IQCA

Fläkt Woods unique comfort control makes it easy to adjust the air flow. Using the patented control rails, the air flow is adjusted by varying the size of the hole lengths in the supply air channel. This can be done simply in conjunction with balancing. A regulating damper is not normally necessary.

The adjustable hole lengths permit different air diffusion (two-way, one-way and intermediate positions). The easy regulation of the air diffusion and capacity make it possible to adapt to future changed conditions. On delivery, the hole lengths are open to their maximum extent as the starting point for future balancing.

Properties

• Simplifies balancing of the air flow
• The comfort control is adapted to the respective chilled beam and is thus not of the same type for the different chilled beams
• Easy to change the airflow for changed conditions
• The adjustable hole lengths permit different air diffusion (twoway, one-way and intermediate positions).

The FPC (Flow Pattern Control) function for the IQ chilled beams provides high flexibility. The combination of flow pattern control (FPC) and the patented comfort control gives the IQ beam unique characteristics.

FPC provides the possibility to adjust the air flow pattern at different angles, 0 – 15 – 30 – 45, through built-in vanes and adjustable rails. The different directions can be achieved in sections of 300 mm within the beam. The flow pattern can easily be adjusted and the beam.

IQ Beams with FPC function are optimized for minimal noise and pressure drop.

Properties

• FPC (Flow Pattern Control) is available for the ASTRA, STELLA, WEGA, IQID, IQFD, IQFE, IQCA and IQTA Chilled Beams
• The airflow can be adjusted up to 45 degrees through built-in vanes and adjustable rails
• Different directions can be achieved in sections of 300 mm in the beam

Construction and function
Cassette chilled beam IQCA is designed for ceiling mounting, and it is suited for standard 600 mm or 1200 mm ceiling modules, both in length and width, which means that it is flush with the ceiling surface. IQCA has the same unique function as other chilled beams from Fläkt Woods and is equipped with comfort control and has control equipment as accessory.

The combination gives good flexibility when dimensioning the indoor climate. The air flow can be adjusted by means of patented adjusting rails, comfort control, that changes the length of the holes in the primary air channel. This can easily be done with simple adjustments. The adjustable hole lengths allow different air distribution patterns (one-way, two-way, three-way, and between).

The simple adjustment of air distribution and capacity makes it possible to adapt to changing conditions in the future. Before delivery, the hole lengths of standard beams are preset at the longest possible position to provide a starting position for later adjustment.

The cassette chilled beam IQCA is equipped with Coanda Safety Control. It can be varied between high capacity setup (front in lowest position), normal capacity setup (front in middle position) and safety setup (front in highest position). This function is necessary in the area of low air flow to garantee a good indoor climate. It guarantees adhesion of the air stream to the ceiling. High capacity setup corresponds the front in lowest position and should be avoided below 60 Pa.

Material and surface finish
The casing is mainly made of galvanized steel sheet. The frontplate is powder painted in white. The standard colour RAL 9010 corresponds to NCS 0502-Y, gloss level 30. The coil made of copper tubes and aluminium fins, connection size is 12 mm Øout (thickness 1 mm).

Maximum working pressure 1.6 MPa.
