Kühl- und Heizleistungsmessung von Raumkühl- & Heizflächenflächen

Kekelit is developing innovative, radiation-dominated TKS/TWS cooling and heating surfaces to maximise a building’s energy efficiency. This project empirically quantifies the thermal performance of these surface designs. Using a high-precision climate chamber and TAB walls, the ceiling’s performance is measured in isolation under realistic load conditions (simulated heat emission). The data validates models for efficient system design.

The increasing demands on the energy efficiency of buildings call for innovative, responsive and highly effective systems for regulating indoor temperatures. Kekelit is dedicated to the development and testing of novel concepts for room surfaces and cooling/heating surfaces based on radiation-dominated heat transfer with low thermal inertia – particularly in the field of dry-construction cooling/heating ceilings and walls (TKS/TWS).

For reliable design and maximum efficiency gains, precise knowledge of the thermal performance of these surfaces under varying operating and load conditions is essential.

This project aims to empirically quantify the thermal performance of innovative surface concepts from Kekelit, in particular the drywall cooling ceiling system (TKS).

The investigation is being carried out under controlled laboratory conditions in a high-precision climate chamber. This chamber utilises thermally activated building components (TAB walls) for active thermal limit control. This technology makes it possible to decouple wall loads from ceiling loads, thereby enabling an isolated and highly precise analysis of the performance of Kekelit surface systems.

The cooling/heating loads are simulated realistically, including through the introduction of heat via cooling load dummies that replicate the physiological heat emission of people.
