is being delivered at a temperature below the room design temperature, the heating required to bring the primary air up to the room design temperature must be added to the heating load that must be satisfied by the Active Chilled Beam’s secondary water coil.

Example Using the same base unit selection and the correct Quick Selection Capacity table on page 8, the unit would provide a total sensible heating capacity of 2,242 W (-343 W from the primary air and 2,571 W from the secondary water coil) using 28 L/s of primary air (based on the operating condition assumptions used in the Quick Selection Heating Capacity tables). The performance data in the Quick Selection Heating Capacity tables are based on a room design temperature less primary air temperature of 10°C ∆T temperature difference (22 ºC — 12 ºC). For primary air temperatures other than the 12 ºC adjust the amount of heating being provided by the primary air using the formula of:

QPA = 1.226 x PA x (TPA – TRA)

Example Using the above base unit selection, the sensible heating being provided by the primary air is –343 W. If the primary air temperature was 18 °C (rather than the 12 º C assumed in the tables), the corrected sensible heating capacity of the primary air is –137 W. The heating provided by the active chilled beam would increase to 2,434 W (-137 W from the primary air and 2,571 W from the secondary water coil). The performance data in the Quick Selection Heating Capacity tables is based on a THW—TRA of 28 °C (50 ºC — 22 ºC). Use the correction factor for hot water temperature less room design temperature other than the 28 °C ∆T temperature difference used in the Quick Selection Heating Capacity

tables.

Example Using the above base unit selection, the sensible heating being provided by the secondary water coil is 2,571 W. If the hot water temperature was 40 °C (rather than the 50 ºC assumed in the tables), the actual temperature difference is 18 °C (rather than the 28 °C used in the tables). The corrected sensible heating capacity of the secondary water coil at the 18 °C ∆T is 1,645 W (2,571 W x 0.64) and the active chilled beam heating capacity would decrease to 1,302 W (-343 W from the primary air and 1,645 W from the secondary water coil). WATER FLOW RATESWATER FLOW RATESWATER FLOW RATESWATER FLOW RATES The cooling and heating capacities shown in the Quick Selection Capacity tables are based on water flows rates of 0.10 L/s. Use the water flow correction factor for water flow rates other than 0.10 L/s.
