New induction unit VFK (Chilled beam)

A chilled beam is an induction unit that incorporates air diffusers. This terminal unit incorporates the following elements:
• Primary air plenum, with single or multiple spigots for connection of primary air to a series of nozzles.
• Cold water battery (installation with two pipes) or cold and hot water batteries (installation with four pipes).
• Linear diffusers, one on each side of the battery, for discharge and distribution of the mix of primary air and induced air.
As it passes through the nozzles, primary air induces the adjacent air, known as secondary air, which passes through the battery cooling, or warming and cooling, as appropriate, which mixes with the primary air before being distributed by the diffusers.
As with all water-based air conditioning systems, chilled beams have the advantage of using water as a vehicle for the transport of cooling or heating energy to different areas, thus saving energy and space compared to fully airbased systems. (As water can carry the heating or cooling load more efficiently than air.)
Also, with VFK chilled beams the temperature of each room or area can be controlled independently, incorporating a 2 or 3 port valve in the secondary battery controlled by a corresponding thermostat.

Koolair manufactures chilled beams in a range of width’s and length’s which can be adapted to match existing false ceilings. The range includes VFK-300, VFK-600 and VFK-675 models for 300, 600 and 675 mm wide plates for false ceilings.
Each of these three models are manufactured in lengths of 900, 1200, 1500, 1800, 2100, 2400, 2700 and 3000 mm. All models are 200 mm high.

The range indicated enables the selection of units for primary air flow from 5 to 100 l/s with maximum sound pressure levels of 40 dB (A) and secondary battery power of up to 1800 W.
