International. In the summer of 2015, a pilot experience took place at the Fairmont Rey Juan Carlos I hotel in Barcelona, the aim of which was to compare different air conditioning systems with a reference system consisting of a fancoil with a power of 5,350 kcal/h under Eurovent conditions. One of the solutions that were tested has been the Radiant Roof Uponor Teporis Panel.
The test has been supervised and certified by TÜV NORD Cualicontrol and the conclusions of its ZA 0616 report state a 48% reduction in energy consumption compared to the reference system.
Taking into account the conditions in which the installation has been operating, such savings would be much greater with a system specially designed for the radiant ceiling system.
This claim is supported by the fact that, in the system designed for the radiant roof, the cooling water would be circulated around 15 °C instead of the 7 °C required by the fancoil system.
In addition, the operation at variable water flow would reduce the consumption of the circulating pumps as the comfort conditions were reached and the inertial nature of the system would reduce the power of the installed generators by up to 30%.
Ventilation flows would also be reduced with the use of air quality probes, and air conditioners can be used to adjust the ambient relative humidity and increase the performance of the radiant ceiling when conditions are adverse.
The entire test was developed with the installation running in Cooling Mode.
