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