For the energy efficient buildings of today and tomorrow Chilled Beam/Induction Unit All Way Blow Chilled Beam Technical Specifications American Owned and Operated
Chilled Beam/Induction Unit A Chilled Beam takes a source of primary air at a maximum inlet static pressure of 1 WC. It distributes this air through a bank of specially designed aerodynamic nozzles and discharges the air at a high velocity into a mixing chamber. This creates a differential pressure which enables a draw of room air across a coil. This imparts either sensible cooling or heating to the air as it passes over the coil. The primary air and induced air are mixed and discharged through a grille in a coanda effect air distribution at the ceiling. This air circulates throughout the room and is gently drawn back up through the return section of the Chilled Beam grille. Because the return air to the terminal is located at the ceiling and is moving so gently, dirt is not carried along with it and filters are not required to protect the coils. This eliminates the cost and labor required for this routine maintenance. Chilled Beams are extremely flexible and enhance the savings and effectiveness of primary air systems such as those using dedicated outside air. When using our Chilled Beams, the primary air system, which includes the dedicated outside air unit and the supply and exhaust ductwork, can be sized to handle only the required ventilation air. This reduces the size of the equipment and ductwork making it easier to fit into a building space. This also reduces the energy required to supply the ventilation to the building. The total room air circulation is created solely by the induction principle within the terminal; therefore, there is no electric motor requiring an electric power source or maintenance for a fan and motor. As a result, the Chilled Beam is a very quiet and efficient way to provide comfort in a space. Model MiniQ360 All Way Blow Ceiling Mounted Induction Unit The model MiniQ360 is a ceiling mounted Chilled Beam that blows in all directions and provides the very best in air distribution. These units are a smaller 2 x 2 version of the model Q360. They are 24 x 24 and fit neatly into a 2 x 2 ceiling grid. The MiniQ360 is supplied with a concentric supply/return diffuser. The MiniQ360 can handle between 60 an 150 CFM of primary air and is perfect for the smaller spaces that still require a multi directional blow. These units are available in 2- and 4-pipe configurations. These units have drain pans and are capable of doing both sensible and latent conditioning in the occupied space.

MiniQ360 Installation and Balancing Instructions INSTALLATION 1. Before opening the shipping carton that protects the MiniQ360, please inspect the packaging for signs of physical damage. Damage should be noted on Shippers Bill of Lading and report same to the shipper and to NuClimate Air Quality Systems. 2. The packaging for the MiniQ360 is made up of a base tray and an inverted box cover. Remove the box cover to fully expose the MiniQ360. There are four sides to the unit. This unit has an 4 round duct collar for connection to the primary air ductwork. The 2-pipe unit has one 3/4 FPT chilled/hot water supply connection and one 3/4 FPT chilled/hot water return connection. 3. When supplied, the flexible hose connections and valves are shipped separately. It is important to connect the supply water to the supply water connections and return water to the return water connections. These connections have been labeled for your convenience. 4. Each MiniQ360 unit has one 3/4 CPVC condensate pan connection. When not piping to a condensate drain, the unit will be supplied with a plug or a float switch (shipped separately). The float switch should be wired in series to the room controller to shut off the coil valve if sufficient condensate should build up. If multiple units are used in a single zone, these switches should be wired in series to the room controller. 5. There are two mounting brackets bolted to each side of the MiniQ360. These brackets will accept field supplied 1/4 all-
Port 3/4 FPT Return Connection 4 Round Duct Connection 3/4 FPT Supply Connection 3/4 CPVC Drain Connection thread rod to facilitate the hanging of this unit. These brackets can also be used for wire hanging systems such as Gripple. 6. The unit weighs approximately 90 pounds. Do not lift the unit by the drain pipes, water piping, or metal duct. It is suggested that all units be lifted using the mounting brackets. 