The Cool Ceiling technology with KARO has been refined and successfully utilized in Europe for over 15 years.
The principle is to create a cool or warm ceiling surface in order to condition a room by the most natural way: Radiation.
In buildings of office space, executive floors, architecture cabinets and all offices where people remain seated most of the time, the degree of comfort to be achieved is critical and directly linked to the people productivity.
Studies have proven that working in a quiet and comfortable atmosphere without draft increase the productivity of the people up to 50% and even more if we compare to simpler systems, enhance the creativity and the imagination.
With the conventional systems in summer, blast of cold air will cool down the human body and the room walls with high air volumes displacements. In our case, the cold ceiling surface will directly cool down the different heat sources in the room by radiations. A small ventilation is foreseen in addition to bring the necessary fresh air for hygienic and dehumidification purpose.
As a result, human body heat is naturally dissipated, no big air volumes are involved, no draft, lesser risk of disease, comfort in enhanced and so, productivity is improved. In addition to the comfort improvements, the KARO Cool Ceiling has a deep impact on energy savings and floor-to-floor height reduction in terms of building construction. Consequently, the solution is the most economic in terms of investment costs. A theoretical study as well as a direct application in a Mock-up office in Hong-Kong can be downloaded from the website, showing concretely those issues.
Water circulates in thin capillary tubes, the KARO Mats, or copper pipes, which are installed in the room ceiling.
Those Mats create a cool or warm surface and so, condition the air using a natural principle: radiation (cooling emission about 80 W/m2, heating emission about 90 W/m2).
In Europe, heating by the ceiling is now a common practice and since 15 years, cooling is also well developed, but very seldom used in other countries.
