What is an active chilled beam?

With active chilled beam systems the building's primary/ventilation air is continuously supplied to the active chilled beam terminal units by the central air handling system. This primary/ventilation air is cooled or heated to partially handle the temperature-driven sensible loads, while in the summer being cooled/dehumidified enough to handle all of the internal moisture-driven latent loads.

Primary/ventilation air (1) is introduced into the active chilled beam through a series of nozzles (2). This induces room air (3) up into the active chilled beam and in turn through a secondary water coil (4). Induced room air is cooled and/or heated by the water coil to the extent needed to control the room temperature. Induced room air is then mixed with the primary/ventilation air and the mixed air (5) is discharged into the room.

The FAP is a new packed DOAS (Dedicated Outdoor Air System) from Applied Air. This unit is the product of over 6 years of research and design and was designed from the ground up to fully comply with the ventilation standards set forth in ASHRAE 62.1. Compliance with this standard is a prerequisite for LEED certification. The FAP is a modular unit that contains many features that historically were only available in custom units. These features include:

▪ Our exclusive DHTD™ (Digital High Turn Down) burner (Patent Pending) with turn-down ratios up to 100 to 1. The most energy efficient indirect fired burner available.
▪ Powerful plenum fan section that can produce up to 6"wg of static pressure. Long duct runs are no problem for the FAP.
▪ MERV 7 filters standard with MERV 15 filters available for providing fresh clean ventilation air to your building.
▪ Up to 6 rows of DX coil. These coils are essential to insure that the air you bring in to your building is cool and dry.
▪ Patented ApdaptAire™ DDC controls that are BACnet, LON, N2, and modbus compatible
▪ Up to 60 tons of DX cooling capacity utilizing the environmentally friendly 410A refrigerant.
▪ Available re-heat coil option enables neutral air while complying with ASHRAE 90.1.

The Hurricane™ Wind-Driven Turbine Gravity Ventilator allows users to ventilate their commercial or industrial building without the need for a powered roof exhaust fan. The unit requires no electrical or maintenance costs to operate, providing a 2-3 year payback on investment. It also offers a lower first cost because wiring, starter, and associated electrical costs are eliminated. With its lightweight aluminum design, no framing is required.

Aluminum construction available. 12", 24" and 36" throat sizes with various accessory options.
