VARICOOL TKM-S

Radiant textile ceiling sail

The VARICOOL TKM-S radiant textile ceiling sail is a water-based climate ceiling system. In combination with the CAURUS Hybrid system, it combines very high heating and cooling capacity with supply air distribution and advanced sound absorption values.

In combination with CAURUS, the building mass is additionally integrated into the overall thermal concept based on the thermo-active building system principle. The building mass can be used as an additional thermal storage mass.

VARICOOL TKM can also be designed as a closed ceiling.

Room air distribution with the CAURUS Hybrid system

With supply air volumes of up to 70 m³/h per linear metre, the supply air is introduced horizontally into the room above the textile sail. High-performance induction nozzles support the entrainment of room air on the opposite side of the sail and the thermal exchange with the concrete ceiling.

Heat stored in the building mass can be removed at a later time. Depending on the operating conditions and system concept, free cooling can also be used for this purpose. The air distribution supports even mixing of the room air and a balanced temperature profile.

-> This climate ceiling system is only available in Switzerland.

Basis for assessment

Cooling capacity

The cooling capacity corresponds to the amount of energy per second removed from the room via heat radiation and convection. It is determined in accredited climate laboratories in accordance with SN EN 14240.

For comparison: the heat emitted by a person in an office via radiation and convection is approx. 70 – 80 W; the heat emitted by a laptop is approx. 20 – 50 W.

Heating capacity

The heating capacity corresponds to the energy per second added to the room via heat radiation and convection. It is determined in accredited climate laboratories in accordance with SN EN 14037.

For comparison: The heat output of a person in an office via radiation and convection is approx. 70 – 80 W, whilst that of a laptop is approx. 20 – 50 W.

Sound absorption

As the largest unobstructed surface in a room, the ceiling is particularly well suited to sound absorption. The sound absorption class is determined in accordance with EN ISO 11654, based on measurements carried out in accordance with EN ISO 354 in accredited laboratories.

It serves as a parameter for acoustic designers to calculate the effect of a product on a room’s reverberation time.

Carbon footprint

The carbon footprint describes the greenhouse gas emissions associated with a product. These emissions are expressed as CO₂ equivalents. The life cycle stages considered are specified in the respective Environmental Product Declaration and its defined system boundaries.

An Environmental Product Declaration (EPD) transparently presents various environmental impacts of a product based on a life cycle assessment. The calculation is carried out in accordance with the standards and methodological requirements specified in the EPD. Where stated, the EPD is verified by an independent third party.