7. Set the MiniQ360 on a cable lift or other lifting device to lift it above the ceiling level. Be careful to insure the lifting platform is wide enough to reach the outer shell of the MiniQ360. The center drain pan and coil should not and can not be used to support the unit. 8. To hang the unit, we recommend securing two Uni-Strut channels, 24 apart, to the building structure where the unit is to be hung. Secure two 1/4 all-thread rod about 20 apart on each channel so that they hang down to the top of where the MiniQ360 is to be hung. Raise the unit and screw the all-thread rod hanging from the building channels into the mounting brackets. The rod should be secured with a washer and lock nut. 9. Final elevation and horizontal adjustments can be made to align the unit with the diffuser. The mounting brackets have holes for the rod approximately every inch. The unit can be adjusted to meet the ceiling grid using these bracket holes, and by raising and lowering the unit to align with the ceiling by adjusting the nuts on the all-thread rod on the building channel. Prior to placing the unit in the ceiling grid, remove the two cotter pins that hold the supply/return section to the diffuser frame. CAUTION! (1) Failure to remove the cotter pins will prevent access to coils and internal workings of the MiniQ360 unit. (2) It is imperative that the unit and diffuser fit together tightly to insure proper system performance. 10. Attach the flexible hose piping assembly (if supplied) to the appropriate supply and return water connections of the unit. 11. A short section of insulated 4 flexible duct can be used to connect the primary air ductwork to the unit. Make sure that the flexible duct connection to the MiniQ360 is sealed air tight. A field supplied balancing damper should be provided in this primary air duct to facilitate the air supply balancing of each unit to the scheduled static pressure at the unit inlet. 12. The MiniQ360 unit is essentially maintenance free. We do recommend checking the coils once a year. To do this open the spring loaded diffuser portion of the grille. It is spring loaded to allow access by pushing from one side. Once the grille has been lowered check the coil for dust or debris. If any is present it can be removed with a shop vacuum. BALANCING PROCEDURE Background Chilled Beams are air induction devices that take the primary air source and direct this air through nozzles that create a lower pressure that draws room air over a coil. This induced air is then mixed with the primary air stream and is delivered through the grille to the room in a coanda air pattern. The amount of primary air each Chilled Beam takes is based on the inlet static pressure and all performance data has been tested. The Chilled Beams will function below and above these pressures but performance data has not been certified outside this range. Balancing Procedure To balance the air system for the Chilled Beams it is only necessary to adjust the inlet static pressure at each Chilled Beam to the values shown on the schedule for each room. The inlet static pressure should be read at the duct connection to each Chilled Beam. A static pressure tap is supplied on each Chilled Beam for a balancer to take their readings at. The capacity chart for the conditions of each project is included in our submittals and will show the primary air CFM, total CFM, sensible and latent capacities at each inlet pressure. This information varies linearly within the pressure range given and the air quantities can be interpreted safely within this range. Alternate Balancing Procedure If multiple Chilled Beams in a given space are not accessible to measure the static pressure at the inlet to each unit, they can be balanced as a group as follows: 1. Add up all the scheduled primary air to each Chilled Beam on a given primary air duct branch feeding a common area. 2. Adjust the damper to that branch to allow the primary air quantity determined above to the space. Since Chilled Beam units all operate linearly at static pressures between.4 to WC, all terminals on the primary air branch to a given space will operate at the common static pressure available in that branch duct that will produce the total primary air measured. 3. Total supply air is dependant on the primary air and static pressure at the unit. It can not be directly measured but is cataloged in our product literature.

The sample was tested in accordance with the ASHRAE 70-2006 standard Method of Testing for Rating the Performance of Air Outlets and Inlets, which incorporates ADC 1062: GRD-84 test code for grilles, registers, and diffusers. Acoustical data was obtained employing a Bruel & Kjaer digital frequency analyzer type 2131 and analyzed on a Compaq Prolinea 4/33 computer and Epson LQ-850 printer. The reference sound source used for this test was a calibrated Bruel & Kjaer type 4204, which conforms to the above standard. The octave band sound power levels were plotted on graph of Noise Criteria Curves which is in the ADC test code. These curves are reprinted with permission from the ASHRAE handbook and product directory, 1976. The sample was installed in the facility and supplied with measured volumes of air. The static pressure was measured 1 1/2 duct diameters upstream of the diffuser inlet. The sample was tested in general accordance with the ARI-410-2001 standard Forced-Circulation Air-Cooling and Air-Heating Coil. The sample was installed in the facility and supplied with measured volumes of air, measured temperatures of air and water, and measures GPM flow rates. The air static pressure was measured with the test samples built in pressure tap. Throw Terminal Velocity FT/MIN Room Ambient Temperature (Deg.
