At our East Midlands Headquarters we have a 6.5m x 4.5m x 3.5m high state-of-the-art climatic testing facility at the disposal of our clients. This purpose built facility enables highly accurate measurement of the many variables that may be important to our clients, including:

In order to determine the performance of the chilled beam or radiant heating panel, all Frenger products undergo exhaustive laboratory testing.
The well-recognised Scandinavian ‘V Method’ is used for this type of comparative testing. The main features of this testing regime are:

• test specimen installed in a ‘room-within-a-room’
• heating or cooling sources introduced between the two rooms
• product capacity and air velocities can be measured
• the room is designed to create minimal temperature gradient

Product testing will establish the cooling or heating capacity of the individual product, however it makes no allowance for asymmetrical heat sources (hot or cold perimeter wall), temperature gradients in the space or the effect of the ventilation system. Therefore, in order to provide a more representative measurement of the indoor climate for any given project it may be considered appropriate to test the specified environment using physical modelling techniques. This will necessitate building a ‘mock up’ of the ceiling arrangement, together with the heating / cooling device, appropriate heat loads, lighting, solar gain, air delivery and air extraction.

The Frenger climatic testing facility is built to the very latest standards, and has been calibrated by the independent testing agency BSRIA. The facility has the capability to test in accordance with the requirements outlined in:

• DIN 4715-1 (chilled ceilings)
• EN 14518 (draft standard - passive chilled beams)
• EN 14037 (ceiling mounted radiant heating)

The company also has full laboratory testing facilities relating to air calorimetry and heat transfer within the office space.
